In the Republic of Kazakhstan over the past decade positive changes have been observed in increasing the number of farm animals, increasing their productivity, and increasing the gross production of milk, meat and other products. At the same time the development of dairy cattle breeding is mainly due to the breeding of Black-and-White, Red Steppe, Simmental breeds and their intra-breed types as well as imported from abroad Holstein breed. The purpose of the research was to analyze ways to improve the intra-breed type Karatomar of Black-and-White breed in Northern Kazakhstan. Research work has been carried out on breeding animals such as Karatomar type cattle of Black-and-White breed in LLP “Experimental farm Zarechnoe” in the Kostanay district in the Kostanay region. The dynamics of growth and development indicators, reproductive traits of heifers of a new intra-breed type Karatomar of Black-and-White cattle have been studied. A comprehensive assessment of their economically useful traits in the first lactation, determined by the resistance of animals to climatic and forage conditions, the efficiency of breeding of animals of different genotypes has been conducted. It has been found that the replacement heifers – daughters of American breeding sires inherited precocity and showed higher growth energy after 6 months of age and continued to grow rapidly until 18 months. The advantage in metabolism was in the daughters of Holstein sires of the American selection Orbit 4078, and the increased immune status of the organism in the daughters of the sire of the domestic selection Yamal 975 as the most adapted to the conditions of Northern Kazakhstan. The best ability to increasing the milk yield, stable lactation activity, high milk productivity, gross content of dry matter and nonfat milk solids have been characterized by the daughters of sires of the American selection Orbit 4078 and Lowrider 4129. Analysis of economic indicators of milk production has been shown that from cows – daughters of sires Orbit 4078 and Lowrider 4129 for 305 days of lactation received 15,8 and 15,2 % more milk of base fat, the expenditures of EFU per 1 kg of production was lower by 10,2 and 5,9 %. A higher level of profitability has been observed in the group of daughters of the sires Orbit 4078 – 35,5 % and Lowrider 4129 – 33,1 %, which was 8,5 and 10,8 % higher than in the group of daughters of the sire Yamal 975.

In order to fi ll the existing protein defi ciency in the rations of farm animals in particular dairy cows it is necessary to input feed lupins as widely as possible in crop rotations. Lupin is a very versatile forage crop it can be used in feed as herbage, in the form of haylage, silage, in compound feed as a protein additive, as well as a green manure crop to increase soil fertility. Questions of protein nutrition should be to be quickly resolved, both in the production of protein and in its standardized rational use. Unbalanced protein rations increase feed consumption per unit of production, thereby increasing its prime cost. In the world soya is generally recognized as a protein feed, but in the Kaliningrad region as in most of regions in our country, it does not maturate being a heat-loving crop. Under these environments the inclusion of extruded lupine grain in the composition of energy-protein concentrates for the production of compound feed has become an alternative to replacing expensive soya. The researches have been carried out it the cattle farm of LLC “Temp” in the Guryevsky area in the Kaliningrad region (March-May 2019) on feeding lactating cows energy-protein concentrate from extruded grain of narrow-leaved lupine, fl ax, triticale, subjected to heat treatment on a press extruder. For this purpose two groups of lactating cows of Black-and-White breed (control and experimental) have been formed using the method of pairs of analogs per 11 heads in each. Cows of the control group have received the main ration of the farm, and cows of the experimental group in addition to the main ration have received compound feed with extruded energy-protein concentrate based on lupine. As a result of research, the positive infl uence of energy-protein concentrate based on lupine in compound feed on the dairy productivity of cows has been established. Recipes of concentrate and compound feed with concentrate for lactating cows, the volume of inclusion of components in the concentrate and in the compound feed have been calculated. During the experiment, the milk yield in the experimental group of cows has increased by 62,4 kg or 8,0 %, than in the control group. From the cows of the experimental group the conditional profi t has been received in the amount of 1684,8 rubles per head.

