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.

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.

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.

Among breeds of sheep meat-greasy directions productivity one of the prospective is edilbaevskoy breed. Due to the high maturing-STI, meat productivity and adaptability to arid conditions edilbaevskoy sheep are the most competitive. Young sheep are characterized by high slaughter qualities, especially lambs, slaughtered at an early age. This makes it possible to use them to produce high-quality lamb (lamb). The article analyzes the regularities of growth and development of young edilbaevskoy breed, it is established that the chemical composition of mutton affect the breed, age, sex, fatness, conditions of co-holding. With the age of animals at slaughter yield increases. Thus, the increase in slaughter yield in the period from 2 to 4 months of age was 2.9%, from 4 to 7 months of age-was 4.5%, from 7 to 10 months of age – was 6.7%, from 10 to one year of age-the increase was 1.6%. And for the entire period of cultivation from birth to one year of age - the increase in slaughter yield was 10.7%.A positive correlation was established between the pre-slaughter live weight of animals with total protein in blood serum at 4-month age it was 0.54, and at 7-month - 0.51. Studies have found that the strongest correlation with a high level of reliability (P>0.99) is between total protein, albumins and pre-slaughter live weight at 4 months of age. A globulin fraction of proteins has no significant correlation with the live weight of rams in different periods of growth (P>0.99). Consequently, with increasing concentration of total protein in serum increases pre-slaughter live weight. Thus, in order to obtain mutton, complete in biochemical and morphological composition and in high demand on the market, it is recommended to slaughter sheep of the edilbaevsky breed at the age of 4 months when they reach a live weight of at least 40 kg and a carcass weight of at least 16 kg.

AbstractFor the first time, the genetic structure of sheep breeds (Ascanian Fine-Fleeced, Ascanian Meat-and-Wool, AND Ascanian Karakul) and the hybrid Ascanian Fine-Fleeced × Texel was studied for structural gene variants: growth hormone, calpastatin, myostatin, and Booroola bone morphogenetic protein. In all studied groups, sheep were characterised by polymorphism of two loci, growth hormone and calpastatin. Two genotypes (A/A, A/B) represent genes of growth hormone structure, and three (M/M, M/N, N/N) represent genes of calpastatin structure. Other genes are in a monomorphic state. Analysis of the genetic relationships between the studied gene pools showed that there was a definite relationship between productivity of sheep herds and their molecular genetic parameters. Thus, the frequencies of individual genotypes and alleles change in the direction from Fine-Fleeced animals to sheep bred for meat productivity. For example, the heterozygous genotype A/B proportion of growth hormone gene increases in this direction from 0% to 38.2%, and allele A from 0.083 to 0.191. The live weight of Fine-Fleeced lambs with geno-type A/B at birth was 4.5 kg, and with homozygous genotype A/A — 4.9 kg (p < 0.001). This difference is genetically related to the meat productivity of sheep. A similar relationship was established for young Ascanian Karakul sheep. According to the distribution of polymorphic loci variants, the gene pools of Ascanian Meat-and-Wool breed and cross-bred animals are most similar closest among themselves, which is explained by the same direction of their productivity. At the same time, all populations are in genetic equilibrium according to Hardy-Weinberg equations, which indicates a high level of their consolidation. Sheep, which have the A/A homozygote of the gene growth hormone, have increased body weight.

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%.

