Приведены результаты изучения роста, мясной продуктивности и качества говядины, полученной от молодняка русской комолой (I группа), казахской белоголовой (II группа) и калмыцкой (III группа) пород. Установлено, что при постановке на опытв 8-месячном возрасте животные II подопытной группы превосходили по живой массе сверстников I и III групп, соответственно, на 4,1 кг и 23,9 кг, в 17 мес — на 16,2 кг и 49,8 кг.Бычки I группы превосходили по живой массе сверстников III группы в возрасте 8 мес на 19,8 кг, в 17 мес— на 33,6 кг. По результатам контрольного убоя бычки казахской белоголовой породы превосходили сверстников I и III групп по массе туш на 6,88 кг, или 2,7% (Р<0,05) и 35,81 кг, или 14,0% (Р<0,001). Убойный выход был более высоким у животных русской комолой породы (I группа). Их превосходство по этому показателю над сверстниками II и III групп составило1,07 и 2,29%. На основании результатов обвалки установлено, что выход мякоти в тушах бычков I группы был выше, чем у сверстников II и III групп — на 0,77 и 2,00%. Индекс мясности у бычков I группы в сравнении со сверстниками был выше на 0,24 и 0,70. Выход мякоти в тушах на 100 кг живой массы у бычков I группы был также превышал данный показатель у сверстников на 1,09 кг, или 2,44% и на 2,52 кг, или 5,83%. Наиболее ценных отрубов было получено больше от бычков I группы (русская комолая) по сравнению со сверстниками II и III групп. Установлена положительная корреляционная связь между живой массой бычков в начале и конце откорма с общим белком в сыворотке крови — в I группе 0,54—0,64, во II — 0,50—0,67, в III группе — 0,67—0,69; убойной массой и общим белком в сыворотке крови — в I группе она составила 0,47—0,50, во II — 0,49—0,51, в III группе — 0,51—0,53.The results of the study of growth, meat productivity and quality of beef obtained from young stock by Russian comola (I group), Kazakh white-headed (II group) and Kalmyk (III group) breeds are presented. It was established that when setting up the experiment at 8 months of age animals II experimental groups surpassed live weight of their peers I and III groups, respectively, by 4.1 kg and 23.9 kg, at 17 months - by 16.2 kg and 49.8 kg. Gobies of group I exceeded in live weight of their peers of group III at the age of 8 months by 19.8 kg, at 17 months - by 33.6 kg. According to the results of the control slaughter, Kazakh white-headed breed bullies exceeded their peers of groups I and III by carcass weight by 6.88 kg, or 2.7% (P <0.05) and 35.81 kg, or 14.0% (P <0.001). Slaughter yield was higher in animals of the Russian comola breed (I group). Their superiority over this indicator over their peers of groups II and III was 1.07 and 2.29%. Based on the results of deboning, it was found that the pulp yield in bull carcasses of group I was higher than that of peers of groups II and III — by 0.77 and 2.00%. The index of meatiness in bulls of group I in comparison with peers was higher by 0.24 and 0.70. The yield of pulp in carcasses per 100 kg of live weight in the first group of bulls I was also higher than that of their peers by 1.09 kg, or 2.44% and 2.52 kg, or 5.83%. The yield of the most valuable cuts was higher in bulls of Group I (Russian comola) compared with peers of Groups II and III. In the process of research, a positive correlation was established between the body weight of animals at the beginning and end of fattening with the total protein in the blood serum in group I; it was 0.54—0.64; in II — 0.50—0.67; in group III — 0.67—0.69, between the slaughter mass with total serum protein in group I it was 0.47—0.50; in II — 0.49—0.51; in group III — 0.51—0.53.

