Abstract

The present study was carried out to investigate the effect of phytase and/or citric acid (CA) on productive performance and blood phosphorus (P) in broiler chicks. For this purpose, 120 male chicks 8 days old were divided into 4 groups with 3 replicate cages having 10 birds in each. The first group was fed on a basal diet without any additives and kept as a control, the second, third and forth groups were fed on a basal ration supplemented with phytase (0.1g/ kg), CA (10g/kg) or phytase (0.1 g/kg) plus CA (10g/ kg), respectively. The results revealed that both feed additives produced a significant improvement in body weight (BW), body weight gain (BWG), feed conversion ratio (FCR) and feed efficiency (FE). All supplemented groups exhibited a significant decrease in FCR and a significant increase in FE at 24-40 days of age. There were no significant difference in the average feed intake (FI) between control group and groups supplemented with phytase or CA. However, FI in group supplemented with mixed additives was significantly lower than other groups at 24-40 days of age. Phytase supplemented group exhibited the highest level of serum P during the whole sampling periods. It was significantly higher than all experimental groups. Moreover, the overall mean of serum P was significantly higher in group supplemented with CA or mixed additives than control group. It is concluded that both phytase and CA improve growth performance of broilers and liberate the phytate-bound P, making P more available to birds.
