This indicates that the improvement in the production parameters was
not consistent with increased dietary levels of yeast supplementation, since
the lowest response was obtained by the highest dietary supplementation(0.06%), and the highest response by the lowest supplementation. and The
lowest yeast supplementation also resulted in higher hot and cold carcass
weights and increased the gizzard, caeca and liver weights, which may
suggest increased digestibility and metabolism and hence a higher efficiency
of feed and nutrients utilization. The present experiment is, however, rather
limited in scope and cannot adequately answer these questions, but it can give
good indications for further research on the subject.
