Изучены особенности роста и развития  молодняка крупного рогатого скота при выращивании в ранний период онтогенеза после применения фитосредств на основе водно-дисперсной вытяжки из древесины березы и лиственницы, позволяющих активировать обменные процессы в организме  и повышать прирост живой массы телят соответственно на 20,3 и 34,5%. Гематологические исследования показывают, что интенсивный рост молодняка сопровождается динамикой содержания в сыворотке крови белка, кальция, фосфора, глюкозы, щелочной фосфатазы, которые в дальнейшем можно использовать в качестве тестов для раннего прогнозирования роста телят в промышленных комплексах. The features of growth and development of young cattle during growth in the early period of ontogenesis after using the phytosupplements on the basis of a water dispersed extract from birch and larch wood allowing to activate metabolic processes in an organism and to increase a gain of live weight of calves by 20,3 and 34,5% respectively have been studied. Hematological studies show that the intensive growth of young calves is accompanied by the dynamics of serum protein, calcium, phosphorus, glucose, alkaline phosphatase, which can be further used as a test for early prediction of calf growth in industrial complexes.

Due to the intensifi cation of the cattle breeding industry, there is a need to fi nd ways and available methods to increase production and improve the quality of beef based on the use of existing breeding stock of dairy cattle. The success of industrial crossbreeding depends primarily on the correct selection of breeds and their compatibility. The purpose of the research was to study the growth and development of purebred young cattle of Black-and-White breed and crossbreeds with Hereford breed in the Leningrad region. Research and production experiment has been carried out in the training and research farm “Pushkinskoe” of the St. Petersburg State Agrarian University. In the control group purebred animals of Black-and-White breed (9 heads steers and 7 heads heifers), in the experimental group half-blood animals (9 heads steers and 7 heads heifers) have been selected obtained as a result of crossbreeding Black-and-White cows and Hereford sires. The researches have been conducted from birth to 18 months of age. Researches have shown that the crossbreed young animals in comparison with purebreds were distinguished by expressed meat type of physique, a squat body with a welldeveloped back, a fairly wide and deep chest and a strong bone structure. Crossbred animals have been characterized by increased growth intensity. Steers and heifers outperformed their Black-and-White herdmates in terms of daily live weight gain overall over the study period by 170,6 g or 18,8 % , and 130,2 g or 15,6 %, respectively (P ≤ 0,01–0,001). According to the research results, it is recommended that to increase the volume of beef production and more fully realize the productive potential of cattle in the Leningrad region, it is necessary to conduct industrial crossbreeding of holstinized Black-and-White cattle with Hereford cattle. The resulting crossbreed young animals should be raised and fattened up to 16 months of age when steers reach a live weight of 540 kg and feed expenditures per 1 kg of live weight gain of 6,4 EFU, and heifers more than 480 kg and 6,9 EFU, respectively.

