摘要:本研究旨在对微量元素螯合物对肉鸡的促生长效果进行探讨。试验将20日龄鸡进行分组,分为4个试验组,在饮水中连续添加不同浓度微量元素螯合物,对照组(0 g/ L),高剂量组(25 g/500 L),中剂量组(12.5 g/500 L),低剂量组(6.5 g/500 L),饲养至40日龄。研究连续添加微量元素螯合物对肉鸡的促生长作用和对肉鸡器官发育的影响。结果表明:在饮水中连续添加微量元素螯合物对肉鸡有显著的促生长作用(P<0.05);能有效降低料肉比;对低剂量组肾脏器官指数有显著的影响(P<0.05),和对照组相比差异显著。29825 毕业论文关键词:微量元素螯合物;促生长作用;器官指数
Effects Of Chelated Trace Element On Growth Performance Of Broilers
Abstract:The experiments were designed to investigate the effects of chelated trace element on growth performance and purtenance index of broilers.200 20-day old broilers were pided into four groups randomly ,and were fed with different levels chelated trace element in drinking water(0 g/500 L,50 g/500 L,25 g/500 L,12.5 g/500 L) separately .The result showed: there is significant effect on growth performance(P<0.05),and it also can effectively reduce the Feed Conversion Ratio ;the (12.5 g/500 L) group’s kidney purtenance index has significant difference with the( 0 g/500 L) group(P<0.05).
Key words: chelated trace element;growth performance;purtenance index
