Abstract
A 35-day feeding trials involving three hundred (300) 5 week old broilers was carried out in a completely randomized design to evaluate the performance, organ characteristics, nutrient utilization and economic analysis of broiler finishers fed diets containing a mixture of fermented dried bovine blood and rumen digesta (FBBRD) at dietary levels of 0, 5, 10, 15 and 20% respectively. At the end of the feeding trials, two birds were randomly selected from each treatment and transferred to a metabolism cage for faecal collection and determination of nutrient digestibility. Another set of five (5) birds were randomly selected from each treatment for carcass and organ weight evaluation. Birds on the test material performed generally better in all the parameters measured than the control group. There were no significant (P<0.05) difference among the groups in relative organ weight. The groups on the test materials (FBBRD) also recorded better nutrient nutrient utilization values than the control group. The results suggest that up to 20% inclusion level of FBBRD meal could be tolerated by broiler finisher without any adverse effects on performance.
