碩士 === 國立中興大學 === 畜產學系 === 91 === Followed by the development of computer technology and Internet communication, integration in technological information and animal production has become a major research area for quite a long while. Computerized feed formulation program running on the personal computer had been established for a long time, and present target is to transfer this kind of DOS into Windows. The further study is to set the program running on the Internet to provide users could apply it more widespread and more conveniently. The purpose of this study was made to establish a system which could calculate feed formulation online and is available on the Internet to animal producer, feed manufacturer and education. The revised simplex method of linear programming model was used in this system. Feed formulation calculator online was designed by adopting Microsoft Windows 2000 Server as operation system and was written with ASP.NET coordinated with Microsoft Access database. This system includes seven segments in terms of setting up basic data (personal information about user, ingredients, nutrient items, feed composition, feed price and category of animal), formulation calculation, least cost feed formulation, reports (ingredients, nutrient items, feed composition, feed price, conclusion of formulation calculation and least cost feed formulation), user’s manual, supplementary booklet and contact programmer. Users must go through registration before login this system and could input data on the forms of active pages directly. By selecting one kind of animal and its stage, choosing or editing usage of feed ingredients, formulation calculation was then processed. By choosing category of feed and its limited usage, nutrient requirement and total amount of feed, the least cost feed formulation was therefore derived. This system also provides shadow price and opportunity cost for sensitivity analysis and helps users to make decision as a reference source. Key words：Feed formulation, Internet, Calculation online.
