В ходе эксперимента было выявлено влияние различных (высоко-, умеренно – и низкоконцентрированных) типов кормления стельных коров на последующую продуктивность, переваримость питательных веществ, продолжительность сервис – периода, масса телят при рождении, клинические и гематологические показатели животных. В результате исследований калориметрического, жидкостного и газожидкостного хроматографического, атомно-адсорбционного методов определяли качество и химический состав кормов, согласно данным разработали рационы для стельных сухостойных коров. Рефрактометрическим методом выявляли физико-биохимические показатели крови. Уровень кормления стельных сухостойных коров показало, что от высококонцентрированного типа (40%) было получено 6100 кг молока за лактацию, что на 5,1 % по отношению к умеренноконцентрированному и на 9,3% больше к уровню низкоконцентрированному. | In the course of the experiment there was revealed the effect of different (high, moderate and low concentrated) types of feeding of pregnant cows on subsequent productivity, digestibility of nutrients, duration of service period, calves weight at birth, clinical and hematological indicators of animals. As a result of studies of calorimetric, liquid and gas-liquid chromatography, atomic-absorption methods we determined the quality and chemical composition of feed, according to the data we developed the rations for pregnant dry cows. Physico-biochemical indicators of blood were determined by refractometric method. The level of feeding of pregnant dry cows have shown that there was obtained 6100 kg of milk from highly concentrated type (40%) during the lactation, which is by 5,1% more in relation to moderately concentrated and by 9,3% more compared to the low concentrated level.

triglycerides by 12,2…19,5%, during the first fattening period and by 34,5…51,7% during the second fattening period, which indicates more intensive fat deposition. The optimization of lipid metabolism in blood serum of pigs when included in the rations of feed additives allowed to reduce the age of reaching by them live weight of 100 kg by 9 days with the «Omega-3 Aktiv» inclusion and by 23 days with the «Polysol omega-3» compared to the control group. Thus, the use feed additives in diets of fattening pig in the form of polyunsaturated fatty «Omega-3 Aktiv» and «Polisol Omega-3» acids helps to optimize lipid metabolism and assimilation processes in the body overall which positively affects their growth, development and maturing rate. | липопротеидов высокой плотности на 7,9…22,5 %
