The aim of this study is to investigate the effects of adding different doses of boric acid (H3BO3) to the mixed feed of Japanese quail (Coturnix coturnix Japonica) on fattening performance, carcass and bone properties. For this purpose, a total of 96 quails aged 15 days were balanced according to their live weight and sex, and 4 trials were randomly divided into groups. Each group is composed of 4 repetitions. Trial groups; the control group (C) given mixed feed, the group with 100 mg / kg boric acid (BA) added to the feed BA100; 300 mg / kg boric acid was added to the feed group BA300 and 500 mg / kg boric acid added to the feed group BA500. Data for the fattening period were followed for 15-43 days. At the end of the experiment, carcass and bone characteristics of 8 quails (two quails from each repeat) from each group were examined. The live weight and live weight gain of the quail was similar among the experimental groups (P>0.05). Adding boric acid to feed did not affect feed consumption and feed utilization rate (P>0.05). While the breast rate decreased significantly due to the increasing levels of boric acid addition (P<0.01), an increase in the back and neck ratio was detected (P <0.05). The highest thigh ratio was found in BA300 and BA500 groups (P<0.05). Carcass yield, wing and liver rates were similar between the groups (P>0.05). Tibia and femur weights and dimensions were not affected by the addition of boric acid (P>0.05). The highest femoral ash level was determined in the BA300 group (P=0.05). The tibia ash level increased from the Control group towards BA300 and was the lowest in the BA500 group (P<0.05). As a result, while the addition of boric acid to the feed cannot be affected to the fattening performance of quail, its effect on carcass and bone properties has been found significant.

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.

According to the experiment, the productive effect of different amounts of grain of the triticale of Harroz variety in feed for the reproductive indices of feeding rabbits was established. According to the tasks assigned, five groups of nursing rabbits were selected and formed according to the principle of analogues. To feed the experimental nursing rabbits, a full granulated mixed feed was used in the structure of which there was a different content of triticale grain: II research group – 10.0%, III, IV and V research groups - 20.0%, 30.0% and 40.0% respectively . Nursing rabbits of the 1st control group were fed full-fat mixed fodders, which were balanced for the main nutrients, but did not contain triticale grain. In the study of the multiplicity of feeding rabbits with different contents of crushed grain of the triticale of the Harroz variety, it was higher in the 3rd and 4th experimental groups (in the ration of 20 and 30% of the crushed grain of triticale) with an index of 8.0–8.2 heads (P < 0.05). The large-fruited index predominated in the nursing rabbits of the 4th experimental group and amounted to 65 g; in the 1st, 2nd, 3rd and 5th groups it was 62, 63, 64, and 61g. The amount of milk of nursing rabbits is an indicator that positively correlates with fecundity, the weight of rabbits at birth (large-fruited), the preservation of the nest. Milk index was also the best in nursing rabbits of the 4th group and amounted to 2.83 kg, which is 0.09–0.24 kg more than in all other groups (P < 0.01). By the number of rabbits with weaning at 35 days, the fourth group of nursing rabbits predominated, this index was 7.1 g. The average live weight of one head during separation was higher by 40–50 g in the 3rd and 4th test groups compared to the first control group and amounted to 0.75 and 0.76 kg (P < 0.05). According to preliminary indications, the best nest weight in weaning during 35 days was the nursing rabbits of the 4th group – 5.36 kg, which is 0.47 kg higher than the control (P < 0.05). The highest percentage of conservation of rabbits before weaning at 35-day-old age was observed in groups 3, 4 and 5, and was at the level of 94.59; 93.42; 97.1%. It was found that the structure of the ration of nursing rabbits with a content of crushed grain of triticale of Harroz 20, 30 and 40% was significantly influenced the preservation of the nest. The index – the index of the reproductive qualities of feeding rabbits (IVKK), based on the indicators of large-fruited, milk and number of rabbits with weaning (35 days) was higher in feeding rabbits of 3rd and 4th groups and amounted to 126.4 and 128.8. The maximum reproductive indices of feeding rabbits provided a structural content in the diet of 30% of the crushed grain of the triticale of the Harroz variety (the fourth research group). The ration (30% of the triticale crushed grain) ensured the growth of the multiplicity by 8.5%, the size of the fetus by 5%, the milkness of the rabbits by 9%, the weight of the nest at weaning at 35 days old by 9.6%, and the complex index of IVKK by 6.5%.

