| 一.緒言現行的役馬飼養標準,為數甚多。由於工作的計算困難,大都祇對於某種農業情况,加以大約的估計,因此用量的大小極不一致,而又無適當可行的辦法加以比較,以便抉擇。此中情況,林敦氏(1950)有言,"最好的方法是按照下述的辦法來飼養,如感覺馬的體情退化則增加飼量,如馬有長肥的傾向則減少之"。同樣波波夫亦謂,"必須不斷地注意馬的體况,並根據觀察結果,經常調整馬的日糧"(1954)。似此,則役馬的飼養仍處於一種技術修養的狀態,談不到定額矣。本文的目的在提出一衡量工作的尺度,根據此尺度,測驗各家的標準,並從而求出一比較合理的標準,此標準不但要按照飼養乳牛的辦法,計役授糧,而且要應用簡便,易於實行。此外,不同輕重及種類的工作,經測定各種的常數以後,亦可以納入本方法之中,俟一一論及之。 |

| A NEW FEEDING STANDARD FOR DRAFT HORSES |
|
|
|
| Abstract: |
| The present paper gives a short but analytic survey of current feeding standards for draft horses, and draws attention to the fact that while these differ to a marked degree among them- selves, none gives a really satisfactory account of the amount of food to be fed a working animal on the basis of a given definite amount of work. This is presumably due to the lack of a simple, adequate unit for work, but the case is rendered the more acute by the employ- ment of such units as the foot-pound and the kilogra... |
