The Planning For Dairy Cow Raising Area And The Optimization Design On Cowshed Structure In Cold Area

At present, dairy cattle are usually bred in China by individual household. Human and dairy cattle are living in a single courtyard. Breeding scale is small, breeding mode is coarse and the breeding efficiency is low. In order to improve the living conditions and economic efficiency of farmers, the breeding status has to be improved as the expansion of construction of new socialist countryside.Dairy cattle breeding sections mode, which is a transitional breeding mode in our country, in the precondition of present breeding scale, the construction and scale development of dairy cattle breeding sections can be improved. The unit productivity of dairy cattle and quality of coarse dairy can be improved also. It is very important to increase the regional economic and accelerate the development of dairy industry.In this paper,in order to guide the study of farming researchers, we carried out an investigation on the representative dairy farming district of Heilongjiang province, on the basis of investigation and study, we pointed out the problems in the application of dairy farming district in Heilongjiang province, and puts forward the countermeasures,Starting from the overall, we studied on the farming mode of dairy farming district which is a special dairy breeding mode in China. We studied a variety of subjects about the construction of the dairy farming districts, including site selection, breeding process, milking process, ventilation, daylight, protection against the moisture, pollution disposal, environmental greening, and so on. In this paper, new breeding modes and measures are advanced to ensure the sustainable development according to the fact of national cold areas. The advanced technologies, establishments and experience of development counties are used to as references.This topic aims at reducing material cost in the process of cow house construction, through the establishment of mathematical model, the portal frames of adult dairy cowshed have been optimized by finite element method. The optimal distance of column and combination of gradient have been figured out under the same load. It provides the theoretical calculation for the portal frames of adult dairy cowshed.A scientific dairy cattle breeding mode is advanced to improve the living conditions, enhance the social service system of agriculture socialization, accelerate the regulation of industry conFig.uration of agriculture and increase the production of farmers. It is a probable breeding mode in cold regions.
