Abstract The research aims to determine the influence of the new technology of feeding dromedary female camels on their dairy productivity. Milk camels of the I control group were kept in conditions of pasture with supplementary feeding of 3 kg of wheat bran, milk camels of the II experimental group, in addition to the main diet - pasture forage, received additional feeding with 3 kg of concentrated feed, consisting (wt.%): a mixture of grain waste - 50, cotton husk - 10, wheat - 25 and barley - 15 with a total nutritional value of 1.0 feed units, 9.46 megajoule of metabolizable energy and 90.5 g of digestible protein. Studies have shown that the dairy productivity of experimental groups of milk female camels gradually increases from the beginning of the lactation period. For 12 months of the lactation period, the dairy productivity of dairy camels in the control group was 2995.3 liters, in the II experimental group - 3236.2 liters in the III experimental group - 3467.9 liters. The average fat content of camel milk from sucking dromedary female camels, depending on the level of feeding, averages 4.22-4.39%.

The aim of the research is to determine the amount and nutritional value of pasture forage eaten by dromedary camels on saltwort pastures. As the results of the experiments showed, adult female camels consumed, on average, over three years, 19.2 kg of sagebrush-saltwort-herb pasture pasture food of the above-described saltwort pasture with an initial moisture content of 35.7% and a nutritional value of 0.44 feed units, 4.96 MJ of exchange energy , 50 g digestible protein, 2.92 g calcium, 0.73 g phosphorus and 27 mg carotene in 1 kg of pasture feed at natural moisture. Adult single female camels with live weight in the range of 530-550 kg in the indicated amount of pasture forage (19.2 kg) consumed an average of 12.29 kg of dry matter, which contained 8.45 forage units, 95.23 MJ of metabolizable energy, 960 g of digestible protein, 56.06 g of calcium, 14.01 g of phosphorus and 518.4 mg of carotene. The actual provision in digestible protein was 115.8%, as they consume 960 g at a rate of 829 g, which indicates good grazing and forage conditions of saltwort pastures. The indicated feeding level of single female camels provided the animals with the average daily gain of 670 g. On a similar type of saltwort pastures, a 1.5 year old young camel stock with an average live weight of 265 kg consumed about 11.5 kg of pasture forage, which contained 7.36 kg of dry matter, 5.06 forage units, 57.04 MJ of metabolizable energy , 575 g of digestible protein, 33.6 g of calcium, 8.4 g of phosphorus, and 310 mg of carotene. At the same time, the average daily gain of the experimental young stock for the grazing period is 620 g.

We studied the milk production, the condition of nutritional status, the intensity of growth and development of suckling lambs and the activity of individual enzymes in the blood plasma  with optimization of the level of protein and energy in rations of lactating ewes of Ascanian meat and wool breed in the Foothills of the Carpathians. It is known, that the geochemical zone of the Carpathian region is characterized by specific protein composition and energy value of feeds. Therefore, studies aimed at adjusting the rations of pregnant and lactating ewes of the Askanian breed in this zone according to the level of protein and energy in the winter-stall period and their influence on the productive qualities and course of metabolism in animals, have an important scientific and practical significance. The study was carried out on 2 groups of lactating ewes-analogues (10 heads each) of Askanian meat and wool breed with crossbred wool in the  «Hrusyatychi» Farm of the Institute of Agriculture of the Carpathian region of the National Academy of Sciences, during the stall period. The duration of the experiment is 90 days. The diet of the ewes of the control group consisted of 1.6 kg of hay meadow, 0.5 kg of whole grain of oats and 0.5 kg of compound feed according to the prescription K80-6-89, the research group's ewes received experimental mixed feeds, in which the part of the grain base was replaced with pea bran, sunflower and canola rapeseed meal and linseed meal. The diet of the control and experimental groups differed insignificantly. The diet of the control group of ewes contained 21.7 MJ of exchange energy, 187 g of digestible protein, 2.29 kg of dry matter, and in the diet of the experimental group, respectively, 22.1 MJ of exchange energy, 188 g of digestible protein and 2.26 kg of dry matter . In one kilogram of dry matter, the fodder of the sheep of the control group contained 9.5 MJ of exchange energy, and the experimental group animals – 9.8 MJ. It was found, that adjusting the level of protein and energy in the standard feed for lactating ewes in the zone of the Carpathians by introducing into it of local high-protein supplements   provides maintaining the weights for the lactation period;  increase  the average daily milk yield after suckling lambs by 23.8%;  increase the average daily growth of suckling lambs by 6.7–13.9%; physiological level of activity of alanineaminotransferase, aspartateaminotransferase and lactatedehydrogenase in blood plasma.

