Since the mungbean meal vermicelli by-product (MBMV) had very low nutrient digestibility values, this experiment was conducted to study the effect of amino acid supplementation of high MBMV rations on production performance and carcass characteristic of growing-finishing pigs. Thirty-two purebred Large White barrows averaging 30 kg were randomly assigned into four dietary treatments composed of corn-soy diet (positive control) and three treatment groups of 30 percent MBMV diet containing with and without (negative control : MBMV) amino acid balance based on NRC (1988) requirement (MBMVAA) and with high nutrient density (105 percent of corn-soy diet : hi-den MBMV). Results indicated that addition of amino acid in low protein diet with high MBMV failed to improve production performance and carcass characteristic of the animals. Amino acids supplementation at level equivalent to 105 percent NRC requirement improve the production performance and carcass characteristic in terms of average feeding period, daily gain, protein efficiency ratio, feed conversion ratio, loin eye area and lean cut yield of the high level MBMV diet in growing-finishing pigs, but was not comparable to corn-soy diet. It requires higher nutrient density in the diet especially crude protein or increase more amino acid level supplementation in high MBMV diet.