We studied protein metabolism in Holsteinized black-and-white cattle. The researches were conducted in the Kuzbass at OJC «Vaganovo». Blood sample was taken from each cow, according to generally accepted of methods and analyzed in the laboratory of biochemistry from Novosibirsk State Agrarian University by using standard kits of biochemical studies on a biochemical semiautomatic analyzer Photometer 5010 V5 +. The indicators of protein metabolism were established in the blood serum of Holsteinized black-and-white cattle in average values; creatinine was characterized by the lowest phenotypic variability. The greatest positive relationship was found between albumin/globulin coefficients and albumin (r = 0.765). The reference intervals were calculated for cows of the 3rd lactation of the Holsteinized black-and-white breed with a high level of milk productivity (9-10 thousand kg): total protein 62.02-87.58 g / l; albumin 21.05-36.09 g / l; urea 2.2-4 mmol / l; creatinine 50-71 μmol / l; albumin-globulin coefficients 0.35-1.16. The data obtained can be used for assess the interior of animals.

Изучен полиморфизм и определена частота встречаемости аллельных вариантов по генам пролактина (PRL) и соматотропина (GH) у коров в условиях двух племенных хозяйств Республики Татарстан. Объектом исследования были животные черно-пестрой породы первого (n=151) и третьего (n=168) отелов и холмогорской породы первого (n=160) и третьего (n=143) отелов. Проведено генотипирование коров по генам PRL и GH методом ДНК-диагностики. Установлено, что среди молочного скота преимущественно встречаются особи с генотипом PRL АА (70,0—77,5%), с частотой аллеля А гена пролактина — 0,83—0,87, аллеля В — 0,13—0,17. Встречаемость аллеля В была выше среди холмогорских коров (0,16—0,17). В стаде полновозрастных животных черно-пестрой породы имеется сдвиг генетического равновесия в сторону генотипов PRL AA и PRL BB (χ2=3,97; Р<0,05). В исследуемых стадах крупного рогатого скота выражено преимущество генотипа GH LL с частотой встречаемости 51,0—79,2%. Встречаемость генотипа GH VV у черно-пестрого скота составила 2,0—2,4%, у холмогорского — 5,6—7,0%. Аллель L гена соматотропина преобладает над аллелем V в обеих породах. При этом чаще встречаемость аллеля L GH среди коров холмогорской породы (0,28—0,29). У холмогорских коров больше представлены редкие и желательные аллели генов PRL и GH. Чтобы повысить встречаемость «предпочтительных» в хозяйственном отношении генотипов и аллелей ДНК-маркеров, необходимо в большей степени использовать быков-производителей с желательными аллелями PRL и GH, а именно В и V соответственно. The polymorphism was studied and the frequency of occurrence of allelic variants for the genes of prolactin (PRL) and somatotropin (GH) was determinedin cows in two bred livestock farms of the Republic of Tatarstan. The object of the study were animals of the black-and-white breed of the first (n=151) and third (n=168) calving and the Kholmogory breed of the first (n=160) and third (n=143) calving. Genotyping of cows for PRL and GH genes was carried out using method of DNA diagnostics. It was revealed that there were mainly individuals with the PRL AA genotype (70,0–77,5%)among dairy cattle, the frequency of the A allele of the prolactin gene was 0,83–0,87, the B allele was 0,13–0,17. The frequency of allele B was higher among Kholmogory cows (0,16–0,17). There was a shift in the genetic balance towards the PRL AA and PRL BB genotypes (χ2=3,97; Р<0,05) in the herd of full-age animals of the black-and-white breed. The advantage of the GH LL genotype was expressed with a frequency of occurrence 51,0–79,2% in the studied cattle herds. The occurence of the GH VV genotype was 2,0–2,4%in black-and-white cattle, 5,6–7,0% was in Kholmogorycattle. The L allele of the somatotropin gene predominated over the V allele in both breeds. Moreover, the occurrence of the L GH allele among cows of the Kholmogory breed (0,28–0,29) was more often. Rare and desirable alleles of the PRL and GH genes are more represented in Kholmogory cows. In order to increase the occurrence of economically “preferred” genotypes and alleles of DNA markers, it is necessary to use more stud bulls with the desired PRL and GH alleles, namely B and V, respectively.

