Sheep farm reproduction for the main places, so make sure sheep pen set reasonable. At the same time, we should reduce/avoid adverse effects caused by the surroundings of the flock, and conducive to the sheep’s normal growth and reproduction.Goats engineering technology mainly includes process of design and construction, building facilities, environmental control, waste treatment technology, sheep product processing technology, such as sheep breeding engineering technology is connected to the biological technology. This paper integrates the related theories to propose the countermeasures that will be meaningful.展开更多

Currently, the pig breeding mode dominated by individual households leads to acute fluctuation of pig price to some extent. The scale expansion of recent decade intensified the fluc- tuation of pig price in the short term but will stabilize the price in the long term. Therefore. it is necessary to expand breeding scale for maintaining long-term price stability and the optimal scale should be chosen according to the circumstances to ensure the social benefit maximization.展开更多
