摘要
文章旨在研究发酵饲料对母猪繁殖性能、泌乳性能和仔猪生长性能的影响,试验将60头健康美系大白母猪随机分成3组(对照组、发酵饲料1组、发酵饲料2组),对照组饲喂基础饲料,发酵饲料1组和发酵饲料2组分别饲喂含4.5%发酵饲料原料的发酵饲料1和含9%发酵饲料原料的发酵饲料2。结果表明,与对照组相比,发酵饲料2组母猪产活仔数、初生仔猪均重、母猪乳汁乳脂率、乳糖率、断奶活仔数、断奶仔猪均重、仔猪平均日增重分别显著提高7.66%、3.62%、7.37%、8.25%、8.80%、6.84%、7.41%(P<0.05),仔猪腹泻率、母猪背腰厚度损失分别显著降低51.22%、7.80%(P<0.05)。说明由复合益生菌发酵饲料原料制备的含9%发酵饲料原料的发酵饲料能显著提高妊娠母猪繁殖性能、哺乳母猪泌乳性能和仔猪生长性能。
In order to study the effect of fermented feed on reproductive performance,lactation performance and growth performance of piglets,Forty healthy American white sows were randomly divided into three groups(Control group,fermented feed group 1,fermented feed group 2),the control group was fed with basic feed,the fermented feed group 1 and fermented feed group 2 were fed with fermented feed 1 containing 4.5%and 9%of fermented feed raw materials.The results showed that the fermented feed group 2 compared with control group,the number of live sows,the average weight of newborn piglets,the milk fat rate,the number of live weaned piglets,the average weight of weaned piglets,the average daily weight gain of piglets increased by 7.66%,3.62%,7.37%,8.25%,8.80%,6.84%and 7.41%(P<0.05),and the diarrhea rate of piglets,the loss of sow’s back waist thickness decreased by51.22%and 7.80%(P<0.05).It indicated that the fermented feed containing 9%fermented feed materials prepared from compound probiotics fermented feed materials can significantly improve the reproductive performance of pregnant sows,lactation performance of lactating sows and growth performance of piglets.
