Depending on the characteristics of mothers feeding, the results of assessing the morphological composition of blood and some hematological parameters, trace element composition of blood and the dynamics of the average daily gain in live weight of calves are considered. In the Atninsky municipal district of the Republic of Tatarstan in the agricultural production complex “Plemzavod named after Lenin ”conducted a research and production experiment on Holstein cows (30 heads), as well as on calves that were received from them. All laboratory studies were carried out in the department of agrobiological research of the Tatar Scientific Research Institute of Agricwlture, FRC KazSC RAS. It was revealed that the content of leukocytes on the 60th day in calves of group II was significantly (p <0.05) lower than in control animals by 41.31%. On the 90th day, the hemoglobin concentration in individuals of the control and III groups significantly increased by 27.05% (p <0.001) and 29.69% (p <0.01), respectively. On the 60th day, the concentration of cobalt in individuals of group III was significantly (p <0.01) higher than in animals of group II by 7.94%. A significant increase in zinc concentration on the 90th day was found in individuals of the experimental groups - by 30.04 (p <0.01) and 19.56% (p <0.001), respectively, and manganese - for calves in the control %, p <0.01). Evaluation of the average daily gain showed the presence of a trend of its superiority in individuals of group III over the rest by 17.96 and 7.44% compared with animals of groups I and II, respectively.

The purpose of the work was a comprehensive evaluation of the productive and reproductive traits of sows of Yorkshire and Landrace breeds and their offspring under the conditions of a breeding enterprise in the Republic of Belarus. During the studies of reproductive traits, it has been revealed that the highest rate of prolificacy among the evaluated breeds was distinguished by Yorkshire sows 14,0 heads for farrowing. In terms of milk content, Landrace sows were 2,5 kg or 4,57 % higher than Yorkshire sows. In terms of weight and socket weight per piglet at weaning at the age of 28 days sows Landrace piglets surpassed herdmates Yorkshire breed in the weight of the litter by 6,8 %, and the weight of one pig by 0,9 %. It has been found by the results of the evaluation of fattening and meat qualities of purebred young pigs that the best parameters were different gilts of Landrace breeds, whose age achieve the live weight of 100 kg was 163,1 days, and average daily gain of live weight – 864,8 g, which was higher than in young pigs of Yorkshire breed by 1,8 day or 1,09 %, and 28,9 g or by 3,46 %. The young pigs of Landrace breed has been characterized by the best values of the area of the “eye of loin” – 73,8 cm² and the highest yield and amount of meat – 68,5 % and 24 kg, which was 11,4 cm² or 18,2 % and 0,4 kg or 3,5 abs.%, respectively, higher than the herdmates of Yorkshire breed. The results obtained indicate the possibility of using boars and sows of Landrace and Yorkshire breeds not only in breeding, but also in industrial pig breeding.

At the present stage of economic development of the Republic of Kazakhstan dairy cattle breeding should be competitive, highly productive and cost-effective, which contributes to ensuring the country’s independence from imports of dairy products. The formation of milk productivity of future cows begins with the preparation of cows for calving and the purposeful rearing of replacement young cattle, based on the achievements of scientific and technical progress, a systematic approach to the production of high-quality products. The researches have been carried out in the farm “Tauelsizdik” in the Eskeldinsky district in the Almaty region in the Republic of Kazakhstan. According to the results of the research, the average daily gain of live weight in 3 months of the post-embryonic period was 458,9±71,9 g in heifers have reared in narrow-sized pens, and 682,2±44,6 g in heifers have reared in group pens. At 3 months of age the live weight of heifers at rearing in narrow-sized pens has reached 76,5±2,5 kg in narrow-sized pens, and 98,3±1,7 kg in group pens (P < 0,001). The data of the experiment have convincingly shown the effectiveness of rearing heifers in group pens. The live weight of heifers at birth was 36,4±1,1 kg, at one month of age – 54,2±1,6 kg, at 2 months of age the live weight increased to 70,2±2,1 kg, at 3 months of age to 87,4±3,3 kg, at 4 months of age to 116,8±3,5 kg, at 5 months of age to 132,7±4,2 kg and at 6 months of age to 157,4±4,6 kg. The indices of lengthiness, chest, hip-chest and blockiness increased up with age, while the indices of high-leg and overgrown decreased down. For example, the lengthiness index has increased with age from 90 to 97 %, the chest index from 62 to 70, and the high-leg index has decreased from 59 to 54, overgrowth from 109 to 108 %.

