A total of 40 Issa brown point-of-lay birds at 20 weeks of age were assigned randomly into 5 treatments, 1, 2, 3, 4, 5 with 8 birds/treatment and 4 birds/replicate. Birds on each treatment were fed different diets containing Garcinia kola at 0 g/1000 g, 10 g/1000 g, 20 g/1000 g, 40 g/1000 g and 80 g/1000 g/kg weight of feed. The control diets did not contain Gracinia kola. The trial lasted for 8 weeks. There were no significant differences (p>0.05) in egg weight, yolk weight, yolk index, yolk length, yolk colour, yolk albumen ratio, shell weight, shell thickness and Haugh unit of the eggs. There were significant differences (p<0.05) in performances, albumen weight and yolk height. This study showed that Garcinia kola did not pose any deleterious effects to the birds even at 80 g/1000 g/kg inclusion level but performance and egg quality were best at 10 g/1000 g/kg of dietary inclusion.
