Protein Digestibility of Different Animal and Plant Protein Sources for Labeo rohita Fingerlings

P. K. Sarker, S. Rahman, M. M. Rahman, S. C. Chakraborty and M. N. Islam

Abstract

A laboratory trial was conducted on the protein digestibility of rohu (Labeo rohita) fingerlings in a static indoor fish rearing water system of glass made aquaria (90 cm x 30 cm x 30 cm) for a period of 75 days. Each treatment had two replicates containing 12 fingerlings. Five experimental diets A, B, C, D and E were prepared from different combination of five major sources of protein viz., fish meal, protein concentrate, meat & bone meal, mix of animal protein sources and mix of plant protein sources each containing 33% dietary protein level. The apparent protein digestibility (APD) values of the above mentioned diets were 81.70, 78.66, 75.53, 72.53 and 69.96%.
