复合植物提取物对妊娠母猪繁殖性能的影响

Effects of compound plant extracts on reproduction performance of pregnant sows

为研究复合植物提取物对妊娠母猪繁殖性能的影响,试验选取40头妊娠85 d大长二元母猪,随机分为对照组、植物提取物组(1000 mg/kg),每头猪为一个重复,试验期为妊娠85 d至分娩。结果表明:植物提取物组仔猪初生重较对照组提高7.6%(P<0.05),并且植物提取物组高初生重仔猪的比例增加(P<0.01),低初生重仔猪的比例减少(P<0.05)。综上,复合植物提取物可提高仔猪初生重,改善仔猪均匀度,提高母猪的繁殖性能。

To study the effect of compound plant extracts added to sows’diets on their reproduction performance.Forty sows were randomly divided into control group and plant extract group(1000 mg/kg).Each pig was a repeat.The experimental period was from 85th day of gestation to parturition.The effects of plant extracts on reproductive performance of sows were studied.The results showed that the birth weight of piglets in the plant extract group was 7.6%higher than that in the control group(P<0.05),the proportion of piglets with high birth weight was significantly increased(P<0.01),and the proportion of piglets with low birth weight was significantly decreased(P<0.05).Compound plant extract could improve piglets’birth weight,piglets’evenness and sows’reproduction performance.
