Introduction. When creating the Simmental beef breed of cattle during many years carried out researches to study the effectiveness of the use of meat Simmentals of foreign selection in crossbreeding with cows of Simmental breed of domestic selection. Were created the herds of the desirable type by breeding "in themselves" animals, that meet the requirements of the target standard, formed a genealogical structure. Now carry out the work with related groups of cattle of the created Simmental meat breed, which are the basis for the creation of further lines, but the growth and development of animals of different related groups have not been sufficiently studied. Therefore, the study problems of growth and development of repair heifers of different related groups has not only theoretical, but also practical importance. The purpose of our researches was to study the dynamics of linear growth and weight development of heifers of different related groups of the created Simmental meat breed. Research materials and methods. The researches was carried out on heifers of different related groups of the created Simmental meat breed in PJSC "Dniprovske" of Boryspil district of Kyiv region. To analyze the growth and development of heifers were formed groups of animals depending on their belongings to related groups of 15 heads in each: I Group – Metz 5290; II – Achilles 369; III – Abricot 58311; IV – Huxla 19223; V – Hercules 8942 and VI – Signal 120. Research results. It was determined, that heifers of the II group, which belong to the related group of Achilles 369, by live weight at all ages of periods surpass to peers. Thus, at 18 months of age the advantage of heifers of the II group by live weight in comparison with to peers of the I, III, IV, V and VI groups was 4.1; 3.0; 5.0; 14.1 and 11.4 kg. In heifers of related groups Hercules 8942 and Signal 120, the coefficients of variability of live weight at birth in which were the lowest, and in the following age periods they little changed, therefore at 18 months of age in these heifers they were the highest, comparison with analogues, and was to 8.4 and 9.2%, respectively. When studying the exterior of heifers of different related groups it was determined, that newborn heifers of the I group, which belong to the related group of Metz 5290, surpass their peers in height indicators. Their the height at the withers and the height at the sacrum were 74.0 and 79.1 cm, which is 0.6; 1.3; 2.1; 3.2 and 2.6 cm and is 0.3; 1.2; 2.9; 3.6 and 3.2 cm more than in analogues of the II, III, IV, V and VI groups, respectively. The best indicators of latitudinal measurements had the heifers of the III group, which belong to the related group Abricot 58311. In heifers of this group the width of the chest was 17.6 cm, width in the hip joints – 21.8 cm, width in the hips – 18.1 cm, and width in the ischial tubercles – 12.6 cm. The depth of the chest and the girth of the chest behind the shoulder blades were the highest in heifers of the I group, which belong to the related group of Metz 5290. They were 32.2 and 79.6 cm, respectively. When analyzing the measurements of heifers at 18 months of age, it was determined, that the height indicators had advantage by heifers of the II group, which belong to the related group of Achilles 369. Their, the height at the withers and height at the sacrum were 124.5 and 129.8 cm, which is 0.3; 1.3; 2.5; 5.3 and 4.2 cm and is 0.9; 2.2; 4.1; 6.6 and 5.9 cm more than in analogues of the I, III, IV, V and VI groups, respectively. The best indicators of latitudinal measurements had the heifers of the III group, which belong to the related group of Abricot 58311, since they had increases of measurements width of the chest, width in the hip joints, width in the hips and width in the ischial tubercles for the period from birth to 18 months of age the highest comparison with peers. Such indicators as depth of the chest and the girth of the chest behind the shoulder blades were highest in heifers of the II group, which belong to the related group of Achilles 369. Their increases of measurements depth of the chest and the girth of the chest behind the shoulder blades for the period from birth to 18 months of age also were highest comparison with peers and were 35.5 and 94.2 cm, respectively. Conclusions. It was determined, that the animals of the related group of Achilles 369 at all ages of periods had a large live weight in comparison with their analogues. The lowest coefficient of variability of live weight at 18 months of age was in heifers of the related group Abrikot 58311 and amounted to 6.5%. Heifers of the related group of Achilles 369 had the highest indicators of the following measurements: height at the withers (124.5 cm), height at the sacrum (129.8 cm), depth of the chest (67.4 cm), girth of chest behind the shoulder blades (173.1 cm) and oblique length of body (146.4 cm). The highest latitudinal measurements were observed in the heifers of the related group Abrikot 58311. Thus, the width of the chest was 49.9 cm, the width in the hip joints was 42.2 cm, the width in the hips was 43.3 cm, and the width in the ischial tubercles was 29.2 cm. Heifers of the related group Metz 5290 had the highest half-girth croup (110.2 cm) and girth of metacarpus (18.4 cm). In general, heifers of all groups showed good energy of growth and a typical for beef cattle exterior.

