Effect of Supplementation of Non Starch Polysaccharide Hydrolyzing Enzymes on Performance of Broilers

Two hundred and fifty one-day old Ven-Cobb straight run commercial broiler chicks were supplemented with the NSP hydrolyzing enzymes at 1X (HC) concentrations viz. (xylanase, -D-glucanase, cellulase, mannanase and pectinase @ 2400, 4800, 1800, 4800, and 2400 IU/kg respectively. The similar enzyme combination was supplemented @ 4800, 9600, 3600, 9600 and 4800 IU/kg respectively as 2X (HC) to the corn + soybean meal based standard diet. Similarly the corn + soybean meal diet was supplemented with NSP hydrolyzing enzymes at 1X (LC) viz. (xylanase, -D-glucanase, cellulase, mannanase and pectinase @ 400, 240, 200, 200, and 400 IU/kg respectively. The same NSP hydrolyzing enzyme combination was supplemented @ 800, 480, 400, 400 and 800 IU/Kg respectively as 2X (LC). The birds were weighed, wing banded and randomly distributed in to five experimental groups, with ten replicates and five birds in each replicate to assess the effect of the NSPHE combination on growth performance of broilers. Significant (Pless than0.05) differences were observed with the weekly body weight gain, feed intake, and feed conversion ratio when the birds were supplemented with NSP hydrolyzing enzymes at 1X (HC). However the NSP hydrolyzing enzymes did not influenced the overall performance of broilers when supplemented @ 2X (HC), 1X (LC) and 2X (LC) to the corn soybean meal based diets.