The purpose of research is increase of beef productivity and beef quality of Simmental calves at introduc-tion in a diet of feeding different doses of the drug Vetosporin suspension. Of the half-yearly animals, 40 males were selected and formed into group IV for the experiment. The differences were only in feeding. The young were fed the studied additive Vetosporin suspension. In this case, the supplement was an addi-tion to the basic diet of animals of the experimental II-IV groups. The volume of the additive added was 0.1; 1.0; and 2 ml per 10 kg of live weight, respectively. Control group I, consumed exclusively a diet that does not contain an additive. Based on the results of the experiment at the age of 18 months. The prevalence of bulls of the experimental live weight over peers was observed, which was 4.4-25.3 kg (0.78-4.67%). The study of the studied indicators after control slaughter in the context of groups showed the superiority of bulls of experimental groups in all the periods studied. It is established that at the age of 15 months. The size of the removable live weight of the youngest of the control group was less by 8.0-19.7 kg (1.75-4.29%) than in the animals of the test groups. In this case, the leading position was occupied by the youngest of group III, the prevalence of which was 0.7-11.7 (0.14 -2.51%). It should be noted that after 3 months a simi-lar picture of the distribution of the studied quantities was observed. As for the output of carcass, we can note the following. Outsider among the animals of the experimental groups was the control group. So the bulls of group I were inferior to those who received the additive by 0.7-1.3%. At 18 months, as well as at 15 months, the dominant position was occupied by gobies of experimental groups. It should be noted that among the animals of the experimental groups the leading place was occupied by the bulls receiving the feed additive in a dose of 1.0 ml per 10 kg of live weight, that is, the youngest of the III group.

One of the most effective ways of removing HM salts that have entered the digestive tract of fattened animals is the technological method of including adsorbent preparations in their diets, which, binding various toxins, excrete them from the body. The study purpose is to develop a method to increase the meat productivity and quality of meat of young cattle for fattening in a technogenic zone by inclusion of ToxySorb adsorbent in their diets with a high content of heavy metal salts in the amount of 1.25 kg/t of compound feed and lecithin in the amount of 10 g/100 kg of live weight. According to study results, it was shown that when these drugs were fed together in the indicated quantities, it contributed to better detoxification of xenobiotics. The calf bulls of experimental group 3 had the best slaughter indicators, as well as the best consumer, sanitary and hygienic properties of meat products.

Проведен анализ качественных характеристик мясной продуктивности бычков абердин ангусской породы в зависимости от типов телосложения. Научно-хозяйственный опыт проводился в одном из хозяйств Карачаево-Черкесской Республики в 2020—2021 годах. Из потомства быков крупного (I группа) и мелкого типа (II группа) абердин ангусской породы было сформировано 2 группы по 14 голов. По окончании контрольного выращивания провели контрольный убой бычков в 18-месячном возрасте. Установлено, что бычки I группы достоверно (Р<0,01) превосходили по живой массе аналогов II группы. Молодняк I группы имел более высокую (на 31,4 кг) предубойную массу и более тяжелые туши по сравнению с бычками II группы на 28,3 кг (Р<0,01). По убойной массе бычки I группы превосходили сверстников II на 26,5 кг (Р<0,01), а по убойному выходу — соответственно на 1,98 абс.%. При обвалке молодняка I группы было получено мякоти больше на 9,9 кг (Р<0,01) по сравнению с данными по обвалке туш бычков II группы. Химический анализ различных проб мяса показал, что туши бычков I группы содержали несколько меньше жира по сравнению с тушами молодняка II группы, как общего количества в средних пробах, так и внутримышечного в пробах из мускулов. Различия между группами по другим показателям были незначительными. Наибольшее количество жира было в отрубах, дающих лучшие сорта мяса, — бедренном и спинно-грудном, несколько меньше содержалось в лопаточной части, дающей мясо второго сорта. По влагосвязывающей способности, цвету и нежности мяса различий между группами не обнаружено. The analysis of the qualitative characteristics of the meat productivity of the Aberdeen Angus bull calves, depending on the body types, is carried out. Scientific and economic experience was conducted in one of the farms of the Karachay-Cherkess Republic in 2020-2021. From the offspring of large (group I) and small type bulls (group II) of the Aberdeen Angus breed, 2 groups of 14 heads were formed. At the end of the control cultivation, a control slaughter of steers was carried out at the age of 18 months. It was found that the bulls of group I were significantly (P<0.01) superior in live weight to the analogues of group II. The young animals of group I had a higher pre-slaughter weight (by 31.4 kg) and heavier carcasses compared to the steers of group II by 28.3 kg (P<0.01). According to the slaughter weight, the bulls of the first group exceeded the peers of the second by 26.5 kg (P<0.01), and according to the slaughter yield — by 1.98 abs.%, respectively. When deboning young animals of the first group, more pulp was obtained by 9.9 kg (P<0.01) compared with the data on deboning the carcasses of bulls of the second group. Chemical analysis of various meat samples showed that the carcasses of group I steers contained slightly less fat compared to the carcasses of young animals of group II, both total in average samples and intramuscular in muscle samples. The differences between the groups on other indicators were insignificant. The greatest amount of fat was in the cuts that give the best varieties of meat — femoral and dorso-thoracic, slightly less was contained in the scapular part, which gives the second grade meat. No differences were found between the groups in terms of the moisture binding ability, color and tenderness of the meat.

