One hundred and sixty eight (168) 4-week old broiler chicks were used in a 28-day feeding trial to evaluate growth performance and some haematological changes associated with yam peel meal inclusions in finisher diet of broiler chicks in Ghana. The birds were separated into four treatment groups (each group consisting of three replicates) which were respectively fed diets containing 0%, 5%, 10% and 15% YPM, manufactured exclusively from local products. Feeding and water supply were ad libitum. Routine vaccination and medication procedures were strictly observed. Hematological parameters including RBC, WBC, PCV, Hgb, MCH, together with absolute count of heterophils, lymphocytes, monocytes, eosinophils and basophils were determined by routine methods. Data collected on performance and carcass parameters included initial weight, final weight, weight gain, feed intake, feed conversion ratio, dressed weight, gizzard weight (full and empty), intestine weight (full and empty), heart weight, liver weight. Results showed that birds fed 0% YPM made significantly (P |
