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%.

Modern pork production technologies are aimed at obtaining maximum productivity data, which are an indicator of the effectiveness of pig industry in general. The aim of the research was to develop a biotechnological method of increase of prolificacy of sows with 1 and 2 farrowing, using biologically active medicines of the neurotropic-metabolic action – Glyutam 1M and Nanovulin-BA. On the day of weaning, all the experimental sows were injected with vitamins Introvit in a dose of 10 ml/head. The sows in the research groups received Glutam 1M and Nanovulin-BA for three days in the morning in stern balls, which contained 100 grams of feed and 20 ml of medicine. The sows of the II and III experimental groups received Glutam 1M starting from the day of weaning. Nanovulin-BA was fed to the sows of the III and IV research groups at 0-2 day of sexual cycle. The females of the control group were fed by 20 ml of saline during these periods of reproductive cycle. In the II and III research groups the live weight of hypertrophous and normal piglets was bigger compared with the control one by 7.7%, 9.2% and 9.7%, 8.6% respectively. The weight of hypertrophous animals of the I group exceeded data of the control one within the error, while the weight of normal piglets was higher by 11.5%. The increase in live weight of hypertrophous and normal piglets of sows in the II and III research groups contributed to the significant increase of the total weight of newborn piglets by 26.3% and 26.3% (in comparison with the control group). In the I research group, it increased by 27.1%, mainly due to normal piglets’ weight and therefore was not likely. The influence of Glyutam 1M and Nanovulin-BA on the prolificacy of sows was analyzed, taking into account that the experimental groups were formed from sows with two different farrowing – 1 and 2. Live weight of the hypertrophous piglets of the sows from the I group after the 1 farrowing was higher by 8.8%, compared to animals which had 2 farrowing. Live weight of hypertrophous and normal piglets in both subgroups was almost at the same level, while the total weight of piglets from the animals with 2 farrowing was higher than from females with 1 farrowing by 10.7%. Total weight of newborn piglets from the sows in group III with 2 farrowing increased compared to the animals with 1 farrowing by 16.1%. Comparative analysis of the influence of sows’ age on live weight of piglets showed, that the live weight of normal piglets in the I experimental group with 2 farrowing was higher by 11% compared to the control one of the same age (with 2 farrowing). Total live weight of piglets in the I experimental group with 1 and 2 farrowing was higher by 23.0% and 26.8% compared to the control group of animals of the same age. In the II experimental group live weight of normal piglets from sows with 1 and 2 farrowing increased by 11% and 7.4% respectively in comparison with animals of the same age in the control group. Total live weight of newborn piglets in the II experimental group increased by 28.0% and 24.8% respectively compared to the animals of the same age of control group (1 and 2 farrowing). The live weight of hypertrophous piglets from experimental group III (2 farrowing) was higher by 15.1%. The injections of biologically active medicines during insemination of sows in the group III contributed to the increase of live weight of normal piglets (sows with 1 and 2 farrowing) compared with the control one by 11% and 8% respectively. In the III group of animals with 2 farrowing the total weight of newborn piglets increased significantly by 29.6% compared to control animals of the same age (with 2 farrowing). Analyzing live weight of hypertrophous piglets it should be noted, that in the control group of sows with 1 farrowing this category of piglets was absent. While control females with 2 farrowing and animals of the research group, regardless of their age, showed, that the live weight of hypertrophous piglets was almost at the same level. Comparative analysis between groups showed, that the live weight of hypertrophous and normal piglets in the I experimental group was higher in comparison with the control one by 14.1% and 11.5% respectively. Weight of hypertrophous piglets from females of the I experimental group was the same compared to the control one. While the weight of normal piglets increased by 10% compared to the control group. Injections of theneurotropic-metabolic medicines to the sows of the II and III research groups helped to increase the prolificacy by 15.1% and 9.2% and 12.2% and 9.9%. The live weight of normal piglets in the II and III research groups was higher by 8% and 9.2% respectively. Іn this way, the injections of biologically active medicine Glyutam 1M for 3 days after the weaning cause an increase in live weight of newborn piglets by 14.1%. Feeding females with Glyutam 1M and Nanovulin-BA at one time helped to increase live weight of piglets by 13%, and the injections of Nanovulin-BA only – by 11.8%. Injections of neurotropic-metabolic medicines with biologically active action on different schemes of their use cause the tendency to increase the live weight of both sexes embryos in the prenatal period up to 2 kg for sows of the 1 and 2 farrowing.

