Two basal diets (wheat and maize) with or without the new enzyme mixture were used for starter, grower and finisher phases. Each diet was offered to 5 replicates each 80 chicks in a randomized complete block design (4 blocks of 4 diets each, n = 1600). Enzyme used in the study was produced by Framelco BV, the Netherlands and the diet also produced by Arkervaat-Twente, the Netherlands and each diet was split into two portions: the new enzyme mixture product was added to one portion per basal diet and the diets were pelleted with steam addition. Data was analyzed using GLM procedure of SAS (2010) for a randomized complete block design, with level of significance set at p = 0.05. Body weight and feed intake were recorded at 10, 28 and 35 days and body weight gain and feed conversion ration were calculated in the aforementioned periods. Body weight (BW) and Body weight gain (BWG) were significantly higher (P<0.0001) for birds fed maize based diet at 10, 28 and 35; 10, 28 and from 0 to 35 days, respectively. Enzyme supplementation had no significant effect (P>0.05) on Feed Intake (FI) during the entire experimental period. No significant differences (P>0.05) were observed for Feed Conversion Ratio (FCR) for broilers fed either maize or wheat based diets at 10, 35 and from 0 to 35 days; however, FCR were significantly higher (P<0.0001) for broilers fed maize based diet with enzyme mixture than broilers fed maize without enzyme during the growing period. In conclusion, the new enzyme mixture showed improvement in body weight (3%) and body weight gain (3.5%) for broiler fed maize based diet without effect on feed intake, whereas the test product failed to demonstrate improvement in growth parameters for broilers fed wheat based diet.41enbriolerenzyme mixtureperformanceDEENK Témalista::Mezőgazdaságtudomány
