| 摘 要： | 试验以20头妊娠90d的初产母猪(长白×大白)为试验动物,研究日粮中使用5%Nutri-Pal对其繁殖性能的影响。试验分对照组及5%Nutri-Pal试验组。结果表明:与对照组相比,试验组母猪的采食量略有提高(P>0.05),窝产活仔数增加0.55头、初生窝重增加1.57kg、断奶后7d内发情率提高了22.3%,弱仔、死胎、木乃伊的比例均有不同程度的下降,但母猪窝总产仔数、断奶到发情的间隔无显著差异(P>0.05)。仔猪15日龄窝重、断奶窝重比对照组分别提高了3.53kg和5.56kg,死亡率下降了37.57%。结果显示,日粮中使用5%Nutri-Pal能促进夏季初产母猪的繁殖性能。

| Abstract: | A total of twenty crossbred primiparous sows(Landrace×Yolk)were utilized in this study to evaluate the effects of NUTRI-PAL supplementation in diet of sows through late gestation and lactation on reproductive performance of sows and growth performance of sulking piglets during the summer season. There were two dietary treatments control and experimental diet containing 5% Nutri-Pal. The results indicated that there was a minor increased feed intake for sows due to supplementation of Nutri-Pal in diet. The primiparous sows fed the diet containing 5% Nutri-Pal had 0.55 piglets born alive per litter, 1.57 kg in litter birth weight more than that of control, whereas a corresponding reduction occurred in rate of weak, dead and mummy at birth. Compared with control, under the similar starter consumption, piglets litter weight at d 15 and litter weanling weight at 23 d of age increased 3.53 and 5.56 kg, mortality of piglets was reduced 37.57% . Collectively, results from this study indicated 5% Nutri-Pal supplementation in diet of sows had beneficial effects in improving the reproductive performance of primiparous sows during the summer season. |
