【摘要】 将24头长×大二元母猪随机分为4组,每组6头,以研究半乳甘露寡糖添加在2种营养水平日粮中对其泌乳性能和血清激素水平的影响。结果表明:当母猪饲粮营养水平相同时,添加GMOS与未添加组相比,可以显著提高母猪的泌乳量、降低料乳比,对内分泌机能也有一定的调节作用。更多还原

【Abstract】 Twenty-four sows(Landrace × Yorkshire) were randomly divided into 4 groups with 6 replicates in each and 2 diets differing in nutritional level were enriched with GMOS(galacto-mannan-oligosaccharides) to study the effects of GMOS on their lactating performance and serum hormones.With the same nutritional level in the diet,GMOS significantly increased milk yield of the sows and decreased feed/milk ratio and showed some regulatory effect on the endocrine mechanism.更多还原