Проблема и цель. Цель исследований – установить генотипические различия по убойным показателям чистопородных и помесных телок, полученных от скрещивания красной степной и голштинской пород, для более широкого использования эффекта гетерозиса в целях увеличения мясной продуктивности. Методология. Для проведения исследования были сформированы 3 группы телочек по 15 голов в каждой: I – красная степная порода, II – ½ голштин х ½ красная степная,III – ¾ голштин х¼ красная степная. По результатам контрольного убоя телок были определены убойные качества и морфологический состав. Качество полученной мясной продукции устанавливали путем определения морфологического состава полутуши и расчета полученного индекса мясности, соотношения съедобных и несъедобных частей туши, выхода мякоти на 100 кг предубойной живой массы. Результаты. Результаты исследований показали, что вследствие проявления эффекта скрещивания помесные телки превосходили чистопородных сверстниц по массе полутуши на 10,9 кг (12,0 %, Р<0,001) и 3,9 кг (4,3 %, Р<0,001), тогда как помеси 2-го поколения несколько уступали помесям 1-го поколения на 7,0 кг (7,4 %, Р<0,01). Неодинаковый выход мякоти у телок разных генотипов был обусловлен межгрупповыми различиями по массе полутуши. Было установлено, что помеси 1-го поколения превосходили по абсолютной массе мякоти телок красной степной породы на 9,3 кг (13,1 %, Р<0,001), а также по относительной – на 0,8 %, а помесей 2-го поколения, соответственно, на 6,0 кг (8,1 %, Р<0,01) и 0,5 %. В свою очередь, помеси 2-го поколения превосходили своих чистопородных сверстниц по изучаемым показателям на 3,3 кг (4,7 %, Р<0,05) и 0,3 % соответственно. Заключение. В результате исследований было установлено положительное влияние скрещивания на убойные показатели и качество мясной продукции. Problem and purpose. The aim of the research is to establish genotypic diferences in the slaughter parameters of purebred and crossbred heifers obtained from crossing red steppe and Holstein breeds, for a wider use of the heterosis efect in order to increase meat productivity. Methodology. To conduct the study, 3 groups of heifers were formed with 15 heads each: I – red steppe breed, II – ½ Holstein x ½ red steppe, III - ¾ Holstein x ¼ red steppe. According to the results of the control slaughter of heifers, the slaughter qualities and morphological composition were determined. The quality of the obtained meat products was determined by examining the morphological composition of the half-carcass and calculating the resulting meat content index, the ratio of edible and inedible parts of the carcass, the yield of meat per 100 kg of pre-slaughter live weight. Results. The results of the research showed that due to the efect of crossbreeding, crossbred heifers outnumbered purebred peers by 10.9 kg (12.0 %, P<0.001) and 3.9 kg (4.3 %, P<0.001), while crossbreeds of the 2nd generation were slightly inferior to crossbreeds of the 1st generation by 7.0 kg (7.4 %, P<0.01). The uneven yield of meat in heifers of diferent genotypes was due to intergroup diferences in the mass of the half-carcass. It was found that hybrids of the 1st generation surpassed red steppe breed heifers by the absolute mass of meat by 9.3 kg (13.1 %, P<0.001), and relative – 0.8 %, and hybrids of the 2nd generation, respectively, 6.0 kg (8.1 percent, P<0.01) and 0.5 %. In turn, crossbreeds of the 2nd generation exceeded their purebred peers in the studied indicators by 3.3 kg (4.7 %, P<0.05) and 0.3%, respectively. Conclusion. As a result of the research, a positive efect of crossbreeding on slaughter indicators and the quality of meat products was established.

Nutrients Digestibility

Feeding is the main condition for high productivity of ducks. It provides the need for metabolizable energy and nutrients according to modern standards. Ducks have an increased need for arginine, histidine, tryptophan, glycine, threonine and valine, therefore much attention is paid to the amino acid composition of feed in normalizing feeding. It is also important to consider the level of digestibility of the proposed feed. The feed nutrients digestibility depends on various factors and therefore varies considerably.Optimal ratios of carbohydrates, proteins, fats, etc. in the diet contribute to a high level of digestibility. The level of fiber and protein significantly affects the digestibility of nutrients in the feed. Increasing the amount of fiber (especially rich in lignin) reduces the digestibility of fiber and other nutrients. Essential influence on the nutrients digestibility is caused by the available protein content in the feed and its ratio with carbohydrates and fats. In this regard, the protein ratio of feed is determined. The protein ratio shows how many parts of digested nitrogen-free nutrients account for each part of digested protein.In addition, the feed preparation for feeding has a positive effect on their digestibility (moisturizing, enriching, grinding, steaming and others). The nutrients digestibility is also affected by different levels of macro-, micronutrients and vitamins in the feed. Increasing the feed nutrients digestibility is an important factor in reducing their costs, the cost of livestock products and improving the economic efficiency of the industry. Young ducks are characterized by precocity and high growth rate. At the age of 7 weeks, the live weight of hybrid young ducks is 3.2 – 3.4 kg, and during this period the initial weight increases more than 60 times at a feed consumption per 1 kg gain of 2.8 - 3.0 kg and average daily gain 64 - 68 g.The positive effect of the use of the developed vitamin-mineral premix in the compound feed composition on the meat productivity of “Blagovarsky” cross ducks has been determined. It was determined that from the third week of growing the live weight of young ducks of the experimental group was higher of analogues of the control group for 3,2 %. Analysis the main indicators of young ducks productivity showed that the bird of the experimental group exceeded analogues in the following periods of growth: 0 - 7 days, 15 - 21 days, 29 - 35 days, 36 - 42 days, 43 - 49 days.Survival rate of young ducks was at a high level in the range of 97 – 99.5 % for the entire period of growing in both groups. Starting from the 4th week of growing, the survival rate decreased slightly in the control group and amounted to 99.1, which is 0,2 % less than in the experimental group. The increased concentration of premix in the compound feed for the young ducks of the experimental group help to improve their slaughter qualities in comparison with the control group.

