TMR 사양시스템은 사료효율을 유지하면서 사료 섭취량을 조절하여 언제든지 균일한 영양소가 함유된 사료를 자유채식 시킬 수 있으므로 능력이 좋은 소 일수록 TMR이 필요하게 된다. 보다 질 좋은 TMR 제조를 위해서는 각 원료사료 특히 조사료의 중요성을 인식해야 하겠다. 조사료의 품질과 조사료의 입자도를 고려하는 것이 젖소의 생선성 향상과 밀접한 관계가 있으므로 양질의 조사료 확보에 힘써야 할 것이다.

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.

Currently, there was no producing system of TMR for pig feeding in Korea. In this study, we examined unrolling, cutting, and softening for the round bale silage. We designed and developed the prototype system of round bale silage for pig feeding. Unroll method were lower chain conveying and upper belt conveying which includes an hydraulic vertical fodder knife. Gathering and cutting method were rotating auger and flywheel which have 10 cutters, input roller of 280 rpm, and cutter rotating speed of 1,750 rpm. Softening device was rotating hammer in inclined cylinder adjustable to $25^{\circ}C$ and rotating speed up to 1,300 rpm. The prototype system was integrated working for unrolling, cutting, and softening. We found that when the round bale silage in unrolling apparatus cut length of 20 cm to input cutting apparatus, the cutting performance was well in continuous working up to input rate of 1,000 kg/h, the softening apparatus was working well.
