Objective. Evaluate the efficiency and calculate the economic feasibility of using a new strain of lactic acid bacteria Lactobacillus sp. 13/2 in rabbit breeding technology under industrial conditions. Methods. Microbiological, economical, statistical. Results. The average weight of animals at the end of fattening was almost the same in both groups. However, when using a strain of lactic acid bacteria Lactobacillus sp. 13/2 in rabbit breeding technology, lower mortality rate in young animals and reduction of feed costs for their fattening was reported in comparison with the control. In the experimental group, animal mortality rate was 2.94 % versus 12.5 % in the control group, the average feed consumption for fattening per 1 kg of live weight gain decreased by 9 %. A positive economic effect in the experimental group was observed when the cost of sales increased per 1 head by UAH 7.48 (4 %) if the carcass price was UAH 140/kg. At the same time, the prime cost of 1 kg of gain decreased by UAH 1.98 (9 %). Also, the use of lactic acid bacteria reduced the cost of feed consumed per 1 head by UAH 1.77 (5 %) if the cost of feed was UAH 6/kg. Despite the decrease in the profitability of rabbit production by 1.5 %, the use of a new promising strain of lactic acid bacteria Lactobacillus sp. 13/2 during the fattening of rabbits had a positive effect on the maintenance of livestock, resulting in the decreased lost profit in the experimental group by UAH 277.08 (75 %). In terms of 1 head, the lost profit in the experimental and control groups was UAH 2.79 and UAH 13.99, respectively, due to which the use of lactic acid bacteria is completely regained. Conclusion. The positive effect of the use of Lactobacillus sp. 13/2 in rabbit breeding technology, which is manifested by a reduction in animal mortality and a reduction in feed costs for fattening, was established. The use of lactic acid bacteria helps to increase the economic efficiency of rabbit breeding, especially due to the reduction of lost profits. The economic effect is achieved without significant additional costs. The additional costs associated with the use of lactic acid bacteria are regained.

The Vitazar preparation has a rich natural composition and antioxidant properties due to the high content of fat-soluble vitamins – A, D, E, polyunsaturated fatty acids – linoleic, linolenic, oleic, palmitic, as well as trace elements Ca and K, etc. To study the preparation effects on young male minks, animals of the standard black breed of Scandinavian selection were chosen by origin, live weight and age using the method of analogous groups. A total of 128 males participated in the experiment – 32 heads in each group. The first group of minks was the control one. In three experimental groups, Vitazar was added to the general household ration with a different dose of 1.0.2.0.3.0 ml/head with a frequency of three times a week. The preparation was given during two summer months – July and August. During the experiment, the minks were weighed at the beginning of each month. After slaughter and primary processing, the skins were sorted in accordance with GOST 27769–88.According to the data obtained, Vitazar has a positive effect on the live weight and skin production of young minks. The drug in the diet of males at a dose of 3.0 ml/head contributes to an increase in live weight by 191 g, the skin size by 0.6 dm2, the proportion of defect-free skins by 8.0% and the quality indicators by 4.0%. The optimal dose of the preparation was found to be 3.0 ml/head.The use of Vitazar in the optimal dose in the diet of male minks increased the cost of one skin by 63.3 rubles. Thу “Vitazar” preparation was studied on young minks for the first time.

Mineral Feed Additives

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

Наведені результати випробування на 537 курчатах-бройлерах (635 контрольних) в умовах господарства препарату, виготовленого на основі розчину  полтавського бішофіту. У  курчат, яким давали препарат внутрішньо з водою,  порівняно з контролем, була більшою середня жива масса тіла у  43-добовому віці на 50 г, 73-добовому  – на 128 г і 111-добовому – на  103 г. До 43-добового віку загинуло із розрахунку від  початкової загальної кількості 16 (2,9 %) курчат-бройлерів  у дослідній групі і 30 (4,72 %) у контрольній. На контрольних  курчатах-бройлерах, порівняно із дослідними, мали економію на препараті, який не застосовували, і меншій кількості  використаних  кормів, але одержано значно більше збитків   через нижчі прирости живої маси тіла та більшу кількість загиблих. Економічна  вигода  від застосування препарату лише  до 43-добового віку курчат становить 5,8 гривень на  вкладену 1 гривню. Given results of test on 537 chickens-broilers (635 of control) in terms of economy drug produced on the basis of the solution of Poltava bishofit (SPB). Drug was given chickens-broilers of 5-day age group method internally with water in 3 cycles of 24-hour intervals over 7 times in each cycle and 7-day interval between cycles. The chicks, which were given the drug, compared with the control, had a greater average live weight of the body in 43-day age of 50 g, 73-day – 128 g and 111-day – 103 g it shows its positive effect on organisms of chicks up to 2,5 months (time of observations) after the last application in 38-th days of their lives. The drugs based on the SPB will have greater efficiency in the application of the repair chicks and adult hens, i.e. those who live more than 2,5 months. The 43-day age 16 broiler died of the calculation of the initial total number (2,9 %) in experimental group and 30 (4,72 %) in the control. On control broilers, compared with research, savings on the drug, which is not used, and smaller amounts of used feed, but we received much more losses due to lower increases in live body weight and more fatalities. The total value of the economic benefits of the drug only to 43-day age of chicks is 5,8 UAH on each invested 1 UAH.

