Development of a Computer Auxiliary Management System of Two Hundred Thousand Laying Hens Production

In the computer IBM-PC/XT, a mapping machine SPL-450, a printer M- 1724 and a Chinese software dBASE III were used to set up a dBASE for the management of laying hen production. Besides the translating and editing BASIC and the C language, a certain application of foreign software was also introduced and combination of PCNONLIN non-linear parameter software pocket with self-editing program was taken in order to apply to hen production. The dBASE was supplemented with the best feed formulas and such sub-systems as (1) statistical analysis of hen daily food-protein level in summer and hen daily food-energy-protein level in winter; (2) a model of color egg production curve drawn from minikin technique; (3)production statistical treatment; (4) production planning management; and (5) feed stock management. This paper elaborates a general development report on the application of the above-mentioned sub-systems to medium-and Large-sized mechanized chicken farms and on the improvement of their management.
