Eighteen crossbreed piglets Duroc ×Landrace ×Yorkshire (14-day old) were randomly divided into three groups with six piglets each group. Control was fed with 8% animal plasma (AP). Trial 1 was fed with 4.9% AP and 4.9% SAP. Trial 2 was fed with 12.62% SAP. This raising period was 30 days and divided into three periods with earlier period (0-15 days), latter period (16-30 days) and whole period (0-30 days). The results showed that average daily gains (ADG) in trial 1 were increased 16.33%, 12.64% and 13.94% (P >0.05) and Efficiency of feed conversions (EFC) improved 17.35%, 11.40% and 13.46% than control in respective periods; ADG in trial 2 were reduced 12.24%, increased 4.21% and reduced 0.40% (P>0.05) and EFC were improved 19.81%, 13.08% and 15.76% than control in respective periods. Means of TG and LDL-C/ HDL-C in trial 1 were lowest in three groups and reduced 6.54% (P >0.05) and 0.96% than control. Means of TG, TC, LDL-C, HDL-C, LDL-C/ HDL-C were the highest in trial 2 among three groups and increased 8.93% (P >0.05), 39.69% (P <0.05), 34.94% (P >0.05), 27.31% (P >0.05) and 5.96% than control respectively. It was concluded that substituting part Ap for SAP in 14-day old piglets Feed was practicable.展开更多
