The article analyzes the genetic structure of antigenic erythrocyte factors of dairy, dairy-meat and meat breeds of cattle bred in breeding farms of the Republic of Bashkortostan. The data on the level of genetic variability and immunogenetic similarity of the studied breeding groups of animals were obtained. It was found that all breeds have a high concentration of antigens F, A2, H', C2, Z and a low concentration of antigens G1, J2', U". In the studied sample of cows there are no two antigenic factors – G' and B' in cows of Limousine breed. In general, genetic similarity indices between breeds range from 0,790 to 0,937. At the same time, planned breeds (Black-mottled, Simmental and Bestuzhevskaya), bred on the territory of the Republic of Bashkortostan for a long time, regardless of whether they are dairy or combined directions of productivity, are closer in genetic relation to each other and are approximately equidistant from each other. The lowest immunogenetic similarity was found between breeds of meat productivity direction. The greatest number of antigens found in the blood of animals Simmental and Bestuzhevskaya breeds from 12,2 to 12,0, respectively. The average number of antigenic erythrocyte factors in animals of meat breeds is about the same as in black-and – white cows (9,0–10,8). Thus, it can be stated that the studied breeds of cattle of Bashkortostan formed their own unique allelofund antigenic erythrocyte factors of blood, which characterizes their originality, associated not only with the intensity of use of producers of different origin, but also the processes that contribute to the possibility of adaptation of animals in specific environmental conditions.

Aim: This study aimed to determine the effect of thyroglobulin (TG5) gene polymorphism on milk and meat productivity in the various cattle breeds currently bred in the Republic of Bashkortostan. Materials and Methods: The test was performed on dairy cattle of Black-and-White, Bestuzhev, and Simmental breeds, and meat cattle of Hereford and limousine breeds. The purpose of the test was to search for associations between the polymorphic alleles of the thyroglobulin (TG5) gene and economically useful traits. Results: All studied breeds showed a frequency predominance of the TG5C allele (from 0.56 to 0.71). A clear trend of an effect of the genotypes of the TG5 gene on milk-productivity indicators was revealed; cows with the TG5TT genotype have the highest milk yield and fat content in milk. The milk of cows of Bestuzhev and Simmental breeds that possessed this genotype was also characterized by higher protein content. Conclusion: We identified an effect of the polymorphism of the TG5 gene in the Hereford and limousine breeds on fat metabolism intensity indicators, such as fat output and fat content, in the longissimus muscle and in the general sample of ground beef.

Breeding Groups

The assessment of black-and-white, red steppe, and Simmental cattle, differentiated by milk fat was carried out. Three groups were formed: selection, production and marriage. The selection parameters are calculated using the standard deviation. The calculated parameters of selection of animals of the breeding group for milk fat in adult black-and-white cows are at least 179 kg, red steppe - 186, Simmental breed from the Novosibirsk region - 143, the Republic of Khakassia - 176 kg. Cows of the red steppe breeding group are leading in productivity. Their milk fat index is 216.8 kg (P ≥ 0.95). In animals of the black-and-white breed, the milk fat productivity is 193.2 kg. In the Simmental Republic of Khakassia it is 193.8, in the Novosibirsk region - 163.5 kg. Analysis of interbreed differences in cows of breeding groups shows that animals of the black-and-white breed surpass their peers in chest width behind the shoulder blades, milk yield and milk production index. Animals of the red steppe breed are the best in milk fat, live weight, width in shanks, oblique body length, oblique rear length, chest girth, milk fat content. Simmental cows bred in the Novosibirsk region lead over their peers in height at the withers, and Simmental cows in Khakassia - in height at the sacrum, chest depth, cannon girth, assessment of the exterior. Evaluation of the production groups of animals for milk fat allows to note that the selection group of the black-and-white breed, despite the superiority in milk yield, is inferior to the peers of the red steppe and Simmental in terms of the evaluated character. However, the cows of the black-and-white breed of the production group surpass their peers in milk fat and most other signs. The formation of breeding groups for milk fat enables to note the consolidation of the black-and-white breed in terms of productive and exterior characteristics. The Red Steppe and Simmental breeds have a high potential for improvement. These breeding groups are worthy of competing with the contemporaries of the black-andwhite breed in milk fat productivity.