The present study addresses the characteristics of the frequency and segregation of alleles determining the SNP 775C>T polymorphism within the bovine <i>ITGB2</i> gene in the Black-and-White cattle population as well as in two endemic breeds of Polish Red and Polish White-Back cattle population qualified to the international programme of genetic resource diversity preservation in farm animals. The SNP 775C>T polymorphism revealed three amplified restriction fragments of 31 bp, 77 bp and 108 bp, forming three genotypes <i>CC</i> (31 bp, 77 bp), <i>CT</i> (31 bp, 77 bp, 108 bp) and <i>TT</i> (108 bp). A group of randomly selected Black-and-White cows was characterized by a negligible percentage of homozygous genotypes <i>TT</i> (5.1%) and by a prevailing percentage of heterozygous <i>CT</i> (60.1%) and homozygous <i>CC</i> (34.8%). In contrast, the between breeds analysis revealed that cows involved in the programme of genetic diversity preservation had a high prevalence of homozygotes <i>CC</i> (Polish Red &minus; 55.9%, Polish White-Back &minus; 60.0%), and a low percentage of homozygotes <i>TT</i> (Polish Red &minus; 8.8%, Polish White-Back &minus; 5.7%) in comparison with the Black-and-White cattle population. The degree of homozygosity in groups of Polish White-Back cows (65.7%) and Polish Red cows (64.7%) was remarkably higher than that of the Black-and-White cows (39.9%).

The studies were carried out on black-and-white cattle of the Ural intra-breed type, bred at the enterprises of the Sverdlovsk region. The studied groups of animals are formed depending on the milking technology (milking in a milk pipe, in milking parlors, robotic milking). The level of hormones in the groups of cows, where intensive milking technologies were used, is higher than in the groups of linear milking in the milk pipeline: prolactin by 17.2 ng / ml; adrenocorticotropic hormone by 10.3 pg / ml; cortisol by 5.3 nmol / l. The number of heifers with a high type of stress tolerance is on average 6.3% less in groups where intensive milking technologies were used in comparison with linear milking in a milk pipe.

The age of cow use is of big importance for the practice of dairy farming, since earlier culling of cows leads to a lack of milk, and later culling leads to the decrease in genetic progress. The purpose of the researches was to determine the dynamics of milk productivity of cows of Black-and-White breed by lactations. The researches have been carried out in the OJSC Breeding Farm “Oktyabrsky” in the Ferzikovsky district in the Kaluga region, where cattle of Black-and-White breed are bred. The object of researches was the breeding stock of Black-and-White cattle that had been lactating for five lactations. It has been found that the increase in milk yield occurred from I to IV lactation. For example, first-calf heifers had 6154,9 kg of milk yield and were statistically significantly inferior to cows of II lactation by 242,8 kg (P < 0,001) or by 3,9 %. The superiority of cows of III lactation over first-calf heifers in milk yield was 466,2 kg (P < 0,001) or 7,6 %. The maximum differences in milk yield between first-calf heifers and cows IV lactation were 704,8 kg (P < 0,001) or 11,5 %. Cows of V lactation also significantly outperformed of fi rst-calf heifers in milk yield by 381,6 kg (P < 0,01) or 6,2 %, but their milk yield was lower than that of cows during III and IV lactation. It has been revealed in the course of research that cows of all the studied lactations were characterized by sufficiently high milk productivity for cattle of Black-and-White breed. There was the increase in milk yield with the age of animals. The increase in milk yields dynamically occurs till IV lactation, and then their decrease is observed.

A comparative analysis of productive, reproductive and technological traits of cows of Red Steppe and Black-and-White breeds has been carried out under the conditions of peasant farm “PF Ershov” in the Buguruslansky district in the Orenburg region. It has been established as a result of researches that heifers of Red Steppe breed have been effective inseminated by 0,4 months earlier and had live weight more by 18 kg or 3,6 % than herdmates of Black-and-White breed. Animals of Red Steppe breed had a slight advantage over Black-and-White breed in terms of milk yield and fat content. Cows of Red Steppe breed have a higher coeffi cient of lactation constancy. The advantage of cows of Red Steppe breed over Black-and-White first calves was 2,4 %. The advantage of mature lactation of Red Steppe cows over Black-and-White breed was only in the average daily milk yield by 1,2 kg or 5,1 %. Udder in animals of Black-and-White and Red Steppe breeds had a uniform development of the front and rear parts and in absolute terms (42,5–44,3 %) met the requirements of machine milking. In animals of Red Steppe breed the duration of the open days period was on average 12–28 days shorter depending on calving and corresponded to the indicators of highly productive cows. The coefficient of reproductive ability of first-calving cows of Red Steppe breed was 0,87, which is 0,05 higher than in Black-and-White cows; at the second calving – 0,88, which is 0,03 higher than Black-and-White herdmates. Thus, animals of Red Steppe breed on productive and reproductive traits have superiority over herdmates of Black-and-White breed that is explained by their adaptation to local conditions of feeding and housing.