Group I, with the lowest mean live weight, had the lowest dressing percentage, relatively heaviest head and feet and lightest pelt, while group III, with the highest mean live weight, had the highest dressing percentage, the relatively lightest head and feet and the heaviest pelt of the three groups.Group I contained the lowest percentage, and group II, of medium live weight, the highest percentage of muscle, while the relative weights of bone and fat tissue were similar. Group III contained the highest percentage of fat tissue and the lowest percentage of bone. The differences in the relative weights of the edible internal organs between the three groups were not significant.Testis weight was relatively much greater in Group III than in the lighter animals. While dressing-out percentage increased with body weight, the increase was not equally distributed between fore and hindquarters. Hindquarters were relatively larger in group II than in group I; but the forequarters accounted for the greater part of the differences between groups II and III.

Introduction. In recent years, the production of feed additives of animal origin in Ukraine has declined sharply, and the cost of imported additives is very high. At the same time, in our country, the industry of industrial poultry farming has recently received intensive development, in particular, the cultivation and processing of broiler chickens for meat. At the same time, a significant amount of non-food waste from poultry slaughter in many poultry farms is not processed for feed purposes. Currently, an urgent problem is the organization of processing of non-food waste of poultry for feed purposes at poultry farms of industrial type of cultivation for meat of broiler chickens, primarily from blood and hydrolyzed raw materials. Processing of these wastes for feed purposes will not only give the opportunity to increase the production of high-grade protein feed, but also to significantly improve environmental safety. The purpose of our research is to study the meat productivity, safety, slaughter yield and quality of broiler chicken meat when feeding a combined feed additive from blood and hydrolyzed raw materials. Materials and methods of research. Development of an innovative technological line for the production of a combined feed additive from blood and hydrolyzed raw materials was carried out in LLC "Complex Agromars" (village of Havrylivka, Vyshgorod district of Kyiv region), and research on the effectiveness of feeding a combined feed additive from blood and hydrolyzed raw materials was performed in the production conditions of LLC "Bila Hora" Sniatynskyi district of Ivano-Frankivsk region. Research result. Development of innovative technological line was carried out in cooperation with engineering and technical staff of LLC "Complex Agromars". The innovative technological line is designed and installed using devices and mechanisms of the company "Haarslev Industries". In order to study the effectiveness of feeding a combined blood-feather feed additive for the experiment, four groups of broiler chickens of the Cobb 500 cross were formed, 50 heads in each, according to the following scheme: one group of broiler chickens was taken as a control group, and the next three groups – as research groups. Cultivation of broiler chickens in the experiment was carried out according to the traditional technology of feeding on standard compound feeds adopted in industrial broiler poultry farming, which, depending on the age and growth of chickens, includes 3 phases: "Start" – 14 days, "Growth" – 18 days, "Finish" – 12 days. According to the scheme of experience, the control group of chickens received standard feed without blood-feather feed additive. The difference in feeding of the broiler chickens of the experimental groups was in different levels of feeding with experimental combined feed additive from blood and hydrolyzed feather raw materials, which, depending on the age and growth of chickens, included in the feed of the I group from 4 to 12%, of the II group – from 3 to 10%, of the III group – from 2 to 8%. As a result of the studies it was found that at the end of the experiment at 44-day age the average live weight of broiler chickens of the control group was 2630 g, of the experimental group I – 2885 g, of the group II –2790 g, of the group III – 2680 g. For 44 days of experience the following amounts died: in the control group – 2 chickens, in the experimental group I – 1 chicken, in the group II – no chickens, in the group III – 1 chicken. Slaughter of broiler chickens and meat tasting was carried out in the company "Bilyi Bereh" of Ternopil region at the age of 44 days. It was established that the average slaughter yield of 1 carcass of broiler chicken meat was: in the control group – 1920, in the experimental group I – 2106 g, in the group II – 2037 g, in the group III – 1956 g. The difference in quality of meat of broiler chickens of control and experimental groups by results of tasting was not revealed. Summary: In LLC "Complex Agromars" (village of Havrylivka, Vyshgorod district of Kyiv region) designed and implemented an innovative technological line for production of ecologically safe combined feed additive from blood and hydrolyzed feather raw materials from non-food waste slaughter of broiler chickens when growing for meat. In the course of scientific and economic experiment it was found that the inclusion in the standard traditional feed in different phases of cultivation of broiler chickens for meat of about 4 to 12% of the combined feed additive from blood and hydrolyzed feather raw materials increased their average live weight from 2630g in the control group to 2885 g, and the average slaughter yield of 1 meat carcass – from 1920 g in the control group to 2106 g.

