Abstract
Pouteria campechiana (Canistel) is an under-utilized tree fruit grown naturally in many tropical and sub-tropical regions. Objective of this study was to determine the effects of dietary Canistel fruit meal (CFM) on growth and carcass parameters of 3-6 week old broiler chicken. Ninety broiler chicks in 30 pens, were fed one of the five iso- proteomic broiler finisher diets containing either 0 (control), 5, 10, 15 and 20% of CFM from day 21 to 42. The dietary level of CFM had no significant (P>0.05) effects on final live weight on day 42, weight gain from day 21 -42, water intake, carcass weight and dressing percentage. However, feed conversion ratio (FCR) of the birds given control diet was significantly lower than that of the birds given diets with CFM. The weights of the visceral organs and the length of the small intestine in relation to empty carcass weight were not significantly different among treatments. The abdominal fat pad weight of the birds given 10%CFM was significantly lower than that of the birds given diet without CFM. It was concluded that the up to 20%CFM can be included in broiler finisher diets without any adverse effects on health, mortality, growth and carcass parameters.

Summary
The energy requirement of commercial poultry feeds are mainly supplied with cereals such as maize, wheat, barley and their by products. Maize; the principle energy source of poultry feeds is increasingly been used for biofuel production as well. Scanes (2008) reported that increased feed ingredient prices have severe negative impacts on livestock producers and the consumer, those in developing countries. In these circumstances, screening, evaluation and the utilization of alternative or non conventional feed ingredients for poultry have been identified as a key research priority (Sheldon 1998 2000)
