초록
Feasibility of the self-TMR mixing/feeding system for dairy farm in Korea was analyzed by comparing with a traditional feeding system. The total operating cost of self-TMR feeding system decreased with an increase of farm size. However, the cost was higher than that of traditional feeding system because of its high purchasing cost of TMR mixer as an initial investment. Profit per unit input of the TMR feeding system became greater over the traditional system when the farm size is larger than 17 heads due to more and better milk production. The profitable discrepancy became bigger as dairy farm size increases.