The purpose of research is beef production efficiensy growing of Black-Motley breed by use of natural drug Nukleopeptid. The research was carried out in SEC-farm «Hero» Chegmagushevskogo district of Bashkortostan. To carry out scientific and economic experience were formed 4 groups of Black-Motley breed calves at the age of 6 months, with 10 heads each. Groups were formed on the basis of analoge groups. The animals of the experimental group II had drug Nukleopeptid subcutaneously at dose of 20 ml, test group III – 25 ml and experimental group IV – 30 ml. The bulls of Group I is control and the drug is not administered them. In setting up the experience of the measurements of animals calves experimental groups had no significant differences in performance. Measurements of all groups of calves naturally increases with age. Studies have revealed that during the period of experience in the animals of group I height at the withers increased by 20.6%, height in the sacrum – by 17.9%, length of the body – by 38.4%, the depth of the chest – 37.3%, the width of the breast – 40.2%, putting backside – 25.5% femus width by 45.9%, whereas test groups in bulls (II-IV), these figures were above 0, respectively, 9-2.0; 0.5-1.4; 1.3-1.8; 0.1-1.0; 2.1-4.5; 1.8-3.6%. Indices body had the same trend. Gobies experimental groups, this applies especially to young animals of group III were more massive with well developed chest and back of the torso. It is proved that the introduction of new drug Nukleopeptid contributes to the meat productivity.

In a scientific and economic experiment lasting 90 days on 4 groups of black-and-white calves, formed by the method of analogs, the effect of a complex mineral-vitamin feed supplement (CMVFS ) on the nutrient digestibility of feed in the Republic of Bashkortostan was studied. Animals of the control group received the basic diet (BD) and mineral feeds (chalk, salt, premix); I, II and III experimental groups — BD + CMVFS according to recipe No. 1, No. 2 and No. 3 respectively. A distinctive feature of the recipes is the ratio of natural zeolite and sapropel in 1 kg of the supplement. It was found that the content of calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc and cobalt in the green mass, as well as in the feed harvested from it, does not meet the needs of young animals. Significantly high digestibility of dry and organic matter relative to the control was observed in animals of group III by 3.84% (R<0.05) and 2.78% (R<0.05); crude protein — by 3.21 and 3.96% — in young animals of groups II and III (R<0.05); crude fat — by 2.83% (R<0.05) in group I, by 4.01% (R<0.05) in group II and by 5.05% (P<0.01) in group III; nitrogen-free extractive substances — by 3.24% (R<0.05) in II and by 3.67% (R<0.05) in III experimental groups. The balance of nitrogen and minerals in all experimental groups was positive. The digested and deposited nitrogen in the body corresponds to the obtained average daily live weight gain of calves. In order to balance the diets of calves in terms of macro- and microelements, we recommend vitamins to introduce CMVFS according to the recipe No. 3 into the mixture of grains at the rate of 35 g per 1 head per day.

