Evaluation of SPC,DPS SDPP in diets on performance of early-weaned pigs

Sixty-four weanling crossbred pigs(25 d of age) were conducted to evaluate Dried Porcine Solubles(DPS),Soy Protein Concentration(SPC),Spray-Dried Porcine Plasma(SDPP) replacing Fish Meal(FM) in diets.The four treatments were:(A) DPS+FM,(B) SPC+FM,(C) SDPP+FM,(D)FM(control).Pigs were randomly allotted on the basis of initial weight to one of four treatments with eight pigs per pen and two replications per treatment.For the entire 45-d experiment,The ADG of pigs fed the diets containing either DPS,SPC or SDPP were higher than that of control,Pigs in group B,group A,group C increased ADG 13.18 %(P0.05),11.53 %(P0.05),4.43 %(P0.05)compared to control,Pigs in group B,group A increased ADG 8.38 %(P0.05),6.80 %(P0.05)compared to group C,there were no significant difference in ADG between group A and group B(P0.05).Pigs in group B increased ADFI 4.82 %(P0.05) compared to control,but there were no significant difference in ADFI among group A,group C and control(P0.05).There were no significant difference in F/G among all groups.The result showed pigs fed the control diet were lower than that for pigs fed the diets containing either DPS,SPC or SDPP.Pigs that had received SCP,DPS grew faster than those fed with SDPP.