The paper highlights the research conducted in order to assess the effect of different doses of thyme extract on the productive properties and livability of broiler chickens. The experiment was conducted at a broiler poultry farm with a closed production cycle; the experiment assumed the control group and 5 experimental groups where each group contained 37 broilers at floor housing. The broilers of the 1st experimental group were fed with the extract of medicinal plant thyme dosed 2 mg/kg; broilers of the 2nd group received thyme extract dosed 4 mg/kg; 3rd group of broilers – 6 mg/kg, 4th group -8 mg/kg, and the dosage of the thyme extract was 10 mg/kg for broilers in the 5th experimental group. The authors controlled the live weight of broilers in each group by means of individual weighing every 7 days. Using this data the researchers calculated average daily body weight gain, absolute and relative gain; feed consumption was daily calculated. Feed consumption became the basis for calculating feed costs per a kilo of live weight gain. The authors recorded the number of daily fallen chickens. The data on poultry loss was the basis for calculating poultry livability. In order to assess production efficiency, the European productivity index was calculated. The research results indicate the efficiency of thyme extract application in different doses when feeding the broiler. Application of thyme extract in feeding meat poultry allowed to increase productive properties of broilers from experimental groups from 2.3 to 4.7%, reduce feed costs per a kilo by 1.1-8.1%, increase poultry livability on 2.7-8.1% and increase the European productivity index in the experimental groups on 0.2 21.3%.

The article presents data on a scientific experiment conducted on quails of the Japanese breed. Data on the influence of the prebiotic drug «BioAxel» on the physiological parameters of quails have been established. The dynamics of the live weight of quails when feeding different dosages of the drug is estimated. In the experiment, the positive effect of different doses of the feed additive «BioAxel» on the average daily and gross growth of experimental birds (by 8,2–16,5% compared to the control) was established. The most effective method was feeding part of the BioAxel (5% of the feed weight) plus another part (4%) with water. A comprehensive veterinary and sanitary examination of quail slaughter products was also carried out when using the prebiotic drug «BioAxel»in the diet. It was found that this drug does not have a negative effect on the quality of meat. At the same time, the indicators of biological safety are within the limits of the norm established by current regulatory documents. In terms of nutritional value, the meat of quails raised with the use of the prebiotic drug «BioAxel» exceeds the meat of quails from the control group. The content of essential amino acids significantly increased in poultry meat of the experimental groups, and the total biological value in the test with Tetrahymena pyriformis exceeded the control parameters.

The effectiveness and high degree of biological effect of dead bees extract in medium doses on the nature and degree of morphofunctional rearrangements in the immunocompetent structures of the central and peripheral immune organs and immunocytological reactions in them have been established. A scientifically based scheme for the use of dead bees extract is proposed to improve the livability of livestock, increase live weight and improve the biochemical indicators of the quality of quail meat. Dead bees extract in low and especially in medium doses increase the production of the red bone marrow cells of the granular germ of white blood cells by 22,2 and 25,6 %, lymphoid cells by 4,7 and 6,9 %, erythroid germ by 2,3 and 11,0 %. Under the action of dead bees extract in the Fabricius bag quail strengthens the processes of maturation and differentiation of B-lymphocytes, which is manifested by extension immunocompetent cortical area in the 2nd and 3rd experimental groups (30 and 60 days of experiment by 10,4 and 22,1 % and 12,3 and 24,3 %, respectively), a reduction in brain area. The increase in the weight of the Fabricius bag (despite its general involution) in the 2nd and 3rd experimental groups on 30 and 60 days was 1,24 and 1,47, 2,59 and 3,0 times, respectively. In the thymus of quails under the influence of low and medium doses of dead bees extract the intensifi cation of maturation and differentiation of T-lymphocytes, resulting in the expansion of the cortical substance on 30, 60 and 90 days of 1,55 and 1,62, 1,42 and 1,73, 1,61 and 1,95 times, respectively, against the background of the depletion of brain matter, in excess of the thymus weight (with its expressed total involution) by 1,32 and 1,42, by 1,38 and 1,5, by 1,24 and 1,34 times, respectively. Dead bees extract activates the processes of antibody formation, increasing the immunological activity of the spleen in the form of expansion of the area of lymph nodes without light centers in the 2nd, 3rd and 4th experimental groups by 1,39, 1,83 and 1,5 times, respectively, and with light centers by 1,57, 1,79 and 1,19 times (B-zone). It increases the area of the perivascular lymphoid coupling (T-zone) by 1,5, 1,8 and 1,28 times, respectively, activates immunocytological reactions, increases the weight of the spleen of quails. The live weight of the males of the 2nd, 3rd and 4th experimental groups exceeded the control by 27,6, 31,8 and 18,9 g, and the females by 17,6, 27,7 and 9,9 g, respectively. The livability of livestock in the control group was 78,0 %, in the 2nd, 3rd and 4th experimental groups 89,0, 95,0 and 85,0 %, respectively.

