    abstract = {The effects of different inclusion levels of <I>Garcinia kola</I> on performance and egg quality parameters of layers were investigated for 8 weeks. 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 <I> Garcinia  kola</I>  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&gt;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&lt;0.05) in performances, albumen weight and yolk height. This study showed that <I>Garcinia kola</I> 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.}
