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)

Description
The problem of providing people with food remains relevant in connection with the growth of the world's population. According to statistics, by the 21st century, the production of all types of food increased by more than 20%, while at the same time, the consumption of food products per capita increased by only 6%. In Russia, the production of food products, including dairy products and beef, is not growing at an insufficient pace. In this regard, in order to stabilize and develop the livestock industry in our country, it is important to improve the material and technical base for transferring it to the intensive path of development - maximum production with the lowest labor and material costs. Based on the achievements of scientific and technological progress and a systematic approach to the production of high-quality products, an intensive direction in the livestock industry should be based, the use of highly efficient milk production technologies, based on the achievements of science and technology, and the management of cost-effective dairy cattle breeding. Of particular strategic importance is the effective improvement of the breeding qualities of cattle and the creation of conditions for the formation and effectiveness of the manifestation of genetic capabilities in animals. Currently, the problem in the livestock sector in Russia is the insufficient provision of the feed base and the introduction of rations in the technology that are adequate to the needs of highly productive animals. Statistics show that in the Russian Federation the manifestation of the genetic potential of livestock is only 60-70%. To solve this problem, fodder production should be improved; the existing set of measures should be effectively used in the development of progressive methods of forage preparation and feeding rationing, taking into account the physiology of animals. Livestock farmers of PJSC "Rodina" of the Kanevsky district of the Krasnodar region, having the status of a breeding plant for cattle breeding of the Holstein breed, reached rather high indicators for improving the genotype of dairy cattle and the effectiveness of its manifestation

Description
The article provides a convincing argument for the preference of wool and fur products over artificial and synthetic textile fibers. It is noted that artificial fibers and synthetics have negative ionization, while natural wool has positive ionization. It is emphasized that negative ionization is far from harmless to humans. The analysis of the state of sheep breeding in the Russian Federation is given and this industry in the Rostov region is characterized against this background. The data on the number and productivity of sheep of the main age and sex groups, the production of young animals per one hundred ewes are presented. The characteristic of tribal resources of the country and region is given. The breeding base of the industry in the Russian Federation is represented by 205 breeding organizations, including 3 breeding and genetic centers, 44 breeding plants, 145 breeding reproducers and 13 gene pool farms, which contain 1389.8 thousand sheep (39.0 % of their total number in agricultural organizations and 6.6 % of the sheep population in farms of all categories), including 904.7 thousand Queens (35.0 and 6.2%, respectively). The breeding base of the Rostov region has eleven farms, of which 6 breeding plants for such breeds as the Soviet Merino and salskaya and 5 breeding reproducers. In addition to these breed resources, there are breeding reproducers for the qigai and edilbaev breeds in the region. Total number of breeding sheep in the region is almost 44 thousand. The article indicates main problems in the development of the industry and ways and means to solve them

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

MAINTENANCE AND USE OF BREEDING COWS OF THE HOLSTEIN BREED IN THE CONDITIONS OF INTENSIVE TECHNOLOGY
DescriptionConsidering the fact that in Russia the development of dairy cattle breeding is based on increasing milk production in terms of providing this product, the further increase in milk yield and quality of cow's milk remains important. Some farms in Russia, including the Krasnodar region, have reached high milk production rates in whole herds of up to 12-13 thousand kg of milk per cow. Today it is important to “propagate” such farms. To achieve this goal, it is necessary to study their livestock breeders experience, approaches to the selection of cattle (calves, heifers, cows), to form herds of animals that can get high milk yield under the conditions created for them. The farm in which we conducted our scientific research is distinguished by the fact that much attention is paid to maintaining a high level of breeding and breeding, as well as to creating optimal factors for keeping, feeding and caring for animals. Agroholding Step includes 5 farms in divisions: one in the Kuban Step, two in public company of shareholders “Rodina” and two in shareholder company “Novoplastunovskaya” Three farms are located in the village of Chelbasskaya, where the cowsheds were reconstructed and equipped with new equipment. In the village of Novoplastunovskaya, new buildings were built in the territory of the old farm, and the 4th farm was built in 2018 in the new territory. All farms contain highly productive breeding cows of the Holstein breed. The Russian information programs “Selex-Dairy Cattle” and Israeli program “AfiFarm” were introduced. We have studied zoohygienic conditions in various buildings of dairy farms in the spring, where animals are constantly kept. The results obtained indicate that the cows are kept in comfortable conditions, allowing them to eat a balanced diet in accordance with their needs and to avoid many stresses what is important for the secretion of milk. Indicators of genetic potential for milk production of cows and the effectiveness of its manifestation are also determined

BEEKEEPING AS A NECESSARY FACTOR OF APC DEVELOPMENT
DescriptionThe creation of stable agrocenoses requires ensuring a high pollination rate by maintaining a certain number of bee colonies per unit area. In Russia, over the past four years, the number of bee families has decreased to 3.1 million. For the full pollination of the entomophilous crops available in the Russian Federation, more than 7 million bee families are needed. The shortage of bees in Russia led to a massive import of bee packages from Uzbekistan, which significantly reduced the employment and profitability of residents in Russian agriculture. To ensure socio-economic well-being in rural areas, it is necessary to establish the formation of their own bee packages in the early spring. To do this, it is advisable to use instrumental insemination of bees, which allows to increase the productivity of the bee colonies by 25-40% and receive early bee packages with fetal uterus. It is necessary to carry out technical re-equipment of the industry, having established the production of mobile bee pavilions, beehive loaders, and honey pumping complexes. The development of beekeeping due to the manifestation of the multiplier effect will contribute to increasing the efficiency of the entire agricultural sector of the country

PROBIOTIC FEED ADDITIVES USED IN PIG FARMING
DescriptionThe article provides a review of domestic patent information on the effectiveness of using modern probiotic feed additives in pig farming practice. The inclusion of probiotic feed additives in the diets of pigs is aimed at excluding pathogenic and opportunistic microflora from the intestinal microbiocenosis, increasing the productive action of feed and intensifying metabolic and immune processes in the organism. The introduction of probiotic feed additives into the diet of pregnant sow and suckling pigs, as well as weaned piglets, allows achieving high indicators for the safety and productivity of young animals, which is very important for the cost-effective development of production. The ability of probiotic feed additives to normalize the microflora of the gastrointestinal tract of newborn piglets provides increased resistance to mass gastrointestinal diseases, as well as increasing the safety and viability of piglets. Thus, probiotic feed additives are an important component of the modern diet of farm animals at all stages of their development. At the same time, the most popular and effective for modern pig farming are multicomponent probiotic feed additives that contain a complex of probiotic cultures with different biological effects on the organism, sorbents that often act as prebiotics, enzyme preparations and other biologically active substances that provide a positive multifunctional effect on the organism of farm animals

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
