摘要

Day old Japanese quail chicks (n=150) were randomly allocated to 5 treatment groups with 3 replicates of 10 chicks in each. Five iso-caloric and iso-nitrogenous diets (T_1-T_5) were formulated, T_1 as control, T_2-T_5 contained graded levels of enzymephytase i.e. 125, 250, 375 and 500g/ton of feed. The available P content was 0.50% in T_1 and 0.40% in T_2-T_5. Supplementation of phytase significantly (P<0.05) increased the mean body weight in all the treatment groups and highest weight was recordedin group T_4 where diet was supplemented with 375 g phytase/ton of feed. Significant (P<0.05) reduction in the feed intake was reported in groups fed diet supplemented with phytase during 22-42 d period. There was significant (P<0.05) improvement in FCRduring 5th and 6th weeks period in all the treatment groups as compared to control. The percent N and Ca retention was more in group T4 but difference amongst the groups were not significant. The P retention was significantly (P<0.05) higher in group T_4and T_5 as compared to other groups. The length of duodenum was maximum in group T_4 and differed significantly (P<0.05) with all other groups. The overall cost involved in raising a bird from 0-42 days was Rs. 9.70, 9.16, 9.14, 9.10 and 9.13 in T_1 toT_5 respectively. The study revealed that supplementation of phytase at 375g/ton feed result into maximum gain with better feed conversion ratio and the diet was also most economical.