The results of changes in the biochemical parameters of blood serum and live weight of calves when feeding dry cows with various diets are presented. The experiment was carried out on 30 cows of the Holstein breed and calves obtained from them, contained in the agricultural factory “Plemzavod im. Lenin» Atninsky municipal district of the Republic of Tatarstan. Laboratory studies were performed at the Tatar Scientific Research Institute of Agriculture, FRC Kazan Scientific Center, Russian Academy of Sciences. It was found that the use of experimental premixes in the diet of dry cows in combination with propylene glycol during the dry period promotes the birth of young animals with a greater live weight (28.54 ... 28.63 kg) compared to control animals and allows them to maintain higher growth rates further (gross increase of 58.31 ... 62.41%). In animals of the indicated groups, by the 90th day of life, the content of urea nitrogen in blood serum increases significantly (in individuals of group II by 44.16% (p <0.05)), triglycerides (in animals of group III by 183.33% (p <0.05)), total calcium (in calves of group II, the content of the studied parameter was significantly higher than in animals of group III by 18.75% (p <0.05)), aspartate aminotransferase (in animals of group II by 29.08 % (p <0.01)), and in animals of the control group - only albumin (by 24.55% (p <0.05). On the 60th day of life, individuals of group III have significantly higher than control animals total protein and alanine aminotronsferase in blood serum, and on the 90th day of life, calves of group II are characterized by a significantly higher content of total calcium, compared with individuals of group III.

Numerous studies have shown that animals with the same genetic potential can differ in productiveness. In this regard, specialists in this industry, when predicting the milk productivity of adult animals in the process of raising young cattle, divide rearing into separate periods. In order to study the conditions for growing dairy calves, a comparative analysis of the conditions for keeping and feeding calves in two farms of the Republic of Tyva was carried out. The conditions of growing calves in the dairy period in the conditions of different farms with the same breed composition of cattle were studied. A comparative analysis of the influence of the composition and level of the diet on the growth of young animals is given. Calves of both groups by birth weight at birth did not have significant differences: they were 0.05-0.07 kg. In dairy farms MUP “KaaKhemsky” and “OOO Turanskoye” young cattle from birth to 6 months are kept in separate rooms. There are no significant differences in the calf feeding schedule. In the Municipal Unitary Enterprise “Kaa-Khemsky” feeding with haylage of young animals is introduced from two months of age; at the farm of “OOO Turanskoye” silage has been given to calves from 4 months. However, from 4 months to six months of age, they showed a significant difference in the increase in live weight. At 4 months, the difference averaged 4.27 kg, at 5 and 6 months – 6.39 and 8.59 kg, respectively. As a result of the studies, it was concluded that a decrease in the drinking of whole milk and the introduction of a substitute at its early, three-month-old age, which are compensated by a large intake of hay, feed and silage, do not provide a high average daily gain in live weight of the growing organism of young cattle.

The article presents the data obtained as a result of carrying by employees of the Research Institute of sheep and goat breeding, a branch of the FSBSI "North Caucasus FARC", the scientific and economic experience to study the efficiency of a new fodder additive "Organic" on the productive and physiological indices of bull-calves during the completion of growing in the conditions of the farm "Pata" agricultural enterprise in the Karachay-Cherkessia Republic. The statement of the experience and all researches were carried out according to generally accepted methods. In the course of the experiment, the following indices were studied: the chemical compound of forages, the dynamics of a live weight gain in the experimental stock, hematological parameters, control slaughter data, economic indices. Completed researches have shown positive result from the use of the fodder additive "Organic" in bull-calves diets: an increase in the average daily gain of live weight by 25%, a slaughter yield by 1% and a high level of profitability – 27%. Thus, the additional introduction of "Organic" in a diet of young horned cattle in the 2nd experimental group promoted more intensive metabolism, stabilization of a physiological state, increase in productivity and, as a consequence, profitability of beef production. Researches in this direction reveal the latent fodder reserves promoting increase in the productivity of agricultural animals.

