摘要
EM制剂能促进蛋鸡的生长,提高生产性能,提高经济效益。40d试验表明,饲喂含有EM原液发酵饲料的鸡群与对照组鸡群比较,产蛋量提高2.74%,产蛋数提高2.73%,产蛋率增加2.73%,料蛋比下降2.69%,毛利润提高4.6%,每公斤鸡蛋增收毛利0.09元,每只鸡增收毛利0.17元。
The results of experiments shows that effective microorganism(EM) preparation improves layer productive property and economic benefit. In 40 days test with EM fermented feed added to daily ration of layer, the average egg production per day increased by 2.74%, the rate of producing egg increased by 2.73%, the ratio of feed decreased by 2.69%, the gross benefit increased by 4.6%.
