Abstract
The ameliorative effect of a combined regime of vitamins A and E on fertility and hatchability was investigated in Anak 2000 breeders. Vitamin A and E individually administered at a dose rate of 0.125 ml/kg body weight intramuscularly produced an improvement in hatchability, fertility, and sperm quality. The percentage fertility (46%) and hatchability (40.5%) before vitamin A&E administration was compared to those of fertility (76.9%) and hatchability (76.8%) after vitamin administration and found to be statistically significant at p<0.05. From the findings of this study, we can therefore postulate that intramuscular administration of vitamin A and E during acute episode of nutritional hypovitaminosis provokes a quick and prompt response in birds
