The results of studies on the effect of various doses of cobalt with an optimized level of sulfur in rations of Askanian meat-and-wool ewes on digestibility of nutrients of consumed feed and digestibility of the studied mineral elements are presented. It was established that the level of nutrient digestibility of rations was higher in ewes of the experimental groups, which, to the generally accepted norm, were additionally injected with cobalt chloride in the amount of 10 %, which was equal 0.825 mg, 20 % – 0.900 mg, and 30 % – 0.975 mg per head per day . As a result of the conducted research, it was found that the ewes of the second experimental group differed in the highest indices of digestibility of nutrients of the ration, which increased the rate of cobalt by 10 %. The additional introduction of 20 % and 30 % cobalt to the basic ration did not contribute to a further increase in the digestibility factors of nutrients in the body of ewes of the experimental groups. The research has shown that the uptake of cobalt by experimental ewes increased as this element increased in the rations. Thus, 0.31 mg of cobalt was assimilated by the ewes of the second experimental group, which is 0.06 mg or 20.0 % higher compared to the control group; to the third-group of ewes by 0.07 mg or 28.0 % and to the fourth-group ewes by 0,08 mg or 32.0 % compared with analogues of the control group. However, when calculating these indicators in relative terms, it was established that the highest percentage of cobalt absorbed from that received was in the ewes of the second experimental group. Their advantage relative to the control group was 4.60 % (P <0.01), and III and IV experimental groups – 2.11 and 0.19 absolute percent.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

The mineral elements interact not only among themselves, but also with the organic components during complex metabolism process. Identifying the features of the feed nutrient substances relationship allows you to direct the body’s metabolism in the direction of their effectiveness and to obtain the maximum output from the animals. The experimental part of the work was carried out on poultry complex “Agrofirma Zalesnyy” of the Republic of Tatarstan from January to May 2016. The objects of research were female turkey-broilers of “Hybrid Converter” cross, mineral supplement “Tseostimul”, probiotic “Provagen” and symbiotic preparation of a new generation. With this aim, four groups of turkey were formed of 40 heads. The first group was a control one and received a basic diet, adopted by the poultry farm. The second group received the basic diet, added with mineral supplements with a dosage of 30 gramm per 1 kilogramm of feed. Turkeys of III-experimental group was added to the diet of probiotic preparation “Provagen” at a dose of 3 gramm per 1 kilogramm of feed. The turkeys of IV-test group received in addition to the basic diet a symbiotic drug rate of 20 gramm per 1 kilogramm of feed. The main diet was consisted of complete feed. Duration of the experiment was 112 days. By the end of the experiment the body weight of experimental groups exceeded the similar index: in the control group to 1082 gramm (р ≥0,001), in the first test group to 781 gramm (р ≥0,001), in the second test group to 1339 gramm (р ≥0,001), in the third group with addition of symbiotic drugs or to 12.3%, 8.9% and 15.3% respectively. The numbers of leukocytes was decreased from 34.2 109/L to 33.3 109/L in I experimental group, to 33.2 109/L in II and to 34.4 109/L in IV experimental group. The mass of internal organs was significantly higher in females of experimental groups. Thus, the weight of the liver of experimental groups was greater to 12.3%, 8.9% and 15.3%, compared with the control group.

