寡糖取代抗生素对母猪泌乳量和乳成分的影响

将24头长×大二元母猪随机分为4组,每组6头,研究同一玉米-豆粕型基础日粮中分别添加20mg/kg吉它霉素、20mg/kg维吉尼亚霉素和0.10%半乳甘露寡糖对母猪泌乳量和乳中常规成分的影响。结果表明,半乳甘露寡糖可以增加母猪的泌乳量,提高乳中蛋白质、总固形物和非脂物质的含量,是一种有效的母猪饲料添加剂。

Effect of oligosaccharides substituting for antibiotics on milk yields and conventional ingredients in milk of sows

Twenty-four sows (Landrace×Yorkshine) were randomly allocated to four groups with six in each. All of pigs were fed with the same basal corn-soybean meal diet, and the four groups include the control group, the Kita group with 20 mg/kg kitasamycin , the Vigi group with 20 mg/kg virginiamycin and the GMOS group with 0.10% galacto-mannan-oligosaccharides. The study was to determine the effects of the three additives on milk yields and conventional ingredients in milk. Our results indicate that dietary supplementation with GMOS is effective in enhancing milk yields and increase the concentration of proteins, total solids and materials exclude fat in sow's milk. It is a kind of effective sow feed additive.
