Воспроизводительные функции свиноматок при использовании в рационе фермента Сель Ист и глауконита

Воспроизводительные функции свиноматок при использовании в рационе фермента Сель Ист и глауконита

Abstract

Изложены результаты исследований эффективности использования в рационах супоросных и подсосных свиноматок, а также поросят молочного периода выращивания, кормовой добавки глауконита в количестве 0,25 % от сухого вещества рациона и фермента Сель Ист в дозе 1 кг/т комбикорма. Кормовая добавка глауконит, в сравнении с контрольной группой, позволила повысить среднесуточный прирост живой массы супоросных свиноматок на 5,1 %, фермент Сель Ист - на 7,0 %, при совместном их использовании - на 9,0 %, получить многоплодие свиноматок соответственно 10,8, 11,0 и 11,5 гол., в сравнении с контрольной группой, у которой оно было на уровне 10,5 гол. Среднесуточный прирост живой массы поросят, получавших изучаемые кормовые добавки с 11-го дня подсосного периода, как и их матери, превосходил аналогов контрольной группы на 8,6 % в группе с глауконитом, на 9,1 % - с ферментом Сель Ист и на 12,4 % - при совместном их скармливании. Если сохранность поголовья поросят в контрольной группе была на уровне 88,6 %, то в группе с глауконитом она возросла до 91,2 %, с ферментом Сель Ист - до 90,2 % и при совместном скармливании - до 91,3 %. При затратах корма на одного поросенка отъемного возраста в контрольной группы 49,59 кг комбикорма, 62,90 - ЭКЕ и 5,65 кг переваримого протеина, в опытных группах при одинаковых затратах переваримого протеина, расход комбикорма и энергии снизился на 1,5-2,1 % в группе с кормовой добавкой глауконита, на 2,6-3,0 % - с ферментом Сель Ист и на 6,3-6,5% - при их совместном использовании.

It presents the results of effectiveness research of use in diets of pregnant and lactating sows as well as suckling piglets a dairy feed additive of glauconite in the amount of 0.25 % of the diet dry substance and enzyme Sel East at 1 kg/ton of fodder. The glauconite feed additive in comparison with the control group allowed to increase the average daily live weight gain of pregnant sows by 5.1 %, the enzyme Sel East by 7.0 %, when used together by 9.0 %, and to get a farrow respectively of 10.8, 11.0 and 11.5 heads in comparison with the control group, in which it was 10.5 heads. In this case, the average daily live weight gain of piglets fed with the discussed feed additives from the 11 days of a suckling period, as well as their mother exceeded the analogs of the control group by 8.6 % in the group with glauconite, by 9.1 % with enzyme Sel East and 12.4 % when both were given. If the safety of a livestock of piglets in the control group was at the 88.6 % level, in the group with glauconite it increased to 91.2 %, with enzyme Sel East up to 90.2 %, and a co-fed up to 91.3 %. With a fodder cost of 49.59 kg, 62.90 kg of EFU and 5.65 kg of a digestible protein per a piglet of a weaned age in the control group, the experimental groups showed a decrease of fodder and energy consumption by 1.5-2.1 % with the glauconite feed additive, 2.6-3.0 % with the enzyme Sel East and 6.3-6.5 % when co-used at the same cost of a digestible protein.