The feeding effect of polyacrylamide (PA), mineral and vitamin additives (MVA) on the reproductive and productive qualities of sows, as well as the development and viability of piglets gained from them has been studied. The polyacrylamide, mineral and vitamin additives have been added to the sow diet of the 2nd and 3rd experemental groups. It has been done according to the animal need in minerals and vitamins. In proportion of 0,5/1 kg of live weight, the mineral and vitamin aditives, polyacrylamide have been added to the ration of sows from the 2nd experimental group. The mineral and vitamin aditives have been added to the ration of the 3rd group in such proportion: iron sulfate – 200, copper carbonate – 15, zinc – 84, cobalt – 3, manganese chloride – 69, potassium iodide (stabilized) – 170 mcg, vitamins A – 2.8 th. IO, D – 736 IO, B1 – 1.4 mg; B2 – 8.4 micrograms per head per day. The mineral and vitamin additives, polyacrylamide have been added to the sow diet of the 4th experimental group in the same proportion as it has been already mentioned above. The sows fed on PA and MVA for 60 days. The feeding was stopped 10 days before farrowing. The experiment on piglets has been carried out in 2 stages. The equalization period was 25 days (the ration of piglets from the control and experimental group was the same). The main period was 150 days (the control group of animals fed on standard compound fodder). The experimental group fed on additional PA and MVA. It has been noticed when the additives are added to the sow diet the gained piglets have an increase of viability, immun response (due to gamma globulins increase in blood proteins) and the average live weight by 23.3% during the rising period.

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 %.

Целью исследования являлось теоретическое обоснование и практическая реализация нового способа полива гидромелиоративной машиной Фрегат с гидроприводом на сложном рельефе с минимальными затратами на модернизацию и энергозатратами. Объектом исследования является экспериментальный кранзадатчик скорости, устанавливаемый на гидромелиоративную машину. Исследования проводились в сравнении с показателями машин серийного производства. В ходе исследования было установлено, что существующая технология полива не отвечает необходимым требованиям гидромелиорации и имеет низкую степень экономической эффективности. Предлагаемая технология полива решает вопрос неравномерного распределения влаги по площади, повышает урожайность и снижает стоимость обслуживания машины вследствие уменьшения числа поломок. Имеющиеся модернизации дождевальной машины (ДМ) Фрегат , позволяющие работать по предлагаемой технологии, сложны по конструкции, ненадежны и имеют относительно высокую стоимость модернизации и сезонного обслуживания. С целью увеличения экономии средств и упрощения процесса модернизации серийных машин был разработан и протестирован кранзадатчик скорости, позволяющий снизить риск эрозии почв, застревания колес тележек и, тем самым, простой машины с необходимостью ее ремонта. Главной особенностью экспериментального краназадатчика скорости является его горизонтальное расположение относительно тележки. Два плеча с увеличенной длиной позволяют задавать поливную норму путем касания вех в начале каждого сектора, где необходимо сменить скорость движения машины. Таким образом, происходит регулирование поливной нормы, выдаваемой машиной при ее движении по орошаемой площади. Получившийся экономический эффект позволяет утверждать о положительных результатах в проведенных исследованияхThe aim of the research is the theoretical justification and practical implementation of the new method of irrigation irrigation and drainage machines Frigat with hydraulic drive for complex tasks of modernization and energy consumption. The object of the study is an experimental speedadjusting crane installed on a water reclamation machine. The studies were conducted in comparison with indicators of machine production. In the course of research it was found that the existing technology does not meet the requirements of irrigation and drainage and has a low degree of economic efficiency. The issue of uneven distribution of the owner by area, high productivity and low cost of maintenance is being addressed. DM Frigat, which allows you to work on the proposed technologies, does not require the cost of modernization and seasonal maintenance. In order to increase cost savings and develop new models of machines, a speed control crane has been developed and tested to reduce the risk of machine destruction. The operation of the trolley is the horizontal arrangement of the trolley. The speed of the machine can be increased. Thus, regulation of the irrigation rate occurs. The resulting economic effect allows us to argue about the positive results in the studies

