Abstract

Abstract: The study was conducted to validate the assigned matrix value of commercially available phytase in broiler chickens by determining the effect of supplementing broiler diets with commercially available phytase on the growth performance (i.e. feed efficiency and body weight) and carcass yield of broilers (i.e. dressing percentage and weight of cuts parts). Analysis of Variance and Duncan's Multiple Range Test (DMRT) were used to determine significant treatment means. Results show that there were differences (p<0.05) on the average body weights and feed efficiency of the broiler chickens across treatments with varying phosphorus and phytase levels. However, no difference (p>0.05) was observed with feed consumption of the chickens across treatments. Differences (p<0.05) were also observed in the dressing percentages and some cut-up parts (i.e. breast, thigh, and leg) of the broiler chickens across treatments attributed to the phytase enzyme used. Moreover, it can be concluded that the assigned matrix values for 100g/ton and 200g/ton phytase are valid. With the results obtained, use of the enzyme with the 100g/ton matrix value for commercial broiler production is recommended.
