Abstract The paper presents the results of fattening young cattle in the conditions of Yakutia with the use of complex feed additives from local natural raw materials in their diets. One of the ways to increase the meat productivity of livestock is to optimize feeding by inserting complex feed additives into their diets. Therefore, studies were conducted to determine the effectiveness of complex feed additives in the fattening of young cattle in the conditions of Yakutia. At the beginning of the experiment, the live weight of the animals in the groups did not differ much, but starting from the age of 12 months, the superiority of the animals from the experimental groups is noted. In the period of 12-15 months of age, the animals from the experimental groups exceeded the growth rate of the control group by 6.70% and 4.76%. In the period of 15-18 months old, the animals of the control group were inferior to the experimental groups by 28.31% and 16.54%. On average, the animals of the experimental groups grew more intensively in comparison with the control group by 12.73% and 8.66 %. Analysis of animal slaughter data showed that the experimental groups were superior to the control group in a number of indicators, such as the mass of the steam carcass by 8.04% and 4.43 %, the mass of visceral fat by 18.59% and 7.39%. The organoleptic evaluation of meat products also confirmed the superiority of the experimental groups over the control group. Thus, the use of complex feed additives in the feeding of young cattle on fattening showed its effectiveness.

Abstract The paper presents the results of a study to determine the effectiveness of complex feed additives in the fattening of culled cattle in the conditions of Yakutia. To conduct the experiment, 3 groups of culled cattle were formed. The use of complex feed additives from local natural raw materials in the feeding of culled cattle on fattening allowed increasing the live weight by 1.58% and 0.26%. To determine the safety of experimental feed additives, the clinical parameters of the body of experimental animals were studied. It was found that there was no significant difference between the groups and all the indicators were within the normal range, which in turn proves the harmlessness of complex feed additives. At the end of the experiment, a control slaughter of experimental animals was carried out. When analyzing the data of animal slaughter, it was found that the experimental groups were superior to the control group in terms of parameters: the mass of the steam carcass by 5.53% and 3.61%, the mass of visceral fat by 9.39% and 1.77%, the slaughter mass by 6.07% and 3.87%, the slaughter yield by 2.76% and 2.06%. Next, the organoleptic evaluation of meat products was performed. According to the results of the evaluation of boiled meat, it was found that the experimental groups exceed the control group by 12.92% and 8.33%, and exceed the roasted meat by 11.87% and 8.19%. Thus, complex feed additives showed effectiveness in fattening culled cattle in the conditions of Yakutia.

This paper presents the results of studying the conversion of feed into nutrients in the carcass of bulls during the fattening of young Kalmyk breed in the conditions of Yakutia. The studies were carried out on the basis of the Soloosun agricultural production complex, Megino-Kangalassky region. The experiment was organized on Kalmyk bull-calves fed from 15 to 18 months of age. There were formed 2 groups of 25 bulls analogs: the control and the experimental one. The animals of the control group were fed according to the ration adopted on the farm. The diet of the animals from the experimental group included 200 g of Hongurin zeolite and 45 g of Kempendyai salt per animal. The main ration of animals by structure consisted of meadow hay 46%, haylage – 22% and compound feed 32% or 12.57 EFU per day. At the beginning of the experiment, the live weight of the animals was almost identical. At the end of fattening, the bulls of the experimental group in live weight exceeded the animals of the control group by 10.9 kg. Consequently, the experienced bulls had higher bioconversion rates, which was reflected in an increase in the meat productivity of animals. The analysis showed that the control group of bulls was inferior to the experimental group in terms of pulp by 11 kg., In the deposition of food protein by 1.3 kg. The calculation of the data on the conversion of protein into food protein showed that in the control group this indicator is 5%, and in the experimental group it was 6.2%. The yield of dietary protein in the control group was 40.4 g, in the experimental group – 52.8 g. Thus, the calculation of bioconversion showed that the animals of the experimental groups, which additionally consumed Hongurin zeolite and Kempendyai salt, had a higher ability to transfer nutrients and feed energy into meat products. The indicators of economic efficiency per 100 heads of fattening bulls of the Kalmyk breed are: profitability – 122.53%, cost price 1132 thousand rubles, profit – 1,388 thousand rubles, profit – 1.23 rubles per 1 ruble costs. The efficiency of beef production at a specialized feedlot increases by 22.53%.