The article presents experimental data on the use of intrabreed selection in order to create the most effective productive type of sheep of the Stavropol fine-wool breed. In the zone of the dry steppe of the Volga region the sheep of the Stavropol breed were improved by the meat merino of the Australian selection. Scientific and experimental research was carried out in JSC “New Life” ofNovouzensky district of the Saratov region. The crossbreeds obtained during the step-by-step crossing of Stavropol sheep with tup-producers of Australian meat merino with 1/8-blood content according to AMM by eye-measuring the degree of severity of wool and meat productivity were distributed according to productive indicators (live weight, wool shearing) to the corresponding specific types of productivity. The first group — the uterus of the wool productive type; the second — wool-meat, the third — meat-wool. Each group of sheep was assigned to tuh of meat-wool productive type. The offspring were obtained according to the selection of parental pairs: father x mother. At birth, the M-W x M-W ewe hoggs had an advantage over the W x M-Wanimals in terms of live weight by 7.47%, and over the M-W x M-W — by 1.7%. After weaning at 4.5 months, the live weight of all young animals decreased slightly. In 13.5 months, the superiority of group III over group I and II was 9.3%, 4.6%. In terms of cutting physical wool, group II yarks outperformed group I and III by 1.91 and 3.45%, while their advantage in pure wool was 13.6 and 4.11%. The longest coat was characterized by the young animals of group I, the stronger coat was in the young animals of group III. In the structure of fine-wooled sheep of the Stavropol breed of the Volga population three productive types were distinguished, which differ from each other in terms of productive indicators: wool, wool-meat and meat-wool. At the same time sheep of the Stavropol breed, bred in the dry steppe of the Volga region, to a greater extent deviate towards the wool-meat productive type, such merinos of the combined direction in the conditions of the modern economic situation are most demanded and profitable.

Эффективность специализированного мясного скотоводства можно повысить за счет реализации интенсивных технологий. Целью нашей работы было изучение влияния различных уровней кормления бычков абердин ангусской породы по периодам выращивания, откорма, длительности производственного цикла на продуктивность и качество говядины. Длительность периодов и продолжительность производственного цикла были следующие: первый период колебался по I, II, III группам — 138, 155, 178 дней; второй — 145, 163, 186 дней; третий — 143, 161, 182 дня. Удельный вес концентратов по питательности составлял по группам 30, 40, 50%, а питательность израсходованных кормов за цикл соответственно 3233, 3045, 2914 ЭКЕ. В целом за весь производственный цикл выращивания и откорма бычки достигли одинаковой живой массы (441,5—445,3 кг). При этом животные III группы по среднесуточному приросту превосходили своих сверстников из I группы на 205 г, или на 28,7% (Р<0,001), а бычков II группы на 112 г, или на 15,7% (Р<0,001). Расход кормов на 1 кг прироста колебался от 7,7 корм. ед. в I группе до 7,0 корм. ед. в III (разница 11,0%), в то время как затраты концентратов в I группе по сравнению с III были меньше на 31% и во II — на 15,4%. Средняя масса парной туши по группам составила 235,8—240,4 кг, они имели хороший жировой полив туш (16,8—18,5 баллов) и убойный выход (53,4—54,0%). Наибольший уровень рентабельности получен при реализации бычков III группы (36,8%).The effectiveness of specialized beef cattle breeding can be improved through the implementation of intensive technologies. The aim of our work was to study the influence of different levels of feeding Angus breed Aberdeen bulls on the periods of cultivation, fattening, duration of the production cycle on the productivity and quality of beef. The duration of the periods and the duration of the production cycle were as follows: the first period ranged in groups — 138, 155, 178 days; the second — 145, 163, 186 days; the third period — 143, 161, 182 days. The specific weight of concentrates on nutrition was in groups of 30, 40, 50%, and the nutritional value of consumed feed per cycle, respectively, 3233, 3045, 2914 EKE. In General, for the entire production cycle of growing and fattening bulls reached the same live weight (441.5—445.3 kg). At the same time, animals of group III exceeded their peers from group I by 205 g, or by 28.7% (P<0.001), and bulls of group II by 112 g, or by 15.7% (P<0.001). Feed consumption per 1 kg of growth ranged from 7.7 feed. units in group I up to 7.0 feed. units in III (difference 11,0%), while the costs of concentrates in group I compared to III were less by 31% and in II — by 15,4%. The average mass of steam carcass of the groups was made amounting to 235.8—240,4 kg, they had a good watering fatty carcasses (16,8—18,5 points) and slaughter yield (53,4—54,0%). The greatest level of profitability obtained with the implementation of the calves of group III (36.8 per cent).
