Abstract
A study was carried out to determine the productive performance of starter chicks fed diets supplemented with graded levels of dry guava (Psidium guajava L) leaf meal (DGLM) as a phytogenic feed additive. The study was conducted at the livestock experimental unit of National Veterinary Research Institute Vom, Plateau State. A total of 240 unsexed day old cobb broiler chicks were used for the study for a period of 4 weeks. The chicks were randomly allotted to 4 dietary treatments (T1, T2, T3 and T4) comprising of 60 chicks per treatment. Each treatment was replicated thrice with 20 chicks of similar mean live weight per replicate using a completely randomized design (CRD). T1 (control), T2 ,T3 and T4 received 0g , 150g , 300g and 450g of DGLM per 100kg basal diets respectively. The diets were iso-nitrogenous and iso-caloric. The diets and water were served to the birds ad libitum. The research methodologies were carried out following standard protocols. Performance indices and cost analysis data were collected. Results showed that, though the average daily feed intakes of all the treatments were the same (P>0.05), the final body weights of birds fed T4 diets were significantly (P<0.05) higher than those fed other diets. Feed conversion ratio, protein efficiency ratio and feed cost N/kg weight gain followed similar trend as in body weight gain. The study concluded that supplementation at 450g of DGLM per 100kg in chick’s diets results in impressive productive performance.
