籽粒苋饲喂肉鸡的营养评价及试验研究

An Investigation on Amaranthus as Broiler's Feed

该试验制取了籽粒苋（美国红苋）籽粉和颖壳、茎、叶按１∶１∶１的混合粉，用２×３设计方法配合加入肉仔鸡饲粮中，籽粉水平为０％，５％，１０％，混合粉水平为０％，２％，４％，对肉仔鸡生产性能未产生明显的正负效应．籽粒克籽粉的营养价值丰富，含粗蛋白１４．４％，粗脂肪７．８％，代谢能为１３．７ＭＪ／ｋｇ。箱前采收籽粒后的植株地上部分别制取的混合粉仍含粗蛋白质９．２％和丰富的钙源，但粗纤维含量达２９％，代谢能５．２７ＭＪ／ｋｇ，故适用于低能量饲粮中使用。

A 2×3 factorial experiment was conducted with 450 broilers to determine the nutritive value of red American Amaranthus mill of seeds and mill of husk, leaves and stems mixed at 1: 1:1 added in broilerl's feed. There was no apperant effect on the performance of broiler when seed mill was 0%, 5%, 10% and the mixed mill was 0%, 2%, 4%. The seed mill contained CP 14.4%, EE 7.8 and ME 13.7MJ/Kg.The mixed mill made after havesting the seeds before frost contained CP 9.2%, CF 29.0%, Ca 3.5% and ME 1.26MJ/Kg and was adaped to feeds with lower energy.
