Animal demandingfeed availability balance control series studies (4): Software development for animalfeed balance calculation

A computer software for animalfeed balance calculation was developed. The designing approach, calculation principle, selection criteria and induction methods for key parameters were explained. Compared with the traditional animalfeed balance calculation method, the software took the consideration of the timelag problem and shortened the calculating period to a monthly basis to improve the accuracy for the calculation to timely match the feed available to the animal demand. The features of the main menu, major functions and hardware requirements for the software were described. Its friendly interface, easiness for operation, convenient reporting and mapping output functions were appraised. Key words: animalfeed balance management; animalfeed balance calculation; software development
