The aim of the work was to study the basic productive traits of Saanen goats of Latvian selection in the order of their selection value: milk yield, fat and protein content in milk. These traits were investigated in the daughters from different goats-fathers. Materials and methods of research. The study was conducted at "Grandmother’s Goats" breeding farm, Galaiky village, Tetiiv district, Kyiv region on Saanen goats of Latvian selection. From mid-spring to mid-autumn the goats grazed and were kept in a corral. In winter, the goats were indoors on deep litter. Milking was twice a day into milk pipeline, it took place in the milking room with 12 seats. The farm is provided enough by coarse, succulent and concentrate feeds. It is considered that the winter diet of dairy goats is hay, twigs, concentrate feed, root vegetables, and mineral supplements. The primary livestock data of milk production in 41 goats for seven lactations were considered. The basic selection traits were studied in the order of their breeding value: milk yield, fat and protein content in milk. The same traits were investigated in terms of fathers of milking goats. The obtained results were processed statistically by N. A. Plohinskiy (1970). Results of research. The research results show that milk yield of Saanen goats of Latvian selection varied depending on lactation. It was found that the milk production during the 1st lactation was 565 kg, fat content in milk – 3.2% and protein content – 3.0%. Milk yield per lactation tended to increase – from the 3rd to 6th lactation inclusively, as compared with the 1st and 7th. The maximum level of milk yield was during the 6th lactation. The differences in milk yield between the 6th and the 1st, 2nd, 5th and 7th lactations are significant with the second degree of reliability. Significant coefficient of variation for milk yield (20-35%) gives reason to consider it possible to conduct the selection by this trait. Several other data are presented by T. Orlovskaya. She considers that goats produce maximum milk yield on average after the 3rd parturition. Milking ability of goats after the 5th-6th lactation begins to fall gradually. She also thinks that biological value of milk is reduced with increase in milk yield, namely reduced fat content and, in some cases, changing the taste of milk. Subsequently, the fat content in milk during the 2nd-4th lactations increased by 0.1%, and during the 5th lactation it reached the maximum level – 3.6%. The protein content in the investigated goat milk was small and ranged from 3 to 3.1%. Differences in fat and protein content during all the lactations were unreliable. Ratio of fat content to protein content in Saanen goats’ milk was studied for seven lactations. It was found that the ratio of fat to milk for all the seven lactations did not reach the optimal levels. This is lack of milk quality of the investigated goats. Milk yield, fat and protein content in milk of daughters of four Saanen billy goats were investigated to determine the influence of fathers on the daughters’ productivity. Analysis of milk productivity data for daughters of goats Amors 046062340091, Wicks 030810040238, Priers 0460623640427 and Frends 038028540074 showed that the highest milk yield was in daughters of Amors 046062340091 – 622 kg. Several less milk yield (590 kg) was in the daughters of Frends 038028540074, and the lowest milk yields were observed in daughters of Wicks 030810040238 and Priers 0460623640427. Thus, daughters’ milk yields depend essentially on fathers. At the same time the fat and protein content in the milk of daughters from different fathers is almost identical. This should be taken into account at matching billy goats for breeding stock of goats. In our research of milk yield of daughters from different billy goats there was a significant difference, but protein and fat content in daughters’ milk almost was no different. Thus, the findings don’t always coincide with the data given in the literature. This concerns with the milk production of Saanen goats and its quality (fat and protein content). Earlier, we have shown that Saanen goats’ milk had a little lower density than in Lamancha, Russian, Nubian, Alpine and Megrelian goats. Protein content was at level of 3.85%, or 1.4% greater than in Russian goats’ milk, but 0.15% less than in Lamancha, 1.23% less than in Nubian, 0.4% – in Alpine, and 1.65% ­– in Megrelian goats’ milk. The fat content in goat milk of the compared breeds was also the lowest (by 1.85% than in Lamancha, by 0.79% than in Russian, by 0.97% than in Nubian, by 0.57% than in Alpine and 1.12% than in Megrelian breeds). Also, content of dry milk residue was low (0.67-1.48% less). Despite these differences in milk yield of goats, research in this area should be expanded in order to determine the prospects for further goat breeding of certain breeds. Conclusions. Milk yield per lactation tended to increase – from the 3rd to 6th lactation inclusively, as compared with the 1st and 7th. The maximum level of milk yield was during the 6th lactation. Significant coefficient of variation for milk yield (20-35%) gives reason to consider it possible to conduct the selection by this trait. The differences in the level of milk production of daughters from different goats were revealed that should be taken into account at matching billy goats for breeding stock. In Ukraine goats’ milk yield of different breeds requires further study.