Correction of feeding in the dry period is relevant, especially in the conditions of distant mountain keeping used to keep breeds in which metabolic processes are more intensive, and, accordingly, a greater amount of nutrients should be supplied with the feed. To establish the optimal amount of nutrients in the diets required for pregnant ewes, in the conditions of the distant mountain keeping of the North Caucasus in 2018, after the end of the breeding campaign, 120 ewes of the Tushino breed were selected, going to the third lambing. They were divided into 4 groups of 30 heads per each. The ewes of the first control group received a food ration prepared in accordance with the standards of the Federal Science Centre for Animal Husbandry (2003). The diet of ewes of the second, third and fourth groups was increased in total nutritional value by 10, respectively; 15 and 20%, compared with the diet of the control group. For the entire lactation period, the average daily milk yield of the ewes of the III experimental group, who received a diet where the total nutritional value of feed was 15% higher than that of the control group, was 719.2 g, which is higher than the indicators of the ewes receiving a diet prepared according to the standards of the FSCAH. by 32.1% (P ≤ 0.001); and ewes receiving 10% more nutrients than animals of the control group by 16.1% (P ≤ 0.01) and IV experimental group receiving 20% more nutrients substances, by 5.1%. Thus, we can conclude that the increased level of feeding during the period of pregnancy contributes to an increase in the milk production of ewes by 13.8-32.1%. It was found that the optimal dose of increasing the nutritional value of the diet by 15% of the ewes showed the highest milk productivity, an increase of 20%, on the contrary, contributed to a slight decrease in milk productivity.

The enzymic degradation of wheat bran using cellulolytic and proteolytic enzymes from a number of sources was investigated. Two enzyme combinations were found to be effective for the chemical alteration of wheat bran. Crude enzyme preparation from the fungus T. viride in combination with a commercial proteinase brought about a 32% reducing sugar accumulation, a 36% loss of holocellulose, a 40% loss of α-cellulose and a, 54% solubilization of protein. Crude enzyme preparation from the fungus M. verrucaria in combination with a commercial proteinase gave rise to a 27% reducing sugar accumulation, a 39% loss of holocellulose, a 22% loss of α-cellulose and 50% solubilization of protein. The nutritional value for the rat of wheat bran modified by either enzyme combination was significantly improved. Apparent protein digestibility was improved significantly. Preliminary experiments indicate that the modification of wheat bran increases the metabolizable energy.

The influence of feeding high-performance cows of the energy feed additive Cobiotic Energy on the physiological state and productivity have been studied. Experiments have been carried out on with groups of dairy cows with 10 animals each during 55 days. The diet of cows of the first control group consisted of haylage of cereal and leguminous plants, corn silage, molasses, cereal hay, and feed of own production. 0.3 kg of feed additive has been introduced into the diet of animals of the experimental group II 15 days before calving, in the first 10 days after calving, as compensation for energy losses, 0.75 kg 3 times a day. In the next 30 days of the milking season with the ration of animals of the experimental group II, 0.25 kg of Cobiotic Energy has been fed, sprinkling it on top of the feed mixture. It has been established that the use of feed additives in the diets of cows has a positive effect on feed intake, physiological condition and animal productivity. It was determined that concentration of metabolizable energy in 1 kg of dry matter of the diet made 9–16– 9.2 MJ. The diet contained 12.8–13.0 % of crude protein per 1 kg of dry matter, the concentration of fiber in dry matter made 22.3– 22.0 %. The sugar-protein ratio made 1.04:1; 1.0. In terms of energy nutrition, the diet of the experimental group due to the inclusion of the feed supplement was 6 MJ higher, however, it slightly affected concentration of metabolizable energy of the diet. The energy-protein ratio corresponded to 0.2– 0.21. The nitrogen balance in the rumen was positive in all the animals and was at the level of 0.13–0.4 g. Feeding animals with supplement in the diet in the last 15 days of the dry period, during the first 10 days after calving and the next 30 days of the milking period promoted activation of protein biosynthesis and energy metabolism, as evidenced by an increase in serum total protein and its albumin fraction and ultimately increased animal productivity. The studied supplement use in the diets for cows makes it possible to increase performance of cows by 8.0 %, fat content by 0.1 %, protein by 0.24 %, lactose by 0.11 %, reduce the cost of feed for obtaining natural milk by 6.1%. Key words: feed supplement Cobiotic Energy, cows, diets, blood, milk yield, feed costs, milk quality.

Evaluation of the nutritional value of feed mixtures for lactation periods of the Ayrshire first-calf breed showed that in the first period there is an excess of dry matter and easily digestible protein in the diet, and a lack of sugar in all periods. The consumption of energy and nutrients for the synthesis of 1 kg of milk was optimal. For 305 days of lactation, an average of 7653 kg of milk per cow was obtained after the first calving, and the maximum daily milk yield was recorded in the second month of lactation. The research of lactation curves showed that highly productive cows have a more pronounced peak of milk yield in the first lactation months; the level of milk productivity remains high up to 9-10 months of the lactation period.

