The article presents comparative studies of the meat productivity of geese of the Lindovskaya breed when zeolite and nanostructured zeolite feed additives are introduced into their diets. It was shown that the use of zeolite contributed to an increase in the live weight of geese by 4.0 %, the use of different doses of nanostructured zeolite led to an increase by 6.2–10.2 % (P≤0.05), in comparison with control analogues. When using zeolite in meat, the content of zinc and copper salts decreased by 28.0 and 13.1 %. The introduction of nanostructured zeolite into the diet led to a decrease in zinc content by 27.5–31.3 % and that of copper by 27.1–48.6 % compared with the control. The meat of birds of all groups corresponded to hygienic quality requirements for the content of chemical elements.

Currently, the existing literature sources on the use of feed additives “Tetra+” and “Glimalask” do not fully reflect the data on the comparative study of their infl uence on the physiological state, meat productivity and pork quality of fattened young pigs. Under the conditions of the Lower Volga region comprehensive researches were carried out in a comparative aspect to improve meat productivity and pork quality through the use of feed additives “Tetra+” and “Glimalask” in the diets of young pigs on fattening. The purpose of the work was to increase the productive and pork quality of young pigs on fattening due to the use of feed additives “Tetra+” and “Glimalask” in their diets. The research was carried out in the period from 2012 to 2019. The experimental part of the work took place under the conditions of the stud farm named after Lenin in the Surovikinsky district in the Volgograd region. The object of research was young pigs of Large White breed. The positive influence of feed additives on the digestibility and use of nutrients in diets, meat productivity and pork quality, physiological indicators and economic effectiveness of pork production has been proven. It has been found that the level of profi tability of pork production was higher in the experimental groups in comparison with the control group by 5,03 and 4,48 %, respectively. At the same time the highest effectiveness has been obtained from the animals of the 1st experimental group, which received the feed additive “Tetra+” in the diet, which allowed to increase the live weight gain by 6,74 %, the level of profitability by 5,03 %. Thus, the feed additive “Tetra+” was the most effective.

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 purpose of the work was to study and identify the main factors aff ecting the quantity and quality of beef produced and sold in the Southern Federal district. A comparative assessment of the growth, development, formation of meat productivity and quality of beef of young animals of beef, dual and dairy breeds with stall-pasture technology and intensive rearing in the industrial complex. Experimental studies have been carried out in farms in the Rostov region. The object of research was cows with calves of Kalmyk, Hereford, Aberdeen-Angus, Russian komolaya, Kazakh White-headed breeds, as well as young animals of the same breeds, in addition, Black-and-White and Swiss breeds. Removable live weight in Hereford steers at 18 months of age was 658,0 kg, and Aberdeen-Angus – 655,2 kg. Domestic steers of Kalmyk were 41–44 kg lower in live weight than their herdmates of two imported breeds. However, with intensive rearing at 18 months of age, steers of Kalmyk breed had a removable live weight of more than 613,7 kg and a carcass weight of 326 kg. The yield of hot carcass was 55,4 %, and the slaughter yield was 58,89 %, which was only 1–2 % lower than the world’s leading beef breeds. It has been found when analyzing the results of boning the half-carcasses of experimental steers that the biggest weight of half-carcasses and the content of muscle and fat tissue in them in absolute terms were in Hereford steers. Steers of Kalmyk breed took the third place in terms of weight of large-sized semi–fi nished products and signifi cantly lost to Aberdeen-Angus herdmates by 7,3 kg or 6,5 %, and Hereford steers by 9,2 kg or 8,3 %. The results obtained prove the expediency of using stallpasture technology in the dry-steppe zone of the Southern Federal district when rearing young animals for beef up to 350–400 kg live weight at 15 months of age and its subsequent intensive rearing under industrial technology, in order to obtain the live weight of more than 570 kg and produce cost-eff ective beef.

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.