Introduction. Four domestic meat breeds of cattle have already been created – Ukrainian, Volynian, Polessian and Southern. Now carry out the work to create another breed of cattle, the Simmental meat, based on local Simmental combined direction of productivity. Now carry out the work with related groups of cattle of the created Simmental meat breed, which are the basis for the creation of further lines, but the economic and biological characteristics of animals of different related groups have not been sufficiently studied. This is especially touch of repair heifers, their raising. Therefore, the study problems of growth, development and biological characteristics in the raising of repair heifers of different related groups had is not only theoretical but also practical importance. The purpose of our researches was to study the dynamics of live weight and reproductive ability and their selection and genetic parameters of heifers and first-calf cows of different related groups of the created Simmental meat breed. Research materials and methods. The researches was carried out on heifers and first-calf cows of different related groups of the created Simmental meat breed in PJSC "Dniprovske" of Boryspil district of Kyiv region. To analyze the growth and reproductive ability of heifers and cows were formed groups of animals depending on from that to which related group they belong: I group – Metz 5290; II – Achilles 369; III – Abricot 58311; IV – Huxle 19223; V – Hercules 8942 and VI – Signal 120. Research results. We determine that heifers of the II group, which belong to the related group of Achilles 369, by live weight at all ages of periods surpass to peers. Thus, at 15 months of age, the advantage of heifers of the II group by live weight in comparison with peers of the I, III, IV, V and VI groups was 6.0; 1.2; 7.8; 17.3 (P > 0.90) and 12.8 kg. In heifers of related groups Hercules 8942 and Signal 120, the coefficient of variability of live weight at birth in which was the lowest, and in subsequent age periods it little varied, therefore at 15 months of age in these heifers it was the highest, in comparison with analogues, and was 9.8. When studying the age repeatability of live weight of heifers of different related groups, we determine, that in heifers of the related group of Signal 120 indicators of the coefficient of repeatability of live weight in all age periods were the highest and fluctuated from 0.75 to 0.95. The longest duration of service and between calving periods was in cows of the II group, which belong to the related group of Achilles 369, they were 155.3 and 435.5 days, respectively. The coefficient reproductive ability was highest in cows of the IV group, which belong to the related group of Huxle 19223, and was 0.92, and the lowest – in cows of the II group, which belong to the related group of Achilles 369 – 0.85. An important indicator of the reproductive ability of animals is the index of fertility. In our researches, it was determine that the animals of the experimental groups generally had average fertility. Thus, their index of fertility fluctuated from 40.8 (II and V groups) to 42.4 (IV group). When calculating the possible percent of calves on 100 cows, it was determine that the lowest this indicator was in cows of the II group, which belong to the related group of Achilles 369. They were inferior to animals of the I, III, IV, V and VI groups by 2.0; 1.7; 7.3; 2.2 and 4.0 goals. Also, the coefficients of variation of indicators of reproductive ability of heifers and first-calf cows of different related groups were calculated. It was determine, that the heifers of the related group Huxle 19223 had the highest coefficient of variability in the duration of the service period, which was 47.8. When calculating the correlation connexions between growth and reproductive ability of heifers of different related groups detected in all groups of animals a positive relationship between live weight at 7 months of age and index of fertility, between live weight at the first insemination and the age of the first insemination and between live weight at the first insemination and the age of the first calving. Conclusions. It was determined, that the animals of the related group of Achilles 369 at all ages of periods had a large live weight in comparison with their analogues. The highest coefficient of variability of live weight at 15 months of age was in heifers of the related group Signal 120 and amounted to 9.8. Also, the heifers of this group had the highest the indicators of the coefficient of recurrence of live weight in all age periods and ranged from 0.75 to 0.95. The best indicators of reproduction were characterized by animals of the related group Haxle 19223. The coefficient of reproductive ability in them was 0.92, and the index of fertility was 42.4. Also, heifers of the related group Haxle 19223 had a highest coefficient of variability in the duration of the service period, which was 47.8. In animals of all groups was revealed a positive relationship between the live weight at 7 months of age and the index of fertility, which indicates the possibility of using this relationship in breeding work with the herd.