Effective interbreed selection, which involves family breeding, is an important task today, because the presence of valuable families characterizes the degree of herd selectivity and the level of breeding in it. Therefore, the purpose of our research was to conduct a retrospective analysis of the zootechnical accounting data of dairy productivity and breeding value of cow families at highly productive herd of Public joint-stock company “Stud farm “Stepnoy”, in Kamyansko-Dniprovskyy district of Zaporizhzhya region created by crossbreeding of the females of the Ukrainian Black-and-White dairy breed with Holstein breeders. The analysis included 45 families, with a head count of 8 to 19 heads, including foundation cows. Malta family UA2300205993 had the maximum number of descendants (6 daughters, 6 granddaughters and 6 great-grandchildren), and Malta family UA2300241359 (3 daughters and 3 granddaughters) – minimal. Found to be that the families under control were characterized by a significant level of differentiation in milk yield and fat and protein content in milk. The Mazi family UA230023375 was the best by milk yield, the Lemonka family UA2300233684 – by the fat in milk, by the protein in milk – Nasypa UA2300222571. At the same time, foundation cow Kviten UA2300077306, Nasypa UA2300222571, Yana UA2300248883, Lamysta UA2300198909 and Sokyra UA2300241365 had the most highly productive daughters; their milk yields for higher lactation was in the range 11143.5–12780.0 kg. At the same time high-productive foundation cows did not always receive high-productive daughters. In particular, 3 daughters of the foundation cow Krovlya UA2300229133, whose milk yields for higher lactation was 12671 kg, had lower milk yields by an average of 2704.7 kg. However, foundation cows with low milk yields level had daughters who had this rate significantly higher, including the foundation cow Kviten UA2300077306, Toskana UA2300077167, Liga UA2300034958, Maket UA2300241388 and Manilka UA2300233701, whose highest milk yields level for the highest lactation was in the range 5625–7701 kg, and ho had daughters whose milk yield was higher than their mothers by an average of 4858.5; 3975.3; 3704; 3299.5 and 3186.7 kg respectively. The granddaughter of the experimental foundation cows ranged from 8413.0 to12942.6 kg, fat content in milk – from 3.50 to 4.13% and protein content in milk – from 3.05 to 3.29%, and the figures of great-grandchildren were respectively 7114.0–11991.3 kg, 3.49–3.92% and 3.00–3.29%. It should be noted that 15 foundation cows gave granddaughters with an average milk yield of over 10000 kg, 13 with a milk yield more than 11000 and 3 – with a yield of more than 12000 and only 2 foundation cows had second generation descendants with an average yield of less than 9000 kg. The grandchildren of 14 foundation cows had over 10000 kg of milk yields, and 7 over 11000 kg. The breeding value of the foundation cows by the milk yields was within -497 (Liga UA2300034958) – +1614.4 kg (Tsykl UA2300233484), by the fat content in milk – within -0.098 (Hanh UA2300233710) – +0.280% (Stezhka UA2300205863) and by the protein content of milk within -0.073 (Maket UA2300241388) – +0.053% (Stezhka UA2300205863), breeding value by the above indicators of their daughters were accordingly within -554.9 – +819.3 kg, -0.065 – +0.095% and -0.038 – +0.045%, granddaughters – within -326.3 – +786.2 kg, -0.048 – +0.145% and -0.033 – +0.025% and to a great-granddaughters – within -670.5 – +590.3 kg, -0.067 – +0.043 and -0.043 – +0.030%. The most valuable in the herd relation by milk yield appeared to be Mazi family UA2300233755, Lemonka family UA2300233684 – by the fat content in milk and by the protein content in milk – the Nasypa family UA230022257. Among evaluated families by the nature of changes in breeding values in generations 31 (68.9%) were progressive, 4 (8.9%) were stable and 10 (22.2%) regressive. The prediction of the efficiency of dairy cattle breeding and prediction of certain changes by the productivity indices of subsequent generations can be made by correlation and regression coefficients of the main features: milk yield, fat content, and protein content