文章旨在分析不同水平杜仲提取物对妊娠母猪繁殖性能、泌乳性能及后代仔猪生长性能的影响。试验选择体况、日龄、体重、胎次(1 胎)及预产期等相近的妊娠 90 d的"长×大"二元母猪 60 只作为试验动物，随机分成 4组，每组 15 个重复，每头妊娠 90 d的"长×大"二元母猪为 1 个重复组，组别分别在基础日粮中添加 0(1 组)、1。0%(2 组)、2。0%(3 组)、3。0%(4 组)杜仲提取物，从试验用妊娠母猪 90 d开始饲喂至哺乳期 21 d试验结束，试验为期46 d。结果表明:(1)与试验 1 组相比，试验 3、4 组母猪的产活仔数、初生活仔猪均重显著提高 13。2%、13。3%、8。3%、9。1%(P＜0。05);(2)与试验 1 组相比，试验 3、4 组母猪乳汁的乳脂率、乳糖率显著提高 7。6%、7。9%、11。0%、11。2%(P＜0。05)，其背膘厚度损失显著降低 7。2%、8。1%(P＜0。05);(3)与试验 1 组相比，试验 3、4 组断奶仔猪均重、平均日增重显著提高 8。3%、8。8%、13。9%、16。7%(P＜0。05)，其断奶仔猪腹泻率显著降低 39。4%、39。6%(P＜0。05)。综上所述，不同水平杜仲提取物可提高妊娠母猪繁殖性能、泌乳性能及后代仔猪生长性能，综合使用成本以基础日粮中添加 2。0%杜仲提取物效果较好，可以在生产中推广应用。
Effects of eucommia ulmoides extract on reproductive performance,lactation performance,and growth performance of sows and piglets
To analyze the effects of different levels of Eucommia ulmoides extract on reproductive performance,lactation performance,and growth performance of pregnant sows and offspring piglets.This experiment selected 90 day pregnant women with similar physical condition,age,weight,parity(1 fetus),and expected delivery 60"Date×Large"binary sows were randomly divided into 4 groups as experimental animals,with 15 replicates in each group.Each group had a 90 day gestation of the"Date×Large"big binary sows were a repeated group,with 0(group 1),1.0%(group 2),2.0%(group 3),and 3.0%(group 4)of Eucommia ulmoides extract added to the basic diet.The experimental sows were fed from the 90th day of pregnancy until the end of the lactation period of 21 days,with a trial period of 46 days.The results showed that:(1)the number of live piglets produced and the average weight of piglets in groups 3 and 4 were significantly increased by 13.2%,13.3%,8.3%,and 9.1%compared to group 1(P＜0.05);(2)The milk fat rate and lactose rate of Group 3 and Group 4 were significantly increased by 7.6%,7.9%,11.0%,and 11.2%compared to Group 1(P＜0.05),and their back fat thickness loss was significantly reduced by 7.2%and 8.1%compared to Group 1(P＜0.05);(3)The average weight and daily gain of weaned piglets in Experiment 3 and Group 4 were significantly increased by 8.3%,8.8%,13.9%,and 16.7%compared to Group 1(P＜0.05),and the diarrhea rate of weaned piglets was significantly reduced by 39.4%and 39.6%compared to Group 1(P＜0.05).In summary,the addition of different levels of Eucommia ulmoides extract can improve the reproductive performance,lactation performance,and offspring growth performance of pregnant sows.Among them,adding 2.0%Eucommia ulmoides extract to the basic diet has a better effect and can be promoted and applied in clinical practice.
