In dairy cattle breeding, selection and breeding work is widely used in order to transfer the pedigree qualities of parents to the offspring and obtain highly productive young animals. In this regard, in the conditions of «Enbek» LLP in the Akmola region, the growth and development of young Simmental breed depending on the origin was studied. Live weight of Litera line young animals at birth was 33.4 kg, at the age of 6 months-174.9, 12 months-251.8, 18 months-387.1 kg, respectively, Wildfang bull 32.0 kg, 165.5 kg, 251.3 kg, 378.6 kg. The average daily gain between the ages of birth and 6 months was increased. With age, the body parameters, height at the withers, increased from 104.3 cm and 103.5 cm to 125.4 cm and 123.9 cm, respectively, from 6 months to 18 months of young animals. According to the physique indices, we can say that the young Simmental breed is balanced. Only some deviations of the leggy index are observed from the optimal indicators. The index of legginess decreases with age by 7.7%, with indicators of 6 months – by 57%, at the age of 18 months-by 49.3%. The extension index for the period from 6 to 18 months increased by 10.5%, respectively, for 6 months-by 103.3%, for 18 months-by 113.8%. With age and an increase in live weight, the body of young animals lengthens, its width increases, the animal becomes deeper and relatively long-legged. Depending on the origin, we suggest using the Litera bull line, taking into account the growth and development of young animals, and the productivity indicators of bulls.

One of the ways to increase meat resources is to improve the condition of livestock on farms in the Russian Federation. This is due to the fact that when the fatness of the animal increases, the meat yield in the carcass increases. The purpose of the researches was to establish the features of the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed. In order to achieve this purpose two groups of steers-analogs of Hereford breed (control and experimental) at the age of 6 months per 10 head in each have been formed. The time of the experiment was: the preparatory period of 22 days and the main one 275 days. Steers of the control group have received the main farm ration, and steers of the experimental group have received the main ration and feed protein additive Biovitel for 30 days with 10-days interval at the dose of 100 g per head during the sixth month. The results of researches on the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed have been refl ected in the article. The addition of the feed additive Biovitel to the main ration of the experimental group of steers helped them to achieve a higher live weight and higher average daily gains under the same environments of feeding and housing in all age periods. By the end of the experiment (15 months) the experimental group of steers have reached the live weight of 430,2 kg, which was higher by 19,9 kg or 4,9 % compared to the control group of steers. In order to improve the quality of beef and increase its production more intensive rearing of steers of Hereford breed with the use of feed protein additive Biovitel has been justifi ed. The recommended dose is 100 g per head. This dosage allows you to achieve the average daily gain of 967,5 g and the average live weight of 430,2 kg by 15 months of age, reduce the prime cost and increase the profi tability of beef production.

Изучены рост и развитие телок помесей горского скота с русской комолой породой в горной зоне Республики Дагестан. Доказана эффективность использования высокогорных пастбищ крупным рогатым скотом. Установлено, что молодняк помесных животных по сравнению с аборигенным скотом имеет более высокую живую массу при рождении на 1,2 кг, или на 6,9. При отъеме в 8месячном возрасте помесные телки имели живую массу 156 кг против 140 кг у аборигенного горского молодняка, что на 16 кг, или 11,4 больше. В 12, 15 и 18месячном возрасте живая масса помесных телок составляла 220,2 кг, 267 и 321,4 кг, соответственно, или на 27,1 кг, 36,4 и 45,1 кг больше по сравнению с горским скотом. Среднесуточные приросты помесного молодняка в среднем за период выращивания телок составили 556 г против 475 г, то есть они были выше на 17 по сравнению с горскими аборигенными телками. Промеры статей телосложения животных тоже были в пользу помесных. Высота в холке у помесей достигала в возрасте 8 мес 85,3 см, в 12 106,5 и в 18 мес 110,5 см, а у аборигенных телок горского скота высота в холке была значительно ниже по сравнению с помесями и составляла 79,8 см, 93,4 и 103,8 см, соответственно. В 18месячном возрасте телки горского скота уступали по высоте в холке помесям на 6,7 см, или на 6,4. Исследования свидетельствуют об эффективном использовании высокогорных пастбищ Дагестана помесным скотом. Такой подход к ведению мясного скотоводства в условиях горной зоны Республики Дагестан позволит увеличить производство дешевой и высококачественной говядины.Growth and development of hill cattle heifers and their cross breeds with Polled Russian breed are researched. Efficiency of utilizing mountain grass is proved. It is ascertained that cross breed young stock live weight at birth exceeds that of native ones by 1,2 kg or 6,9. Cross breed heifers at ablactation had live weight of 156 kg at 8month age versus 140 kg of native ones, which is 16 kg or 11,4 higher. Live weight of 12, 15, and 18month cross breed heifers was 220,2 kg, 267 kg, and 321,4 kg, respectively, which is 27,1 kg, 36,4 kg, and 45,1 kg greater in comparison with mountain cattle. Average daily gain of cross breed animals was 556 g versus 475 g, which is 81 g or 17 higher in comparison with mountain heifers. Shoulder height of cross breed heifers was at the age of 8 months 85,3 cm, 12 months 106,5 cm, and 18 months 110,5 cm, while mountain cattle height was sufficiently lower in comparison with cross breeds and was 79,8 cm, 93,4 cm, and 103,8 cm, respectively. At the age of 18 months mountain heifers were inferior to cross breeds by 6,7 cm of shoulder height, which is 6,4. The study reveals high efficiency of utilizing Dagestan mountain grass by cross breed cattle. Such approach to beef cattle farming provides for increase of cheap and high quality beef production.

