Abstract: To find out the influence of oral supplementation of vitamin A on minerals of sheep hair, six Barbari sheep selected randomly from the herd on the basis of various phenotypic traits and offered identical feed to meet out their daily nutritional requirements. The animals were given oral administration of vitamin A at the rate of 5000 IU per kg live weight in the morning daily. Hair were sampled from the neck shoulder, mid flank, ventral abdomen, croup and lateral thigh region on the days 00, 30, 60 and 90 of the experimental trial.
