EXCHANGE PROCESSES IN THE BODY OF BROILER CHICKENS WHEN USING THE FEED ADDITIVE INNOVIT E 60
DescriptionVitamin E, having an antioxidant effect, also has a versatile effect on metabolism. It is proved that vitamin E is necessary for the integrity and optimal function of the reproductive, muscle, circulatory, nervous and immune systems. The feed additive Innovit E 60 was produced in the Russian Federation by the MEGAMIX company using innovative technology, which has no analogues in the world. The article presents the test results of the Innovit E 60 feed additive as a part of premixes for the purpose of enriching compound feeds for broiler chickens with vitamin E. The authors have found that the studied feed additive activated metabolic processes in the body of broiler chickens of ROSS 308 cross. Chickens of the experimental group better digested nutrients feed in comparison with analogues of the control group. A significant increase in the digestibility of crude protein by chickens of the experimental groups was found to be 1.11 and 0.92%, crude fat - by 2.11 and 1.85%, BEV - by 2.53 and 2.24%. The deposition of nitrogen in the body of the chickens of the experimental groups is higher than in the control group by 5.73 and 5.05%, and its use from the accepted - by 2.94 and 2.56%. By the end of the feeding, the difference in live weight was 90.3 (4.25%) and 68.5 g (3.22%), and feed costs per 1 kg of live weight gain decreased by 0.06 and 0.04 kg. The control slaughter of broiler chickens showed that the slaughter yield in the experimental groups increased: males by 0.6 and 0.4%, chickens by 0.8 and 0.5%; the mass of pectoral muscles of males - by 46.0 and 41.0g, chickens - by 43.0 and 36.0g. The feed additive Innovit E 60 in the diets of broiler chickens helps to improve the digestibility of the main nutrients of the feed, increase live weight, slaughter exit and exit of the pectoral muscles

EFFECTIVENESS OF USING MULTIKAN-6 WHEN GROWING YOUNG FOXES
DescriptionThe cost-effectiveness of animal husbandry in the conditions of Yakutia causes irreparable damage to viral diseases, such as salmonellosis, viral hepatitis, parvovirus enteritis and others. Based on this, in animal husbandry, increased attention is paid to the prevention of viral diseases. The work was carried out in the period from 2009 to 2012. in the conditions of LLC "Pokrovskoye animal husbandry" of the Khangalassky ulus of the Sakha Republic (Yakutia). Boning of young animals showed that all his indicators were higher for pups born in 2011. So body size and physique are rated higher by 15.15%, in males - by 20.58%. Hair color was better in females by 19.44%, in males by 22.66%. As a result, the classiness of the animals of the experimental groups was higher than that of pups born in 2010. The commodity properties of the animal products of experimental animals and its cost are consistent with the results of the valuation. The offset on the quality of the fur products of the experimental groups in 2011 was determined at 89.02%, which is higher than the 2010 results by 10.32%. The average cost of one fur of a silver-black fox in 2011 was 2225.62 rubles. Additional vaccination of the main herd of foxes in autumn against the viral diseases with the vaccine "Multikan-6" has a positive effect on the quality of the fur products. The economic effect amounted to 258.62 rubles per 1 skin of a silver-black fox (at 2020 prices)

FEATURES OF LINEAR GROWTH OF HOLSTEIN HEIFERS OF DIFFERENT LINES
DescriptionThe article presents the results of studying the growth and development of repair heifers of Holstein cattle belonging to the lines Vis Back Ideal and Reflection Sovering. The feeding and maintenance conditions in both groups were the same. In accordance with the generally accepted scheme of drinking during the milk period, the heifers received 180 kg of whole milk and 400 kg of its substitution. Starting from the age of 10-15 days, the heifers were grouped into groups of 15 heads each. The live weight and average daily increments of test heifers varied differently. Linear growth and average daily gains in the experimental group were higher than in the control group. Studies have found that heifers from the experimental group in all the studied periods were superior to heifers from the control group and for the entire period, the average daily increase was 16.5 g more. The average daily increments were at the level of 747.5 and 764.0 g, the live weight by the age of the first insemination was 373.5 kg in the control group and 381.8 kg in the experimental group. Linear indicators have significant differences in height at the withers at the age of 1 insemination; depth of chest behind shoulders in 6-month age and at 1-tion insemination; oblique body length (tape) in the age of the 1st insemination; the chest girth at 12 months of age and at 1-tion insemination. The results of the study show that the cultivation of repair heifers of the Vis Back Idial and Reflection Sovering lines of the Holstein breed further contributes to an increase in the growth of dairy productivity in farms and an increase in gross milk production