Изучены рост и развитие бычков — помесей красной степной с казахской белоголовой породой в равнинной провинции Дагестана. Установлено, что помесный молодняк, по сравнению с чистопородным скотом красной степной породы, имеет более высокую живую массу при рождении на 1,8 кг, или 7,3%. При отъеме в 8-месячном возрасте помеси имели живую массу 210 кг против 187,6 кг у красного степного молодняка, что на 22,4 кг, или 11,9% выше. В 12-, 15- и 18-месячном возрасте живая масса помесных бычков равнялась 291,8 кг, 359,7 и 436,6 кг, соответственно, или на 28 кг, 36 и 45,8 кг больше по сравнению с красным степным скотом. Среднесуточные приросты помесных бычков за период выращивания и откорма составили 760 г, что выше на 12,1% по сравнению с чистопородным красным степным молодняком. После заключительного откорма и убоя помесные бычки дали тяжеловесные туши с хорошим поливом. По массе парной туши они превосходили чистопородных аналогов на 31,3 кг, или 15,6% с преимуществом выхода туши на 2,4%. Убойный выход у бычков опытной группы составил 58,7%, контрольной — 55,8%. От помесных бычков были получены тяжеловесные шкуры массой 27,1 кг, от чистопородных — 21,6 кг, преимущество по этому показателю имели помесные животные 5,5 кг, или 25,4%. Для увеличения производства говядины в равнинной провинции Дагестана рекомендуем скрещивание коров красной степной породы с быками казахской белоголовой породы. The growth and development of bulls of red steppe crossbreeds with the Kazakh white-headed breed in the flat province of Dagestan were studied. It was found that young crossbreed animals in comparison with purebred red steppe cattle have a higher live weight at birth by 1,8 kg or 7,3%. When weaning at 8 months of age, cross-bred bulls had a live weight of 210 kg against 187,6 kg in red steppe young, which is 22,4 kg, or 11,9% higher. At 12, 15 and 18 months of age, the live weight of crossbred bulls was 291,8 kg, 359,7 and 436,6 kg, respectively, or 28 kg, 36 and 45,8 kg more than the red steppe cattle. The average daily growth of cross-bred bulls during the growing and fattening period was 760 g compared to 678 g, that is, they were 12,1% higher compared to purebred red steppe young. After the final fattening and slaughter, the cross-bred bulls gave heavy carcasses with good watering. By weight of the paired carcass, they were superior to purebred counterparts by 31,3 kg or 15,6% with an advantage of 2,4% carcass yield. The slaughter yield of bulls in the experimental group was 58,7%, 55,8% in the control group, respectively, with an advantage in favor of crossbreeds of 2,9%. Heavy skins weighing 27,1 kg were obtained from crossbreed bulls, 21,6 kg from purebred ones, and crossbreed animals of 5,5 kg or 25,4% had an advantage in this indicator. Studies have shown that in order to increase beef production in the lowland province of Dagestan, it is necessary to use crossbreeding of the breeding stock of the red steppe breed with bulls of the Kazakh white-headed breed.

Abstract The early period of postnatal ontogeny of sheep is characterized by a variety of metabolic processes that result in the formation and consolidation of a certain type of metabolism. A special role is played by lipids, which together with proteins and carbohydrates constitute the bulk of organic compounds, cells and the organism as a whole. The purpose of this research was to study the polymorphism of CAST and GH genes as well as its association with the fatty acid composition of blood plasma lipids in lambs. The content of fatty acids was determined by gas-liquid chromatography in the form of methyl esters. From the data obtained, it follows that in all studied ontogeny periods the peripheral blood of sheep with CASTNN and CASTMM genotypes had a higher concentration of fatty acids such as palmitic, stearic, linoleic, and arachidonic acids. The content is as follows: 27.58, 45.40, 3.16, 0.28% vs. 26.21, 45.31, 3.62, 0.18% at the age of 2 months; 25.07, 43.25, 6.05, 1.74% vs. 23.24, 38.76, 6.49, 1.32% at the age of 4 months; 20.64, 22.26, 14.17, 3.38% vs. 17.64, 19.91, 15.07, 2.46% at the age of 8 months (P ˂ 0.05), (P ˂ 0.01). Studies of blood lipid composition of GHBBand GHAA genotype carriers showed that palmitic, stearic, linoleic, and arachidonic acids were dominant: 27.95, 27.96, 19.04% vs. 26.08, 23.88, 17.56% at the age of 2 months, 46.87, 39.87, 22.37% vs. 3.24, 6.87, 15.56% at the age of 4 months; 0.45, 1.68, 3.81% vs. 0.29, 1.29, 3.19% at the age of 8 months (P ˂ 0.05), (P ˂ 0.01). Thus, this study emphasizes that there is a close relationship between the ratio of fatty acids in total blood lipids in lambs and the intensity of growth and development, ensuring and controlling the direction of biochemical processes in the growth and development of young sheep.

