The experiment was conducted on 350 one day old straight run broiler chicks consisting of seven treatment groups having ten replicates with five chicks each soybean meal was replaced with alternate protein meal (APM) viz. Guar meal (GM), Rapeseed meal (RSM) and Cotton seed meal (CSM) each at 3 (total 9 percent) and 6 percent level (total 18 percent) with or without the supplementation of Non starch polysaccharide (NSP) hydrolyzing enzymes. The 3 percent APM containing diet was supplemented with two levels of the NSP hydrolyzing enzymes i.e. (xylanase, ß-D-glucanase, cellulase, mannanase and pectinase @ 3200, 4000, 1520, 8000, and 3200 IU/kg (1X concentration) and 6400, 8000, 3040, 16000 and 6400 IU/kg (2X concentration) respectively. Similarly the 6 percent APM containg diet was supplemented with two levels of the NSP hydrolyzing enzymes i.e. (xylanase, ß-D-glucanase, cellulase, mannanase and pectinase @ 3200, 4000, 1520, 8000, and 3200 IU/kg (1X concentration) and 6400, 8000, 3040, 16000 and 6400 IU/kg (2X concentration) respectively . The 3 % APM diet supplemented with NSP hydrolyzing enzymes at 1X and 2X levels had shown significantly higher body weight gain (BWG) compared with that of control. However, the 6% APM control diet has witnessed significantly lower BWG throughout the experimental period. Similarly, the 6 % APM diet supplemented with 2X NSP hydrolyzing enzymes has not shown any significant differences in BWG throughout the experimental period. Feed intake was significantly higher (P<0.05) in 6 % APM control diet followed by 3 % APM control diet. Supplementation of NSP hydrolyzing enzymes at 1X and 2Xlevels influenced the FCR (P<0.05) of broilers.