in milk. The highest and most likely coefficients of correlation (r = 0.39) and regressions (R = 0.42) were observed between the milk yield of foundation cows families and their daughters. Each succeeding generation had declined and the indices of descendants of the third generation were unreliable. Influence of foundation cows in future generations, depending on the generation and nature of the features of milk productivity, was also different. Milk yield (h2 = 0.26–0.79) was characterized by the highest and most reliable heritability estimate, much lower and unreliable in the second and third generations – the fat (h2 = 0.10–0.22) and protein content in milk (h2 = 0.12–0.24). It indicates that in the controlled herd more attention is paid to milk yield focus breeding. Therefore, to improve family fat and protein content in milk it should be used breeders whose mothers have high fat and protein content in milk.

Background: Several single nucleotide polymorphisms had been detected in goats and for the researchers it is important to reveal candidate genes with substantial effects on the traits of economic importance. The aim of this study was to investigate the association between LPL, STAT5 and AGPAT6 gene polymorphisms and milk traits of goats. Methods: We investigated about 204 goats, four different breeds (Czech White Shorthaired, Saanen, Anglo Nubian, Alpine) and two crossbreeds (Saanen and Alpine, Saanen and Anglo Nubian). The milk samples were analysed using spectrophotometers LactoScope 550 and LactoScope FTIR (Delta Instruments, the Netherlands). The somatic cell count (SCC) in milk was determined by flow cytometry method using the Somascope CA-3A4 (Delta Instruments, the Netherlands). Variations of the goat AGPAT6, STAT5, LPL genes were detected by PCR-RFLP method. Result: Analysis of AGPAT6 gene revealed that goats with GC genotype had higher milk yield, fat content and lactose content; goats with CG genotype had higher protein content. STAT5 gene analysis showed that goats with CT genotype had higher milk yield; goats with CC genotype had higher fat content and lactose content; goats with TT genotype had higher protein and urea content and also SCC. According to LPL gene analysis, goats with CC genotype had higher milk yield while goats with GG genotype had higher fat and protein content. The highest milk yield was estimated in Saanen and Alpine crossbreed goats while the highest milk fat and protein content was estimated in Anglo Nubian goats.

Abstract. The aim of this study was to estimate the effect of variation in the fatty acid binding protein 4 gene (FABP4) on milk production traits in Greek Sfakia sheep. Polymerase chain reaction – single-stranded conformational polymorphism (PCR-SSCP) analysis was used to genotype a total of 374 Sfakia ewes for two regions of FABP4 located around exon 2–intron 2 (Region 1) and exon 3–intron 3 (Region 2). Each month, for a period of 6 months, milk samples were collected from the ewes to measure total milk yield, fat content, protein content, lactose content, non-fat solid content, pH, and somatic cell count (SCC). A general linear model was used to test the association between the variation observed in FABP4 and milk production traits. Four gene variants (A1–A4) were found in Region 1 and two variants (C1–C2) were found in Region 2. In the first region, the FABP4 genotype significantly affected (P<0.05) non-fat solid levels, fat content, and SCC. The presence of the A2 variant was significantly associated (P<0.05) with decreased SCC, while the presence of A4 was significantly associated with decreased milk yield (P<0.01), increased non-fat solid content (P<0.05), decreased fat content (P<0.01), increased lactose content (P<0.05), and increased pH (P<0.05). In the second region, FABP4 genotype had an effect (P<0.05) on protein content and the presence of the C2 variant was associated (P<0.05) with increased protein content, decreased SCC, and lower pH. The results suggest an association between variation in ovine FABP4 and milk production traits in Greek Sfakia sheep. Nevertheless, further analyses in independent sheep populations of increased size will strengthen these findings.

