摘要
为探讨高锌对断奶仔猪生长性能的影响，将４窝日龄、体重相近的断奶仟猪按对等原则均分三组。第一、第二组日粮中分别添加ＺｎＯ ０．２５％，ＺｎＳＯ_４·７Ｈ_２Ｏ ０．８８％（均含Ｚｎ２０００ｐｐｍ），结果３５天后测得两试验组比对照组育成率提高１１．１１％（Ｐ＞０．０５）：发病率分别降低了２２．２２％（Ｐ＞０．０５）和４４．４４％（Ｐ＜０．０５）；增重速度分别提高了１９．３１％（Ｐ＞０．０５和４０％（Ｐ＜０．０１）；饲料利用率分别提高了１０．２８％和２３．８３％。
In order to investigate the effects of high-content zinc on the growth weaner, we have made an experiment as follows: First, weaners at four litters are equally separated into three sections. Then the addictives (ZnO 0. 25%; ZnSO_4 7H_20 0.88%; each containing zinc 2000ppm) are put into the every-day food stuff for two sections labeled by No.1 and No.2. The result will he tested in 35 days, that survival rate in the two sections has improved by 11.11%(P>0.05); While the mobidity reduced by 22.22%(P>0.05) and 44.44%(P>0.05) respectively, the weight growth rate increased by 19. 13% (P >0. 05) for one section and 40% (P< 0. 01) for the other. and the feed utilization ratio by 10.28% and 23.83% for each.
