| 摘 要： | 试验旨在研究哺乳母猪日粮中添加不同脂肪源对母猪繁殖性能和饲粮养分消化率的影响。选取第3胎次PIC母猪30头,随机分配到3个处理,即对照组、2%大豆油组和2%脂肪粉组,每个处理10个重复。试验从母猪分娩开始,到仔猪21日龄断奶时结束。结果表明:与对照组相比,脂肪粉组第3周平均日增重(ADG)和第3周窝增重分别提高了26.29%(P<0.05)和23.93%(P>0.05),大豆油组分别提高了19.72%(P>0.05)和17.85%(P>0.05)。且脂肪粉组的提高幅度最大。由此可知,饲粮中添加不同脂肪源可提高饲粮养分消化率,改善哺乳仔猪的生产性能,且脂肪粉优于大豆油。

| Abstract: | This study was conducted to investigate the effects of different fatty sources on performance and nutrient digestibility of lactating sows.A total of 30 PIC sows(similar expected date of delivery,parity and body condition) were randomly allocated into 3 treatments with 10 replicates per treatment and one sow per replicate.The 3 treatments contained control group and 2% soybean oil group and 2% fat powder group.The experiment lasted from postfarrowing to day 21 of lactation(weanling).Compared with the contro... |