In Tunisia, dairy farming faced several problems limiting the improvement of the milk sector, mostly at the level of small farmers. These difficulties are related to the milk quality affected by the feed quality distributed throughout the year. This study aimed to evaluate the effect of rations and seasons on daily individual milk production (DIMP) and some physicochemical characteristics (Fat content: FC, Protein content: PC, Urea concentration: UC, Total Solids: TS). A survey and milk samplings were performed on 135 farmers. Collected data were treated by the variance analysis using the GLM procedure of the SAS system. This study allowed to identify four types of ration: TR1: Concentrate (CC)+Green Forage(GF), TR2: CC+Dry Forage (DF), TR3: CC+GF+DF and TR4: Diet containing Silage (S), used by farmers with the frequencies of 14.82, 37.19, 44.6 and 3.38 % respectively. The highest DIMP (P<0.0001) was obtained by TR1 (17.3 kg/day) and the lowest (13.6 kg/day) by TR2. TR4 allowed FC, PC (P<0.05) and TS (P<0.01) higher (3.84, 3.14 and 12.31 % respectively) than those obtained in the other rations. The UC (P<0.0001) was the highest in TR1 and TR3 (32.05 mg/dL) followed by TR4 (28.3 mg/dL) and TR2 (26.2 mg/dL). Concerning the season effect, the highest DIMP (P<0.0001) was obtained during spring (17.7 kg/day), the lowest was during autumn (13.1 kg/day). The FC (P<0.05) was the lowest in winter (3.52 %). The PC (P<0.01) was higher during autumn and winter (averaged 3.07 %). The UC (P<0.0001) was the highest in spring (32.23 mg/dL) and the lowest in autumn (25.67 mg/dL). It was concluded that milk parameters were in the acceptable ranges comparatively to the national averages.

The Relationship

The objective of the present study was to explore the effect of the level of inbreeding on milk efficiency of cows and on the content of milk components (fat and protein) in the 1st standard lactation period (305 days). The level of inbreeding (Fx) of inbred cows ranged between 1.25 and 12.5%. Efficiency parame- ters of inbred cows were compared with their contemporaries – half-sisters after the father (n=2567), raised on the same farm whose first lactation ended in same year. Out of the total database (567,036 cows) created in 1980–2002 we incorporated 885 inbred cows. To allow detailed analyses the inbred cows were divided into 3 groups according to the coefficient Fx (1.5–2.3%, 3.0–5.0% and 8.0–12.5%). The database was evaluated using the analysis of variance with 8 fixed effects including the commercial type, own breeding value and breeding value of mother, average efficiency of mother, reproduction parameters (year and age at calving and interval between the 1st and 2nd lactation) and total number of lactations. The statistical programme SAS 8.2 – GLM procedure (Copyright c 1999–2001 by SAS Institute Inc., Cary, NC, USA) was used for statistical analyses. Compared to their contemporaries the 323 kg reduction of milk production of inbred cows with the lowest value of Fx (1.5–2.3%) was insignificant; the decrease in the relative content of fat and protein was insignificant by 0.01 and 0.02%, respectively. Comparisons between contemporaries and inbred cows with Fx at the level of 3.0–5.0% showed a highly significant 407 kg reduction in milk efficiency. The fat content in milk of inbred cows increased by 0.11% (p<0.01) and the protein content by 0.03% (p<0.05) compared to their contemporaries. The reduction in milk production of inbred cows with the highest level of Fx (8.0–12.5%) was significant, i.e. –572 kg; the fat content increased insignificantly by 0.02%, while the protein content was the same in inbred cows and contemporaries. Comparisons of the milk production of inbred cows at various levels of Fx, taking into consideration the fixed effects, showed that the differences were most marked between groups Fx=1.5–2.3% and Fx=8.0–12.5%; the reduction in milk efficiency was –731 kg. A Fx coefficient higher by 1% reduced the milk efficiency of cows by 90.07 kg, while the fat and protein content increased by 0.001% and 0.002%, respectively.

