摘要
有益微生物群（ＥＭ）技术对蛋鸡生产具有促进作用。６周试验表明，以２０％比例将ＥＭ发酵饲料添加于蛋鸡日粮中，日均产蛋量提高５．５４％，产蛋率提高４．７２％，料蛋比下降５．２５％；毛利润提高１９．５９％，边际成本利润率为２４．７５；蛋白哈氏单位提高１０．３１％，蛋黄颜色提高１．５罗氏级，蛋壳厚度增加６．９９％。
It is effective that Effective Microorganism(EM)technology improves layer productive property and egg quality In 6 weeks test with 20% EM fermented feed added to daily ration of layer,the average egg production per day increased by 5.54%,the rate of producing egg increased by 4.72%,the ratio of feed to egg decreased by 5.25%.the gross benefit inereased by 19.59%,and the marginal benefit-cost ratio was 24.75;Haugh unit of the albumen increased by 10.31%,the yolk color heigbtened by 1.5 Roche scales and the eggshell thinkness increased by 6.99%.