The article is devoted to preventive measures to eliminate the problem of dysmicroelementosis in order to increase the productivity of young sheep. The article presents the results of studies of the influence of feeding rations on the growth and development of young sheep of the Edilbaev breed, on the level of their meat productivity and the qualitative characteristics of biologically fortified lamb. Feed additives based on Yoddar-Zn and DAFS-25 were added to the main ration of lambs at the age of four months, once a day, being added into a fodder mixture with concentrates. For the experiment the herd of lambs was divided to four groups of 25 heads each.The changes in live weight at the age of four, five, six and seven months were analyzed, and it was found that at the age of seven months, the absolute average weight gain in the experimental groups varied from 3.45 kg to 4.49 kg, in the control group it was 3.1 kg, while the largest live weight gain was recorded in group III which received both feed additives based on Yoddar-Zn and DAFS-25.There were no significant differences in the parameters of body measurements, with the exception of group III, where the chest circumference increased by 7.2%, and the height of a lamb at the withers increased in average by 8.1%. It was found that group III had the highest meat density coefficient, equal to 3.9, and the cross-sectional area of m. Longissimus dorsi was equal to 13.61 cm2. It was noted that the amount of free amino acids of the lamb group III is 18.8% higher than the meat of the control group. The lamb obtained from the animals of the experimental groups showed a higher protein content and less fat. The ratio of water to protein in all samples was slightly higher than 3.7, which corresponds to the Federa number for meat raw materials. Enriching the rations of the Edilbaevskoy sheep with feed additives Yoddar-Zn and DAFS-25 promotes the stimulation of growth and development of animals, increases the productivity and nutritional value of lamb.

Mineral Feed Additives

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

The studies were carried out on the basis of the SCHPK Soloyun Megino-Kangalassky region. The experiment was organized on Kalmyk gobies fed from 17 to 18 months of age. For the experiments, 2 groups of animals were formed, which were divided into control and experimental groups. The control group consumed the main diet, the experimental group additionally consumed 200 g of Suntarsky zeolite per head. The main diet of animals by structure consisted of meadow hay 46%, haylage – 22% and mixed fodder 32% or 11.95 ECU per day. During the experiment, the live weight of the animals was almost identical. At the end of fattening, the animals of the control group yielded to the bulls of the experimental group by 3.5%. It was found that the gobies of the experimental group had higher indicators of meat productivity, which affected bioconversion. The analysis showed that the control group of bulls yielded to the experimental group in terms of pulp by 26.9%, in the deposition of food protein by 13.6%. The conversion rate of protein into food protein in the control group was 12.0%, and in the experimental group the indicator was 21.3%. The yield of dietary protein in the control group was 8.08 g, which is 33.6% less than in the experimental group. Thus, the calculation of bioconversion showed that the animals of the experimental groups, which additionally consumed Suntarsky zeolite, had a higher ability to transform nutrients and feed energy into meat products.

Three experiments were carried out to improve the meat productivity of pigs of Large White (LW) breed of russian selection by different variants of crossing with the Yorkshire (Y) breed of canadian selection. There were no significant differences between the groups in terms of reproductive qualities. Two-breed pigs (LW x Y) grew more intensively and the live weight of the piglet at the 30 days was 8,7 kg, which is higher than in the other groups with a significant difference (P <0,05). When the live weight of 100 kg was reached, the вackfat thickness of the fat over 6-7 thoracic vertebrae was 26,3 mm compared to 30,7 mm in purebred pigs of the LW of the breed (P <0,001), the area of the muscular eye was respectively 45,1 cm 2 and 30,6 cm 2 (P <0,001). In the fourth generation of reproductive and absorbent crossing of pigs of LW and Y of breeds, the thickness of the fat on the carcasses of pigs was 21,2 mm (Р < 0.001), which is 30-39 % less than for the LW carcasses, the area of the muscular eye was 44 mm. In three-breed hybrids (LW x D) x L, the age of reaching 100kg was less by 12,5 days (P <0,01), the thickness of the fat was 23,6 mm, that is, it was 11,4 mm less (P < 0,001) in comparison with the control group. The replacement pigs obtained from the absorbent crossing (LW x Y) x Y showed the best results for the вackfat thickness - 19,2 mm, but they were inferior to the purebred Y (13,0 mm) (P <0,001). In the sows of this combination, 11,6 piglets were born alive, the number of piglets at weaning was 10,6, the weight of the nest in the 30-day was 78,7 kg. Differences in the frequency of occurrence of certain antigenic factors of blood in animals of different combinations of breeds are revealed. In animals that have the EAE allele edf, a higher growth rate is revealed, but thicker the backfat.

The aim of the research was to establish quantitative and qualitative indicators of meat productivity of Simmental bull calves of various constitutional types when raised using the technology of beef cattle breeding. The maximum growth rate and the highest yield of meat products were obtained from Simmental bulls of the meat and dairy type when they were raised and fed according to the technology of beef cattle breeding. Receiving from the mothers for 205 days of the sucking period more fatty milk, they gave 1250 g of gain per day and reached 289.7 kg of live weight by the cut. Having retained a high growth rate in the future, they at the final fattening gave 1321 g of gain per day and at 20 months the live weight was 659.3 kg. The superiority of Simmentals over analogues was natural by 3.4–13.3% by weight of the steamed carcass, by 0.4–1.8% in slaughter yield, by 1.4–11.1 kg in terms of the amount of pulp in the carcass and pulp per bones by 0.1–0.3 kg, protein in meat by 0.12; 1.19; 2.59 kg and the amount of energy in the pulp by 0.14; 0.44; 1.75 MJ. Simmental bulls of the meat and dairy type also have a high ability to transform protein and feed energy into protein and energy from the pulp of the carcass.