One of the ways of increasing level of animal economically useful traits is selection work with farm families. In pedigree cattle breeding of Ukraine families are a statistical component of breed genealogy. Among the main scientific works on working with families, it should be noted minimum number of female ancestors, proposed by D. T. Vinnichuk, to determine the breeding value, different categories, classification and techniques for evaluating related groups of females. The aim of our research was to analyse importance of farm families for genealogical structure of the breed. The research was on basis of data of primary breeding records at the herd of Volyn Beef cattle of “Zorya” breeding farm, Kovel district, Volyn region. Akula 102, Galka 37 and Galka 1537 families belonging to Krasavchyk 3004 bloodline, Smorodyna 613, Korona 2382 and Visla 1016 families – Tsebryk 3888 bloodline, Kalyna 212, Verba 1536 and Garna 536 families – Yamb 3066 bloodlines, Kazka 433, Galka 421 and Bystra 1124 families – Buinyi 3042 bloodline, Rozetka 1313, Arfa 599 and Bulana 943 families – Sonnyi-Kaktus 3307-9828 bloodline, and Palma 275, Desna 870 and Veselka 444 families – Mudryi 9100 bloodline were characterized. Belonging to a bloodline was determined by the father's side of female ancestors. Structural units of families: branches, branching with identifying the best individuals on breeding traits were submitted to identify the best combinations and successful use of closely related breeding. Comparing assessment of related groups of females on the main breeding traits belonging to Krasavchyk 3004 bloodline, it was noted that the cows of Akula 102 family predominated in live weight at 5 years’ age, milk ability and economic use duration, whereas the cows of Galka 1537 family – on traits of reproductive ability. Smorodyna 613 family of Tsebryk 3888 bloodline had high duration of economic use and cows’ live weight at 5 years’ age compared with Korana 2382 and Visla 1016 families with equal values of the exterior traits (height measures) and coefficient of reproductive ability. The families of Mudryi 9100 bloodline in terms of reproduction (calving interval, coefficient of reproductive ability) had the highest figures of cows’ milk ability and live weight. The cows of Bulana 943 family had a considerable predominance over representatives of Rozetka 1313 and Arfa 599 families of Sonnyi-Kaktus 3307-9828 bloodline by main economically useful traits. High indices of reproductive ability were noted in these families. Heifers of the families of Buinyi 3042 bloodline had high live weight at 18 months’ age at average values of milk ability and cows’ live weight at 5 years’ age. More equal figures of growth rate, exterior and economic use duration were observed in the cows of Kalyna 212, Verba 1536 and Garna 536 families of Yamb 3066 bloodline. Breeding by families in beef cattle breeding is an important element of selection, because it allows to evaluate not only related group of female ancestor, but also to analyse a successful combination with lines and purposeful use of closely related breeding by the best representatives of a breed.

