日粮添加高铜对幼龄水貂生长的影响
Effect of High Copper Level Diets on Growth of Young Minks
摘要
Abstract
This test was conducted to study the effects of different copper levels and high copper level diets on growth of young minks.Seventy healthy minks at the age of 80-day were randomly divided into 7 groups with 10 minks in each group.The minks in control group were fed with experimental diet with copper level of 5.98 mg/kg;Copper was supplemented into six treatment group diets with levels of 210 mg/kg,220 mg/kg,240 mg/kg,250 mg/kg,260 mg/kg and 310 mg/kg,respectively.The experiment lasted for 60 days.According to the examination and analysis of the minks' growth,the results showed that:the growth of minks in group 1,group 2,group 3 and group 4 were higher than those in control group;the growth of minks in group 4 was the highest,the growth of minks in group 5 and group 6 reduced.In conclusion,when the diet was supplemented with 250 mg/kg copper and the copper level of diet arrived at 255.98 mg/kg,the growth of young minks was optimal,excess copper in diet would inhibit the growth of minks.关键词
