Study of Digital Management System of Milking Process on Large-Sized Dairy Farm

摘要

This study was to supply the systemic and full milking process data to support the implementation of both dairy herd improvement(DHI)and digital feeding of dairy cattle.This study designed the relational structured database and developed a set of digital management information system on milking process of intensive dairy farm using Visual Basic 6.0,Access databases,and Crystal report combining the milking characteristics of a grown cow,such as quality and sanitation testing indexes of raw milk.The system supplies a series of convenient,intelligent input interfaces of crude datum,and can count,analyze,and graphically show milking datum based on different types and different parities of cows or herds in a specific duration,and can dynamically produce some important derived data,such as days of grown cow, daily average of milk production of grown cow,days of cow milk production,and daily average of milking cow production; and can carry out all-pervasive data mining.With the help of system analysis and software design techniques,it is possible to realize precision farming for a dairy cattle herd based on whole digital management of milking process and realtime prediction on nutrient requirements and ration of dairy cattle,as well as dairy herd improvement.
