不同教槽料对仔猪生长性能的影响

Effect of different creep feed on the growth performance of piglets

试验采用新农猪场杜洛克公猪与PIC母猪杂交所产配套系商品仔猪,试验分为3组,每组3窝(30~33头仔猪,n≥30),分别饲喂3种不同的教槽料。结果表明:粉料开口王的诱食效果好于半粉料的乐口酥,颗粒料教槽王的诱食效果最差。从日增重来看,乐口酥和开口王的饲喂效果明显好于教槽王,尽管乐口酥的采食量没有开口王大,但是日增重却超过了开口王。断奶后,饲喂乐口酥的仔猪料肉比最低;采食量最好的开口王反而料肉比最高。7~14 d,饲喂3种教槽料的仔猪腹泻率差异不显著(P>0.05);14~28 d,饲喂开口王的腹泻率极显著高于教槽王与乐口酥(P<0.01)。饲喂乐口酥的仔猪皮毛光滑程度高于教槽王和开口王。3种教槽料基本上都能保持仔猪肤色红润,皮毛光滑,除个别腹泻仔猪影响毛色外,无显著差异。各组仔猪在全程生长过程中,死亡率无显著差异(P>0.05),个别仔猪的死亡是由于先天性发育不良,体弱,不吃、拉稀不止、脱水所导致的。

In Xinnong pig farm Duroc PIC sows created hybrid pigs, were boars and selected to explore the effects of different creep feed on pro- ductive performance of piglets. Piglets were ran- domly divided into 3 groups, each group had 3 nests（30-33 piglets, n≥30）, fed with three kinds of creep feed, respectively. The result showed that at- tractant effct of KKW power was better than that of I, KS crisp, a half of powder; the worst attractant effect was that of JCW, the particulate material creep. From the average daily gain, the feeding effects of I^KS crisp and KKW were significantly better than that of JCW, feed intake of LKS crisp was not more than KKW, but its daily weight gain was indeed better than KKW. After weaning, the lowest ra- tio of meat to feed was that of piglets fed LKS crisp, the highest ratio was that of piglets fed KKW. 7~ 14 d, there was no obvious diferenee in diarrhea rates of piglets（P〉0.05）; 14~28 d, piglets fed KKW were significantly higher than others（P〈0.01）. Feeding LKS crisp, piglets had the best fur.And feeding three kinds of creep feed, piglets had ruddy complexion, smooth fur, basically, except those caused by diarrhea, they had no large difference. In whole growth process, there was no significant difference in mortalily（P〉0.05）, individual death of piglets were due to congenital dysplasia, frailty, starvation, diar- rhea. dehydration.
