摘要
选用食用菌基质、豆腐渣和麒麟菜渣等废弃农副产品经生物发酵工艺处理的生态饲料(FP组)、晒干并喂前喷洒微生态制剂(AM组)和晒干直接饲喂(CK组)3种处理,进行奶牛饲养试验,结果证明,经生物发酵的生态饲料效果最佳,FP组与CK组相比,产乳量、乳料比、乳脂率和乳蛋白分别增加2.44kg(P=0.04)、0.48(P=0.009)、0.37个百分点(P=0.002)、0.13个百分点(P=0.016),相应提高11%、18%、13%和5%,产乳成本减少0.11元/kg(P=0.015),节省15%。
Ecological feedstuff made by mushroom base dregs, soya-bean residue and eucheuma dregs is handled with three kinds of technique： biological fermentation （ FP group）, sunning dry and spraying microbial preparation before feeding （ AM group）, and sunning dry （ CK group）. These are in progress milk cow feeding experiment, which shows： FP group is best, compared with CK group. The milk yield, ratio of milk yield and feed, milk protein and milk fat increase by 2.44 kg （P = 0.04） 0.48 （ P = 0.009 ） 0.37 percentage point （P =0.002） ,0. 13 percentage point （P =0.016） respectively,and improve 11% ,18% ,13% and 5% correspondently. The product milk cost decrease 0. 11 yuan / kg （P = 0.015 ）, 15 % lower than before.
