Abstract
A total of 192 3-d-old male broiler chickens (Arbor Acres) were random ly assigned to six dietary treatments with eight replicates of four bi rds each per treatment. The treatments consisted of five levels (0, 50 , 75, 100 and 125 U kg(-1)) of pectinase enzyme and a combination of p ectinase (50 U kg(-1)) and a-galactosidase (6250 U kg(-1)) enzymes. Th e performance trial lasted for 2 wk. At the end of 2 wk, excreta were collected on three diets to determine nitrogen-corrected apparent meta bolizable energy (AME(n)). Growth rate, feed intake and feed conversio n of birds fed pea diets supplemented with graded levels of pectinase enzyme were not different from their counterparts fed a diet without p ectinase supplementation; however, growth rate tended to be improved ( P = 0.11). Also, the AME(n) values of these diets were not affected. C ompared with the control diet, addition of a combination of pectinase and alpha-galactosidase tended to improve growth rate (P = 0.06).