The most perspective genotype in our region is Red White-belted breed, which has high performance both under pure breeding and under crossing with other breeds. The results of complex evaluation of Red White-belted swine of the herd bred in SE "RF Zoryane" breeding farm are presented. It was revealed that animals of the farm comply with elite class and the first class. The main breeding boars used at the farm belong to such genealogical lines: Deviz, Division, Dantist, Debut, and Dobryak. In the structure of the herd, the most numerous was Dobryak line, which part was 58.8%, Division, Debut, Devis lines – 11.8% per line, Dantist line – 5.8%. The herd sows belong to 7 families: Drabowka, Dekada, Dyktsiya, Doina, Dylema, Delta, Dogma. Average prolificacy of the sows was 10.0 piglets. Litter weight at 60 days’ age was 181.0 kg, and live weight of piglet – 19.0 kg. The performance of sows as prolificacy increased by 0.6 head on average. The complex appraisal index for the herd was 104.1 points. The average daily gain of the replacement pigs was 570 g. The highest daily gain was from five to six months – 611.2 g, and the figure of compactness index characterized a certain elongation of animals, increasing meat traits. Further work with Red White-belted breed aims at preserving and expanding the breeding base and genealogical structure, as well as increasing the reproductive, fattening and meat traits.

The aim of this study was to evaluate the effect of zinc (Zn) supplementation in different commercial forms on the growth performance, health status, and Zn balance of weaners in field conditions. The animals were fed pre-starter (from the 28th to 47th day of life) and starter (from the 48th to 74th day of life) mixtures differing in Zn form and concentration. Group I was given ZnSO4 at 150 mg kg−1; Group II received pre-starter zinc oxide (ZnO) at 3000 mg kg−1 and starter at 150 mg kg−1; and Group III was given 150 mg kg−1 of zinc oxide nanoparticles (nZnO). We found that the average daily gain in Group I was significantly lower, compared to Groups II and III. A commonly accepted level of Zn (150 mg kg−1) as nZnO can be recommended, instead of therapeutic doses of Zn preparations with the same efficiency. Moreover, a lower level of Zn in the diet can prevent the excessive accumulation of this element in waste and, thus, reduce environmental damage.

AbstractA total of 384 piglets from a three-way cross Yorkshire ♂ × (Finnish Landrace ♂ × Dutch Landrace♀) ♀ in the live-weight range of 11 to 25 kg were used in a feeding trial. The effect of supplementary microbial phytase from Aspergillus niger var. Van Tieghem on performance (average daily gain (ADG), average daily food intake (ADFI) and food conversion ratio (FCR)) and apparent digestibility of total phosphorus (P), in comparison with a non-supplemented basal diet or a diet supplemented with one or two levels of monocalcium phosphate (MCP), were studied.The piglets were allotted to 12 blocks. Within each block, four experimental diets were offered ad libitum for a period of 4 weeks i.e. (1) basal diet; (2) basal diet + 1·0 g P, from MCP per kg diet; (3) basal diet + 1·9 g P, from MCP per kg diet; and (4) basal diet + 1450 phytase units (PTU) per kg diet. The diets, with added chromium III oxide as a marker, were cold pelleted without steam at a temperature not above 60°C to avoid a possible inactivation of the phytase. In all diets the ratio calcium: digestible P was intended to be constant.Adding 1450 PTU of Aspergillus niger phytase enhanced the apparent digestibility of P by proportionately 0·216 when compared with diet 1 and by proportionately 0·100 compared with diet 3. In addition, significantly higher ADG and ADFI and better FCR were noted in pigs receiving supplementary microbial phytase than in pigs on any other treatment. The content of digestible P of the diet with added phytase, however, zvas between the two levels of the diets with added MCP.

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.

Background: Choline is a nutrient with numerous metabolic functions, but its requirements for ruminants are unknown. The supplementation with bypass choline could enhance productivity. Methods: Twenty-four male lambs (Rambouillet 23.5 kg±3.17 kg initial BW) were fed a basal diet with treatments which consisted of a control and oral doses of ruminally-protected choline (4 g/d RPC) and plant-based choline (4 g/d Biocholine) in a completely randomized design with initial weight as a covariate. The experiment was conducted for 42 days during which live weight, dry matter intake, carcass characteristics, blood metabolites and basic hemograms were measured. Result: The daily gain in lambs was similar between treatments. Intake was higher in lambs given Biocholine (1.32 kg/d). The L* (represents the light to dark color) value and mineral content in the meat were improved with both sources of choline. Blood triglycerides increased by RPC compared with the other treatments and cholesterol was reduced by Biocholine. Alanine transaminase (ALT) and aspartate aminotransferase (AST) activity decreased by effect of choline. Hematological parameters were affected by choline supplementation regardless of the source; erythrocyte, monocytes and lymphocytes count decreased with both sources of choline in growing lambs.
