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.
