This study was carried out to develop the computer software system for the layer farm management by using microcomputer (IBM-P/C compatible). Pull-down system was adopted to develop the software system (LAMASystem Layer Management System) by using menu-driven method for the end-user lacked experience of` computer system. COBOL. and CLIPPER were selected as computer languages to develop the LAMASystem. The LAMASystem had primary menus which were ENTRY, DATA-INPUC, PLAN-OUTPUT, REPORT-OUTPUT, ANALYSIS-OUTPUT and each primary menu consisted of 31 kind sub-menus through hierarchical structure. Increasing the layer farm productivity was expected by applying the LAMASystem through systematic data collection and handling.