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 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.

One of the important conditions for the successful conduct of geese farming industry is normalized physiologically reasonable feeding birds that carried out by the use of complete feed and feed additives, including biologically active substances. Since days old, I (control) group of geese received during the research period, complete feed is made in terms of private enterprise «Orbita», II, III, IV and V (experimental) group received a complete feed with the addition of its composition of different doses of lecithin sunflower instead of a similar amount of soybean meal. At the beginning of the experiment live weight of geese had no significant differences in terms of research groups, indicating that similar selected poultry and averaged 116 – 118 grams. Since the first week of growing live weight of geese in experimental groups fed sunflower lecithin slightly increased. If, at the beginning it was not quite expressed, starting from the second week of growing this advantage becomes more significant. So, the live weight of geese at the age of two weeks in the control group was 1287 g, while the live weight of geese II, III, IV and V of experimental groups was higher by 1.4%, 4.3% (P < 0.01), 6.2% (P < 0.001) and 4.9% (P < 0.001), respectively. These differences observed between the experimental groups during the growing period. Thus, at the end of the first period of growth, namely four weeks of age, live weight of geese fourth experimental group was 3350 g, 8.0% (P < 0.001) higher relative to the control group by 5.6% compared to II experimental group, 2.8% (P < 0.01) III and 2.2% (P < 0.01) V research group. It should be noted that at the end of the second period, growing at the age of nine weeks goslings in control group matched the experimental group II on 2,3%, III – 5.1% (P <0.01), IV – 10.3% (P < 0.001) and V – 7.5% (P < 0.05), respectively. To study the anatomical and morphological structure of the experimental birds at the end of the scientific and economic experiment in the 60 days age were held control of slaughter. Our results indicate that different amounts of sunflower lecithin in diets of young geese during their growing meat differently affect their slaughter capacity. Table 3 shows that young geese feeding in the composition of animal feed sunflower lecithin has contributed to their live weight in experimental groups respectively 1.8%, 5.3%, 9.4% and 7.5% compared to the control group counterparts. For goose gut carcass weight preference geese in experimental group was respectively – 3.2%, 6.9%, 12.3% and 8.6%. The biggest muscle mass was observed in the experimental group IV geese and amounted to 1 895 g, that on 14.2% more muscle mass geese control group. The mass of muscle II, III and V of the research groups on the same indicator was higher by 3.0%, 7.7% and 9.2% in comparison with I control group. The use of sunflower lecithin in diets of young geese caused the increase in weight of internal fat. Thus this indicator preference experimental groups was – 5.7%, 15.4%, 25.1% and 18.3% according to analogue control. These changes have led to improved of meat and bone index. Thus, birds III, IV and V research groups preference for this indicator was 5.1%, 11.9% and 6.8% according to analogue controls. The indicator in poultry II experimental group was on par with the control group. Thus, putting in the diets of young geese sunflower lecithin positively affected the rate of growth of young geese slaughter their performance and made it possible to reduce the cost of feed per unit of growth. However, the best results were obtained when control weighing and slaughter, which is part of the feed was injected 0.4% sunflower lecithin.

One of the ways to increase meat resources is to improve the condition of livestock on farms in the Russian Federation. This is due to the fact that when the fatness of the animal increases, the meat yield in the carcass increases. The purpose of the researches was to establish the features of the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed. In order to achieve this purpose two groups of steers-analogs of Hereford breed (control and experimental) at the age of 6 months per 10 head in each have been formed. The time of the experiment was: the preparatory period of 22 days and the main one 275 days. Steers of the control group have received the main farm ration, and steers of the experimental group have received the main ration and feed protein additive Biovitel for 30 days with 10-days interval at the dose of 100 g per head during the sixth month. The results of researches on the infl uence of the feed protein additive Biovitel on the growth and development of steers of Hereford breed have been refl ected in the article. The addition of the feed additive Biovitel to the main ration of the experimental group of steers helped them to achieve a higher live weight and higher average daily gains under the same environments of feeding and housing in all age periods. By the end of the experiment (15 months) the experimental group of steers have reached the live weight of 430,2 kg, which was higher by 19,9 kg or 4,9 % compared to the control group of steers. In order to improve the quality of beef and increase its production more intensive rearing of steers of Hereford breed with the use of feed protein additive Biovitel has been justifi ed. The recommended dose is 100 g per head. This dosage allows you to achieve the average daily gain of 967,5 g and the average live weight of 430,2 kg by 15 months of age, reduce the prime cost and increase the profi tability of beef production.

