This experiment was conducted to investigate the compositions of minerals and amino acids in brequette ash absorbed with concentrated fish soluble and to study the effects of brequette ash-fish soluble absorption feed on growth performance of pigs. A total number of 10 pigs (Landrace (♀) × Berkshire (♂) were divided into 2 treatments which had 5 replicates per treatment and fed the experimental diets for a period of 84 days. The results obtained were summarized as follows : 1. As the levels of fish-solubles, which were absorpted to brequette ash, increased, the contents of minerals and amino acids increased. 2. Average daily gains of pigs fed brequette ash-fish soluble feed were higher compared to those of pigs fed control diet. And feed efficiency was unproved by adding brequette ash concentrated fish soluble to control diet. 3. In economic analysis, feed cost required per ㎏ body weight gain for pigs fed brequette ash absorbed with concentrated fish soluble was less than those for pigs fed control diet. And the periods to reach marketing weights (90㎏) were shorter in brequette ash absorbed with concentrated fish soluble treatment by 14 days than in control.