В статье приводятся показатели, характеризующие рост и уровень мясной продуктивности бычков черно-пестрой породы при скармливании им люцернового сенажа, заготовленного с разной дозировкой биозакваски на основе пропионовокислых бактерий. Препарат вводили в процессе закладки сенажа в виде рабочего раствора в количестве 2, 4 и 6 л на 1 т консервируемой массы. Опыт проводился в условиях Республики Башкортостан. Для этого 40 10-месячных бычков разделили на 4 группы. Молодняк контрольной группы получал неконсервированный сенаж, а опытных групп — сенаж, с закваской на основе пропионовокислых бактерий в указанных выше дозах. Установлено, что молодняк опытных групп лучше рос и развивался. В 12 мес его живая масса была выше, чем в контрольной группе на 2,50—6,10 кг (0,73—1,77%); в 15 мес — на 9,34—15,14 кг (2,20—3,57%; Р<0,05); в 18 мес — на 15,51—23,31 кг (2,10—4,66%; Р<0,05—0,01). Более высокая энергия роста молодняка опытных групп при откорме на рационах, включающих консервированный сенаж, способствовала и более высоким убойным показателям. Наилучший эффект проявился у бычков, потребляющих сенаж с закваской на основе пропионовокислых бактерий в дозе 4 л рабочего раствора на 1 т зеленой массы. Данная дозировка обеспечивает увеличение массы парной туши на 12,9 кг (4,79%),The article presents the indicators characterizing the growth and level of meat productivity of bull-calves of the black-and-white breed, when they are fed alfalfa haylage, harvested with different dosages of biosakvaski based on propionic acid bacteria. The drug was administered in the process of laying haylage in the form of a working solution in the amount of 2, 4 and 6 liters per 1 ton of preserved mass. The experiment was conducted in the conditions of the Republic of Bashkortostan (Alga, collective farm, Chekmagushevsky district). For this 10-month gobies were divided into 4 groups. The young of the control group did not receive canned haylage, but the test groups received haylage, with sour based on propionic acid bacteria in the above doses. It was found that the young of the experimental groups grew and developed better. So at 12 months of age, their live weight was higher than in the control by 2.50—6.10 kg (0.73—1,77%); in 15 months — by 9,34—15,14 kg (2,20—3,57%; P<0,05); in 18 months — by 15,51—23,31 kg (2,10—4,66%; P<0,05—0,01). The higher growth energy of the young of the experimental groups during fattening on rations, including canned haylage, contributed to a higher slaughter rate. The best effect was manifested in calves consuming haylage with ferment based on propionic acid bacteria in a dose of 4 liters of working solution per 1 ton of green mass.This dosage provides an increase in the mass of steam carcass by 12,9 kg (4,79%), carcass output by 1,0%; slaughter weight — by 14,0 kg (4,95%; P<0,05); slaughter yield — by 1,2%.

Technological Methods

One of the key areas of development of the cattle breeding industry in Russia is the creation of effective technological methods. They allow to carry out the improvement and establishment of new resource-saving systems for breeding young animals at an accelerated pace. It is essential to meet the modern requirements of meat production as an ecologically safe product. The aim of the research was to enhance the fattening qualities of Hereford bull calves while using mode-setting suckling of various ratios as an element of resource saving. The study was performed on "SAVA-Agro-Yapryk" OOO of the Tuymazinsky district of the Republic of Bashkortostan. The determination of the efficiency of the use of free and mode-setting suckling of various ratios made it possible to identify an effective method of raising young meat cattle. A three-fold mode suckling is used with separate keeping of young animals and mother cows. This makes it possible to keep the optimal microclimate parameters in the calf house, contributes to the rapid early adaptation of calves to the consumption of coarse feed and concentrates. It has a positive effect on the growth and development of calves and their meat productivity at the age of 18 months according to the parameters of removable fat mass, carcass mass and interior fat mass. All this promotes an increase in the sale of beef and an improvement in the level of production profitability to 13.93%.

Increasing the protein nutritional value of rations through the use of legume-grass crops, press-cakes and oil-cakes, complete provision of high-quality animal feed, balanced in protein and other components, is the leading direction of solving the protein problem in animal husbandry and remains an urgent topic for research. The purpose of the research was to study the use of hay and haylage from the mixture of Eastern galega and awnless brome in the rations of first-calf heifers instead of the same feed from the mixture of alfalfa and awnless brome. For carrying out scientific and economic experiments in LLC Kushul in the Dyurtyulinsky district in the Republic of Bashkortostan on the principle of pairs-analogs (breed, live weight, age, level of productivity) four groups of first-calf heifers of Black-and-White breed per 10 heads in each have been selected. The inclusion of 4 kg of hay and 10 kg of haylage in the rations of first-calf heifers of the mixture of Eastern galega and awnless brome has a positive effect on increasing the protein content in milk by 3,1 and 3,4 %, sugar by 0,6 and 0,9 abs.%. There was a steady increase in the milk of cows of the experimental groups: carotene, total calcium and inorganic phosphorus compared to the control group where the animals received 4 kg of hay and 10 kg of haylage of the mixture of alfalfa and awnless brome. Thus, studies have shown that the use in rations of first-calf heifers hay and haylage of mixtures of Eastern galega and awnless brome promotes not only productivity, but also improve milk quality.

