EFFECT OF DIETARY SUPPLEMENTATION OF ANIMAL BLOOD PLASMA POWDER ON PRODUCTION PERFORMANCE, DRESSED WEIGHT AND IMMUNE RESPONSE OF BROILER

Abstract

Enhancing economical poultry production using low-cost animal blood plasma powder incorporated in poultry rations is a good step toward sustainable poultry production. The purpose of the present study was to evaluate the effect of dietary supplementation of animal blood plasma powder on production performance, dressed weight, and immune response of broilers. Bovine plasma was separated from the whole blood through centrifugation. A total of 240 day-old broiler chicks having uniform body weights were randomly assigned into 4 treatment groups (AP0, AP1, AP2, and AP3). Each group had three replicates of 20 chicks (n=3; 20 birds/replicate). Ross broiler management guidelines were followed for feeding, watering, and vaccination. broiler starter ration (23.2% CP and 2990kcalME/kg) was provided during the brooding stage and switched to the grower diet (20.08% CP and 3112 kcal/kg ME) up to 28 days and finisher (18.86% CP and 3208 kcal/kg ME). Animal blood plasma powder supplemented into the diet at different levels AP1 (0.5g/kg), AP2 (1g g/kg), AP3 (1.5g g/kg), and AP0 (Control 0g/kg) for different groups. The treatment was continued for seven weeks. Significantly lower (P<0.05) feed intake (2809.3g±5.36) and high body weight gain (1513.3g±9.83) were found for the higher supplemented group compared to the non-supplemented group (1441.0g ±4.04). Overall FCR was significantly (p< 0.05) lower for supplemented groups compared with the control group. The decreasing (p< 0.05) trend in FCR in supplemented groups was increasing the level of bovine animal blood plasma supplementation in the diet. The dressing percentage was significantly (P<0.05) higher for supplemented groups as compared to the control. Non-significant differences were observed in haemagglutination inhibition (HI) antibody titer against Newcastle disease and mortality among groups. It was concluded that animal blood plasma could be safely used in broiler ration for better performance without any loss to antibodies titer and mortality. Animal blood plasma has more capability to be used as an alternative and cheap source of protein in poultry ration.
