Научно-хозяйственный опыт по изучению эффективности использования кормовой добавки для воспроизводящего состава и жеребцов-производителей проведён в МИП «Меркурий» Амгинского улуса Республики Саха (Якутия) в феврале-марте 2019 года в местах тебенёвки во время подкормки. Рецептуры кормовых добавок для лошадей якутской породы разработаны на основе определения дефицита энергии, питательных и минеральных веществ в сене и тебенёвочном корме, проведены расчёты потребности кобыл и жеребцов-производителей в протеине, минеральных веществах и витаминах. При потреблении 11,07–12,8 кг сухого вещества сено-овсяного рациона жерёбые кобылы и жеребцы-производители испытывали дефицит практически во всех основных питательных веществах, за исключением сырой клетчатки, кальция и магния. Скармливание жерёбым кобылам и жеребцам-производителям кормовых добавок скорректировало минеральный, аминокислотный, витаминный обмен, положительно сказалось на биохимическом статусе крови, обмене веществ и энергии. Наибольшее поступление валовой энергии в организм отмечалось у кобыл и жеребцов-производителей опытных групп: они превосходили по данному показателю аналогов контрольных групп на 2,1% (173,85 ± 6,11 МДж) и 1,6% (179,82 ± 8,14 МДж) соответственно. В результате меньших потерь энергии с калом, мочой и метаном у жерёбых кобыл опытной группы достоверно выше оказалось её усвоение. Так, обменная энергия у жерёбых кобыл опытной группы была на 8,52% достоверно выше и составила 104,52 ± 1,08 МДж, у аналогов контрольной группы обменная энергия составила 96,31 ± 1,17 МДж (Р ≥ 0,95). У жеребцов-производителей опытной группы преимущество по величине изучаемого показателя над контролем составило 4,38% (107,68 ±9,44 МДж). Лучшее переваривание и использование энергии кормов способствовало повышению обменности валовой энергии у кобыл опытной группы на 3,55%, у жеребцов-производителей опытной группы — на 0,93% по сравнению с аналогами контрольных групп и составила у опытных кобыл 60,12%, у опытных жеребцов-производителей — 59,8%. The experiment was conducted at the MIP “Merkuriy”, the Republic of Sakha (Yakutia), in February-March of 2019. The investigation tested the effect of feed additives on Yakutian horses in the period of winter grazing. The compositions of feed additives were developed to supply animals with sufficient energy, nutrients and minerals lacking in hay and winter forage. Additionally, protein, mineral and vitamin requirements were analyzed. Horses fed with 11.07–12.8 kg of hay and oat dry matter suffered from deficiency in essential nutrients, except for crude fiber, Ca, and Mg. Feed additives optimized mineral, amino acid, and vitamin metabolisms as well as positively affected blood biochemistry, chemical reactions, and energy transformation. Horses obtained more gross energy via feed additives exceeding the control groups by 2.1 (173.85 ± 6.11 MJ) and 1.6% (179.82 ± 8.14 MJ). Pregnant mares had lower energy losses. They received 104.52 ± 1.08 MJ of exchange energy, significantly exceeding the control group by 8.52% (Р ≥ 0,95). Stallions exceeded the control group by 4.38% (107.68 ± 9.44 MJ) in the same parameter. Better forage digestibility and energy supply led to more effective transformation of gross energy into exchange energy: by 3.55% for mares (60.12%) and 0.93% — for stallions (59.8%).

