饲喂杂交狼尾草对乐平猪(东乡花猪)繁殖性能的影响

为研究杂交狼尾草对乐平猪繁殖性能的影响,根据母猪体况、妊娠时间、胎次一致的原则,选取30头东乡花猪经产母猪。按饲喂新鲜杂交狼尾草的量不同,试验设3个处理,每组10头,按妊娠前期(30 d前)、中期(30～90 d)和后期(90 d后)3个阶段,分别饲喂0、2.0和3.0 kg/d杂交狼尾草(即对照组、替代15%精料组、替代25%精料组),基础日龄相同,进行了一个繁殖周期的试验,结果表明:以60日龄窝重比较,2个试验组比对照组分别提高11.07%和12.55%,达到显著差异(P<0.05);每头母猪年增收分别达398.55元和487.70元;另外,饲喂狼尾草提高了生态效益,净化了环境。

Effects of Feeding Hybrid Pennisetum on Reproductive Performance of Leping Pig (Dongxiang Flowery Pig)

In order to study the effects of feeding hybrid Pennisetum on the reproductive performance of Leping pig(Dongxiang flowery pig),30 heads of Dongxiang flowery sows were selected and used for the test based on the principle of the same body condition,gestation time and production time.According to the amount of feeding fresh hybrid Pennisetum,the test was conducted with 3 treatments,10 heads in each treatment.At earlier pregnancy stage(before 30 d),medium pregnancy stage(30～90 d) and latter pregnancy stage(90 d),the tested sows were fed by 0 kg(CK),2.0 kg(treatment 1) and 3.0 kg(treatment 2) fresh hybrid Pennisetum per day respectively,the sows in different treatments had the same basic day-age,the whole reproduction period was tested.The results showed that the litter weight of 60-day-old piglets in treatment 1 and treatment 2 was 11.07% and 12.55% higher respectively than that in CK,and there was significant difference between them(P<0.05).In comparison with CK,treatment 1 and treatment 2 increased the income per sow per year by 398.55 yuan and 487.70 yuan respectively.Meanwhile,feeding hybrid Pennisetum enhanced the ecological benefit,and purified the environment.
