The purpose of this study was to build a diagnostic support
system for the operation profitability of breeding chicken
farms. By inputting records of the poultry farm and using the
high speed function of personal computer, a diagnostic report
for the operation profitability was given to act as a valuable
reference of decision-making. This system was designed with
the programming language of DBASE IV. The main menu of the
system was divided into six functions in terms of data input,
data modification, data searching, statistic reports, data
analysis, and system management. The system contains nine
records concerning hatchery, flock growth, egg production, farm
expenses, farm receipts, production plan, labors, vaccination,
and medical treatment records. The main analysis items of
operation profitability include fertility rate, hatchery rate,
growth rate, mortality, feed consumption, feed efficiency,
average weight, production rate, average egg weight, total cost,
total revenue, net profits, return-cost ratio, profit rate, cost
of eggs, and labor efficiency. The way to diagnose the
operation profitability is to compare current performance of the
farm with the criteria of evaluation and to list the difference
individually.According to the farm records, the system
calculates the profitability quickly, lists each report and farm
current situation, and gives a diagnostic report automatically
after analysis. Farm manager can therefore understand the
operation efficiency and economic profit, save the time in
calculating manually, and omit the boring calculation. The
system compares current performance with past records, and to
make the manager understand his farm current situation. A
function of comparison with other farm records to understand the
efficiency and inefficiency points of the farm are also
provided, and to be a reference of decision-making to improve
his business in the future.
