Response of Finisher Broiler Chickens Fed Graded Levels Of Bovine Blood Meal Diets On Growth And Blood Chemistry
Abstract
A total of sixty (60) broiler chickens 4 weeks old were used in a 28-day study. The chickens were randomly assigned to four dietary treatments (T1, T2, T3 and T4) in a Completely Randomized Design (CRD). Each dietary treatment was replicated three times and each replicate had 5 chickens. T1 (Control diet) contained 0% BBM while T2, T3, and T4 contained 5%, 10% and 15%, respectively. Data were collected on the feed intake and weight gain. Feed conversion ratio, daily Protein intake, and Protein efficiency ratio were calculated. Haemoglobin counts, packed cell volume, red blood cell, white blood cell, neutrophils, lymphocytes, monocytes and eosinophils were analyzed. Feed cost/kg, feed cost/kg weight gain/bird/treatment, total cost of production, net returns, total revenue and Cost-benefit ratios were derived from the Analysis. Data collected were subjected to Statistical Analysis using One-way Analysis of Variance (ANOVA). Statistical mean differences were separated using the Least Significant Difference (LSD). Results show that all the haematological indices of the chickens in different treatment groups were not significantly (P>0.05) different. There was no significant ((P>0.05) difference in all the growth performance parameters of the chickens except the total feed intake and average daily weight gain. The cost-benefit Analysis results show that feed cost/kg gain and total cost of production decreased as the levels of BBM increased. It is therefore concluded that a 15% optimal dietary inclusion of BBM is adequate to enhance growth without any adverse effect on the health of broiler chickens.
