EVALUATION OF THE COMBINATION OF AMYLASE, XYLANASE, CELULASE AND BETA- GLUCANASE ON BROILER PERFORMANCE

The effect of three NSP-enzyme blends on performance of broilers consuming different type of diets was evaluated. A corn-soy diet (CSD), triticale diet (TD) and a triticaleoat (TOD) diet, with or without specific enzyme supplementation were formulated following the recommendations of the Ross 308 management guide. Each enzyme supplementation was designed considering the NSP content of the diet and added on top. Amylase (A), B-glucanase (BG), cellulase (C), protease (P) and xylanases (X) were used for the blend. Minimum activities per g for CSD, TD and TOD NSP enzymes formulation were (X:11.240 BG:196 C:200 A:32 P:120.000), (X:11.300 BG:140C:200A:20 P: 120.000) and (X:11.300 BG:210 C:200 A:40 P:120.000) respectively. A two-phase program was used; starter diets were fed from 0 to 10 d and the grower diet from 11 to 21 d. Each diet was fed to 8 replicate pens of 6 broilers each. Body weight (BW) and feed intake was recorded at day 0 and at the end of each experimental phase, feed conversion (FCR) was calculated. All experimental data was statistically analyzed by ANOVA using the GLM procedure of SAS. FCR ratio was reduced by the enzyme complex on three cases. FCR reduction for the TD, TOD and CSD diets were 4, 1 and 3 point respectively compared with their control diets. There were no statistical differences on BW for any of the dietary treatments. The data suggest that the use of NSP enzyme improved nutrient utilization of the diet.
