As a matter of fact many of the dairy barns where sanitation Is the primary object are nr.lie inexpensive. On the other hand if It Is to be convenient!) arranged to embody tho most accepted sanitary features, it Is very essential that some attention be given to the plana and specifications of the barn that is to house the dairy herd to the best advantage. Every detail of a new barn should be carefully care-fully worked out before actual construction con-struction takes place. The illustration here shown will, it Is hoped, give the builder some new ideas as to how the barn can bo made more sanitary. In building a dairy barn, or any other kind of a barn for that matter, the plans must be worked out to suit different conditions and locations. Hardly any two sltei would permit exactly the same plan being used. If wholesome and s'inltary milk Is to bo produced the farmer should realize that tho cow must bo kept out of the mud as nuch as possible. Conditions In and around the barn can, In many cases, be grt-itly Improved by draining and grading .Draining Is not of Itself sufficient, as Rie tramping of the cattle soon puddlti the surface, thus practically previn'lng the water from reaching the Ulet below. The barnyard shout.! have good slope, such m will lnsuie good surface drainage, and should hive a good top layer of gravel or cinders. In many places this may liivolo a great deal of work, but even if the grading cannot can-not all be done In one year arrangements arrange-ments should be made by which at I least part of It Is done every year. i ' ( ' i 1: if" cat not be laid on the fi"1 that we have no better dlsln- jic 'a' l th;.n good, old-fashioned sun-ei... sun-ei... For this reason In planning our barns much more attention should be paid to the quetlon of securing sufllclent light. It is said by authorities authori-ties on the sublect thi't four square feet of window light should be allowed for a;h cow In the barn, lxing windows win-dows reaching well to the celling have been found the tnoK satisfactory for the reason that the ll(,ht coming through them can reuch all parts of the barn better than If the short windows win-dows are used. It Is also of Importance to remember that there Is no better way of preventing the spread of tuberculosis tuber-culosis In our herds than by admitting admit-ting plenty of sunlight and fresh air Into the barn. The height to celling differs somewhat some-what according to different Ideas of the builder, but the height should bo sufllclent to give ample air space In the structure. ( , The important features of a good system of ventilation are that It provides pro-vides a constant supply of pure, fresh air, that the fresh air is admitted near the ceiling and that the impure air Is taken out near the floor. Tho fresh cold air should be admitted near tho celling, ho that It may, by contact with th warm air, be tempered before reaching the rows. Vy fcrcing tlio Impure air out near the floor less heat Is lost and, as Is claimed by most authorities, au-thorities, the major part of the Impure air Is found neurit he floor where thfl cows are constantly deporting many of the linpurltha :lven off In breathing. breath-ing. A damp stalle favors the breed lng of disease geiis. A good system of ventilation will tarry away all extra moisture. No system of ventilation can be successful in a barn where the cracks and crevices In the walls permit per-mit crosscurrents to Interfere with the work of the ventilating l!un. |