Жизненно важными микроэлементами для жвачных животных являются медь, цинк, марганец, железо, кобальт, йод, селен. Микроэлементы, в которых атом металла соединён и защищён белковыми молекулами, улучшают воспроизводительные качества самок за счёт повышения оплодотворяемости, уменьшения эмбриональной смертности, улучшения состояния мочеполовой системы или повышения интенсивности функционирования яичников. Поэтому в настоящее время актуальными являются разработка и внедрение в технологию кормления сельскохозяйственных животных наиболее эффективных препаратов с необходимыми биологически активными веществами. На основании проведённого исследования дано практическое обоснование использования в технологии кормления тёлок отечественной кормовой биодобавки на основе гидролизата соевого белка, витаминов и микроэлементов. Установлено её положительное действие на некоторые функции органов и систем животных. Экспериментально доказана эффективность её применения для оптимизации обменных процессов и повышения воспроизводительных функций тёлок. Так, биохимическим исследованием образцов крови подопытных животных установлено, что количество кальция и фосфора в крови у тёлок опытной группы по сравнению с контролем было достоверно выше на 2,35 и 2,9% соответственно. Эритропоэтическая фракция была более выражена у молодняка опытной группы. У тёлок опытной группы время от начала скармливания препарата до первой выраженной охоты и осеменения, по сравнению с контрольными животными, сократилось на 16%, а период от начала скармливания препарата до плодотворного осеменения – на 25,7%. Количество тёлок, пришедших в охоту и осеменённых в первый месяц, в опытной группе по сравнению с контрольной было на 43% больше. Оплодотворяемость тёлок опытной группы за учётный период составила 95%, что на 20% больше, чем у животных контрольной группы. Включение в рацион тёлок биодобавки в дозе 100 мл/гол. позволило получить дополнительно на 8,5% больше валового прироста живой массы по отношению к их аналогам. The vital trace nutrients for ruminants are copper, zinc, manganese, iron, cobalt, iodine, selenium. Microelements in which a metal atom is jointed and protected by protein molecules improve the reproductive qualities of females by increasing fertility, reducing embryonic mortality, improving the state of the genito-urinary system or increasing the intensity of ovarian functioning. Therefore the development and implementation of the most effective preparations with the necessary biologically active substances in the technology of feeding farm animals is currently relevant. On the ground of conducted research a practical substantiation of the use of domestic food supplement based on the hydrolyzate of soy protein, vitamins and trace nutrients in the feeding technology of heifers is given. Its positive effect on some functions of animal organs and systems has been established. The effectiveness of its application to optimize metabolic processes and increase the reproductive functions of heifers has been experimentally proven. Thus a biochemical blood samples analysis of experimental animals found that the amount of calcium and phosphorus in the blood of the heifers of the experimental group compared with the control was significantly higher by 2.35 and 2.9% respectively. The erythropoietic fraction was more defined in the young experimental group. In heifers of the experimental group the time from the beginning of feeding the drug to the first defined heat and insemination compared with control animals decreased by 16% and the period from the beginning of feeding the drug to prolific insemination – by 25.7%. The number of heifers that came to the heat and inseminated in the first month in the experimental group was 43% higher than the control group. The impregnation capacity of the heifers of the experimental group during the record period was 95% which is 20% more than in animals of the control group. Inclusion in the diet of heifers bioadditive at a dose of 100 ml / goal allowed obtaining additionally 8.5% more the gross body weight gain relative to their analogs.

It is the fact with the introduction of the detailed system of normalized feeding in the livestock industry, the productivity of farm animals has increased by 11,2 %. The obvious solution to the problem of feeding pigs with complete feed is seen in the use of feed and feed additives of local production, which will reduce the final prime cost of the product. The purpose of the work was to justify the use of feed additives Nabikat and Glauconite in feeding sows. During the experiment 3 groups of sows have been formed (a control group and two experimental ones). Sows of the control group have been received the main farm diet, sows of the 1st experimental group in addition to the main diet have been received the feed additive Nabikat (0,20 % of the dry matter of the diet), and the 2nd experimental group Glauconite (0,25 % of the dry matter of the diet). It has been found on the base of researches that the input of the feed additive Nabikat in the diet of pregnant sows has increased the prolificacy of sows by 16,3 %, the livability of piglets by 10,9 %, while the expenditures of feed has been reduced by 20,4 %. The lowest feed and digestible protein expenditures per live weight gain of a pregnant sow and a weaning piglet have been observed in the 1st experimental group when the feed additive Nabikat was included in the diet of sows. The highest feed payment for 1 weaned piglet has been observed when feeding the feed additive Nabikat to sows, which allows producing 24,3 heads of piglets in natural terms, in monetary terms of 1,92 heads. At the same time, it is possible to get an additional profit of 6,9 thousand rubles.
