高蛋白料精、光合菌液和鱼粉对肉鸡生长性能的影响

Effect of high-protein concentrate,photosynthetic bacteria culturation and fish meal on the growing performance of broilers

采用在基础日粮中分别加高蛋白料精＋光合菌液（Ｉ组），高蛋白料精（Ⅱ组），光合菌液（Ⅲ组），鱼粉（Ⅳ组）四种方法饲喂，对肉鸡的生长性能进行比较试验。试验结果：Ⅰ组生长速度最佳，平均增重比Ⅱ组、Ⅲ组、Ⅳ组分别揭高４．３９％、１６．７９％和２％，Ⅳ组和Ⅱ组次之，Ⅲ组较差。结果表明：用高蛋白料精或高蛋白料精加光合菌液替代进口鱼粉饲喂肉鸡是可行的，能降低饲养成本，达到提高经济效益的目的。

A com parative experiment was cond ucted in present paper.The broilers were usedand high-protein concentrate+photosynthetic bacteria cuituratfon(group 1),high-protein con-centrate(group 2 ) photosynthetic bacteria culturation(group 3)and fish meal(group 4)wereseparately added in a basal diet.Group 1 showed the best grow rat ,its daily gain increased by4.39%,16.79%and 2%as compared with group 2, 3 and 4.group 4 was secend only to group1 while group 3 gave the lowest grow rate. The result show the imported fish meal may be re-placed by high-protein con centrate and high-protein concectrate+photosynthetic bacteria cul-turation,which can reduce the feeding cost and increase the economic benefit.
