Over the past three decades, the feedstuff industry has developed and grown rapidly in Taiwan due to improvement in nutritional design, formulation of feed recipes and management technology. This excellent performance was recognized by the United States Department of Agriculture (USDA). Such performance seemed to be able to ameliorate in deficit between U.S.A. and Taiwan, R.O.C. However, after participating in World Trade Organization (W.T.O.), many industries including feedstuff in Taiwan might have changed drastically for competition and survival in the international trade. In this study, the feedstuff industry has been analyzed and characterized into five categories: individual proprietorship, reprocessing manufactory, niche manufactory, medium sized manufactory and consortium. The individual proprietorship will take full advantages at low cost and law taxes to survive and compete in feedstuff industry. The failure of reprocessing manufactory, in addition to lacking in technical development and research, could be account for illegality in this country. The niche manufactory could expand much more business itself and be capable of having the potency for competition. The medium sized manufactory could be better organized by working together as partnership to satisfy supply and demand. The resulting development of this type of business might turned out to be as good as speculated. However, consortium has to be the best one for competition by grouping-organization aspect and it will have a progressive development and investment potential in feedstuff industry in Taiwan after participating in W.T.O.