The morbidity of newborn calves caused by enterotoxigenic staphylococci is associated with an increase in staphylococcal processes that are localized in the lizard of the cows and the carrier of the pathogen. Such cows, often with colostrum, transmit the pathogen and its toxins to newborn calves. According to the results of bacteriological studies, in the subclinical form of the mastitis with secretion of the dementia of the cows, Staph. aureus, staph. intermedius, staph. epidermidis, E. coli, Ps. auruginosa, etc., in pure culture, but in most cases, in association with other microorganisms. Staphylococcuses isolated in 25 strains were tested for enterotoxicity. From the strains examined, they produced: three strains of enterotoxin B and five strains enterotoxins B and C. The disease of the cows by staphylococcal infection of the udder influenced the fetal development of the fetus. From cows suffering from mastitis, calves were born weak and 1–2.5 kg live weight lower than from healthy cows. Calves (16 heads) who received colostrum from mothers with staphylococcal infection of the udder in association with other microorganisms, in fourteen cases were ill with signs of disorders of the gastrointestinal tract. Among calves born from cows suffering from mastitis, but who received colostrum from healthy cows, two of them fell from ten heads. In calves of both groups, the activity of cellular elements was determined by opsonophagocytic response. In the experimental group, where the calves received colostrum, were infected with staphylococci, the intensity of phagocytosis in all study periods was lower (from 0.4 to 1.9) compared with the control group calves. Quality of colostrum of cows also affected the activity of phagocytosis prplodu. In the experimental group, the activity of phagocytosis was throughout the experiment at one level – 33, and in calves that received colostrum from healthy cows, activity increased (after one day – 37, and for the second and third day – 40). Studies have shown that colostrum infected with enterotoxigenic staphylococci, especially in association, is dangerous for newborn calves. It causes them diarrhea and often leads to death. We have confirmed the etiological connection between cows disease with mastitis of staphylococcal etiology and enterocolitis of newborn calves.

The purpose of the study is to evaluate the effectiveness of the use of granular compound feeds with the introduction of probiotic preparation «Prostor», «Sporotermin» and sorbent «Fungistat-GPK» for fattening young rabbits. Studies of the effectiveness of full-size granulated feed were conducted on a population of young rabbits at the age of 45 days, selected according to the principle of groups of analogues and divided into 3 groups in the conditions of a private farm "O. V. Kuznetsova" 15 individuals were selected in each group. The live weight of the experimental groups exceeded the control group's peers when they reached age: 75 days by 85.0 and 251.0 g or 3.99 and 11.80%, 90 days - by 225, 0 and 435, 0 g or 9.04 and 17.49 % and 105 days-139.0 and 245.0 g or 4.37 and 7.70 %. The average daily increase in the control group was 26.55 g, in the experimental group 27.70 and 29.56 g, respectively. Hematological indicators of blood in the experimental groups indicate an increase in the number of red blood cells at the end of fattening (5,35-6,49 1012/l), and there is an increase in the total protein content in rabbits of the experimental groups to 75.82 and 75.99 g/l, which exceeds the values of this indicator of the control group by 3.45 and 0.17 g/l or 4.75 and 0.23%. This trend indicates an intensification of metabolic processes and the possible receipt of the largest increases in live weight. It was found that rabbits of the experimental groups had a slaughter yield of 63.01 and 65.03%, which exceeded the values of this indicator (56.84%) of the control group. The inclusion of enriched compound feeds in feed rations will help to improve the safety and productivity of reared rabbits and creates prerequisites for the large-scale use of these feed resources in the conditions of industrial rabbit breeding.

