Among the most important measures of precaution, is the separation of the sick from the healthy, and to disinfect thoroughly the buildings in which the infected have been. Straw, and when possible dung should be burned; if not, they should be buried together with the urine. The stalls should be thoroughly cleansed and then saturated with mercuric chloride (1 : 1000), or sulphuric acid (3 : 100), or a saturated solution of sulphate of copper. Here as elsewhere chloride of lime (4 oz. to the gallon) with as much quick lime as will make a good white wash, does admirably, as it is at once seen if any part has been missed. Esser remarked that the calves of cows that had been removed to another stable some time before parturition, usually remained healthy, provided they were kept from the other and sick calves. Lastly, it is important to use for breeding purposes such animals only as have a strong, vigorous constitution, and to furnish a healthful, abundant aliment and to allow a sufficient amount of exercise during gestation. Vigor and stamina are the great desiderata, but these are usually found with the darker colors. _Treatment._ The old treatment of eliminating offensive matter by a laxative is still good, and thus castor oil (2 ozs. for a foal or calf, 2 drs. for lamb), or rhubarb (1 dr. foal or calf, 1 scr. for lamb), or manna (½ oz, foal or calf, 1 dr., lamb), may be given with laudanum (1 dr., foal or calf, 10 drops, lamb), and salicylate of soda (16 grs., foal or calf, 5 grs.,lamb). The milk should be given boiled. An old and excellent remedy to follow the laxative is solution of rennet made by adding ⅛ of a calf’s abomasum to a quart of 20 per cent, alcohol (or sherry). A tablespoonful may be given with each meal. The value of this as an antiferment is liable to be overlooked, yet both the hydrochloric acid and pepsin are strongly antiseptic, and neither of these is produced to any extent in the diseased stomach. In addition to this ipecacuan has been used and by its stimulant action on both stomach and liver it furnishes the two most important natural disinfectants of the alimentary canal (foal or calf 1 dr., lamb 10 drops ipecacuan wine, thrice a day). In addition to these or separately, antiseptics, carminatives and astringents may be employed. An excellent preparation is prepared chalk 1 oz., white bismuth 1 oz., tincture of cinnamon 8 ozs., gum arabic ½ oz. A tablespoonful thrice a day will often check the disorder. Cadeac advises, subnitrate of bismuth 5 grains, salicylic acid 5 grains, naphthol 20 grains, syrup 150 grains, distilled water 100 grains. One or two tablespoonfuls in the mouth after each drink (foal or calf).
