| Popis: | A feeding trial using corn distiller's dried grain with solubles (DDGS) was conducted to evaluate the nutritional value of DDGS and effects of lysine and methionine supplementation in DDGS-based diets on the performance of rainbow trout, Oncorhynchus mykiss. The DDGS-based diets were made such that DDGS was used at 7.5% (diet 2), 15% (diet 3), and 22.5% (diet 4) inclusion levels without supplementing crystalline L-lysine-HCl and DL-methionine, and was used at 7.5% (diet 5), 15% (diet 6), and 22.5% (diet 7) with lysine and methionine supplementation in a 2 × 3 factorial design. A fish meal-based diet (diet 1) was used as a control. The control and lysine and methionine supplemented diets contained 2.2% lysine and 1.1% methionine. A total of 630 fish (initial body weight 49.8 g) were randomly stocked into twenty-one, 150-L tanks with 30 fish/tank and 3 tanks/diet. Fish were fed to apparent satiation 3 times/day and 6 days/week. After a 6-week growth period, weight gain (WG) offish fed diets 1 to 7 ... |
