ASSESSING EFFICIENCY OF THE CONIFEROUS ENERGY SUPPLEMENT IN THE DIET OF DAIRY COWS FOR MAINTAINING PRODUCTIVE HEALTH

  Objective: This study was aimed at assessing efficiency of the original coniferous energy supplement in the diet of cows at the end of the dry period - beginning of lactation - for improving the energy density of diets, enriching them with vitamins and major and minor nutrient elements, improving milk productivity, and maintaining productive health.Methods: The scientific-production experiment was performed on the basis of the Lukoshkino†unit of the Klenovo-Chegodaevo†research farm (Moscow) on twenty cows. The preparation was fed at the rate of 150 g for 20 days before calving and for 30 days after calving.Results: Studies have found the positive effect of the preparation on the average daily milk yield, natural fat content increased by 5.4%-6.9% (with butterfat percentage increased by 0.09%), and reduced cost of feed per unit of obtained product.Conclusion: The use of the preparation promoted enzymatic processes in the rumen, had positive effect on the carbohydrate-lipid and protein metabolism, and had no negative effect on the non-specific resistance of cows

Биохимические Показатели Крови Телят при Применении Галеновых Препаратов на Основе Биополимеров

The article discusses the issues about the effect of the energy coniferous flax stimulator on the blood chemistry values of calves. Every day for 14 days, bulls of two experimental groups (second and third groups) received the drug at the doses of 150 ml and 200 ml, respectively. The animals in the reference group did not receive the drug. When analyzing biochemical parameters, it has been established that the concentration of phosphorus in the blood of the experimental calves prior to the experiment was significantly below the normal level. The use of the drug has significantly increased the phosphorus level in the blood of the experimental calves. The AST/ALT ratio in the animals before the experiment exceeded the normal levels, whereas the use of the galenical preparation normalized this indicator. It has also been established that the drug provides the normalization of the calcium-phosphorus ratio.рассматриваются вопросы о влиянии препарата «Энергетический хвойно-льняной стимулятор» на биохимические показатели крови телят. Ежедневно на протяжении 14 суток бычки 2-х опытных групп (2-я и 3-я группы) получали препарат в дозах 150 мл и 200 мл соответственно. Животные контрольной группы препарат не получали. При анализе биохимических показателей установлено, что концентрация фосфора в крови подопытных телят до опыта была существенно ниже уровня нормы. Применение препарата достоверно повысило уровень фосфора в крови опытных телят. Коэффициент де Ритиса у животных до опыта превышал уровни нормы, применение галенового препарата нормализует этот показатель. Установлено также, что препарат приводит к нормализации кальций фосфорного соотношения