The authors highlight that broiler poultry is considered to be one of the most profitable and promising sectors of agriculture. At the same time, industrial technologies experience unsolved problems, such as death of young poultry in the first weeks of life due to the lack of resistible immune system, which is formed by the end of the third week. In this regard, development and application of immune stimulating specimens is a promising direction for stimulation and maintenance of natural poultry resistance and improve its economic parameters. The specimens used should not affect the quality and products safety. The example of such specimen is ImmuGuard; it was tested in the experimental vivarium conditions at the Department of Veterinary and Sanitary Expertise of Livestock Products And Hygiene of Agricultural Animals at the Institute of Veterinary Medicine And Biotechnology of Omsk State Agrarian University. The researchers arranged three experimental groups from Ross broilers on the basis of similarity. 1st experimental group received the specimen dosed 150; second group of broilers -250 g / t of water during 18 days from the date of hatching, and the 3rd group was arranged as a control one. Growth and weight parameters were determined by individual weighing of poultry every seven days. The quality of broilers’ meat was assessed by means of conventional methods used in veterinary and sanitary assessment of poultry meat. The experience showed a positive effect of the specimen on live weight gain of poultry: the authors observed body weight of broilers aged 42 days from first experimental group was 4.12 higher; broilers from the 2nd group 1.39% in comparison with the control group. The authors highlight a significant increase in the average daily growth: the 1st group showed the growth on 32.21% from the 22nd to the 35th day in respect to the control parameters. Organoleptic, physico-chemical and microbiological parameters of meat of all groups conformed to GOST 31470-2012 and SanPiN 2.3.2.1078-01 standards.

The study is dedicated to research into efficiency of influence of probiotic additive “Prostor” on productivity, chemical composition of meat of rabbits. The influence of synbiotic preparation “Prostor” on the population of male rabbits of hybrid form “Hypharm” of French breeding, selected at the age of 45 days. The study took place at the industrial complex of LLC “Lipetsk rabbit” in Khlevensky district of Lipetsk region. The animals were divided into control and experimental groups by the method of pairs-analogues. The control group of rabbits received the basic diet consisting of lall-mash feed PZK-92, while the rabbits of the experimental group received compound feed PZK-92-60-18, which included synbiotic “Prostor” in a dosage of 1 g/kg of feed. Meat quality assessment was carried out at the age of 105 days after control slaughter in the amount of 3 animals from each group. The use of the stated dosage of synbiotic preparation had a positive effect on the productive indicators of rabbits (live weight, average daily growth). The morphological composition data showed that rabbits of the experimental group outperformed rabbits of the control group by 23.84 % in terms of muscle mass. Analysis of the chemical composition of muscle tissue showed that the use of feed additives “ProStor” in a dosage of 1.0 g per kg of feed has a positive effect on meat productivity and quality of rabbit meat, which opens up prospects for the use of the preparation in the rabbit industry.

It is assumed that the combined effect of an effective probiotic and feed bentonites will enhance their positive effect on the growth, development, immunity of poultry, the quality of products, economic results of production. The purpose of the research was to study the effectiveness of the probiotic Vetkor and trace elements contained in bentonites in the compound feed of broiler chickens. Scientific and economic experiment has been carried out in the company “Uksyansky broiler” on broiler chickens cross “Smena-4”, which have been distributed in 3 groups on the principle of analogues. For each group 50 heads have been selected one day-old chickens. The conditions for rearing and housing the chickens were the same. The joint use of bentonite and probiotic in rearing and fattening broiler chickens have been studied. At the beginning of rearing the weight of chickens in all groups was almost the same and averaged 39,6 g. However, with increasing age of chickens not only their live weight increased, but also the difference between groups for this indicator. So, at the age of 7 days the chickens of the 1st experimental group had live weight higher than the control ones by 1,86 %, and the chickens of the 2nd experimental group by 2,00 %. The live weight of the broiler chickens of the control group at the end of rearing (age 42 days) was less than the live weight of the 1st broiler chickens of the experimental group by 101,14 g or 5,23 % (P < 0,05), and the 2nd experimental group by 132,14 g or 6,83 % (P < 0,01). The total and average daily increase in live weight of chickens of the 1st experimental group was greater by 5,34 % (P < 0,05), and the 2nd experimental group by 6,96 % (P < 0,05) than in the control group. Broiler chickens that consumed the probiotic Vetkor in the compound feed had higher growth energy than in the control. Against this background the best growth has been observed in broiler chickens of the 2nd experimental group who consumed compound feed with the addition of Vetkor and 3 % bentonite. It has been experimentally justified the use of probiotic and bentonite in the industrial production of meat of broiler chickens, it has been established a positive effect of probiotics and bentonite on the growth and development of broiler chickens, the quality of the resulting products.
