Abstract |
The effects of graded levels of processed castor oil bean (Ricinus
communis L) meal (CBM) and DL-methionine on carcass and organ
weights of broiler finishers were investigated for 4 weeks. One hundred
and eighty six week old boiler birds (Anak strain) were randomly divided
into 12 groups of 15 birds each and assigned to 12 isocaloric (2.90 Mcal/kg
ME) and isonitrogenous (21.00% CP) diets in a 4 x 3 factorial
arrangement involving four CBM levels (0, 10, 15 and 20%)
and three DL-methionine levels (0, 0.25 and 0.5%). Each treatment
was replicated 3 times with 5 birds per replicate. At the 10th
week of the experiment, 3 birds per treatment (one per replicate) were
randomly selected, weighed and slaughtered for carcass and organ
evaluation. Results showed that body weight, carcass yield, organ and
relative organ weights reduced significantly (P<0.05) as the level of
CBM in the diets increased beyond 15%. However, the inclusion of DL-
methionine in the CBM-containing diets reversed the adverse effects
observed at the 15 and 20% CBM inclusion levels. It was concluded that
15% processed CBM supplemented
with DL-methionine can be
included in broiler finisher diet without adverse effects on
carcass and organ weights.
