Effect Of Low Protein Diets Adding Small Peptide On The Performance And Immunity Index In Growing Pigs

The objective of this study was to research the effects of Small Peptide on growth performance and immune status of growing- finishing pigs.experiment:Piglets were at 20kg and allocated to 2 treatments with four replicates of each treatment and eight growing pigs per replicate according to birth date, litter, and gender, using complete random single factorial design. The results showed that: (1)Compared with the control group, treat group had increased the daily weight gain by 20.8%, There was significantly effect observed in daily weight gain (P< 0.01) and dccreased ratio of feed to gain by9.6%, there was significantly effect observed in daily weight gain (P<0.01); (2)Compared with the control group, the content of total protein,IgA,IgG,IgM had increased by 2.5%,8%,5.6％,3.0%, but no significant effect among the two treatments (P>0.05), the content of albumin had increased by 13%, there was significant effect observed (P<0.05)。...