Description
The article discusses the relevance of the use of protected amino acids (lysine and methionine) in animal husbandry of the Krasnodar region, using the example of the farm "Krasnodar". The highest milk yield was obtained from cows with the combined addition of lysine and methionine in their diet. In relation to control (CR), the average daily milk yield in the group with combined additives (CR+L+M) was 38.4 kg/day. In addition, there was a positive effect of lysine and the combined additive (CR+L+M) on protein and fat in milk. Protected methionine (CRM) had no effect on the yield of fat and protein in milk. It was noted that additives of protected amino acids in groups with lysine and combined amino acids reduced the cost of dry matter (DM) and metabolizable energy (ME) per kg of milk. The results of our studies have shown that the productive milk response and its components are affected by the amount of the first limiting amino acid in the diet. Also, the supply of protected lysine changed the plasma concentration of animals and improved the availability of amino acids for milk protein synthesis

Description
An important factor in improving the efficiency of production in the agro-industrial sector is to improve the quality of poultry products and their processing. The article presents the dynamics of the influence of stimulating drugs on the productive qualities of the black African ostrich. The reserves of increasing the production of eggs of black African ostriches and its quality due to the use of stimulating drugs were revealed. The effect of the use of the drug called "Radostin Vitasil" on the chemical composition of eggs, egg production of black African ostriches is shown. The obtained research results convincingly prove that the mass of ostrich eggs of the experimental groups significantly exceeded the control by 5.45 and 3.11%, respectively. Changes in the mass of white and yolk of the egg of ostriches of experimental groups as a result of feeding the drug "Radostin Vitasil" affected the ratio of white/yolk, which slightly decreased towards the optimal. There was a significant difference in the content of carotenoids and vitamin A in the egg yolk of the I experimental group by 10.98% and 10.05%, in the II experimental group-9.15% and 6.35%, in comparison with similar indicators in the control group, respectively. There was an excess of vitamin E level in the eggs of the experimental groups in relation to the control by 6.73 and 3.42%. The results of incubation showed that the stimulating drug "Radostin Vitasil" had a positive effect on the process of embryonic development. The calculated economic efficiency of the drug "Radostin Vitasil" confirmed the feasibility of using this drug in the production of black African ostriches eggs

MORPHOLOGICAL AND CHEMICAL PARAMETERS OF OSTRICH EGGS
DescriptionThe article carries out an analysis of morpho-chemical parameters of ostrich eggs when l-carnitine is included in the diet. Studies were conducted on two groups of ostriches: I-received a standard diet, II-to the standard diet received L-carnitine at a rate of 300 mg per 1 kg of feed. From April to August we were studying the ostrich egg production, morphological composition of eggs, chemical composition of albumen and yolk, the amino acid composition of egg yolk, the level of cholesterol, fatty acids including saturated, unsaturated and polyunsaturated. It has been determined, that L-carnitine increases the egg production of ostriches by 24%. The weight of protein in the groups was 56.9-56.2%; yolk-27.6-26.7%; shell-16.4 -16.2%. The amount of cholesterol in the egg yolk of the 1st group ostriches was 12.2 mg, in the 2nd one it decreased by 7.4% (P>0.95) and amounted to 11.3 mg per gram of yolk. The level of amino acids in the egg yolk of the 1st and 2nd groups was approximately equal. The number of fatty acids in the 1st and 2nd groups was: saturated 39.5 and 39.7%, monounsaturated 49.99 and 49.80%, polyunsaturated 10.37 and 10.47% respectively. The sum of unsaturated and polyunsaturated fatty acids in ostrich eggs was 60.36 - 60.27%. The sum of ω3 and ω6 fatty acids is 10.18 and 10.25%. Ratio ω3: ω6-1: 3,3. The ratio of polyunsaturated to saturated acids was approximately 1:3, and polyunsaturated + monounsaturated to saturated-1.52 units (approximately 1.5 : 1).

