摘要: 选用24~26日龄"长×大"二元杂交断奶仔猪96头(平均体重6.84 kg±0.16 kg),研究不同形式氧化锌对断奶仔猪生长性能和腹泻的影响。试验仔猪按完全随机区组设计分为4组,每组3个重复,每个重复8头仔猪。对照组饲喂基础日粮,试验1、2、3组分别在基础日粮中添加2800 g/t普通氧化锌、800 g/t包膜氧化锌、500 g/t纳米氧化锌,试验期14 d。结果表明,与对照组相比,试验1、2、3组断奶仔猪平均日增重分别提高了15.26%(P<0.05)、9.88%(P<0.05)和14.69%(P<0.05),料重比降低了9.59%(P<0.05)、7.53%(P<0.05)和10.27%(P<0.05);腹泻率降低了66.67%(P<0.05)、55.55%(P<0.05)和55.55%(P<0.05)。试验1、2、3组之间断奶仔猪的平均日增重、料重比及腹泻率均无显著差异(P>0.05),说明包膜氧化锌和纳米氧化锌是一种代替高剂量普通氧化锌的可行选择。

Abstract: 96 24 to 26 day old "L譟" weaned piglets (average bodyweight with 6.84 kg?0.16 kg) were used to study the effect of different form zinc oxide on the growth performance and diarrhea for 14 days feeding trial. The piglets were randomly allocated for four groups consisting of 3 replicates of 8 piglets each. The control group was fed the basal diet, the groups 1, 2, 3 were fed the basal diet adding 2800 g/t zinc oxide, 800 g/t fat-coated zinc oxide, 500 g/t nanometer zinc oxide respectively. The results showed that the average daily gain raised 15.26% (P<0.05), 9.88% (P<0.05) and 14.69 (P<0.05),the ratio of feed to gain reduced 9.59% (P<0.05), 7.53% (P<0.05) and 10.27% (P<0.05), the diarrhea ratio reduced 66.67% (P<0.05), 55.55% (P<0.05) and 55.55% (P<0.05) respectively compared with the control group, but the groups 1, 2, 3 were no significant differences in average daily gain, ratio of feed to gain and diarrhea ratio (P>0.05) among the zinc oxide, fat-coated zinc oxide and nanometer zinc oxide. It implied that the fat-coated and nanometer zinc oxide were a practicable alternative to high dosage zinc oxide.

Key words: zinc oxide; fat-coated zinc oxide; nanometer zinc oxide; diarrhea ratio; growth performance