The protein, vitamin and mineral supplements have been developed and it was studied the efficiency of feeding with them the young cattle in the composition of the grain production. The scientific and farm experiment has been carried out during 62 days. The study was conducted in four groups of bulls with 12 heads in each. The initial live weight at the beginning of the study was about 300–310 kg. Differences in feeding were in the fact that the grain forage for young animals of group I included PVMS No. 1, II – PVMS No. 2, III –PVMS No.3, IV – PVMS No 4. The grain feed is represented mainly by barley. The protein, vitamin and mineral supplement replenished 20 % of the deficient protein. It was discovered that concentration of hydrogen ions was practically at the same level in the rumen contents of steers of different groups. As for level of ammonia, VFA, total nitrogen, ciliates in the young cattle of I, II and III groups, the differences were insignificant. The concentration of ammonia of group IVcompared to I, II and III group was higher by 15.58, 23.61 and 21.9 %, VFA – by 6.7, 19.4 and 11.1 %, total nitrogen – by 3.32, 31.44 and 24.03 %, ciliates – by 4.35, 14.29 and 9.09 %, respectively. The research results showed that digestibility of protein, fiber and BEV was higher in the fourth group by 1–7 % compared with the rest groups (P>0.05). A slight increase in nitrogen deposition was found in IV group of young animals (by 4.7–11.9 %) receiving PVMS with AFA as a source of protein. The use of calcium and phosphorus by animals was almost at the same level. The research helped to determine that the average daily weight gain of animals of all the groups was within the range 629–710 g. The highest was in the fourth group consuming PVMS No. 4 with AFA as a protein component; the second place in terms is occupied by group I – 660 g, consuming PVMS No. 2, which included lupine, AFA and standard DKMK No. 1; PVMS No. 3 with depleted phosphate used as a source of phosphorus, took the last place in terms of this indicator – 629 g. Feed cost per 1 kg of weight gain was the lowest in IV group – 8.77 feed units, in I, II and III groups, it was higher by 8.32 %; 13.68 and 10.83 %, respectively. The cost of sold products from one animal during experiment turned out to be higher for steers that received PVMS No. 4 as compared to I, II and III groups by 6.82, 11.36 and 9.1 %, respectively.

We performed have performed a comprehensive analysis of the meat productivity of cattle received for slaughter and primary processing at “Uvinsky meat factory” OOO of the Uvinsky district in the Udmurt Republic. The studies were carried out based on data from plumb lines for 2020. During the research, it was revealed that only two districts (Uvinsky and Vavozhsky) had got cattle in 2020, from which they obtained carcasses of the “super” category (21 pieces). This is the highest grade in terms of categorization. Meanwhile, the main range of carcasses of young cattle was assessed in the categories “extra”, “excellent” and “good” (1311 carcasses). However, there were also farms from which carcasses of the “low” fatness category were obtained (Uvinsky, Seltinsky and Vavozhsky districts) (42 carcasses). Based on the results of the commodity evaluation of carcasses of adult cattle, it is worth noting that most of the carcasses were quite well-fed and were rated in the first category. By the end of 2020, the company has obtained meat in carcasses from young cattle in the amount of 608.8 tons. Meanwhile, 917.5 tons of meat were produced in live weight. The meat volume in the carcasses of adult cattle was 180, 1 ton. In live weight, 386, 5 tons were obtained. Given the percentage of beef sales per year and the maximum yield of boneless meat, the company is not capable of fully meeting the needs of all high-level processing shops.

Positive Effect

On the basis of the "Komarova" farm (Magadan, Magadan region), the effect of introducing a new non-traditional component feed additive of plant origin into the diets of young cattle was studied. The research was carried out during the stall period. For the experiment there were taken four groups of animals (14-16 months of age) divided at random in accordance with the genotype into control and experimental groups of ten animals each. The first two groups (control, experiment) included purebred Holstein bulls, the other two – hybrids of the 1st generation (1/2 Holstein × 1/2 Herefords). For the experimental groups, the main diet was supplemented with a component feed additive consisting of cedar elfin (Mountain pine) flour and lichens (alpine cladonia (Cladonia alpestris), Icelandic cetraria (Cetraria islandica)). The results of the experiment has shown that the feed additive, consisting of 120 g of cedar elfin needle flour and 50 g of lichen flour (80% of Cladonia alpestris and 20% of Cetraria islandica), has a positive effect on the intensification of metabolic processes in the animals. The digestibility of crude protein increased by 1.29-4,19 g (1.7-5.6 %); that of the organic matter – by 6.65-8.90 g (11.0-14.3 %); NFE (nitrogen-free extracts) – by 7.80-9.18 g (14.14-15.70 %). An increase in the digestibility of feed nutrients had a positive effect on an increase in live weight gain by 0.60-3.0 g (1.35-5.93 %). An increase in feed conversion was 0.24-6.8 MJ (0.20-6.74 %); feed protein – by 0.02-0.09 g (1.22-6.17 %). Crossbred bulls turned out to be more responsive to changes in the ration of feeding and showed better results in all studied parameters. The effectiveness of using the additive is due to the fact that the raw material for the production is obtained from wild plants growing in nature in sufficiently large volumes. They do not require significant costs for harvesting and preparation for feeding.