EMBRYO PRODUCTIONS WITH CONVENTIONAL AND SEXED SEMEN USE IN "KUBAN” AGRO COMPANY
DescriptionAt the Kuban Agricultural Association OJSC, Ust-Labinsky District, Krasnodar region, a research has been carried out on obtaining embryos from cows and heifers of donors using sexed and conventional frozen seed. In the first experiment, 159 doses of ordinary frozen semen from 3 different bulls were used to inseminate 57 cows and heifers - donors. In the second experiment, 63 doses of normal frozen semen from 3 different bulls were expended for insemination of 21 cows and heifers of donors after treatment with super ovulation for 9 days. On the 7th day after insemination, the embryos were collected in experimental cows and heifers of the donors, their number was counted, and the quality was evaluated. As a result of the study, it observed that the obtained embryos from each donor were different in quantity and quality. The number of embryos, using traditional sperm, was from 1 to 42, and on average per cow 13.68 ± 2.45. Among them, 8.40 ± 1.08 embryos belonged to the first class, 0.35 ± 0.45 - to the 2nd class; 4.90 ± 0.94 to the 3rd class, as well as 4.90 ± 0.94 embryos were degenerated. After donor insemination with sexed sperm, 1 to 22 embryos were obtained, an average of 9.01 ± 4.03. Including 4.92 ± 3.04 embryos belonging to the 1st class, 1.31 ± 1.02 - of the second class, 0.28 ± 0.27 - of the 3rd class and 2.48. ± 0.71 degenerated. The results showed that the average number of embryos obtained using conventional sperm is larger compared to the use of sexed semen, regardless of the donor cow or heifer. Conclusion: the use of traditional frozen semen allows us to get more and better quality embryos from cows and heifer donors

THERAPY FOR ESCHERICHIOSIS OF NEWBORN CALVES
DescriptionBlood samples were taken from newborn calves and sent to the Rostov regional veterinary laboratory. The result of the general analysis of blood showed increased erythrocytes, increased red blood cell count and increasing white blood cell count as well as low hemoglobin levels. The results of the studies on the content of phosphorus, calcium, zinc, vitamins A and C in the blood showed that the sick calves have hyperphosphatemia, namely violations of the phosphorus-calcium ratio. A decrease in vitamin A in sick calves to 8.2±0.5 mcg% and zinc to 74.1±1.2 mcg% was found .This indicates a violation of mineral metabolism, which occurs due to a lack of minerals in the diet, but also with intensive withdrawal from the body, as a result of poor absorption and impaired renal filtration. As a result of typing on O-antigen, using a set of polyvalent and serogroup agglutinating O-coliseums, the presence of an adhesive A20 antigen was revealed. In the course of research, faeces from 9 newborn calves of 1-8 days of age were sent to determine the sensitivity to antibacterial drugs. Thus, 9 samples of cultures of E. coli sensitive to the following antibiotics: enrofloxacin, imipenem, meropenem, levofloxacin, and vancomycin, gentamicin, cefotaxime, and rofloxacin. Based on data from blood tests and sensitivity to anti-biotics, the animals were divided into 3 groups. And each group used three different treatment regimens. Observing the calves of the experimental groups, we found that the condition of the sick animals stabilized within 2-4 days. In the first group of 12 calves, 1 calf fell and 11 survived. In the second group of 11 calves, all survived. In the third control group of 12 calves, 7 fell, and 5 survived. When determining the sensitivity of Escherichia cultures isolated from calves of this farm to antibiotics, 100% sensitivity to levomycetin sodium succinate was obtained

HEMATOLOGICAL STATUS OF DOGS USING A BIOSTIMULATOR DEP
DescriptionIn veterinary practice, feed biologically active additives of plant and animal origin are widely used to improve digestion and absorption of nutrients, as well as to correct the normalization of metabolism. One of these biologically active drugs is denatured emulsified placenta (DEP) which has antiviral, anti-inflammatory, and immunomodulating properties. Therefore, the purpose of our research was to study the effect of DEP on the morphological composition of dog blood. During the research, it was found that the number of red blood cells in dogs of the control group was 1.57% or 0.12 x 1012/l more than in the experimental group. Erythrocytes of dogs in the control group had 0.37% more volume than the same indicator in the experimental group. However, each red blood cell of animals in the experimental groups was characterized by a high content of hemoglobin in it by 1.6%. Before the start of the experiment, the number of lymphocytes in the blood of dogs in the control and experimental groups was 4.07 and 2.34%, respectively, below the minimum reference value. The number of monocytes and granulocytes in the peripheral blood of dogs in the control group was 0.23 and 1.49% higher, respectively, than in the control group. The platelet content was higher in the control group than in the experimental group by 49.38 x 109/l or 27.3%. Changes that occur in the body of dogs under the action of a biostimulator indicate an increase in the production of antibodies to protect the body from infections and ensure the animal's immunity. They completely regulate the immune system
