摘要

本试验旨在研究重组猪表皮生长因子(porcine epidermal growth factor,pEGF)对早期断奶仔猪生长性能的影响.选用21日龄断奶三元杂交(杜×长×大)健康仔猪160头,按体重相近、性别比例相同原则随机分成4组,即高档教槽料+500 μg/kg pEGF组(GE组)、高档教槽料对照组(GD组)、中档教槽料+500 μg/kg pEGF组(ZE组)、中档教槽料对照组(ZD组),每组4个重复,每个重复10头仔猪.试验期为10 d.结果表明:1)GE组平均日增重显著高于GD组(P<0.05),比GD组提高了6.29%;ZE组平均日增重极显著高于ZD组(P<0.01),比ZD组提高了17.08%;2)GE组平均日采食量与GD组无显著差异(P>0.05),ZE组平均日采食量显著高于ZD组(P<0.05),比ZD组提高了4.91%;3)GE组料重比显著低于GD组(P<0.05),比GD组降低了4.31%;ZE组料重比显著低于ZD组(P<0.05),比ZD组降低了10.37%;4)GE组腹泻率比GD组降低了57.14%;ZE组腹泻率比ZD组降低了38.46%.由此可见,饲粮添加pEGF提高了饲料转化率,降低了料重比和腹泻率,从而显著改善断奶仔猪生长性能,降低增重成本.

Abstract

This experiment was conducted to investigate the effects of recombinant porcine epidermal growth factor (pEGF) on growth performance of early-weaner piglets. One hundred and sixty healthy weaner piglets (Large×White×Landrace) at 21 days of age were randomly allocated to 4 groups (4 replicates per group and 10 piglets per replicate): high grade creep feed+500 μg/kg pEGF (GE) group, high grade creep feed control (GD) group, median grade creep feed+500 μg/kg pEGF (ZE) group, median grade creep feed control (ZD) group. The trial lasted for 10 days. The results showed as follows: 1) compared with GD group, average daily gain (ADG) in GE group was significantly increased by 6.29% (P<0.05); compared with ZD group, ADG in ZE group was significantly increased by 17.08% (P<0.01). 2) Average daily feed intake (ADFI) was no significant difference between groups GE and GD (P>0.05); compared with ZD group, ADFI in ZE group was significantly increased by 4.91% (P<0.05). 3) Compared with GD group, feed/gain (F/G) in GE group was significantly reduced by 4.31% (P<0.05); compared with ZD group, F/G in ZE group was significantly reduced by 10.37% (P<0.05). 4) Compared with GD group, diarrhea rate in GE group was reduced by 57.14%; compared with ZD group, diarrhea rate in ZE group was reduced by 38.46%. It is concluded that adding pEGF in the diets can improve feed conversion ratio, and reduce F/G and diarrhea rate, which improving growth performance and reducing weight gain cost.
