【摘要】 选取1日龄同批孵化、体重相近、健康芦花鸡540只(公母各半),随机分3组,每组3个重复,每重复60只鸡,分别饲喂高、中和低3种不同营养水平饲粮。试验结果表明:中等营养水平的饲粮能较好的满足芦花鸡的生长需要。高营养水平饲粮只对芦花鸡1～28 d有明显地促生长作用,28 d以后作用较小。低营养水平的饲粮则不能满足芦花鸡正常的生长需要。中等营养水平饲粮组的活重、屠宰率、半净膛率、全净膛率明显大于低营养水平饲粮组,略大于高营养水平饲粮组。高营养水平饲粮组的腿肌率和胸肌率大于中等营养水平饲粮组和低营养水平饲粮组,中等营养水平饲粮组的皮脂厚、肌间脂宽要比高营养水平饲粮组和低营养水平饲粮组大,但差异均不显著。更多还原

【Abstract】 540 healthy Luhua chickens(1-day old)with similar body weight were randomly separated into 3 groups,3 replicates per group,60 birds per replicate.Group Ⅰ,GroupⅡ,GroupⅢ were fed high dietary nutrition,medium dietary nutrition and low dietary nutrition separately.The results showed that:(1) Growth performance: the medium dietary nutrition can meet the need of Luhua chicken’s growth.The high dietary nutrition had obviously growth promoting effect for only 1～28 d.The low dietary can not meet the growth need of Luhua chicken.(2) Slaughter performance: the live weight,slaughter rate,half-eviscerated rate,and carcass net rate were significantly greater than the low dietary group,slightly higher than the high dietary group.The chest and leg muscle percentage of high dietary group was higher than the other two groups.The abdominal fat rate and thick leather fat of medium group was the highest,but there were no significant differences.In short,recommend fed Luhua with the medium dietary nutritions.更多还原
