Effect of Yucca schidigera and Natural Zeolite on Broiler Performance

Abstract

The effects of dietary supplementation of Yucca schidigera and natural zeolite on broile r performance, ammonia concentration of broiler house, litter moisture, fecal dry matter and fecal crude ash were investigated. One day-old, nine hundred and sixty unsexed broiler chicks obtained from a commercial hatchery were divided into 4 treatment groups of 240 birds each. Birds were randomly assigned to the four treatment diets, consist of control, 15 g natural zeolite/kg, 25 g natural zeolite/kg and 120 mg Yucca schidigera/kg. Body weights of birds were significantly (P<0.05) different among the treatments, birds fed on diet containing 120 mg Yucca schidigera /kg being the highest and this treatment was followed by chicks fed diet control at days 21 to 42 and 42 day. Feed conversion ratio was not affected by the supplementation of nd
