摘要
选用63头断奶仔猪,分为处理1组(3000mg/kg普通饲料级氧化锌)、处理2组(250mg/kg纳米氧化锌)、处理3组(500mg/kg纳米氧化锌)三个处理,每个处理3个重复,每个重复7头仔猪,试验期20d。结果表明:纳米氧化锌(500mg/kg)能显著提高断奶仔猪的日增重(与处理1组相比,提高9.91%),改善肉料比,有较好的经济效益。
63 Herb of "D × L × Y" weanling pigs were selected and divided into treatment group [ (zinc oxide, 3 000 mg/kg), treatment group Ⅱ (nano-zine ,oxide, 250 mg/kg) and treatment group Ⅲ (nano- zinc oxide , 500 mg/kg) , each group had 7 weanling pigs. The result indicated that naao- zinc oxide(500 mg/kg) could help enhance weanling pig's growth performance , improve the feed utility . gain good economical profit.
