中加動物健康啟動項目由中加瘦肉型豬項目和中加奶牛育種綜合項目合作實施，項目投入包括技術援助培訓和加方技術援助所需的運轉費用和旅行費用，為獲得預期項目活動的完成，額外的經費已撥款給兩個執行項目。In this paper, we first analyze the input and output as well as cost - benefit rate of chinese livestock industry by the example of hog, beef, mutton and dairy cow. then, we choose the samples from different regions in different time, use the stochastic production frontier suggested by battese and coelli ( 1992 ), which is aimed at the panel data ( balanced or unbalanced ), and make the econometric analysis for the growth of hog, beef, mutton, and dairy cow. different from the former research for livestock industry, the efficiency measurement theory is introdiced into the growth model and the tfp is dissolved into technical advancement, technological efficiency and residual, the translog production function is used to make the estimation more precised
本文首先以生豬，肉牛、肉羊和奶牛為例對近年來我國畜牧業的投入產出和成本收益狀況進行了分析，然後採用battese和coelli在1992年提出的針對混合數據（ paneldata ）的隨機邊界生產函數形式，在不同地區選取一定的樣本，利用樣本省的時間序列與截面混合數據，對生豬，肉牛，肉羊和奶牛的增長因素進行了分析，與以往對于畜牧業增長研究不同的是，將效率測算理論引入生產增長模型，把全要素生產率分解為技術進步、技術效率和殘差項，並採取了更加符合實際的超越對數函數形式，使傳統上使用的索洛余值法得到改進，更深層次的剖析了我國畜牧業目前的增長方式。However, modern sows, with a leaner genotype and the superior reproductive performance we have come to expect, must be managed differently from their counterparts of 20 years ago, since they begin their reproductive life with fewer body reserves
然而，我們現在所期盼的瘦肉型高繁殖性能的母豬，必須要與20年前的養殖管理有所區別，因為它們要用更少的體儲備來實現高繁殖性能。
