چکیده مقاله :
This experiment was determined to investigate the effects of exogenous-enzyme addition to the high and low levels of metabolizable energy (ME), on performance, energy utilization and body composition of broiler chickens fed corn-soybean meal diets from 0 to 21 days of age. 240 one-d-old male Ross 308 broil-ers were used in a completely randomized 2 × 2 factorial design, with six replicate cages per treatment. Two metabolizable energy level: 3150 or 2750 kcal/kg and two enzyme (with xylanase beta-glucanase, and phy-tase activity) level: 0 and 200 mg/kg dry matter (DM) were used. There was a main effect of energy (P<0.05) on feed intake of broilers and feeding 2750 kcal/kg ME diet increased feed intake (FI) of broilers in the whole period. The addition of enzyme to 2750 kcal/kg ME diet significantly (P<0.05) improved the average daily gain (ADG) and feed conversion ratio (FCR) of broiler chickens on 0-21 days of age (P<0.05). While net energy for production (NEp), NE, ME, organic matter, and dry matter digestibility were improved (P<0.05) by supplementing both energy level diets with enzyme at 21 d, only addition of enzyme to 2750 kcal/kg ME diet reduced heat production (HP) of broilers in the total trial (P<0.05). On day 21, the amount of NE improvement by enzyme supplementation was greater than ME for 2750 and 3150 kcal/kg, respectively. This study showed that NE is a more sensitive energy utilization measure than ME for evaluating the response of broilers to enzyme supplementation, and the energy retained as fat and protein in the body carcass was higher for the birds fed lower energy diet supplemented with enzyme.
