摘　　要：本试验旨在研究母猪妊娠后期和哺乳期添加复合油粉对母猪繁殖性能的影响。试验选取22头二元妊娠母猪(3~5胎),根据母猪预产期、胎次、体况相近的原则,随机分为2组即对照组(添加3豆油)和试验组(添加5复合油粉),每组11个重复,每个重复1头母猪。预试期7 d,正式期42 d(自母猪分娩前14 d开始至28 d仔猪断奶时结束)。结果表明,与对照组相比,试验组断奶仔猪数增加1.75头,仔猪初生窝重和平均初生重分别增加3.63 kg和0.27 kg;试验组仔猪的28 d断奶窝重显著提高24.93(P<0.05)。日粮中添加复合油粉能显著提高母猪的泌乳性能(P<0.05),试验组母猪整个哺乳期的泌乳量比对照组提高17.45 L。The purpose of this experiment is to study the effect of adding compound oil powder to sows during late pregnancy and lactation on the reproductive performance of sows.Twenty-two Landrace×Large White crossbred sows(3-5 parity),with similar expected date of birth,parity and body condition,were randomly divided into 2 groups with 11 replicates per group and one sow in each replicate.Two treatments were the control group(adding 3%soybean oil)and trial group(adding 5%compound oil powder).The pre-test period is 7 days,and the test period was 42 days(from the 14th day before sows gave birth to the 28th day when piglets were weaned).The results showed that adding 5%compound oil powder to the sow diet could enhance the number of weaned piglets increased by 1.75,the litter weight and average birth weight of piglets increased by 3.63 kg and 0.27 kg,respectively.The litter weight of piglets weaned at 28 d significantly increased by 24.93%(P<0.05).Meanwhile,adding compound oil powder in the diet could significantly improve the lactation performance of sows(P<0.05),and the lactation yield of sows in experimental group was 17.45 L higher than that in control group during the whole lactation period.