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.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

The experiment has been carried out on a crossbred stock of young pigs in the period 2015–2017 under the conditions of JSC CHC “Krasnodonskoe” in the Ilovlinsky district in the Volgograd region. The purpose of the research was to study the effectiveness of the effect of the anti-stress drug Feed-Food Magic Antistress Mix in intensive pig rearing on the productive traits and quality of the products obtained, as well as the estimated economic indicators. In order to conduct a scientific and economic experiment at the age of 60 days young pigs were divided into 2 experimental groups (control and experimental) according to the principle of pair analogs. Each group contained 25 heads. The difference between the control and experimental groups was that the animals in the control group have received the main diet, and the experimental group has received the anti-stress drug Feed-Food Magic Antistress Mix in addition to the main diet. In the experimental group of pigs when this drug was administered in the age 180 days the live weight parameter was higher than in the control group by 1,55 kg. Clinical indicators of young pigs were within the physiological norm. The pre-slaughter weight in the experimental group has increased by 4,86 % compared to the control group. Due to the use of an anti-stress drug the slaughter weight of animals in the experimental group has increased by 6,69 %. In comparison with the control group the slaughter yield in the experimental group has increased by 1,18 %, in which this indicator was at the level of 67,62 %. The morphological composition of carcasses in animals of the experimental group was also improved. Meat yield has increased by 0,95 %. The yield of fat and bones has decreased by 0,59 and 0,36 %. The weight of internal organs was also superior in the experimental group of pigs. Due to the use of the anti-stress drug the level of profitability in the experimental group of animals has increased by 11,69 %.

The reliability of the results obtained in scientific and economic experiments on the study of the effectiveness of the use of various feed components, including biologically active substances in the rearing of broilers needs to be confi rmed in production conditions. The purpose of the research was to study the joint use of enzyme drugs and lecithin in the rearing of broiler chickens. The results of production experiment on the study of the effectiveness of the joint inclusion of enzyme drugs Sunzyme and Sunfyse 5000 as well as lecithin in the diet of broiler chickens of the cross Ross-308 have been presented in the article. Production tests have been carried out under the conditions of the breeding farm “Achkhoy– Martanovsky” in the Chechen Republic. The duration of the experiment was 45 days. For research on the principle of analog groups two groups have been formed: a control group and an experimental group of 1000 heads in each. The broilers of the control group have been fed compound feed prepared in accordance with the growing period and consisting mainly of grain components of local production. The broilers of the experimental group have been fed the same compound feed, but with the addition of two enzyme drugs Sanzyme and Sanfyse 5000 (100 g/t of feed) as well as lecithin (10 g/kg of feed). The results of the production experiment fully confi rmed the data obtained in the scientific and economic experiment. The positive effect of the joint use of the studied enzyme drugs and lecithin has been manifested in all the studied productive traits. In particular, the increase in live weight of broilers increased by 12,1 %, slaughter yield by 3,5 %, the yield of carcasses of the 1st category by 3,0 %. The main economic indicators also found their confirmation: feed consumption per unit of growth decreased by 11,7 %, additional profit was received in the amount of 27308,2 rubles, the level of profitability of broiler rearing increased by 18,4 %.

On Farm

It is well known that the growth rate of an animal depends on the level of feeding. However, the diets used in farms do not always meet the body’s needs for biologically active substances. In recent years numerous studies have been conducted to study the eff ect of natural and synthetic complex biologically active drugs on the productivity, metabolism of pigs and the quality of the products obtained. The imbalance or lack of certain nutrients in the diet reduces the productivity of animals, reduces the conversion of feed. The purpose of our research was to study the effect of the drug Permaite included in the diet of pigs on some indicators of the quality and safety of pork. Permaite is a standardized zeolite-containing trepel of the Chuvash Republic. Its chemical composition is (%): silicon oxide – 64,39, iron oxide – 3,25. aluminum oxide – 8,42, titanium oxide – 0,45, calcium oxide – 7,74, calcium carbonate – 14,7, magnesium oxide – 1,71, potassium oxide – 1,81, sodium oxide – 0,03, phosphorus pentoxide – 0,20 and other impurities – 11,9. Experimental studies have been conducted on 2 groups of pigs on rearing and subsequent fattening. Pigs of the experimental group have been received the main diet with the inclusion of the drug Permaite at a dose of 3 % to the dry matter of the main diet in the form of a fraction of 0,1–0,3 mm. The drug has been prescribed once a day in a mixture with compound feed for 60 days. The control group of pigs during this period was on farm diet without the inclusion of the drug. Upon reaching the live weight of 100–110 kg the pigs have been sent for slaughter. The results of the research allow us to conclude that the inclusion of the drug Permaite in the dose of 3 % to the dry matter of the main diet provides the increase in the nutritional, biological, energy value, technological properties and safety of pork.
