湿拌饲料对仔猪开食及生产性能的影响

Effect of Liquid Diets on Starter and Growth Performance of Piglets

本试验选经产大白×DVI系二元仔猪20窝,每窝在9头以上,分为两组,每组10窝,分别以干颗粒料与拌湿的颗粒料作为仔猪的开食料,通过饲养试验,研究湿拌饲料对仔猪开食及生产性能的影响。试验结果表明,饲喂湿拌饲料的仔猪,在14日龄全部开食;仔猪腹泻率,在7～21日龄,试验组比对照组高8.7%,而在21～35日龄与35～42日龄,试验组比对照组低9.4%与5.3%;仔猪个体重,21日龄时,试验组比对照组高1.1%(P>0.05);到35日龄与42日龄时,试验组比对照组分别高10.6%与7.9%(p<0.05);仔猪日增重,7～21日龄时,试验组比对照组高1.0%(P>0.05),而21～35日龄时,试验组比对照组低6.5%(P>0.05),在35～42日龄,试验组比对照组高1.8%(P>0.05)。

In this experiment,20groups crossed piglets(Duroc×DVI ,more than9pigs /group)were devided into control group(dry diets)and trial group(liquid diets).The results showed that compared to the control group,the pigtets of liquid diets group started to eat in14day-old,The number of dionhoea infection increased8.7%during7～21day-old,but decreased9.4%and5.3%during21～35day-old and35～42day-old respectively;The weight of piglets increased1.1%(P>0.05)and7.9%(P<0.05)during7～21、21～35and35～42day-old;Average daily gain of piglets increased1.0%(P>0.05),but decreased6.5%(P>0.05)and1.8%(P>0.05)during21～35and35～42day-old.
