Abstract

In order to examine and investigate the XYLANASE and bmannanase enzymes effects on broiler chick's PERFORMANCE, 360 commercial hybrid of Ross were used in experiment. This experiment was carried out in 42 days in experimental farm of varamin azad university- Faculty of agriculture in 2007. The BROILER CHICKS were allocated randomly in 8 groups in 24 pens with 15 chicks in each pen as a complete randomized design on basis of Factorial 2x2x2. (In two levels of METABOLIZABLE ENERGY and two types of enzymes in two different levels). Each treatment fed with especial ration from day one. Daily weight gain (G), feed intake (FI) and Feed conversion ration (FCR) were measured weekly (3, 4, 5, and 6). The results obtained from this experiment indicated that METABOLIZABLE ENERGY (ME) levels had no effect on FCR and FI, but high ME levels had significant effect on G and caused it to increase. bmannanase enzyme existence had increasing effect on FI and G more than other enzymes, and in examining the interaction between ME and enzyme, the results indicated that in most of the cases, treatments which had XYLANASE enzyme in low level of ME, caused intake to decrease and treatment which had bmannanase enzyme in low level of ME, caused FI to increase. METABOLIZABLE ENERGY, enzyme existence and the interaction between them had no significant effect on the mortality.