Two randomised-block experiments have been carried out to examine the relative feeding value of wheat and barley as supplements to grass silage for finishing beef cattle. In each experiment unwilted, formic acid-treated silage was offered ad libitum and supplemented with 500 g soyabean meal and 50 g minerals and vitamins to 44 twelve month old bulls for 157 and 172 days in experiments 1 and 2 respectively. In addition 12 animals received 2.5 kg rolled spring barley (LB), 12 received 4.0 kg barley (HB) and 20 received 3.25 kg rolled wheat (W). Silage was offered once daily and concentrates twice daily in two equal meals.Eleven British Friesian bulls and thirty-three bulls which were Friesian x Continental beef breed were used in each experiment. They were initially 402 and 385 kg live weight in experiments 1 and 2 respectively. In both experiments the animals were housed and fed in groups of four in slatted pens. All animals were slaughtered at the end of the experiments to obtain carcass data.

Breeding Farms

For the last years significant reduction of breeding farms has led to decrease in the number of populations and these trends are particularly concerning beef livestock, competitiveness of which is lower compared with dairy cattle-breeding. There is observed to decrease not only number of indigenous populations, which aren’t able to compete on productivity, but also native specialized cattle. So, population of Ukrainian Beef breed declined 1,5 times (8 breeding farms, 2733 head, 1135 cows on January 1, 2010 vs. 3, 1824, 665 respectively on January 1, 2016), Polessian Beef breed – 2,2 times (27 breeding farms, 8904 head, 3705 cows on January 1, 2010 vs. 10, 4113, 2157 respectively on January 1, 2016), Ukrainian Grey – 1,2 times (4 breeding farms, 1075 head, 437 cows on January 1, 2010 vs. 2, 903, 341 respectively on January 1, 2016).The reality of the recent years indicates that some native beef cattle breeds can be considered as local and as needing conservation in the nearest future. Thereby, the aim of our work was to study dynamics of growth, productivity and reproductive ability of breeding stock of Ukrainian Grey breed compared with Ukrainian Beef, Polessian Beef having been created with its participation, and Blonde d'Aquitaine – a foreign specialized beef breed being bred under the same conditions. Materials and methods.The investigations were carried out at the herds of SE «Polyvanivka» Research Farm», Magdalynivka district, Dnipropetrovsk region and AF «Klen», Zhovkva district, Lviv region at breeding females of Ukrainian Grey (n = 279), Blonde d'Aquitaine (n = 42), Ukrainian Beef (n = 159) and Polessian Beef (n = 100) breeds. The indicators of growth rate, reproduction, and productivity were analysed based on data of zootechnical primary account registered at breeding farms. Results of research. Comparison of averages by a group found that the Ukrainian Grey animals were characterized by slightly lower figures of live weight at all the investigated ages. Under the same growing conditions, live weight of the Ukrainian Grey animals at the age of weaning was 14 kg (P < 0,001) less compared with the Ukrainian specialized beef breed (Ukrainian Beef) and by 19 kg (P < 0,001) less compared with the French specialized beef cattle (Blonde d'Aquitaine). The results are quite predictable that the indigenous breed isn’t able to compete with specialized beef cattle. The Ukrainian Grey animals were characterized by lower figures of average daily gain of live weight almost for all the investigated age periods with the greatest difference from birth to weaning – 56 g (P < 0,001) compared with Ukrainian Beef and 79 g (P < 0,001) compared with Blonde d'Aquitaine. The Ukrainian Grey heifers at the age from 1 to 2 years were characterized by almost the same growth rate as Ukrainian Beef and Polessian Beef contemporaries and predominated slightly over Blonde d'Aquitaine. The greatest difference was observed between milk ability of the Ukrainian Grey and Polessian Beef cows within 15-21 kg (P < 0,001). Predominance of cows of other studied breeds over Ukrainian Grey was 13 kg (P < 0,001) after the 1st calving, 14-19 kg (P < 0,001) after the 2nd calving and 11-15 kg (P < 0,001) after the 3rd calving. Reliable differences in calving interval weren’t revealed between Ukrainian Grey and Ukrainian Beef, Blonde d'Aquitaine (except for calving interval between the 1st-2nd calving). Comparative analysis of age repeatability of live weight revealed that gradual reduction of repeatability coefficient with each distance