Lactating Goats

Twelve adult lactating goats and sheep (2 to 2 ½ years old) comprising three groups of four each of West African Dwarf (WAD) goats and sheep and Yankasa ewes used for a nine week trial. The animals kidded and lambed between January and March. During these periods the udder sizes of the dams were measured weekly before hand milking thrice a week to derermine the milk yield. Samples of the milk were analysed for their composition. The results showed that the udder size increased with increasing milk yield (112 – 248ml) up to the peak of lactation which was between weeks 3 and 4 after parturition. Thereafter it decreased in size till the end of the experiment. The coefficient of variation (CV) of the udder size was influenced by breed. Udder size was positively correlated with milk yield. Milk yields were generally low or and ranged between 39 and 70ml and this was dependent on the behavior of the lactation curve. The milk protein and ash contents for the three breeds were comparable to those of the temperate breeds. Though Yankasa sheep exhibited the highest milk production potential, yet the peculiar characteristics of goat milk cannot be overlooked.

Increasing the number and improving the quality of milk and meat are the main goal and main focus of cattle breeding. The purpose of our research was to study milk and meat productivity of animals of different breeds which are bred in Western Ukraine. The researches were conducted at eight farms in Western Ukraine with cows and bulls of Ukrainian Black-and-White Dairy, Ukrainian Red-and-White Dairy Red, Ayrshire, Red Polish, Simmental, Carpathian Brown, Limousin and Volyn Beef breeds. Evaluation of milk production of cows of dairy and dual-purpose breeds (yield, fat content in milk, the amount of milk fat) was carried out according to the data of zootechnical accounting (during the past 20 years) for the I, II, III, IV, V and the best lactation. The chemical composition of milk was determined in 2-3 months of lactation period in cows of full-age (the III lactation) for each breed using milk analyzer "EKOMILK TOTAL". Researches of meat quality were conducted based on a control slaughter of 3 bulls at the age of 15 months for each breed. Live weight before slaughter was determined after a 24-hour hunger exposure. Weight of pair carcasses, internal fat weight, slaughter weight, carcass yield, the output of internal fat, and slaughter output were determined after slaughter by G. T. Shkuryn method. Weights of flesh, bones and tendons were determined in the semi-carcasses. Ratio of meatiness, calculated as the ratio of flesh to bones and tendons, and muscle-bone ratio, calculated by dividing flesh weight to weight of bones, were determined to assess meat quality. Average sample of mincemeat from three ribs cuts was selected for the chemical analysis. The samples were tested on contents of moisture, dry matter and ash by conventional techniques, of protein content – by Kjeldahl method, fat content – by Soxhlet method. The results of the researches were processed by method of variational statistics using Microsoft Excel and "Statistica 6.1" by N. A. Plohynskiy. It was established that cows of the studied breeds differed in terms of milk production; it is primarily due to the fact that some of them belong to the specialized breeds, others – to local (less productive). However, all of them by milk yield, fat content in milk and the butterfat number prevailed relevant standards of these breeds (exception – fat content in milk during the first lactation of the Ayrshire cows). Highest milk yield was observed during the third lactation at the most animals of the studied breeds and only for Ukrainian Red-and-White Dairy and Simmental breeds – during the fourth lactation. Milk yield of Ukrainian Black-and-White Dairy cattle, depending on lactation was within 3970.9-4537.9 kg, fat content in milk – within 3.67-3.71% and the number of milk fat – within 149.5 -168.0 kg; Ukrainian Red-and-White