ООО «PskovAgroInvest» pays great attention to the rearing of replacement young animals. The rate of increase in the intensity of raising heifers on the farm meets the standards and requirements of pedigree dairy cattle breeding. The farm uses stage-bystage rearing of replacement young stock, taking into account its age. A group approach to rearing young animals. Replacement heifers use natural and cultivated pastures in the summer. In recent years, the age of replacement heifers at the first insemination has noticeably decreased and approached the norm. At the same time, the live weight of animals at the first insemination increased, which in 2020 amounted to 460 kg, which opens up prospects for a further decrease in the age of the first insemination. This became possible due to an increase in the average daily growth in cultivation, which regularly increases every year and amounts to 756 g in 2020, which is 98 g, or 14.9%, more than in 2016. From table 2 it follows that in recent years, at all age periods, replacement heifers had a live weight exceeding the breed standard, which is 250 kg at 10-month-old, 290 kg at 12-month-old and 390 kg at 18-month-old age. At the same time, an increase in the average live weight of the replacement livestock is observed every year. So, in 2020, the value of the indicator was 278 kg at the age of 10 months, 331 kg at the age of 12 months, 463 kg at the age of 18 months, which is 16 kg, 54 kg and 75 kg, or 6.1%, 19, 5% and 19.3%, more than in 2016, respectively. Thus, the analyzed period allows us to conclude about the effectiveness of zootechnical work to improve the rearing of replacement heifers on the farm, but it must be continued in order to reduce the age of first insemination to 15–17 months with the optimal live weight of the livestock.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

The article presents the results of cross-breeding of mountain cattle with Russian polled breed. The growth and development of the crossbreed and purebred bull-calves of these breeds in the mountainous province of Dagestan have been studied in a comparative aspect. Efficiency of highland pastures use by crossbreed animals in comparison with pure-bred mountain peers has been established. The young cattle was grown according to the technology of meat cattle breeding “cow — calf”. In ablactation, the crossbred bull-calves had a living weight of 191.3 kg versus 159.3 kg in peers of mountain cattle. This figure was higher by 32.0 kg or 20.1% compared to purebred bull-calves of mountain cattle. At 12 months of age, the crossbred animals were also superior in living weight in comparison of young mountain cattle by 40.1 kg or 18.4%. According to this indicator, the advantage in crossbred animals at 15 months of age remained. The live mass of crossbred bull-calves at 18 months of age equaled to 399.5 kg against 332.6 kg of purebred mountain peers, the difference in favor of the former was 66.9 kg or 20.1%. Average daily growth of crossbreed bull-calves during the growing period was 122 grams or 20.8% higher. Young crossbred cattle had a clear advantage in terms of physique. Heavy carcasses with high slaughter yield were obtained from it. The conducted studies indicate the effectiveness of cross-breeding of mountain cattle with Russian polled breed in the mountainous province of Dagestan.

Studies were conducted on two groups of calves during the growing period from 1 to 6 months in conditions of unfavorable respiratory and gastrointestinal diseases. Calves of the experimental group with a diet were given dihydroquercetin and arabinogalactan at a dose of 1 and 75 mg/ kg of live weight / day, respectively. DHQ and AG, in accordance with their biological properties, provided a high level of antioxidant protection, the formation of microbiocenosis and intestinal immunity, correction and control of mineral homeostasis in the body of calves. As a result, there was a normalization and increase in the intensity of protein, nitrogen, lipid, carbohydrate, energy and mineral metabolism, improved the functional state of the liver and increased pathogenetic resistance, which generally had a positive effect on the formation of productive health, viability and resistance of the body to the action of biotic and abiotic environmental factors, safety and average daily growth of calves.

Based on the use of the best domestic and world gene pool of the Holstein breed, a domestic highly productive breed of cattle with a genetic potential of more than 10 000 kg of milk per lactation adapted to the climatic conditions of Siberia was created. When breeding it, different reproductive crosses were used. As a result, a competitive livestock breed with a population of 26 770 heads was obtained. The productivity of 10 129 cows at the time of breed testing averaged 7,461 kg of milk with a fat content of 3.78% and a protein content of 3.16%. In terms of milk yield and protein content in milk, they surpass Black-and-White cows by 1,460 kg and 0.05%, respectively. However, the animals of the original breed have a higher fat content of milk, by 0.14%. The live weight of cows of Sibiryachka breed is 36 kg (6%) more than that of Black-and-White cows. Young animals of the new breed are intensively growing and developing. At all ages, their live weight is higher than Black-and-White peers. The average daily increase from birth to one year for heifers of the new breed was 770 g, for Black-and-White peers – 700 g. For a growing period of up to 18 months, daily growth averaged 706 and 673 g, respectively. The live weight of heifers at 18 months is 424 kg, Black-and-White – 405 kg, which allows insemination of heifers of Sibiryachka breed 24 days earlier. The average yield of calves over 3 years in the new breed was 82.7%, in the original one it was 3.7% less. The period of use of the cows of the created breed is 3.47 calving, which is 8% more compared to the Black-and-White breed.

