Growth Performance and Resistance toStreptococcus iniaeof Juvenile Nile Tilapia (Oreochromis niloticus) Fed Diets Supplemented with GroBiotic-A and Brewtech Dried Brewers Yeast

This study was conducted to evaluate the effect of dietary levels of Brewtech dried brewers yeast (BY) and GroBiotic-A (GB) on growth performance, proximate body composition, immune response, and resistance of juvenile Nile tilapia to Streptococcus iniae challenge. A practical basal (control) diet formulated to contain approximately 32% crude protein and 6% lipid was supplemented with 1% and 2% of BY or GB. Each diet was fed to Nile tilapia in...
