Analysis of influence factors for cow breeding in Heilongjiang Province
摘要
Abstract
Dairy farmers need to understand the factors affecting the effectiveness of dairy farming and adjust the strategies of cow breeding.In this paper,the cost and benefit data of dairy cattle breeding were selected in Heilongjiang Province from 2004 to 2014.By multiple linear regression analysis,the results showed that the influence of raw milk output was 1.001,0.491 and 0.966,respectively on the small,medium and big-scale cow breeding profit.Deputy production effects of 3 scale farming profits were 0.948,2.7957 and 1.110,respectively.Changing feed and PPE depreciation could cause profit change for small-scale and big-scale cow breeding.The values of influence were -0.949,-0.993,-0.997 and-1.118,and health care cost and other charges only cause large-scale profit change,whose influence is 0.973 and-1.003,based on various influencing factors.Some suggestions are put forward to improve the benefit of dairy cattle breeding.关键词
