  • Abstract:

There is persistent quest for alternative feed resources hence the need to explore the use of wastes from chicken processing
plants, which would otherwise constitute environmental pollutants. This study evaluated the replacement value of chicken
eviscerated waste meal (CEWM) for soyabean meal (SBM) in a maize-SBM diet, on an equal protein basis, in the diets of
broiler chickens. The experiment was arranged in completely randomized design with four replicates per dietary treatment
using two hundred (200) 4-week old broilers at 10 birds per replicate. A total of four diets and control were used for the
experiment. Diet A was the Control diet with SBM only. Diets B, C, D and E had equi-protein replacement of the dietary
SBM with CEWM at 25, 50, 75 and 100%, respectively. Feed and water were provided ad libitum. Growth performance,
carcass and organ characteristics as well as haematological variables of the chickens were evaluated. The results showed
that there were no significant (p>0.05) differences in the final live weights, weight gains, feed consumption and feed
conversion ratios of the birds due to the dietary treatments. The carcass parameters were not significantly (p>0.05)
influenced by the dietary treatments. The relative weights of the chickens’ abdominal fat increased with increasing dietary
CEWM and that of the gizzard were higher for chickens offered CEWM than the control. Inclusion of CEWM in the diets of
broiler finishers had no significant (p>0.05) effect on all the blood indices. It was concluded that CEWM could replace
SBM completely in maize-SBM finisher broiler diets (with 14% dietary SBM) without any adverse effects on performance
characteristics. However, adequate processing to avoid pathogenic organisms in the meal should be considered..