The purpose of the research is to increase the effectiveness of the supplement Reasil on the growth of milk-fed calves. For the scientific and economic experience, three groups of calves were formed (control, 1 and 2 experi-enced). Groups of animals of 10 heads were formed according to the principle of analogues. The indicators of live weight, growth and blood of calves were studied after Reasil use in a diet: Reasil HumicVet as a liquid form, and Reasil Humic Health – reduced to powder. In the experiment, animals of a black-and-white breed were used. The Reasil feeding in the diet contributed to an increase in the live weight of milk-fed calves in the 1-st and the 2-nd experimental groups at two months of age by 5.65 and 5.48 kg (or by 7.4 and 7.2%), respectively, compared to the indicator of the control group analogues. The average daily growth of calves of the experimental groups exceeded this indicator of control animals by 96 and 82 g, respectively. The blood of calves of the 1st and 2nd experimental groups, showed that hematoglobin was higher by 15.7 and 11.4%, red blood cells – by 16.5 and 15.1%, and the alkaline reserve – by 5.2%, compared with blood of calves from the control group, which indicates the activation of metabolic processes in the body. The total protein amount in the blood serum of animals from the experimental groups increased by 8.4 and 5.9% respectively, compared to the tests of calves from the control group. The albu-min content of animals of the 1st experimental group tested was higher by 5.3%; from the 2nd experimental group there was no significant difference compared to the control. The number of gamma-globulins in the blood of ani-mals of the experimental groups increased, which indicates an increase in defense reaction of animals. The con-tent of calcium in the blood serum of calves from the experimental groups was higher by 8.3 and 5.9%, phosphorus – by 4.8 and 2.4%, which indicates a more effective use of these mineral elements.

The effect of pyridoxine hydrochloride on the body mass of animals, absolute and average daily increment, relative growth rate, growth factor of live weight and multiplicity of increase in live weight of calves in the early stages of postnatal ontogenesis were studied. For the experiment, six groups of one-day calves (control and five experimental) were formed, with 5 animals in each, which, in addition to the main diet (MD), fed pyridoxine hydrochloride in different doses, according to the scheme: control group – MD, I experimental group – MD + 1 mg/kg g. m pyridoxine hydrochloride, II – MD + 2 mg/kg g. m of the preparation, ІІІ – MD + 3 mg/kg of w. m., IV – MD + 4 mg/kg g. m and V experimental group – MD + 5 mg/kg g. m pyridoxine hydrochloride. Conditionally, the research was divided into four periods: colostrum – from birth and up to 5 days, until the formation of digestion – from 5 to 21 days, the period of the formation of digestion scar – from 21 to 60 days and the end of the milk period – from 60 to 90 days. It was established that feeding to calves with pyridoxine hydrochloride resulted in an increase in the live weight of 60 days of calves by 5.9% in the second group (P < 0.05), by 8.7% in the third group, by 8.3% in IV and 9.2% in V groups (P < 0.001) and for 90 days it was higher by 9.3%, 9.1%, 9.2% and 9.1% respectively (P < 0.05). The highest average daily increments were in the colostrum period in calves IV and V groups, which were added to the main diet, respectively, 4 and 5 mg/kg b.w. pyridoxine hydrochloride, in the period prior to the formation of digestion scar in calves of group IV, in the period of the formation of digestion scar in calves of the III group and at the end of the milking period in calves of group V. Absolute incresements of calves in the colostrum period and the period prior to the formation of digestion scar were the highest in calves of Group IV and the difference in control was respectively 0.34 and 1.05 kg. During the period of the digestion scar formation and the end of the milk period, the highest absolute increases were in calves of group V, which was added to the main ration of 5 mg/kg b.w. pyridoxine hydrochloride. The highest increase in body weight of calves in colostric period and prior to the operation scar rate was in group IV, the period of digestion scar formation was in the third group and during the completion period of milk in the second group of calves. In colostric period the increase of live weight was higher in calves III, IV and V groups of 5 to 21 days in calves of group IV, from 21 to 60 days in the third group and during the completion period of milk in the second group of calves.

