Abstract
A six weeks feeding trial was conducted to evaluate the effect of
replacement of soybean meal (SBM) with cottonseed meal (CSM) with or
without addition of ferrous sulphate in white Pekin ducks. One hundred
one-day old white Pekin ducks were divided into five groups. Group (1) fed
standard basal diet (control), group (2) fed diet where 20% of SBM was
replaced by CSM (CSM20), group (3) fed diet 2+ ferrous sulphate
(CSM20+), group (4) fed diet where 41% of SBM was replaced by CSM
(CSM41) and group (5) fed diet 4+ferrous sulphate(CSM41+). On 21 and
42 days of age blood samples were collected from different groups.
Replacement of 20% or 41% of SBM by CSM had no encouraging effect
on the growth performance. Furthermore, there were a significant decrease
in red blood cells count, hemoglobin, packed cell volume, total protein and
plasma reduced glutathione in CSM20 and CSM41 groups compared with
control group. Meanwhile, there were significant increases in serum ALT
and AST activity in the same groups. Addition of ferrous sulphate to
(CSM20+ and CSM41+) alleviates the adverse effect of gossypol on growth
performance, blood picture and organ functions.
