Abstract

This study was carried out on Nile tilapia fry, which were fed for 8 weeks on 25 or 30% dietary crude protein (CP) and 0,1,5 or 10 g flavomycin (FM)/kg diet. The following results were obtained: 1. dietary FM inclusion improved daily gain of fish body weight, relative growth rate (RGR), specific growth rate (SGR), feed intake (FI), and feed conversion ratio (FCR), particularly at the digest rate (10 g/kg). It reduced mortality rate of the fish and improved also protein productive value, protein efficiency ratio, and energy utilization. 2. increasing dietary CP led to increased body weight of the
fish as well as body gain (as length and weight), RGR, SGR, FI, and FCR and reduced fat content of fish body.
