Experiment 1. The effect of natural zeolite supplementation on nutrient utilization of broilers was studied using sixteen 4-weeks old broilers (composed of equal numbers of males and females). They were randomly fed for five days isocaloric diets as follows. Diet 1: control (no natural zeolite), Diets 2, 3 and 4 supplemented with 1, 3 and 5 percent natural zeolite, respectively. The apparent net protein utilization (ANPU) and metabolizable energy (ME) of all the diets were not significantly different. However, supplementation of natural zeolite tended to increase apparent net protein utilization. Experiment 2. The effect of varying levels of natural zeolite on production performance, calcium and phosphorus in serum, abnormality of legs and feathers and ammonia level in the poultry house was studied, using 480 one-day old broilers. The chicks were randomly fed for seven weeks isocaloric diets as follow. Diet 1: Control (no zeolite), Diets 2, 3 and 4 supplemented with 1, 3 and 5 percent natural zeolite, respectively. The result indicated that body weight gain, feed efficiency and serum calcium were significantly different (P0.05) but feed intake, mortality rate and ammonia level were not significantly different. Supplementation of natural zeolite tended to increase feed intake, decrease mortality rate and ammonia level and to cause no abnormality of legs and feathers.
