酵母培养物益康"xp"对母猪繁殖性能的影响

选取80头临产前28~35 d的妊娠母猪,根据品种相同、胎次相近的原则将其随机分为对照组和试验组。从母猪怀孕后期(怀孕85 d左右)开始至哺乳期结束,研究在其日粮中添加酵母培养物益康“xp”对母猪繁殖性能的影响,怀孕后期和哺乳期益康“xp”的添加量分别为0.25%和0.3%。结果表明,试验组母猪的窝产仔总数、窝产活仔数比对照组均有不同程度提高,其中窝产活仔数提高了10.90%,显著高于对照组(P<0.05);试验组仔猪的死胎率、弱仔率、畸形率和木乃伊率比对照组均有不同程度下降;仔猪20日龄窝重、窝断奶仔猪数、平均断奶重、断奶窝重也不同程度高于对照组,其中窝断奶仔猪数提高了10.63%,显著高于对照组(P<0.05)。

Effect of Yeast Culture Yikang "xp" on Reproductive Performance of Sows

80 gestation sows 28 to 35 days prior to farrowing were divided randomly into control and treatment groups to study the effect of yeast culture Yikang"xp" on the reproductive performance of sows.Yikang"xp" was supplemented to the diet of sows from 85 days after gestation and for the duration of lactation.The results showed that Yikang"xp" could improve the litter size and alive litter size of sows,the alive litter size was improved by 10.90% compared with the control group,the difference was statistically significant(P<0.05).Still the birth rate,weakling piglet rate,deformity rate and mummy rate were decreased in the treatment group.The litter weight at 21 d,pig weaned/litter,pig weaning weight and litter weaning weigh were improved compared with the control group.The pig weaned/litter was improved by 10.63%,the difference was statistically significant(P<0.05).