from the age of 210 days or 1 year was characterized for the animals, kept in "Polyvanivka" breeding farm. So, the highest age repeatability was observed at adjacent periods – 210 days-1 year, 2-3 years. Higher levels of age repeatability of live weight were found at the Polessian Beef and Blonde d'Aquitaine animals. The results of research of Ukrainian Grey cows’ productivity should not be assessed pessimistically, because productivity for indigenous and local breeds has never been the main traits in their preservation. It is studied to monitor their state. Conclusions. So, indigenous Ukrainian Grey cattle are inferior to all the investigated beef breeds by productivity that caused by its triple-purpose specialization with working ability at the first place in the past. The significant high and middle levels of age repeatability indicate the possibility of effective selection of Polessian Beef and Blonde d'Aquitaine heifers on live weight at weaning (210 days), whereas for Ukrainian Grey and Ukrainian Beef animals at 1-years’ age. No reliable correlation of live weight with milk ability was found at the Ukrainian Grey, Polessian Beef, and Blonde d'Aquitaine cows and inverse correlation of live weight at 4-years’ age with milk ability after the 2nd calving – at the Ukrainian Beef cows.

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.

Conformation features of animals, which are the external expression of the constitution play an important role in breeding work they can be judged on the productivity of the animal and the general state of the organism. The data on live weight, measurements and body indices of young Red deer of Altai-Sayan breed in LLC “Niva” in the Altai Republic have been presented in the article. The purpose of the research was to identify the features of growth and development of young Red deer of Altai-Sayan breed. Two groups of 10 animals in each have been formed. In the 1st group were included males, in the 2nd – females from birth to 18 months of age, which have been kept under the same conditions of feeding and housing. Studies have shown the gain in live weight of young animals in the period from birth to one and a half years. At the end of the experiment males had a live weight of 168,5 kg and surpassed females by 20,4 kg. Data on the average daily, absolute and relative gains in the live weight of young Red deer have been also obtained. The absolute gain in live weight in males from birth to the end of the experiment was 152,0 kg, and in females it was 132,6 kg. The relative gain from birth to the age of 6 months was 136,50 % in males and 141,44 % in females, while from 12 to 18 months it decreased to 26,35 % in males and 30,23 % in females. Comparative analysis of measurements of the two groups has shown that males were taller and larger than female Red deer during the whole period of studies by 3–6 %.

The aim of our research was to conduct a retrospective analysis and to study the current state of the subjects breeding Znamensk intrabreed type of Polessian Beef breed and to assess main economically useful traits and genealogical structure. Material and methods. Research of productive and economic activity of breeding farms has been carried out based on the electronic database of State Register of Breeding Subjects in Livestock for 2003-2016. Analysis of the number of breeding animals, distribution of cows by age, animals’ live weight, milk (as a calf’s live weight at the age of 7 months) and reproductive abilities has been performed based on breeding account (form №7-myas) for 2010, 2012, 2014, 2016. Results of research. The most breeding farms meet the minimum requirements of the target standard of Znamensk intrabreed type on the main quantitative traits of animal productivity. "Kolos" АLLC, Kirovograd region and «Agrikor Holding" LLC, Chernihiv region were the most numerous. High realization of genetic potential of meat productivity (daily gain of live weight above 1000 g) was observed at animals in «Kolos» АLLC and «Sharivske» PE. There have been sold 222 head of the breeding youngsters for 13 years. The greatest number of animals was observed according to annual reports in 2012. It can be explained by the number of subjects conducting the selection and breeding work with the intrabreed type. The share of cows did not exceed 43.0% (2012), bull – 1.5% (2010), calves of different gender and age groups – 66.1% (2014). 