The research of the optimal managerial model to promote competitive ability

　　The study based on the managerially recording accounts (July,2009~June,2010) on the 25 dairy farms. There was not great difference of the managerial profits between the southern and middle northern Taiwan. View from the comparison of the farm size, the size 150~199 heads on feeding was the highest managerial efficiency among the 4 farm sizes, because its net revenue and farm earnings per head of dairy cattle and per kg of raw milk were the highest. Next was the farm size 100~149 heads on feeding. If the labor and capital were restricted, the size of 100~149 heads on feeding was more suitable to raise dairy cattle. But it must be enhanced on the pure technical efficiency to offset the fault of the uneconomic size. All the 4 sizes of dairy cattle on feeding, the managerial profits were all positive. The small size of dairy cattle farm can be sustainable mainly based on enhancement on the pure technical efficiency and increasing the production of milking cow. Under the condition of the feed price in the world increased dramatically, it is the best way for the farmer to use domestic forage instead of using imported forage.