The results of studies on feeding biologically active additives suspensions of chlorella and Bactistatin in the diets of primates are presented. Its positive effect on the bioconversion of diets was experimentally established. The coefficients of digestibility of nutrients with dry chlorella and fishmeal in the composition of complete feed were determined. The obtained experimental data are important for the preparation of scientifically grounded and optimally balanced feeding rations, taking into account the digestibility of feed. This will optimally balance feed rations for all nutrients, while reducing feed costs and, as a result, increasing the profitability of keeping primates. It was found that the introduction of chlorella powder and fishmeal into the diet improves protein absorption by 6.83 and 5.66%, crude fat - by 2.61 and 3.92, crude fiber - by 4.78 and 4.25, NFES - by 4.15 and 2.26, crude ash - by 18.93 and 12.08%. The use of calcium and phosphorus macronutrients was higher in the 3rd experimental group, which received 14% chlorella in the main diet by 1.38 and 8.07%, respectively. In the 5th experimental group, which received 18.26% of the main ration of fishmeal, calcium was absorbed more efficiently by 4.77, and phosphorus - by 1.21%. The use of diet supplements in the form of a suspension of chlorella and Bactistatin helped to stimulate the bioconversion of nutrients in the diets used in the nursery for feeding monkeys, and enabled to maintain the main blood parameters within physiological norms.

Breeders of edible eggs, using various crosses of chickens, try to reduce the cost of production. In this regard, interests of hen crosses that produce egg products with low feed costs and low cost. One of these egg crosses of hens is “Lohmann brown light”. At the same time, domestic poultry farms successfully use the “Lohmann Braun classic”cross poultry. The aim of the study was to evaluate the egg productivity indicators of laying hens of the industrial herd of crosses “Lohmann brown classic”and” Lohmann brown light”. The study was carried out in the conditions of LLC Poultry Farm “Varaksino” of the Udmurt Republic. For the research, 2 groups of hens were formed, consisting of 6 batches each. As a result, hens of the studied crosses were characterized by approximately the same viability and level of livestock preservation – 94.1 – 94.3 %. Crosses of hens “Lohmann brown classic” and “Lohmann brown light” had minor differences in quantitative and qualitative indicators of egg production. Thus, egg production for the initial and average laying hens in the groups was at the level of 348.2 – 350.5 and 353 – 355.2 eggs, respectively. The amount of egg mass from the cross “Lohmann brown classic” hens was 22.9 kg, and from the cross “Lohmann brown light” - 22.6 kg. On an equal background of feeding, there were no differences in the cost of feed for the production of 10 eggs (1.29 – 1.31 kg) and 1 kg of egg mass (2.03 – 2.05 kg) in the studied hen crosses.

The article considers the problems of development of breeding pig breeding in Ukraine as a basis for the functioning of efficient and competitive commodity production. According to the results of the study, with the reform of agricultural production, commodity pig farming suffered significant losses, which had a negative impact on the efficient operation of breeding farms, especially breeders. The main reasons for the intensification of destructive phenomena in the field of breeding pig farming are the unstable level of purchase prices for pig products, low profitability and unprofitable production. It is obvious that the organization of the domestic selection system has a significant impact on reducing the cost and increasing the profitability of pig production, ensuring the quality and competitiveness of breeding (genetic) resources. The results of scientific research show that a significant increase in productivity in pig breeding is achieved through the effect of heterosis in interbreeding, and it is proved that under favorable conditions, the effect of crossbreeding is on average live weight gain of about 10-15% and feed payment 8- 10%. It is proved that to date there has been no clear pattern of a positive trend of change in the yield of piglets per sow in breeding pigs. Analysis of the procedure for receiving funds under the state program for partial reimbursement of the cost of breeding animals purchased for further reproduction shows that in 2017 compensation for breeding pigs and boars of domestic origin ("elite" class) was 20% of the planned due to lack of state budget funds for appropriate measures . In 2018, this amount of compensation was increased to UAH 5,000 per head. It was found that the unit cost of live weight of a breeding animal in 2017 was 2-2.5 times higher than in commercial pig farms. The high cost of production of breeding animals is due to higher feed costs due to components of the diet of mainly foreign production. It is obvious that the difficult financial situation determines the low investment attractiveness of the breeding pig industry for both domestic and foreign investors. Key words: breeding pig breeding, animal productivity, breeding breeders, market dynamics, import of breeding pigs, production cost, state support programs.
