Abstract

The purpose of this study was to evaluate the utilization of crude glycerin in replacement for ground corn on the growth performance, nutrient and energy digestibility, and the change of digestive tract. This study was divided into two experiments. The first experiment was a study on the growth performance by using mixed-gender eighty-four Thai indigenous chickens with an average age of 11 weeks. The second study focused on nutrients and energy digestibility and conducted using mixed-gender thirty Thai indigenous chickens with an average age of 7 weeks. The study on the change of digestive tract was used mixed genders twenty-four Thai indigenous chickens with an average age of 8 weeks. The experiments were assigned using completely randomized design. The levels of crude glycerin in the diet at 0, 4, and 8% resulted in no significant difference on the overall growth performance and production cost. However, during the second week of the experiment, the use of 8% crude glycerin affected the growth of the chicken including the decreases of the average daily gain, fat intake, crude fiber intake while truly digestible crude fiber increased. Meanwhile, truly digestible carbohydrate, nitrogen intake, and nitrogen balance declined. In addition, the utilization of crude glycerin at 4 and 8% in diet significantly increased the crop weight but the right ceca weight and liver length were decreased.
