A total of 63 day-old straight
run Layer chicks up to 45 weeks of age on 3 isonitrogenous and isoenergetic
diets D1 (6% PC+ 0% SWP), D2 (0% PC+ 6% SWP),
and D3 (0% PC+ 8% SWP) were fed to observe the effect of
dietary SWP on growth and egg production performance. This study revealed
that profitability, growth and egg production performance of RIR pure
line were significantly (P< 0.01) higher in D2 dietary treatment
groups as compared to D1 and D3 treatment. No
significant difference (P< 0.05) in livability was found which could
be attributed to the dietary SWP levels. Feed cost/kg was gradually
declined on increasing dietary levels of SWP. The efficiency by the
birds receiving SWP were better as compared to the control. The result
of this study demonstrated that cheaper SWP could be an excellent substitute
of costly protein concentrate in formulating diets for layers leading
to increase profitability.]]>
