ABSTRACT: This study was conducted at the Poultry Unit of the Department of Animal Health and Production Technology, Akperan Orshi Polytechnic, Yandev, Benue State – Nigeria to investigate the effects of supplemental Vitamin A (retinol) and Vitamin E (dl- alpha tocopheryl acetate) on performance parameters: hen day production, feed intake, feed conversion ratio, egg weight, haugh unit score, shell thickness, loss in body weight and mortality of Isa brown hens reared under the humid tropical conditions of Yandev, Benue State Nigeria. The study lasted for 24 weeks. A total......

ABSTRACT: Cassava (Manihot esculenta Crantz) is a very important food crop that is propagated vegetatively by roots in most parts of the tropical and sub-tropical regions of the world. Africa produces over 54% of the world cassava and Nigeria is at the top of world production with 57 million tonnes. Like most Vegetative Propagated Crops (VPCs), this method of asexual reproduction makes them more vulnerable to pest and disease attacks. The bulkiness of cassava stems that serve as the planting materials (seed) together with low multiplication rate and perishability tend.....
