Effect of Replacement of Maize Gluten with Rice Bran (5:0 and 1:4) Feed Supplement on Fish Growth in a Composite Culture

摘要

This experiment was conducted to evaluate comparative effect of replacement of maize gluten with rice bran feed supplement on fish growth in composite culture. Two earthen ponds, each measuring 30m x 16m x 1.5m (length x width x depth) were stocked with 100 Labeo rohita, 50 Cirrihina mrigla and 25 Ctenophayrngon idella. Pond P1 was provided maize gluten and rice bran with a ratio 5:0 whilst pond P2 was provided maize gluten and rice bran with a ratio 1:4. Average body weight gain, fork length and total length were affected significantly by replacing maize gluten with rice bran. Results indicated that it is better to supplement maize gluten (30% CP): rice bran 1:4 for more yield as compared to maize gluten (30% CP) alone.