One of the main branches of agriculture in the Republic of Sakha (Yakutia) is productive horse breeding. In this regard, we can use the valuable raw materials that the horse gives due to its high adaptability to local conditions. The development of productive horse breeding in particular dairy horse breeding under the conditions of the Republic of Sakha (Yakutia) would allow providing the population with natural, dietary food and more efficient use of land resources. The purpose of the work is to study the effect of zeolite and zeolite-sapropel feed additives in the ration of mares of Megezhek breed on the milk productivity and quality of kumiss under the conditions of Central Yakutia. Two scientific and economic experiments have been carried out where the influence of zeolite from the Suntar deposit (experiment 1) and zeolite-sapropel feed additives (experiment 2) on the milk productivity and physiological parameters of mares of Megezhek breed has been studied. The optimal doses of the effect of zeolite and zeolite-sapropel feed additives on the profi tability of kumiss production have been determined. It has been found in the first scientific and economic experiment that when adding 0,4 g of zeolite per 1 kg of live weight to the daily ration of lactating mares the level of profi tability of milk production increased to 20,4 %, and when adding 0,5 g per 1 kg of live weight the profi tability index increased to 21,5 %, compared to 13,7 % in the control group. In the second scientific and economic experiment the infl uence of the zeolite-sapropel feed additive on the intensity of digestion and assimilation of nutrients in the mares’ rations has been determined. The analysis of the experimental data indicates a high economic efficiency of using zeolite-sapropel feed additive in the 2nd and 3rd experimental groups of mares, where the level of profi tability of production was equal to 27,34 and 32,33 %, respectively, compared to 16,09 % in the control group.

1. An experiment was conducted in which sodium and calcium salts of acetic, propionic and butyric acids were given to groups of eight lambs as additions to basal diets of hay and concentrate. Two control groups were included, one group which received only the basal ration and one high-level control group which received sufficient additional concentrate to achieve growth rates greater than those of the groups receiving volatile fatty acid (VFA) salts. 2. With rumen-fistulated sheep, the effect on the rumen VFA composition and the pH of the rumen liquor, of diets supplemented with VFA salts given twice daily, was also investigated and compared with the effect of the basal diet alone. 3. The lambs receiving the VFA salts grew faster and achieved significantly greater empty body and carcass weights than those receiving only the basal rations; the high-level control group had significantly greater empty body and carcass weights than groups receiving salts of VFA. 4. There were no differences approaching significance in the efficiency of the three VFA in promoting gains in live weight, empty body weight and carcass weight. There appeared to be equal efficiency of utilization of the gross energy of the VFA and of the calculatedmetabolizable energy of the concentrates. 5. The effect of twice-daily feeding on the rumen VFA composition was that the concentration of the supple- mentary acid was greatest shortly after feeding, and about 5–6 h after feeding the effect was difficult to detect. There were no differences in the pH of the rumen liquor between animals given diets containing VFA salts and those given the basal ration.

A series of scientific and economic experiments have already been conducted to determine the norms for including local non-traditional feed additives in the rations of cattle, but they were not sufficient for the rational use of these feed additives. In order to determine the effectiveness of the use of local feed additives a scientific and economic experiment has been carried out under the environments of the APC “Krestyakh” in the Suntarsky district. Two groups of first-calf heifers have been selected per 50 heads in each. The groups have been formed by using the method of analogues. The environments of housing in all groups have been the same. The difference was that the experimental group of first-calf heifers have received from the local unconventional feed additives (zeolite khongurin, sapropel and Kempendyaskay salt). The results of the production test have shown that the experimental group of first-calf heifers exceeded the control group’s analogues in terms of milk yield by 233,4 kg or 9,4 %. Experimental group of first-calf heifers has had more high content of fat in milk 0,17 abs.%. When recalculating the content of fat in milk for 4 %, the difference in gross milk yield between the groups was 16,73 t or 14,3 % in favor of the experimental group. Economic analysis of the results of research and production experiment has shown that there was a significant difference in profit between the groups. So, in the control group it was 462 247,46 rubles, and in the experimental group 528 444,43 rubles. Additional profit in the experimental group was equal to 66 196,97 rubles, while the level of profitability was 8,2 %. Thus, the results of the research have shown that first-calf heifers of Simmental breed that received local non-traditional feed additives had higher milk productivity.