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.

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.

The results of evaluating the breeding value of rams of different genotypes by a wide range of productivity indicators of their descendants are presented. Tribal rams of the Kharkov interbreed type of Prekos breed of 2-3 years of age, as well as crosses from the introductory crossing of Prekos sheep with the Romanov breed and Merinolandsheep, were evaluated. The resulting offspring were grown under the conditions of one production flock. The evaluation considered the indicators of the reproductive ability of ewes, sex and type of birth of the offspring, the safety of lambs from birth to 20 days of age, the dynamics of the average daily growth of daughters in the uterus and at the age of birth to 20 days and from 21 to 90 days, live weight indicators were considered, cutting and length of hair of daughters at the age of 14 months. Studies have established that the average yield of lambs throughout the sample was 115.3 % per 100 ewes, with significant differences between the estimated producers - from 105.1 to 131.3 %. This indicator did not have a definite relationship with the genotype of the estimated sheep. Among the offspring of all rams, males slightly prevail over females in the ratio of 1.09 to 1. This advantage is due to the large number of rams born among same-sex twins. Their part exceeded 28 %, while only 23.4 % turned out to be similar in type of birth. By the sum of the ranks that were put to individual sheep for the indicators of the average daily growth of daughters at different periods of their growth, the best cross-breed sheep No. 1625 and No. 9953 are distinguished. On the whole, there is a fairly clear tendency for a positive relationship between the ranks for the growth rate in the embryonic period and the same indicator for posterity aged 21-90 days. According to both the ranking and the probity-based evaluation results, ram No. 1625 (a created line based on crossing with the Romanov breed) is assigned to complex improvers. The rest topping ram out to be improvers of individual traits, and the producer of the breed Prekos No. 1823 was an improvement in production of wool and length of staple. Ram No. 1960 turned out to be a complex deteriorator in the quality of offspring. The descendants of rams No. 4464 and 9953, derived from the breed of Merino landscape, reliably (p≤0.01), by 18.6-20.8 % in terms of wool coefficients, are inferior to the daughters of ram No. 1823, breed Prekos, which is an unconditional evidence of the strengthening of their characters meat productivity over wool one.

Relevance. Modern turkey crosses have a genetically determined high growth rate. These farm birds are very sensitive to even minor fluctuations in their diet, are susceptible to a deficiency of amino acids, protein, mineral elements and vitamins, which can contribute to a decrease in their productivity, the development of pathological processes and diseases. The use of modern technologies and scientific achievements has made it possible to prepare a new product — modified zeolite. This natural mineral is already free of impurities and microbes, with open pore windows, has a high ability to selectively exchange, and is obtained by various methods of activating zeolite in industrial conditions. At the same time, Ulyanovsk specialists have mastered the technology of enriching modified zeolite with useful substances.Methods. The aim of the work was to study the effect on the body of turkeys and the level of their productivity of additives based on modified zeolite enriched with amino acids. The experiment was organized for 60 days on 250 turkeys of the breed Hybrid Cread-mayker aged 55–60 days in the conditions of the Ulyanovsk region. The control group received the main ration (MR), the experimental group was given once a day in addition to the MR in the morning feeding in a mixture with mixed feed 5% additives of modified zeolite enriched with amino acids.Results. The inclusion of a supplement based on modified zeolite enriched with amino acids in the diet of turkeys does not have a negative effect on the hematological parameters of their blood, all indicators corresponded to the physiological norm. During the experiment in the 2nd group, the live weight of poultry was obtained larger by 8.70%, which amounted to 12,296 kg, respectively, more profit was obtained from the sale of turkey meat, total revenue was 133,210, and additional profit was 27,960 rubles, 2.41 rubles of profit was received for 1 ruble of costs. Тhe data indicate the normalization of mineral homeostasis in the body of turkeys and better absorption of nutrients in the feed diet.
