摘　　要：为了研究陈旧鸡粪转化饲料的能力,试验采用新鲜鸡粪约1 000 kg,随机分为2组,每组500 kg,分别堆放在露天处(E组)和避雨处(C组),每7 d检测其钙、磷含量变化情况。结果表明:随着堆放时间的增加,鸡粪中钙、磷含量均呈升高趋势,钙磷比无显著变化(P>0.05)。说明陈旧鸡粪的钙磷含量较新鲜鸡粪高,鸡粪的钙、磷比值较大,因此加工转化饲料时最好补充一定量的磷。To study the conversion ability of old chicken manure for feed,1 000 kg of fresh chicken manure was used and randomly divided into2 groups of 500 kg each,including group E and group C. The two groups of chicken manure were stacked in the open air for group E and the shelter from the rain for group C,respectively. The variation in the contents of calcium and phosphorus in chicken manure was detected at every7 d. The results showed that the contents of calcium and phosphorus in chicken manure showed an increasing trend with the increase of stacking time,but there was no significant change（ P 0. 05） in the calcium- phosphorus ratio between the two groups. The results indicate that the contents of calcium and phosphorus in old chicken manure were higher than those in the fresh chicken manure,and the calcium- phosphorus ratio is larger in chicken manure. Thus,it is best to add a certain amount of phosphorus when processing and converting chicken manure into feed.
