Dairy Farm Precision Management And Resource Matching

The purpose of dairy production is to maximize economic benefits, while the vast majority of revenue comes from milk sales, which is why people always take milk production as the most or the only indicator for dairy production and breeding. But people pay little attention to the improvement of its management, and the result is often counterproductive.Under this context, precision agriculture and precision animal husbandry theory is conceived and born. Currently, most of cows'production management mode is extensive, and there are many problems. Under this condition, based on the idea of precision animal husbandry, it is very necessary to determine an management mode, which fit to the development of modern animal husbandry.In this study, Lintao Gansu Province of China Animal Husbandry Co., Ltd. is taken as the template, combined with precise theory of animal husbandry on the basis of a large number of dairy production practices, we discussed the dairy management mode, and then raised the level of evaluation of dairy cattle management rules, and proposed some suggestions:â‘ ,accurate collection of production data;â‘¡,Key point control of cows'production cycle;â‘¢,Management level was measured by economic effects.Meanwhile, it is need to determinate trait indicators of reproductive performance and lactating performance, calculate the economic benefit of each cow in the lactation period, analyze the correlation between each trait, obtain each path coefficients of economic efficiency, count the contribution of each trait to economic efficiency. And then study the relations between 305d milk production quantity and the economic efficiency, determine the best match between the current management level and the resources, enable the cow productive forces to obtain the best display, maximize the economic efficiency. Determine the main constraint factors of ranch economic, offer the basis for the ranch manager. The result as follows:1. Under the current management level, the dry period is the main factor to restrict the economic benefits; 2. Cows economic exists roof effects, the mainly reason is the match between management and resources;3.2008,2009,6390kg and 8140kg respectively, milk yield is best suited to their level of management productivity; productive best when the greatest economic benefit.On this basis, we prepare a dairy management software precision to assist improvement of management level. The development trend of dairy cow is precision management. This study mainly researches the relation between the dairy cow's lactation performance, reproductive performance and economic benefits. In the process of precision management of dairy cow, there are many elements to be studied, such as cow comfort management, dairy nutrition management etc, and need further study in the future.
