基础日粮添加蜂胶对母猪生产性能的影响

Effects of Basal Diet with Propolis on Production Performance of Pregnant Sows

为了研究蜂胶对母猪生产性能的影响,选择16头配种时间、胎次基本一致的长大妊娠母猪为材料,随机分成对照组和试验组。对照组只饲喂基础日粮,试验组则在基础日粮中添加蜂胶。试验从母猪妊娠81d进产房开始,到仔猪21日龄断奶后7d结束。研究结果表明,与对照组相比,试验组仔猪断奶重平均提高0.62kg,差异极显著(P<0.01);成活率提高4.51%,差异显著(P<0.05);在哺乳和断奶前7d,试验组仔猪腹泻率分别比对照组低1.37%(P<0.05)、2.96%(P<0.01)。因此,蜂胶对提高母猪生产性能有较大促进作用。

In order to study the effect of propolis on production performance of sows, sixteen pregnant sows （Landrance ×Yorkshire） whose mating date and parity were similar were selected and randomly assigned into control group and treated group. The control group were only fed with the basal diet, while the treated group were fed with the basal diet added with propolis. The test began when sows with 81 days of gestation were moved into farrowing house and ended when 21 days piglets had been weaned for 7 days. Results showed that compared with control, the average gain of weaning piglets in treated group was improved by 0.62 kg （P〈0.01）, and the survival rate was improved by 4.51% （P〈0.05）. In the lactation and 7 days before weaning, the diarrhea incidence of piglets in treated group was decreased by 1.37% （P〈0.05） and 2.96% （P〈0.01）, respectively. Therefore, propolis can improve the production performance of sows greatly.