Established that the largest distribution combined with feed additives which include a number of biologically active substances. As an alternative to antibiotics, the use of which recently banned their production and significantly reduced feeding system is used four groups of drugs, enzymes, probiotics, prebiotics and аcidifiers. The largest number of feed additives used in poultry feed. Therefore, to improve the consumption and use of feed efficiency, obtaining maximum animal performance ensured a high level of balanced nutrition using the same enzyme–probiotic supplements. It is to include such feed additives «Proenzym» which consists of live bacteria genus Bacillus subtilis and an enzyme tsellyulaza. What prevents gastrointestinal diseases, improves digestion and absorption of essential nutrients intake. Therefore, the aim was to study the effect of feeding different doses feed additive «Proenzym» in the quail Full–feed and its impact on productivity and internal organs. For the experiment selected 200 day old Estonian quail breed. Of these, the principle of analogues formed four groups of 50 goals each. The duration of the experiment – 56 days. The first (control) group during the entire experiment received a basic diet, and quail research groups in addition to the basic diet fed different doses of feed additives. For the effects of various doses feed additive had a positive effect on live weight quails in 42 and 49–day age. Yes, most live weight at the end of the experiment were females and males second experimental group 10.8% and 8.3%, which in addition to full–feed introduced minimum dose «Proenzym» The introduction of the new maximum amount of feed factor had a significant impact on the weight of internal organs, quails second group for the actions of study drug increased the mass of the lungs and liver, respectively, 0.6 g and 3.4 g, and gallbladder in 4 experimental group 0.16 g. Therefore, we can conclude that the diets of quails best was the maximum amount of feed additive.

The Republic

One of the main branches of agriculture in the Republic of Sakha (Yakutia) is productive horse breeding. In this regard, we can use the valuable raw materials that the horse gives due to its high adaptability to local conditions. The development of productive horse breeding in particular dairy horse breeding under the conditions of the Republic of Sakha (Yakutia) would allow providing the population with natural, dietary food and more efficient use of land resources. The purpose of the work is to study the effect of zeolite and zeolite-sapropel feed additives in the ration of mares of Megezhek breed on the milk productivity and quality of kumiss under the conditions of Central Yakutia. Two scientific and economic experiments have been carried out where the influence of zeolite from the Suntar deposit (experiment 1) and zeolite-sapropel feed additives (experiment 2) on the milk productivity and physiological parameters of mares of Megezhek breed has been studied. The optimal doses of the effect of zeolite and zeolite-sapropel feed additives on the profi tability of kumiss production have been determined. It has been found in the first scientific and economic experiment that when adding 0,4 g of zeolite per 1 kg of live weight to the daily ration of lactating mares the level of profi tability of milk production increased to 20,4 %, and when adding 0,5 g per 1 kg of live weight the profi tability index increased to 21,5 %, compared to 13,7 % in the control group. In the second scientific and economic experiment the infl uence of the zeolite-sapropel feed additive on the intensity of digestion and assimilation of nutrients in the mares’ rations has been determined. The analysis of the experimental data indicates a high economic efficiency of using zeolite-sapropel feed additive in the 2nd and 3rd experimental groups of mares, where the level of profi tability of production was equal to 27,34 and 32,33 %, respectively, compared to 16,09 % in the control group.

The purpose of research is increase of beef productivity and beef quality of Simmental calves at introduc-tion in a diet of feeding different doses of the drug Vetosporin suspension. Of the half-yearly animals, 40 males were selected and formed into group IV for the experiment. The differences were only in feeding. The young were fed the studied additive Vetosporin suspension. In this case, the supplement was an addi-tion to the basic diet of animals of the experimental II-IV groups. The volume of the additive added was 0.1; 1.0; and 2 ml per 10 kg of live weight, respectively. Control group I, consumed exclusively a diet that does not contain an additive. Based on the results of the experiment at the age of 18 months. The prevalence of bulls of the experimental live weight over peers was observed, which was 4.4-25.3 kg (0.78-4.67%). The study of the studied indicators after control slaughter in the context of groups showed the superiority of bulls of experimental groups in all the periods studied. It is established that at the age of 15 months. The size of the removable live weight of the youngest of the control group was less by 8.0-19.7 kg (1.75-4.29%) than in the animals of the test groups. In this case, the leading position was occupied by the youngest of group III, the prevalence of which was 0.7-11.7 (0.14 -2.51%). It should be noted that after 3 months a simi-lar picture of the distribution of the studied quantities was observed. As for the output of carcass, we can note the following. Outsider among the animals of the experimental groups was the control group. So the bulls of group I were inferior to those who received the additive by 0.7-1.3%. At 18 months, as well as at 15 months, the dominant position was occupied by gobies of experimental groups. It should be noted that among the animals of the experimental groups the leading place was occupied by the bulls receiving the feed additive in a dose of 1.0 ml per 10 kg of live weight, that is, the youngest of the III group.

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.
