摘要
选用35周龄产蛋高峰期蛋鸡480只,随机分成2个处理,每个处理4个重复,每个重复60只鸡。以玉米—豆粕—杂粕型基础日粮为对照组,在此营养水平基础上添加0.05%的瑞特利禽专用饲用复合酶为试验组。结果表明:试验组产蛋率、蛋壳厚度分别比对照组提高1.65%和2.38%,并降低破蛋率0.248%,但差异不显著(p>0.05);饲料转化率提高2.41%,差异显著(p<0.05)。
The choose 480 layers at 35 weekly ages, random dividing 2 treatments, the per treatment dividing 4 repeats, there are 60 layer the per repeat. The control that corn、soybean mael and cotton seed meal based diets for layeys, the test that based diets for layers of control and addition of 0.05% Reteli Feed Enzyme for poultry. Result:improve layer significantly both growth laying rate 1.65% and thickness of eggs 2.38%, reduce rate of breakage of eggs 0.248%, but differ from is not remarkable (p>0.05); improve feed conversion rate 2.41%, differ from is remarkable (p<0.05).
