摘要
通过在三黄雏鸡日粮中添加高硒、高硒钴、高硒钴锌以及高硒钴锌铁4种紫花苜蓿草粉的试验,研究其对雏鸡生长和代谢的影响。结果表明在鸡饲料中添加5%~15%的4种高微牧草均可提高饲料报酬,提高雏鸡对饲料的利用和转化。其中,在鸡饲料中添加10%的高硒钴锌的苜蓿草粉,应用效果最好,添加后雏鸡的体重增加了150%,比对照提高了93.5%,料肉比比对照下降了54.0%。
The experiment was conducted to study the effect of adding 4 kinds of alfalfa powder with high selenium,selenium-cobalt,seleniwm-cobalt-zinc,selenium-cobalt-zinc-iron content to the daily diet of broilers on the growth and metabolism was conducted in the Yellow River beach of Henan province.The results showed that 4 kinds of alfalfa powder as an addative feed can raise feed conversion efficiency.Of all alfalfa powder,the one with high selenium-cobalt-zinc content the best effects on the growth and metabolism of broiler.When addative content of above-mentioned alfalfa hay powder was 10% of ration,the body weight can be increased by 150%(raising by 93.5% compared with the control),and forage meat ratio was 10.95(decreasing by 54.0% compared with the control).
