摘要 银杏叶添加剂对黄羽肉鸡生产性能影响的结果表明:银杏叶添加剂早期对肉鸡日增质量的影响小,但15日龄后有一定的促进作用;可提高21日龄、35日龄肉鸡的耗料增重比;1%、2%、5%的银杏叶添加剂可分别提高35日龄肉仔鸡成活率0.6、1.9、1.6个百分点。此外,银杏叶添加剂还可减轻鸡粪臭味,2%的银杏叶添加剂可使粪便的NH3、H2S含量分别降低26.7%、30.9%。 The effect of gingkgo leaf additive on the production performance of yellow-feathered broilers was studied.The results showed that gingkgo leaf additive had little influence on the daily weight gain of broilers in the earlier phase,but it promoted the daily weight gain of broilers whose age was over 15 days,and it could enhance the forage/weight ratio of 21-day-old and 35-day-old broilers.The gingkgo leaf additive at the dosage of 1%,2% and 5% could increase the survival rate of 35-day-old broilers by 0.6%,1.6% and 1.9% respectively.In addition,the application of gingkgo leaf additive also could lighten the funk of chicken manure,and 2% gingkgo leaf additive could decrease the contents of NH3 and H2S in chicken manure by 26.7% and 30.9% respectively.