The use of molecular genetic markers for productivity is one of the modern approaches in breeding beef cattle. The article presents the results of the studies on the influence of genotypes by the calpain (CAPN1) and growth hormone (GH) genes on live weight, fatty acid composition of blood plasma, quantitative and qualitative indicators of meat of young cattle of Kazakh white-headed breed. It was established that animals of the homozygous geno-types СС–CAPN1 and VV-GH had a larger live weight and its average daily gain on the 240th and 365th days. Their superiority over the GG and LL genotypes was 13.8% (P<0.05) and 6.9%; 14.6% (P<0.05) and 6.9%, respectively. The carriers of the desirable alleles in the homozygous state had the sum of unsaturated fatty acids higher by 6.3% and 7.1%, respectively, than the young bulls, in which genotypes they were absent. The predominance of unsaturated fatty acids over saturated fatty acids also determined lower values of lipid me-tabolism direction index (0.92 and 1.00) in the animals with the desirable genotype. Muscle tissue of animals of the СС and VV genotypes was characterized by a higher level of protein, fat by 0.28–2.13 abs. per cent, energy value, and the quantity of muscle fibers with a smaller diameter per unit area compared to the GG and LL genotypes by on average 8.7% and 25.5% (P<0.01). Due to the greater number of interfiber fat inclusions, muscle tissue of the desirable genotypes received higher marbling scores. The obtained data testify to the prospects of replication of animals, which genotype has the desirable alleles for further improvement of traits of meat productivity of Kazakh white-headed breed.

The article presents the data obtained as a result of carrying by employees of the Research Institute of sheep and goat breeding, a branch of the FSBSI "North Caucasus FARC", the scientific and economic experience to study the efficiency of a new fodder additive "Organic" on the productive and physiological indices of bull-calves during the completion of growing in the conditions of the farm "Pata" agricultural enterprise in the Karachay-Cherkessia Republic. The statement of the experience and all researches were carried out according to generally accepted methods. In the course of the experiment, the following indices were studied: the chemical compound of forages, the dynamics of a live weight gain in the experimental stock, hematological parameters, control slaughter data, economic indices. Completed researches have shown positive result from the use of the fodder additive "Organic" in bull-calves diets: an increase in the average daily gain of live weight by 25%, a slaughter yield by 1% and a high level of profitability – 27%. Thus, the additional introduction of "Organic" in a diet of young horned cattle in the 2nd experimental group promoted more intensive metabolism, stabilization of a physiological state, increase in productivity and, as a consequence, profitability of beef production. Researches in this direction reveal the latent fodder reserves promoting increase in the productivity of agricultural animals.

Statistical data of livestock for 30 years is reflected in the article. Author used the materials of the state veterinary reporting. A comparative analysis of the number, incidence and death rate of adult animals and young cattle for two five-year periods (2001-2005 and 2014-2018). the data of the analysis of veterinary statistical reports for 2018 on the specific weight of the large horned cattle and age dynamics of calves in farms of the Vologda region are shown. A significant decrease in livestock of the large horned cattle by 56.3% (from 1990 to 2018) is shown in the analysis of the data. Over the five years 2014-2018, there was a decrease in the number of the large horned cattle by 31.3%, the birth rate of calves - by 26.2%, and the incidence of calves - by 12.3% and the mortality rate decreased by 3.3%. Despite the decline in the number of livestock, in 2018 there is a high incidence of animal diseases (49.6%). The highest incidence rate was observed among calves under 10 days of age 43.3%, 31.7% - from 11 to 30 days, 15.8% - from one to three months, 6.5% - from three to six months and 2.7% - from 6 to 12 months. Of the total number of sick calves in 2018, 63.2% had gastrointestinal diseases, and death for this reason is 49.6% of the total number of victims. Respiratory diseases affect 21.8% of young animals, and death due to respiratory diseases is 18.2%. Analysis of statistical data showed that, despite the complex of veterinary and sanitary measures, the incidence and death of calves remain at a high level. This can be explained by delayed diagnosis and low therapeutic effectiveness in gastrointestinal and respiratory diseases of cattle.