Dairy – in accordance within 3503.0-4471.8; 3.76-3.78 and 132.4-168.6; Red Polish – within 2838.4-3698.4; 3.70-3.73 and 107.9-138.6; Ayrshire – within 4034.3-4337.0; 4.0-4.12 and 165.4-181.7; Simmental – within 3026.4-3810.2; 3.76-3.81 and 113.6-145.0 and Carpathian Brown breed – within 2700.5-3384.4 kg; 3.69-3.85% and 99.8-125.9 kg. The results of the control slaughter indicated that the bulls of the studied breeds differed in slaughter qualities and morphological composition of carcasses. The Ukrainian Red-and-White Dairy bulls among dairy breeds were characterized by the highest slaughter output (55.2%) and carcass yield (56.7%), the Simmental bulls (58.1 and 59.7% respectively) – among the dual-purpose breeds, and the Limousins (63.2 and 61.4%) – among the beef breeds. The highest percentage of flesh was observed at the semi-carcasses of these animals. Higher contents of protein and fat in meat of the Polish Red bulls were observed among the dairy breeds and in meat of the Simmentals – among the dual-purpose ones. Higher protein content was in meat of the Limousins among the beef breeds and fat content – at the animals of Volyn Beef breed. Ratio of meatiness at the animals of the dairy breeds was within 3.18-3.27, muscle-bone ratio – within 3.83-4.00, these figures were 3,38-3,51 and 4,15-4,33 respectively at the bulls of the dual-purpose breeds, and for the beef breeds – 6,42-6,78 and 6,26-6,59.

The studies were conducted on high-producing cows of Precarpathian innerbreed type of Ukrainian Red-and-White Dairy cattle and their progeny, according to zootechnical accounting in private farm enterprise "Mamayivske" in Kytsman district of Chernivtsi region. It was established that during the period from 1995 to 2010 the farm had 20 cows with milk yields over 8000 kg. The highest milk production by the best lactation had cows Maratka 3235, Vorovka 5982 and Chaika 3839, their milk yields were 10586; 9380 and 9008 kgrespectively, fat content in milk – 3.61, 3.79 and 3.77% and fat yield – 382.2, 355.5 and 339.6 kg. The cows had the highest milk yields mostly during the third lactation, and milk yields on average reached record in 3.85 lactations. High-yielding cows belonged to 5 bloodlines: R. Sovering 198998, P. Astronaut 1458744, R. Citation 267150, Rigel 352882 and Hanover 1629391. The most numerous one was Astronaut bloodline (11 cows). Daughters of Tyulpan 7451 (R. Sovering bloodline) had the highest level of milk production during the best lactation. They predominated in milk yield during the best lactation over Gybrid’s daughters (Citation bloodline) by 156 kg, T. Tourist’s daughters (Rigel bloodline) by 401 kg, Sekret’s daughters (P. Astronaut bloodline) by 473 kg and M. G. Horizont’s daughters (Hanover bloodline) by 812 kg , by fat yield – by 4.6, 8.6, 9.9 and 26.8 kg, respectively but they were inferior by fat content in milk by 0.02, 0.07, 0.09 and 0.04%. Sekret’s daughters had higher fat content in milk. By this trait, they predominated over Hybrid’s daughters by 0.07, T. Tourist’s daughters – by 0.02 and M. G. Horizont’s daughters – by 0.05%. The average breeding value of bulls, daughters of whom had milk productivity of more than 8000 kg, was +276 kg. The highest milk yields were in cows whose mothers belonged to P. Astronaut and Hanover bloodlines and fathers – to R. Sovering bloodline (daughters’ milk yield was 9303 and 9008 kg respectively). High milk yield (8842 kg) also was in cows whose mothers belonged to P. Astronaut bloodline and fathers – to R. Citation bloodline. The best cows by fat content in milk were obtained from a combination of bloodlines V. Ideal – P. Astronaut (3.80%), Rigel – Rigel (3.80%), V. Ideal – Rigel (3.78%) and V. Ideal – Rigel (3.78%). Coefficients of repeatability for milk production decreased with increase in period between the comparable lactations. By milk yield for I-VI and the best lactations they were within 0.206-0.495, and by fat content in milk – within 0.337-0.469. The better daughters