Response of early weaned pigs to full-fat soyabean diets supplemented with different animal protein sources

Abstract

24 Large White X Landrace pigs weaned at 28 days with initial liveweight of 5.27 ±0.23 kg were fed four animal protein concentrates (fish meal (FM), Chicken offal meal (COM), fresh blood meal (FBM) and parboiled blood meal (PBM) in diets based on full-fat soyabean (FFSB) for 8 weeks to test different animal protein sources for early weaned pig. The diets contained 23% crude protein and 3100 Kcal ME/kg diet. Blood meal slightly  reduced weight gain and feed intake but compared favourably with fish meal and chicken offal meal in efficiency of feed utilization. Parboiling of the blood slightly (P > 0.05) depressed the performance of the pigs even when the pigs had the same feed intake. Fish meal increased (P < 0.05) serum total protein and serum albumin levels. This study indicated that early weaned pigs fed soyabean based diets supplemented with chicken offal
meal and blood meal gave similar performance to those fed diet supplemented with fish meal.