Dogs play a significant role in human life. It is difficult to list all the various aspects of their application. But along with the positive qualities of using dogs is the problem of regulating the numbers of stray animals. Among the agents that stimulate the processes of repair and regeneration, increase the basic physiological mechanisms of protection of the body are humic preparations such as sodium humate. Taking into account that preparations of natural origin have a special influence on the inflammatory process, it is necessary to find and study the possibilities of using biological preparations of humic acids. Six animals were selected for the detection of the effect of sodium humate on dogs by analogues. Castration was carried out in an open manner according to conventional methods After surgery, the animals were subcutaneously injected with a 0.1% solution of sodium humate at a dose of 0.1 ml per 1 kg of body weight, and the control saline solution once a day for 14 days. Examination of wounds and thermometry was performed twice daily for 16 days. Castration wounds were treated with antibacterial aerosol once daily. No additional medication was used. In the post-castration period, all operated dogs did not observe any bleeding, loss of the common vaginal sheath, intestine, cult of the seminal cord, or other complications. Since the third day in the general condition of the animals of the experimental group significant changes were observed, which were expressed in the attenuation of the signs of inflammation, which was manifested in the reduction of hyperemia of the wound edges and their edema. The tenderness of the scrotal tissue was noted, and the scrotal skin became folded. In control animals the development of the inflammatory process was more pronounced and occurred 2 to 3 days later than in the experimental animals. On the third day after surgery, the control animals showed clinical signs characteristic of acute inflammation: hyperemia, sharp pain and swelling of the scrotal tissues, elevated local temperature. In two animals of the control group swelling was spread beyond the scrotum - a slight swelling of the prepuce was noted. These signs were manifested against the background of general depression and decreased appetite. Recovery occurred on day 12 in the experimental group and on day 16 in the control one.

The objective of these investigations was to examine possibilities for preventing fatty liver in cows during the peripartal period using the preparation HEPARENOL which includes methionine, lysine and choline in its composition. Investigations were performed on cattle of the Holstein breed whose average production during their last lactation was 8120 liters. The cows included in the experiment were divided into three groups of 10 cows each. Cows of the first group were administered the preparation HEPARENOL perorally 5-7 days before partus in daily doses of 50 ml per animal, and then daily during the first seven days after parturition in daily doses of 100 ml per animal. The second group of cows were administered the preparation in the same way as the first group, but they also received vitamin C injected deep i.m. in doses of 1000 mg per animal per day. The third group of cows were not exposed to any treatment and served as the control group. The body condition of the cows was marked according to the system Elanco Animal Health Bulletin Al 8478. Blood samples were taken by puncture of the jugular vein before the beginning of treatment, and on the third and 12th days after partus. The glucose concentration was determined in the blood samples. On the 12th day after partus, liver tissue samples were taken by biopsy for pathohistological examinations. Since the cows were fed in the same way and were in the same phase of the production-reproduction cycle, the average score of the body condition before treatment was approximately the same. However, on the 3rd day after partus, cows of the second experimental group showed average values that were significantly lower in comparison with the other two groups of cows. It is very interesting that a significantly lower value of glycemia (x=1.93?0.34 mmol/l) was established in the same group of cows at this time. In cows of the first experimental and the control group, glycemia was approximately the same during the examined period. In cows of the second experimental group on the 12th day after partus the glucose concentration significantly increased (x=2.42?0.58 mmol/l) against the values obtained for the 3rd day, but it was still significantly lower in comparison with the glycemia of cows of the first experimental (x=3.34?0.61 mmol/l) and the control group (x=3.48?0.49 mmol/l). Practically, throughout the entire period glycemia was statistically significantly lower in the second experimental group in comparison with the other two groups of cows. The degree of fatty liver on the 12th day postpartally, or five days after the end of treatment, was the lowest in cows of the second experimental group. In order to stress the differences, it is pointed out that there were two cows without fatty liver in the second group, while there were no such cows in the first experimental or in the control group. This group contained the smallest number of cows with a mean degree of fatty liver (n=2), while two cows had very strong fatty liver. There were no differences between the control and the first experimental group in the number of cows with a mean degree of fatty liver, with the exception that the control group had two and the first experimental group one cow with a mild degree of fatty liver. It seems that treatment using the preparation HEPARENOL, or methionine, lysine and choline, before and after parturition did not have a significant effect on the incidence and degree of fatty liver. Only cows with additional and simultaneous treatment with vitamin C had a lower incidence and degree of morphological changes in the liver, in addition to the sigfnificant changes in body condition and the blood glucose concentration.