Целью исследований являлось определение эффективности производства молока при внедрении местных нетрадиционных кормовых добавок в кормлении первотелок красной степной породы. Научно-производственных опыт был проведен в условиях сельхозкооператива Республики Саха (Якутия). По методу аналогов были сформированы опытная и контрольная группы. В период проведения производственного опыта первотелки контрольной группы потребляли основной рацион. Первотелки опытной группы дополнительно к основному рациону получали на 1 голову цеолит в дозе 1 г на 1 кг живой массы, 300 г сапропеля и 60 г Кемпендяйской соли. При включении местных нетрадиционных кормовых добавок в рацион первотелок отмечено улучшение молочной продуктивности. В опытной группе на производство 1 кг молока было затрачено 1,48 ЭКЕ против 1,67 в контрольной группе. При сравнении среднесуточного удоя отмечена разница в контрольной группе 7,73 кг, в опытной — 8,58 кг молока, при этом валовое производство молока составило 127185 и 141215 кг, соответственно. Включение местных нетрадиционных кормовых добавок в состав рациона первотелок способствовало повышению молочной продуктивности на 10,09%. При изучении экономической эффективности внедрения местных нетрадиционных кормовых добавок в кормлении первотелок было установлено, что в опытной группе животных было дополнительно получено 653,5 тыс. руб. при дополнительных затратах 19,8 тыс. руб. Таким образом, использование местных нетрадиционных кормовых добавок в кормлении первотелок способствует повышению молочной продуктивности. The aim of the research was to determine the efficiency of milk production when introducing local non-traditional feed additives in the feeding of heifers of the red steppe breed. Scientific experience was carried out in the conditions of the Agricultural Production Cooperative "Crosses" of the Suntarsky district of the Republic of Sakha (Yakutia). To conduct the experiment, the experimental and control groups were formed by the method of analogues. During the production experience, the control group first calves consumed the main diet. An experimental group of heifers in addition to the main diet received zeolite per 1 head in a dose of 1 g per 1 kg of live weight, 300 g of sapropel and 60 g of Kempendiai salt. When local non-traditional feed additives were included in the feeding of heifers, there was an improvement in milk productivity, so in the experimental group of animals 1.48 energy feed units were spent on the production of 1 kg of milk compared to 1.67 in the control group. When comparing the average daily milk yield, the difference in the control group was 7.73 kg, and in the experimental group 8.58 kg of milk, while the gross milk production was 127185 and 141215 kg, respectively. The inclusion of local non-traditional feed additives in the diet of heifers contributed to an increase in milk productivity by 10.09%. When studying the economic efficiency of introducing local non-traditional feed additives in the feeding of heifers, it was found that 653.5 thousand rubles were received in the experimental group of animals. at additional costs 19.8 thousand rubles. Thus, the use of local non-traditional feed additives in feeding heifers contributes to an increase in milk productivity.

Conjugated linoleic acid (CLA) is a collective term for the positional and geometric isomers of a conjugated diene of linoleic acid (C18:2, n-6). The aims of the present study were to evaluate whether levels of hepatic α-tocopherol, α-tocopherol transfer protein (α-TTP), and antioxidant enzymes in mice were affected by a CLA-supplemented diet. C57BL/6 J mice were divided into the CLA and control groups, which were fed, respectively, a 5 % fat diet with or without 1 g/100 g of CLA (1:1 mixture of cis-9, trans-11 and trans-10, cis-12) for four weeks. α-Tocopherol levels in plasma and liver were significantly higher in the CLA group than in the control group. Liver α-TTP levels were also significantly increased in the CLA group, the α-TTP/β-actin ratio being 2.5-fold higher than that in control mice (p<0.01). Thiobarbituric acid-reactive substances were significantly decreased in the CLA group (p<0.01). There were no significant differences between the two groups in levels of three antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). The accumulation of liver α-tocopherol seen with the CLA diet can be attributed to the antioxidant potential of CLA and the ability of α-TTP induction. The lack of changes in antioxidant enzyme protein levels and the reduced lipid peroxidation in the liver of CLA mice are due to α-tocopherol accumulation.