The results of the evaluation of the effect of alfalfa haylage harvested with preservatives on the efficacy of bioconversion of nutrients and energy rations in meat products. Scientific and economic experience held in the SEC-farm «Alga» Chekmagushevsky district of the Republic of Bashkortostan. There are three trench silage from alfalfa. In one of them the food was laid with the application of the preservative Laxil, the second – and third Silostan – no preservatives. Laxil preservative was added at the rate of 1 liter per 15 tons of green mass, Silostan – 1 liter to 150 tons. The object of research was 45 bulls of black-and-white breed at the age of 9 months, of which three groups were formed: control and two experienced. Gobies control group received silage of alfalfa harvested without preservatives, and the animals of I and II experimental groups – silage, preserved by Laxil and Silostan. For studying of meat productivity and quality of meat of test bulls control slaughter of 3 bulls from each group was carried out. The results of the study indicate the superiority of calves of the experimental group over their counterparts from the control groups both in vivo and post-slaughter parameters. The results of the evaluation of the transformation of protein and energy feed in the production of bulls compared groups when grown for meat indicate that in the body of young I and II experimental groups were deposited a little more protein compared with peers from the control group.

В условиях племрепродуктора в Республике Башкортостан были проведены опыты по изучению влияния селеносодержащего препарата ДАФС-25 на рост и мясную продуктивность бычков симментальской породы. В опытной группе животные характеризовались более высокой интенсивностью обменных процессов. Они превосходили по содержаниюбелка в крови бычковконтрольнойгруппы, где разницасоставила в 3 мес 0,9 г/л (1,17), в 6 мес 1,41 г/л (1,84), в 12 мес 1,54 г/л (1,99), в 18 мес 1,18 г/л (1,51). Установлено, что у животных, получавших добавку, активность ферментов АСТ и АЛТ была выше, чем в контроле, соответственно, на 0,100,22 ед. (2,7013,74), что положительно отразилось на интенсивности формирования мясной продуктивности. Лучшей энергией роста в течение опыта обладали бычки опытной группы, они имели преимущество по живой массе к концу опыта 23,7 кг (7,4). Бычки опытной группы превосходили аналогов из контроля по живой массе в возрасте 3, 6, 9,12, 15 месна 2,2 кг (2,56), 6,1 (4,25), 11,9 (5,74), 15,2 (5,42), 17,2 кг (5,13). Результаты контрольного убоя свидетельствовали, что скармливание ДАФС-25 бычкам опытной группы способствовало интенсивному увеличению живой массы и мясной продуктивности. Масса парной туши у бычков 18-месячного возраста опытной группы была на 14,28 кг (6,96) выше, чем в контроле внутреннего жира на 1,95 кг (21,33), убойной массы на 16,23 кг (7,57). У животных опытной группы убойный выход был выше на 1,05, по сравнению с бычками контрольной группы. У бычков, получавших подкормку, масса мякоти была больше на 20,31 кг, что составляет 13,05 (Р0,001). Туши животных опытной группы характеризовались лучшим соотношением в них мяса, жира и костей. Мякоти на 1 кг костей приходилось 4,56 кг, или на 0,23 кг (5,31) больше, чем в контроле.Research directed at studying the influence of selenium-based feed additive, DAFS-25, on the growth and meat productivity in calf bulls of Simmental breed was carried out under the conditions of a pedigree breeding unit located in the Republic of Bashkortostan. The animals included in the test group was characterized by increased intensity of metabolic processes. The level of blood protein of animals from this group exceeded the level of blood protein of animals from control group. The differences at the age of 3 months amounted to 0.9 g/L (1.17), 6 months 1.41 g/L (1.84), 12 months 1.54 g/L (1.99), 18 months 1.18 g/L (1.51). It was found that the activity of AST and ALT enzymes in animals that received the additive was higher by 0.10-0.22 u (2.70-13.74), respectively, than that in animals included in control group, which positively influenced the intensity of meat productivity formation. Calf bulls from the test group showed the best growth energy during the experiment. Their live weight advantage by the end of the experiment amounted to 23.7 kg (7.4). Test group calf bulls were superior to the analogues belonging to control group by live weight: by 2.2 kg (2.56), 6.1 (4.25), 11.9 (5.74), 15.2 (5.42), and 17.2 kg (5.13) at the age of 3, 6, 9, 12, and 15 months. The results of control slaughter showed that feeding DAFS-25 to calf bulls belonging to test group facilitated intensive growth of live weight and meat productivity. Hot carcass weight of 18-month-old calf bulls belonging to test group by 14.28 kg (6.96) exceeded the result of control group test group animals also exceeded those from control group by the following parameters: internal fat by 1.95 kg (21.33), slaughter-weight by 16.23 kg (7.57). Slaughter yield of test group animals was higher by 1.05 compared to calf bulls attributed to control group. Flesh weight of calf bulls who received the additive was higher was 20.31 kg more, which amounts to 13.05 (P0.001). Carcasses of test group animals were characterized by better ratio of meat, fat, and bones. There was 4.56 kg of flesh per 1 kg of bones, or 0.23 kg (5.31) more than in control group.