85.5% of all the available breeding stock (5369 head) was approved and 67.8% corresponded to elite and elite-record classes. Live weight of the approved cows has increased by 7.5% at the age of 3 years, 9.7% at the age of 4 years and 11.1% at the age of 5 years since 2010. Differential for live weight of cows at the age of 4 and 5 years was 9 and 11 kg on the average. There was adequate number of animals, live weight of which was in a wide range, that is from 551 kg and above. So, such cows were 111 head in 2010 and 234 head in 2016. These cows realise genetic makings of high productivity sufficiently and they are material for selecting the best representatives of Znamensk intrabreed type. Gradual increase of milk ability was noted from 2010 till 2016 after the first calving by 13.7%, the second – 12.2, the third – 11.7, and by 11.9% on average. Differential for milk ability of cows was 5 kg (2010, 2012), 11 kg (2014) and 2 kg (2016) on average. Average calving interval of cows for the period are oscillatory in nature and didn’t exceed 420 days during 2010-2014. Gradual increase of age at first calving of heifers by 101 days was observed from 2010 to 2014 with reduction to 824 days for next two years. It should be noted violation of course of cows’ and heifers’ calvings, it was 29 and 36 cases in 2010 and 2012 respectively, whereas in subsequent periods, these values were significantly lower or non-existent. It may indicate a high level of veterinary services and compliance of technologies of feeding and management. Efficiency of beef cattle-breeding depends on the growing of calves. Analysis of the results shows that live weight of calves at the age of 210 days has increased in each investigational year. The values are oscillatory in nature between 8 and 15 months. Sexual dimorphism was confirmed and proven – bull-calves had higher growth rate compared to heifers. Significant reduction in the livestock number of the approved bloodlines and their absence in some cases (Radyst 113 and Darovanyi 400) was observed. This is due to the increased share of Polessian Beef and Charolais bulls used for reproduction. There were 139 cows, 27 heifers and 13 calves in group belonging to Polessian Beef and Charolais bloodlines in 2012, whereas in 2014, 281, 193 and 18 respectively, representing 81% of the total population. Conclusions. The research revealed that livestock of the type were concentrated in «Agrikor Holding» breeding farm, Pryluky district, Chernihiv region with a total of 922 head, including 348 cows. Productivity of animals by the valuation results at the beginning of 2016 (live weight, milk ability, reproduction) significantly increased. Current genealogical structure of Znamensk intrabreed type was represented by bulls belonging to Polessian Beef and Charolais bloodlines, share of which was 81%.

The results of the crossing of the Kalmyk cows with the Galloway   bulls are presented. The indicators of growth and development in crossbred bulls in comparison with purebred from birth to 8 months of age were studied. It has been proven that the crossing of Kalmyk cows with Galloway bulls in the conditions of the Saratov Trans-Volga region is an effective breeding method for increasing the efficiency of the beef cattle industry. Half-blooded bulls of Galloway breed compared to the pure-bred Kalmyk at 8 months of age had a large live weight of 36.9 kg or 17.4%. And also characterized by the best development of articles physique. In terms of the depth of the chest, the excess was 5.95 cm or 12%, the width of the chest behind the shoulder blades was 6.03 cm or 20%, and the oblique length of the body was 5.9 cm or 5%. In general, the crossbred animals possessed the best meat forms and ratios of physique articles.

Relevance. According to the results of numerous scientific and laboratory studies, both lack of fatness and excessive obesity of livestock reduce the quality of meat and are the result of imperfect technology of growing and fattening animals or a low level of breeding and irrational use of feed.Methods. Scientific and production experiments were carried out in the Tau Samal LTD Company LLP and the Plemzavod Almaty SEC Almaty region. The dynamics of live weight, fattening and slaughter qualities of young dairy and dairy and beef cattle during the periods of growing and fattening were studied.Results. Gobies of experimental groups of different genotypes, which received feed additives in addition to the main diet, in terms of live weight, fattening qualities, growth and development rates, total and average daily gains, morphological and chemical compositions and energy value of meat favorably differed from uniform age counterparts from the control groups.