The article provides data on the weight growth of bulls of different types of productivity. The growth and development of Black-and-white, Simmental and Aberdeen-Angus bulls were studied during the period of their rearing and feeding. The change in live weight was established, the dynamics and growth rate of the studied bulls were calculated depending on the breed and type of productivity. The research results showed that the Aberdeen-Angus bulls had the highest live weight during fattening - 485.2 kg, which was significantly higher than that of the Black-and-White and Simmental breeds by 68.7 kg (p <0.001) or 14.0% and 19.7 kg (p <0.01), or 4.1% respectively. The average daily gain in live weight from birth to 15 months of age in bulls of Black-and-white, Simmental and Aberdeen Angus breeds amounted to 860.0; 965.1 and 1022.7 grams respectively. In the Aberdeen-Angus cattle, in comparison with the Black-and- White and Simmental breeds, the value of this indicator was significantly higher, by 162.7 g, or 15.9% (p <0.001) and 57,6 g, or 5.6% (p <0.01) respectively. It was found that the type of productivity had a certain effect on the dynamics of live weight, the intensity of growth and development of animals.

The results of the assessment of replacement heifers of the dairy period of growing the Ukrainian black-and-white dairy breed according to the intensity of growth and development with various methods of keeping are presented.The young of the control group were raised according to the traditional technology in the calf room in Evers cages, the experimental group - "cold" method. Live weight of animals was determined on the basis of monthly weighing data during their rearing. Live weight and growth intensity in the lactation period were the highest in the group of calves during "cold" rearing. Live weight at 3 months of age - 101.8-105.2 kg, at 6 months - 171.3-178.3 kg. It was found that in terms of live weight at 6 months of age, cold-fed animals were better by 7.0 kg, or 4.1%, animals of the first group increased their live weight by 5.24 times, the second - by 5.37 times . The average daily gain of repair young in the second group was higher by 36 g compared to keeping calves indoors. No significant differences in the linear measurements of heifers of both groups under 3 months of age were detected, the differences began to appear from the third month until the end of the lactation period. Heifers raised in the "cold" way, with a larger live weight had, accordingly, larger basic measurements. The proportions of the physique of heifers changed with age. Indices of stretching and massiveness increase with age, bony, long-legged, pelvic, beaten - decreases. There were animals for "cold" keeping. Indices of physique (stretch, long-legged, beaten, massive pelvic, thoracic) at the end of the milk period show that heifers in the "cold" content exceeded their peers grown indoors prophylaxis. Key words: calves, live weight, average daily gain, measurements, body mass indices, traditional and cold way of keeping.

Growth and development, the basic sensory and technological properties of purebred sheepskins and local young growth sheep were estimated. Animals are received from industrial crossing of ewes of Romanov breed and rams-breeders of Ghissar. The dynamics of changes in live weight indicators, absolute, relative, average daily gains, and also technological properties of sheepskins, especially depending on the age of Romanov young animals, was established, a comparative assessment of these characteristics with local peers was performed. At birth and in the period of postnatal ontogenesis, crossbreeds dominate over purebred young animals in terms of live weight ‒ 31.8 %, with 10.8 growth rate. The live weight of crossbreeds was 28.8 % before weaning, and the absolute and average daily gain was 31.6 % more than of purebred peers ones. The maximum level of intensive growth of young animals is observed up to the age of 4 months. A wavy process is observed by terms of absolute/relative/average daily indicators. That depends on the milk yield of ewes. At the time of Romanov young sheep slaughter, ones had a thick coat of wool, without signs of molting and shedding from light gray to dark gray. Local peers had a coarser wool cover, and were characterized as a strong development of layers of the ectodermis and fit the requirements of the procurement standard raw materials. The weight of freshly obtained materials from young animals dynamically increases in proportion to live weight by 29.9-50.3 % with age. In terms of the area of raw materials, an intensive increase is observed from age of 4 to 8 months (+ 21.9 %), and from 8 to 12 months (+24.5 %), with the advantage of local young 9.8 %, weight at 10.9 %.

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.

Abstract Background Average daily gain (ADG) and lean meat percentage (LMP) are the main production performance indicators of pigs. Nevertheless, the genetic architecture of ADG and LMP is still elusive. Here, we conducted genome-wide association studies (GWAS) and meta-analysis for ADG and LMP in 3770 American and 2090 Canadian Duroc pigs. Results In the American Duroc pigs, one novel pleiotropic quantitative trait locus (QTL) on Sus scrofa chromosome 1 (SSC1) was identified to be associated with ADG and LMP, which spans 2.53 Mb (from 159.66 to 162.19 Mb). In the Canadian Duroc pigs, two novel QTLs on SSC1 were detected for LMP, which were situated in 3.86 Mb (from 157.99 to 161.85 Mb) and 555 kb (from 37.63 to 38.19 Mb) regions. The meta-analysis identified ten and 20 additional SNPs for ADG and LMP, respectively. Finally, four genes (PHLPP1, STC1, DYRK1B, and PIK3C2A) were detected to be associated with ADG and/or LMP. Further bioinformatics analysis showed that the candidate genes for ADG are mainly involved in bone growth and development, whereas the candidate genes for LMP mainly participated in adipose tissue and muscle tissue growth and development. Conclusions We performed GWAS and meta-analysis for ADG and LMP based on a large sample size consisting of two Duroc pig populations. One pleiotropic QTL that shared a 2.19 Mb haplotype block from 159.66 to 161.85 Mb on SSC1 was found to affect ADG and LMP in the two Duroc pig populations. Furthermore, the combination of single-population and meta-analysis of GWAS improved the efficiency of detecting additional SNPs for the analyzed traits. Our results provide new insights into the genetic architecture of ADG and LMP traits in pigs. Moreover, some significant SNPs associated with ADG and/or LMP in this study may be useful for marker-assisted selection in pig breeding.
