日粮中添加青绿饲料对土种鸡生产性能的影响

The Effects of Adding Green Forage in Diet on the Production Performanc of Local Chicken

研究了土种鸡日粮中添加青绿饲料对其生产性能的影响。试验应用 30日龄土种鸡 12 0 0 0只 ,随机地分成6组 ,每组 2 0 0 0只。青绿饲料为田间收割获得 ,主要成分为紫云英、野豌豆和苜蓿等。通过切碎按 0 % ,5 % ,10 % ,15 % ,2 0 %和 2 5 %添加量替代基础日粮直接饲喂 ,试验期为 5 0d。结果表明在 80日龄上市时试验组土种鸡随着青绿饲料添加量的增加只平均体重略低 ,但与完全饲喂精料的对照组土种鸡比较 ,差异不显著。 10 %和 15 %添加量组最佳 ,平均较对照组鸡省料 2 2 5 .3g/只 ,降低饲料成本显著 ,经济效益大。本试验结果表明 30～ 80日龄土种鸡日粮中添加青绿饲料是可行的 ,尤其是 10 %～ 15

The effects of the diet with green forage on the production performance of local chicken were studied. 12 000 30-day local chickens were divided into six groups in random, each group 2 000 chickens. The chicken fed on the diets containing astragalus sinicus, wild pea and alfalfa in the proportion of 0%, 5%, 10%, 20% and 25% replacing basal diets for 50 days. The results showed that the average gain of the local 80-days chickens to be marketed was reduced with the proportion increasing of green forage, but there was no significant difference comparing with the group entirely fed on compound feed. The average diet requirement of the group fed on the diet containing the forage in the optimum proportion of 10% and 15% were decreased by 225.3 g , therefore the feed cost was reduced significantly resulting in a good economic benifit. The test result showed that it was feasible for local 30～80-day chickens to be fed on the diets containing the forage, especially with an addition of 10% and 15%.