by milk yield not always were obtained from high-yielding cows and, on the contrary, the worse ones – from low-yielding cows. Most cows with high milk yields were from mothers with yields not exceeding 6000 kg of milk, and only with average milk performance of mothers not more than 7281 kg of milk, their daughters predominated in milk yields. With the increase in average productivity of mothers to 8456 kg of milk or more, daughters were inferior to their mothers by1180-3454 kg of milk, but, in all cases, they had a higher milk yield than the average for the herd. Positive correlations were found between mothers' milk yield and milk yield, fat content in milk and fat yield of their daughters, but their values partly depended on mothers’ productivity. The highest correlation coefficients between productivity of daughters and mothers were observed at the mothers’ yields not higher than 6999 kg (r = 0.221-0.273), and the lowest – at mothers’ yields over 9,000 kg (r = 0.155-0.182). It was found that bull Arbat 1577, estimated on milk production in 69 daughters, had the highest breeding value. The rank of its breeding value was P5 (improver "excellent"). Cows Maratka 3235 (+3204 and +1860 kg), Krona 8490 (+2202 and +1315 kg) Vorovka 5972 (+1710 and +1121 kg), Kava 5450 (+1626 and +1004 kg) Shchoka 5870 (+1602 and +937 kg) had the highest breeding value in terms of best lactation and based on three sources of information, respectively.

The results of the study of milk production and morphophysiological properties of the uterus of heifers of the red-and-white breed for 100 days of lactation in comparison with the heifers of the Simmental breed are presented. For 100 days of lactation from heifers of the red-motley breed, 2096 kg of milk each were obtained, with a fat content of 3,9 and a protein of 2,9%, from simmental fat, respectively, 1363,2 kg, with a fat content of 3,7 milk and protein of 2,9% First heifers of the red-motley breed exceeded their peers in milk production by 732,8 kg (34,9%) with a highly reliable statistical difference (B3 ≥ 0.999). Reliability (td=1,6) at zero threshold (Bo> 0,90) was also noted for fat content in milk. The protein content in milk in first-calf cows of both groups was at the same level – 2,9%. It has been established that the morphological features and functional properties of the udder are fairly consistently inherited by the offspring. Therefore, by selection and selection, it is possible to obtain animals with bath-like and cup-shaped forms of the udder, uniform development of quarters, with full milk yield. The shape of the udder is one of the main breeding traits characterizing the suitability of cows for machine milking, which is most closely associated with productivity. In our studies, all the first heifers of the red-and-white breed had a bath-like and cup-shaped udder (65 and 35%). Simmental first heifers were inferior, in them 78% of the animals had a bath-like and bowl shape and 22% were round. When measuring the udder, it was established that the first-hens of the red-and-white breed had a wider, deeper udder with a large girth. Their udder was longer than that of the Simmental ones, by 1,4 cm, wider by 1,5, deeper by 1,7, and more by girth by 3,6 cm. The functional properties of the udder of heifers of the red-and-white breed were significantly better than those of the Simmental. One-time milk yield from them was higher by 5,7 kg and amounted to 10,8 milk. The lactation rate was also higher in the red-and-white first-calfs, and it was 1,794 kg / min. In the red-and-white heifers, a high positive correlation was observed between the milk yield and body weight – 0,76, among the Simmental ones – 0,22, and between the milk yield and the fat and protein content in milk, the negative correlation in both groups of animals. For measurements of the udder (length, width, and girth) and milk yield for 100 days of lactation, a positive correlation was found for both red-and-white and simmental healers.

