Raising broiler performance through xylanase targeting diets
Research clarifying the mechanisms by which xylanases improve nutrient digestibility in non-viscous diets suggests that this variability may be due to either poor targeting of the xylanase, or possible under- or overdosing, and this has implications for its use in viscous diets.
Addition of an intrinsically thermostable xylanase at 0, 8,000 or 16,000 U/kg incrementally increased PYY secretion in both a standard diet and in a negative control diet with energy content reduced by 100 kcal/kg.