Aim: This paper presents the results of the studies on "Stimix Zoostim" and "Normosil" probiotics and their influence on fecal microflora, hematologic indicators, immunoresistance, nutrient digestibility, and growth intensity of mother-bonded calves. Materials and Methods: The calves of the control group were fed with their basic diet (BD) without "Stimix Zoostim" or "Normosil", whereas the calves of the experimental group were fed with their BD supplemented with "Stimix Zoostim" and "Normosil". For 10-20-day-old calves, the daily dose was 10 mL per head, whereas 21-90-day-old calves received 15 mL of probiotics per head per day. The calves of the experimental group were administered probiotics every day. Calves aged 10 to 60 days received probiotics with milk, and then at the age of 61 to 90 days, received probiotics with water. (This is a sequential process. At 60 days old, calf rearing with milk stops, and after that, we use probiotics added to water to rear them). Both groups were administered probiotics twice a day, specifically 50% of the daily dose at each feeding time. Results: The results in this study proved that "Stimix Zoostim" and "Normosil" probiotics exhibit high probiotic activity and have a positive effect on the calves' fecal microflora. Feeding the calves with probiotics resulted in a significant increase in the number of normal flora, such as lactic acid bacteria and bifidobacteria, and a decrease in the amount of Escherichia. It also resulted in an increase in red blood cells, hemoglobin, and ?-globulins within the physiological range. In our study, we found that the phagocytic reaction in the blood serum of the experimental group was slightly enhanced, suggesting a high response of the body to infectious agents. Conclusion: Thus, the group of calves receiving probiotic "Stimix Zoostim" exhibited an exceedance of phagocytic activity by 4.8% and the group receiving "Normosil" by 4.4%, in comparison with the control group. The daily dose of 10 mL of probiotics per head for 10-20-day-old calves and 15 mL per head for 21-90-day-old calves also had a positive effect on nutrient digestibility, growth, and forage consumption. The economic benefit per animal was 149.23 and 157.0 rubles, respectively.

To study the effect of different doses of feed additive TC VMP in the composition of complete feed granular feed on the digestibility of nutrients and retention of Nitrogen in young rabbits with intensive cultivation technology, a scientific and economic experiment was conducted. To carry out a balance experiment, four rabbits were selected from each group of test animals, which were placed individually in specially equipped cages. The experiment was performed by the method of groups in three periods: preparatory – 7 days, preliminary – 5 days, accounting – 6 days. Analysis of feed, feces, urine was performed according to generally accepted methods of zoochemical analysis. For feeding young animals of experimental groups of rabbits used complete ration granular feed, in the structure of which there was a different content of feed additives. Rabbits were fed complete feed granular feed where the content of wheat bran was – 25.7%, barley grain – 13.0%, corn grain – 5.0%, soybean meal – 2.5%, sunflower meal – 15.0%, hay flour alfalfa – 25.0%, oats – 10.0%, table salt – 0.35%. The nutritional value of granular complete feed for all experimental groups of rabbits was the same. According to the balance experiment, the best indicators of nutrient digestibility were found in young rabbits of New Zealand breed, with a feeding dose of feed additive TC VMP in the composition of granular feed – 3.5%. At this dose, the coefficient of digestibility of organic matter was 63.3%, crude protein – 67.9, crude fat – 74.1, crude fiber – 24.8 and nitrogen-free extractives – 72.3%, which increased the digestibility of organic matter by 2.5%, crude protein by 3.9% (p≤0.05), crude fat by 2.9%, crude fiber and BER by 1.9 and 2.6%, respectively, in young rabbits, with intensive rearing on meat. It was found that in the body of animals of the experimental group, which were fed as part of the feed additive of TC VMP in the amount of 3.5%, the ratio between the amount of nitrogen absorbed from the consumed rabbits of this experimental group was dominated by animals from the control group by 2.92% 0.05). Thus, research data indicate a positive effect of feed additive TC VMP on the growth and development of young rabbits of New Zealand breed. Key words: digestibility coefficient, young rabbits, compound feed, organic matter, protein, fat, fiber, copper.

