Abstract
The effect of varying dietary levels of defatted soybean meal
on the growth and survival of mrigal, Cirrhinus mrigala
(Hamilton) was investigated. In a feeding trial of 90 days,
three experimental diets containing soybean meal at 200, 300
and 400 g kg)1 level of incorporation were fed to quadruplicate
groups of 10 fish each. The conventional feed used in
India, consisting of a mixture of groundnut oil cake and rice
bran in 1 : 1 ratio served as the control. Best growth in terms
of percentage weight gain, specific growth rate, protein efficiency
ratio (PER), feed conversion ratio and survival rate
was obtained for the test diet with 354 g kg)1 crude protein
and with 400 g kg)1 soybean meal inclusion level. However,
no statistical significant difference was observed between the
three soybean-based diets, except for PER and survival rate.
Soybean meal is an easily available, acceptable and costeffective
protein source in formulated feeds for Indian major
carps. The results of the present study indicate that a diet of
350 g kg)1 overall protein with soybean meal included at
400 g kg)1 can elicit good growth response and survival in
mrigal.
