| Summary: | This experiment was conducted to evaluate the effect of supplementing enzyme
cocktail on growth performance, digestibility of nutrients, and monosaccharide
concentration in ileum and ceca of broiler chickens fed wheat-based diets. A
total of 600 male broilers (42.26 ± 1.76 g, 0 day old) were used for 35
days of feeding trial consisting of 2 phases (starter phase from d 0 to 21 and
finisher phase from d 21 to 35). Four dietary treatments were prepared based on
wheat diets containing four levels of enzyme cocktail supplementation at 0, 0.2,
0.3, and 20 g/kg. Overall, dietary enzyme cocktail supplementation decreased
feed conversion ratio (linear p = 0.007; quadratic
p = 0.013) and improved (linear p
< 0.05) the apparent ileal digestibility of dry matter (DM), crude
protein, and soluble and insoluble non-starch polysaccharides. The apparent
total tract digestibility of DM and gross energy were increased (linear
p < 0.01) with increasing supplementation levels of
the dietary enzyme cocktail. The concentrations of arabinose, xylose, mannose,
and glucose in ileal digesta were linearly increased (p
< 0.01) with increasing enzyme cocktail supplementation levels. In
addition, the quadratic effect was observed (quadratic p
= 0.046) in mannose concentration of ileal digesta. The concentration of
arabinose, xylose, mannose, and galactose in cecal digesta was increased (linear
p < 0.05) with increasing dietary enzyme cocktail
supplementation levels. The supplementation of enzyme cocktail efficiently
increased the utilization of nutrients in broiler and there was no adverse
effects of high dosage supplementation level. |
