The experiment also showed that most horses would not touch the white beans at all, or only unwillingly, and the best proved to be either the green Smyrna or brown Dutch beans, which for the same weight and nutritive value bulked bigger, for instance, than the peas, and were very willingly eaten. Peas and beans as a ration alone were found not to answer, as the horse misses the mechanical action--irritation of the bowel and stomach--and requires also certain chemical constituents present in oats to assist digestion. Even with the proportion of oats and beans actually used--seventy-six to seventy-eight oats to sixty beans--it was found advisable to increase the 'Rauffutter' ration to replace the missing oat-husks. But to provide this addition there were ample means, since the manure fund of the regiment, or of the squadron, was available; and in spite of the increased ration it became possible to make savings which in a single year sufficed to build a spacious riding-school, and thus contributed in another way to the training and general efficiency of the squadrons. In the third year the price of oats fell, and that of the other feed rose; hence, and for other reasons also, the conversion of the oat ration into other more nourishing materials had to be abandoned, although it would still have been possible to maintain a considerable increase in the nutritive value of the food issued. To keep the ration up to approximately the same level as in the preceding year, recourse had to be had to other means. It was found by experiment that a couple of pounds of straw per horse could easily be saved per day, and again ample funds for a supplement to the ration were available, a measure particularly applicable when the price of straw rules high. This year, too, as the expenditure on the riding-school was closed, the manure fund was also available, and the horses did nearly as well as before. I would not maintain that similar results are everywhere obtainable. The price of grains varies; the receipts from manure are everywhere different; in some garrisons peas and beans are difficult to obtain; the cost of transport also fluctuates. But all this is no reason why we should not seize an advantage even if we cannot always retain it. Even a few years of more and better food bring about an improvement in the horses, which lasts for a considerable time, and every effort, therefore, should be made to obtain these advantages offered by price variations whenever it is possible to do so.
