%X the objective of the experiment was to determine the apparent metabolizable energy corrected for nitrogen (amen) of a glycerin product derived from biodiesel production for broilers. a number of 35 male ross 308 broilers, with 35 days of age was fed ad libitum diets containing 0, 5, 10, 15, or 20% glycerin. amen was determined using total excreta collection, with four days of adaptation and three days of collection. increasing glycerin intakes resulted in increased water excretion. glycerin amen varied as a function of dietary inclusion levels, and a cubic equation was identified by regression analysis. maximum amen level- 4890 kcal/kg dm- was obtained with 15% glycerin inclusion. however, this level caused excessive water excretion, making its use unpractical.
