摘要：

选用28日龄断奶的三元杂交(北京黑猪×长白×杜洛克)仔猪144头,以检测血浆蛋白粉(SDPP)和乳清粉(DW)对仔猪生产性能和血清 GOT,GPT,AKP 活性及 BUN 含量的影响。试验分6个处理即:0SDPP+0DW,0SDPP+5%DW,0SDPP+10%DW,5%SDPP+0DW,5%SDPP+5%DW 和5%SDPP+10%DW。结果表明:处理6的 ADG 最大(P<0.05),饲料转化效率(F/G)最好(P<0.05),GOT,GPT,AKP 酶活性最低。无 SDPP 和 DW 处理的各项指标最差。采食含有 SDPP 日粮的仔猪,其 ADG(P<0.05)、ADFI(P<0.05)明显改进,BUN 含量下降(P<0.05)而氮沉积增加,GOT,GPT,AKP 活性略降低(P>0.05)。随着日粮中 DW 含量从0到10%的递增,仔猪 ADG 线性增加(P<0.022),饲料转化率(F/G)随之改善(P<0.05),但血清 GOT,GPT,AKP 活性及 BUN 含量变化不大(P>0.05)。