Created Ukrainian Red-and-White Dairy and Ukrainian Black-and-White Dairy cattle have a desirable level of reproductive and productive qualities.  These breeds are competing successfully with animals of the European selection, so comparative study of pedigree and productive qualities of animals at one of the farms has practical value. The studies were conducted in the herd of “Oleksandrivske” SE RF at the animals of Ukrainian Red-and-White Dairy and Ukrainian Black-and-White Dairy breeds of Vinnytsia region. The animals of both breeds were kept under the same technological conditions in housing for livestock. It was taken into account milk production (milk yield, fat content in milk and milk fat) for 305 days of lactation. Expert evaluation of the exterior of first-calf heifers has been conducted for 2015-2016. Assessment of type of body structure of cows was conducted on 100-point scale. Fatness of cows was determined on 5-point scale. The analysis of genealogies of 37 bulls which had progeny in the herd was conducted by breeding index, discharge of breeding values and milk production of ancestors. Milk production of the animals of the herd was more than 6000 kg of milk for 305 days of lactation. Comparing milk yields, it was found that the animals of Ukrainian Black-and-White Dairy breed dominated Ukrainian Red-and-White Dairy cows of the same age. It is noteworthy that biological feature of cows to increasing milk yield with each subsequent lactation is positive. Thus, the Ukrainian Black-and-White Dairy cows after the second calving in comparison with the first calving increased milk yield by 380 kg and the animals after the third calving and older comparatively with the second one – by 425 kg more. Also the Ukrainian Red-and-White Dairy cows increased milk yield, respectively, by 348 and 358 kg. The average body measurements of the first-calf heifers were inferior by targeted parameters of Ukrainian Red-and-White Dairy and Ukrainian Black-and-White Dairy cattle from -0.3 cm (girth of metacarpus) to -7.8cm (height in the sacrum) in most cases.  The total number of points for type of body structure was 87.9 at the animals of Ukrainian Black-and-White Dairy cattle and, respectively, 87.0 at the Ukrainian Red-and-White Dairy cows; it corresponds to the assessment "very good". This indicates the high estimation of individual parts of the exterior. The cows of the herd had the required fatness. The average of this trait at animals of Ukrainian Black-and-White Dairy breed was 3.0 points and at the cows of Ukrainian Red-and-White Dairy cattle was respectively 3.4 points. The genealogical structure of the current herd of “Oleksandrivske” SERF consists of two female contingents. The animals of Ukrainian Black-and-White Dairy cattle were derived from 18 bulls belonging to 8 bloodlines. Most of animals belong to R.O.R.Elevation 1491007 bloodline – 45.4%, H.H.Starbuck 352790 and P.F.A.Chief 1427381 bloodlines – 14.4%. Qualitative characteristic of bulls used for the female livestock of the herd, shows that in the vast majority they are valuable breeding bulls. However, it should be noted that there are progeny derived from bulls with low breeding value in the herd. Thus, bull Matrix Red 136549448 had SI-7 and H- and Trubadur 343643346 had SI-50 and H-. The use of bulls for female livestock of the herd with low breeding value is unacceptable for further breeding work. Expectation of improving the breeding traits in progeny from such fathers is unlikely. It is planned to accelerate the reproduction of valuable genotypes and increase the rate of genetic progress at the herd using embryos transplantation this year. Donors of embryos will be their own breeding resources. Using this method will make it possible to exclude from the selection process animals with exterior defects and low-yielding cows. The considered aspects of selective breeding work indicate prospects of using Ukrainian Red-and-White Dairy and Ukrainian Black-and-White Dairy cattle. This applies particularly to increase of milk yield to 8000 kg and more per lactation. Bulls which will be used for breeding stock should have high rates of breeding values (SI +1000 and P4 and more). Especially it applies such features as fat content in milk and some exterior defects.
