摘要
为探明杜仲提取物在肉鸡日粮中的适宜添加量,选用1日龄健康三黄鸡150只,随机分为5组,每组3个重复,分别饲喂5种不同日粮,第5组为空白对照组,第1,2,3,4组为试验组,在基础日粮中分别添加1 500,2 000,2 500 gA的杜仲提取物或50 mg/kg的黄霉素(效价为8%).试验分两个阶段饲养(0～4周龄和5～10周龄).试鸡自由采食和饮水.结果表明,日粮中添加杜仲提取物能显著提高三黄鸡平均日增重,提高饲料转化率,改善三黄鸡胴体品质,且能明显提高胸肌率.建议在肉鸡日粮中添加2 000～2 500g/t的杜仲提取物.
To study the effect of Eucommia ulmoides extract on the growth performance and carcass qualities, and the approaches to its optimal supplement in broiler diets, 150 one-day-old broilers wore randomly assigned to five treatments with throe duplicates. There wore 10 broilers per duplicate. Feed and water wore provided ad libitum. The whole experiment was divided into two phases （0-4 wk and 5- 10 wk） .The 5 groups fed on the same basic diet, but with 4 of them supplemented with 1 500, 2 000, 2 500 g/t Eucommia ulmoides extract or 50 mg/kg Flavomycin. The results showed that Eucommia ulmoides extract increased ADG, improved FCR and the carcass qualities. It indicates that the optimal level of Eucommia ulmoides extract in the diet of broilers is 2 000-2 500 g/t.
