摘要
选择１０日龄ＡｒｂｏｒＡｃｒｅｓ雏鸡３００只，随机分成６组，每组５０只。第一组饲以含锌３０μｇ．ｇ的玉米——豆饼型基础日粮，其它五组日粮依次含锌６０μｇ．ｇ，１１０μｇ．ｇ，１６０μｇ．ｇ，２１０μｇ．ｇ，２６０μｇ．ｇ。５０日龄时，分别进行心脏采血，测血清中淀粉酶、乳酸脱氢酶（ＬＤＨ），谷丙转氨酶（ＧＰＴ），碱性磷酸酶（ＡＫＰ）的活性及血清含锌量。结果表明，在试验条件下，１，６组血清淀粉酶的活性与２，３组差异不显著，但明显低于４，５组。血清中ＬＤＨ和ＡＫＰ活性随饲料锌水平的提高而提高，ＧＰＴ活性随饲料锌水平的提高基本不变，血清中锌含量随料锌水平的提高而提高。
Ten-day-old Arbor broiler Acres were divided into six groups at random.There are fifty chicks per group.The first group were fed on the feed with 30pp zinc.The other five groups' feed zinc level are 60μg.g,110μg.g,160μg.g,210μg.g and 260μg.g.The experiment,showed that when the dietary zinc level was between 60 to 210μg.g,the viability of serum amylaze was increased with the dietary zinc increasing,when the dietary zinc level was increased,the viability of LDH and AKP were also increased,while the viability of GPT changed little.
