卵磷脂对母猪育仔性能的影响

探讨卵磷脂在哺乳母猪上的应用效果,为卵磷脂应用于哺乳母猪提供理论支持.试验设4个处理组,第Ⅰ组喂给基础日粮,第Ⅱ、Ⅲ、Ⅳ组分别在基础日粮中添加4%豆油,4%OP磷脂,4%卵磷脂 4%豆油.结果表明:各添加组都显著提高了20日龄、28日龄仔猪窝重(p<0.05),且显著提高了20日龄母猪泌乳量(P<0.05),混合添加组作用极显著;只有混合添加组显著降低了泌乳期母猪失重(p<0.05),且使母猪断奶后至发情间隔显著缩短于对照组(p<0.05);各添加组均降低了仔猪死亡卒.

Effect of Lectine on Producing Piglet Performance of Sow

In the experiment effect of lectine on lactating sow was studied, in order to provide theoretical help for lectine used in lactating sow. Effect of different supplemental level of lectine on lactating sow were studied.The results as follows: All of the adding groups increased the cote weight of piglet of laecating sow both at 20 days old and 28 days old (p<0.05), and increased the lactation of laecating sow at 20 days old (p<0.05). Only the group of adding 4% lectine + 4% oil decreased the weigh lose of laecating sow (p<0.05) and decreased the interval from weaning to oestrus (p<0.05), the survival rate of adding groups was higher than that of control group.
