Abstract: The experiment was conducted at the nearby poultry farm of the College of Veterinary Science and Animal Husbandry, NDUAT, Kumarganj, Faizabad, UP, India. A total of 200 unsexed Vencob commercial broiler chicks were distributed to four treatment groups each made of 50 chicks in a 4-brooder rooms. All the fifty chicks from each treatment were divided to form 5 replicates of 10 chicks each in a Completely Randomized Design (CRD). The four treatment groups were supplemented with neem leaf powder @ 0g, 1g, 2g and 3g / kg of broiler ration respectively. The litter of each treatment group was mixed weekly with dry neem leaves @ 0g, 2g, 4g and 6g / sqft area. The fecal sample from each group was analyzed for parasitic eggs at every two weeks interval. The results of group treated with 2g NLP/kg feed showed maximum reduction of 62.5% while the group treated with 1 g NLP/kg feed showed maximum reduction of 44.44% and the group treated with 3g NLP/kg feed was the least potent showing 37.5% reduction of oocysts count. All these values were not comparable with the control groups of birds where no treatment was provided. The effect of neem leaf feeding and the effect of neem leaf application in the litter might have synergized the reduction of OPG count in the treatment groups under study.
