A study was conducted to investigate the effect of supplementing earthworm meal on the growth performance and nutrient digestibility of feed in broiler chicks. A total of 120 broiler chicks at 7 days of age were fed the experimental diets containing 0％(Control), 0.2％ and 0.4％ of earthworm meal for 6 weeks. When fed on both starter and finisher diets, the body weight gain and amount of feed intake were significantly higher (P<0.05) in the chicks fed 0.4％ of earthworm meal than those fed 0％ and 0.2％ of earthworm meal. There were no significantly differences in feed. conversion ratio and mortality among the treatments. When fed on both starter and finisher diets, digestibility of dry matter of feed was not affected by the dietary treatment, but crude fat and crude ash digestibilities of feed were tend to increased in chicks fed earthworm meal Digestibility of crude protein of feed in chicks fed 0.4％ of earthworm meal was significantly(P<0.05) improved as compared with those in 0.2％ or control group. These results indicated that the dietary supplementations of 0.4％ earthworm meal were effective in improve digestibility of crude protein of diet resulted improved broiler performance if.. broiler chicks.