The article presents the research results of the compound feed with different methionine sources and its effect on live weight, slaughter rates, nutrient digestibility, nitrogen balance, chemical and amino acid composition of the longest back muscle, blood morphological rates of young rabbits. The results of the study indicate that the rabbit live weight of the 2nd experimental group, which has got to the compound feed with synthetic LM at the age of 70, 77 and 84 days significantly exceeds the control group by 2.1, 2.5, 2.6% and (P<0.01) respectively. Feeding on the compound feed with the addition of L methionine contributes an increase in the indwelling mass by 2.7 (P<0.05). The kidney carcass mass increases by 5.6% (p <0.05), the liver mass – by 10.6% and the longest back muscle mass – by 0.1%. The slaughter yield is higher in the second group than in the control group. In the third experimental group is higher by 2.7 2.8% respectively. . The young rabbits consuming the ration with LM have higher digestibility indices than control group. The second group exceeds the control by 0.3, 0.3, 0.4, 0.7 and 0.1%, respectively with the digestibility of organic matter, protein, fat, fiber. The nitrogen balance data analysis shows that nitrogen has been fed by 0.4 g or 0.8% more in the second group than in the control group. The emptied feces have less nitrogen by 0.01 g or 0.8% in the second group and by 0.01 g or 0.8% less than in the control group. The compound feed with the addition of LM affectes the chemical composition of the longest rabbit back muscle. There is more protein by 0.03%. in the muscles of the second experimental group than in the control sample. The young rabbits of the second experimental group have a higher content of amino acids in the muscles and they outperforme the control analogues of the third experimental group by 1.9 and 4.2% respectively. The rabbits feeding on LM fodder have higher morphological blood rate. Analyzing the above, we can conclude that the feed with methionine content of 0.41% and its source in the form of L methionine, probably improves the performance of young rabbit meat productivity. Key words: rabbits, methionine, live weight, compound feed, slaughter output, digestibility, nitrogen balance, amino acid, morphology.

The article reflects the results of a study of the morphological composition of blood, indicators of metabolism and the content of hormones in the blood plasma of gonadectomized cockerels of the Adler silvery breed. In the experiment, 40 males were used at the age of 6 weeks, of which two groups were formed, a control and an experimental, 20 heads each. It was found that during the preparatory (leveling) period, the clinical state, morphological composition of blood and metabolic parameters in the experimental group of males did not differ from each other and were within the limits of their physiological values. There were also no differences in blood glucose concentration, protein content, triglycerol, cholesterol, uric acid, as well as the activity of alkaline phosphatase, alanine and aspartate aminotransferase in the blood plasma of cockerels in the experimental and control groups during the preparatory period. Gonadectomy of males by surgical intervention at the age of six weeks did not significantly affect the morphology of their blood on the third day, with the exception of ESR, the value of which in birds of the experimental group was 1.9 times higher than in the control. In gonadectomized males, the number of platelets in the blood decreased by 30.7% compared to the control, which indicates a decrease in platelet activity and is probably associated with their participation in blood coagulation processes in the body after gonadectomy. Other indicators of the morphological composition of blood, namely, the number of erythrocytes, leukocytes, lymphocytes, eosinophils and neutrophils in gonadectomized males did not change compared with the control. It was found that the concentration of glucose in the blood, as well as total protein and uric acid in the blood plasma of males who underwent gonadectomy on the third day of the research period were at the level of the values of the control group birds and corresponded to the physiological values of these parameters in clinically healthy birds. On the 125th day of the main period in gonadectomized males, the level of glucose and protein, as well as indicators of lipid metabolism, namely, the concentration of triglycerol and cholesterol in the blood plasma did not change, while the content of uric acid increased by 23.7% compared with the control. It was found that the content of cortisol in the blood plasma of gonadectomized males was 3.2 times lower, and testosterone 10.2 times lower than in the control. So, gonadectomy of cockerels does not affect the morphological composition of the blood, indicators of the metabolic status of the bird, but it helps to reduce the content of cortisol and testosterone in the blood plasma. Key words: roosters, gonadectomy, blood morphology, metabolic parameters, enzyme activity, cortisol, testosterone.
