Abstract:The apparent digestibility(AD) of dry matter, protein, amino acids and phosphorus of seven feed ingredients for bluntnose black bream( Yih ) were determined by using 0.5 as an indicator. The test diets consisted of 70meat and bone meal, soybean meal,peanut meal, cottonseed meal, distillers dried grains with solubles(DDGS) and rapeseed meal. The fish averaging ( ×0.8 m ×0.8 m), and the fecal samples were collected by abdominal pressure method after five weeks. The results showed that apparent digestibility of dry matter, protein, amino acids and phosphorus of seven feed ingredients were , 78.66%–93.63%, 80.12%–94.83% and 3.21%–48.02%, respectively. Among the seven feed ingredients, the highest apparent digestibility of protein and total amino acids was in rapeseed meal; then the apparent digestibilityof fish meal was close to that of peanut meal and soybean meal; and the lowest was in meat and bone meal. Apparent digestibility of phosphorus was the highest in DDGS, and the lowest in rapeseed meal and meat and bone meal, and others were 11.81%–29.10%. In conclusion, rapeseed meal, soybean meal, peanut meal can be used as high quality plant protein source to serve as alternative fishmeal for , and the apparent digestibility of phosphorus was the highest in seven feed ingredients. Therefore, DDGS can be used as a
