Целлобактерин в рационах бычков и баранчиков

Abstract

For the purpose of studying of efficiency of application of a probiotics zellobacterin in compound feeds for ruminants 2 scientific and economic experiences are carried out: the first on the fattened bull-calves, the second on lambs. In experience on bull-calves there were 3 groups, on lambs 2 groups. The preparation was set to bull-calves of skilled groups of calculation of 0,2 % (2 skilled group) and 0,5 % (3 skilled group) a probiotics from amount of set compound feed, and lambs of skilled group consumed 0,5 % zellobacterin from amount of compound feed in a diet. It is established that the additive of 0,2 % zellobacterin from weight of compound feed for bull-calves and 0,5 % for lambs raises a to digest of all nutrients of diets, especially celluloses (at bull-calves for 3,3 %, at lambs on 5,3 %), daily body gains masses of a body for 8,91-8,98 %, meat and wool efficiency, quality of meat and wool, during too time decrease costs of forages of 1 kg of a gain of weight of a body at bull-calves on 6,3 MDj, at lambs on 4,0 MDj. For efficiency increase feeding bull-calves and lambs it is recommended to include in composition of compound feed respectively 0,2 and 0,5 % zellobacterin from weight of a consumed forage.

С целью изучения эффективности применения пробиотика целлобактерин в комбикормах для жвачных животных проведено 2 научно-хозяйственных опыта: первый на откармливаемых бычках, второй на баранчиках. В опыте на бычках было 3 группы, на баранчиках 2 группы. Препарат задавали бычкам опытных групп из расчета 0,2 % (II опытная группа) и 0,5 % (III опытная группа) пробиотика от количества комбикорма, баранчики опытной группы потребляли 0,5 % целлобактерина от количества комбикорма в рационе. Добавка 0,2 % целлобактерина от массы комбикорма для бычков и 0,5 % для баранчиков повышает переваримость всех питательных веществ рационов, особенно клетчатки (у бычков на 3,3 %, у баранчиков на 5,3 %), суточные приросты массы тела (на 8,91.8,98 %), мясную и шерстную продуктивность, качество мяса и шерсти, снижают затраты кормов на 1 кг прироста массы тела у бычков на 6,3 МДж, у баранчиков на 4,0 МДж. Для повышения эффективности откорма бычков и баранчиков рекомендуется включать в рационы соответственно 0,2 и 0,5 % целлобактерина от массы потребляемого комбикорма
