Causes: Irritants; ferments; noose on jaw; specific poisons. Symptoms: Careful feeding; thirst; frothy lips; champ jaws; redness; swelling; fœtor. Treatment: Cooling, astringent, antiseptic lotions; mushy food; derivative; tonics.

Causes. Swine suffer from simple stomatitis when exposed to thermal, mechanical or chemical irritants. Food that is too hot, or that which is hard and fibrous, or that which contains spikes and awns, capable of entering and irritating gland ducts or sores, or food which is fermented or putrid, food or medicine of an irritant character. The habit of catching and holding swine with a running noose over the upper jaw, and the forcing of the jaws apart with a piece of wood in search of the cysticercus cellulosa are further causes. In several specific infectious diseases inflammation of the mucous membrane with eruption or erosion is not uncommon. Thus aphthous fever is marked by vesicular eruption, muguet by epithelial proliferation and desquamation, hog cholera and swine plague by circumscribed spots of necrosis and erosion. Patches of false membrane are not unknown, and local anthrax, tubercle and actinomycosis are to be met with. Inflammation may start from decaying teeth.

Symptoms are like as in other animals, refusal of food, or a disposition to eat sparingly, to select soft or liquid aliments, to swallow hard materials half chewed or to drop them, to champ the jaws, and to seek cold water. Accumulation of froth around the lips is often seen, and the mouth is red, angry, dry, and hot, and exhales a bad odor.

Treatment does not differ materially from that adopted in other animals. Cooling, astringent, antiseptic lotions, honey and vinegar, and in case of spongy or eroded mucosa, tincture of myrrh daily or oftener. Soft feeding, gruels, pulped roots, or well kept ensilage may be used, and clean, cool water should be constantly within reach. In case of overloaded stomach or indigestion a laxative followed by bitter tonics will be in order.

CATARRHAL STOMATITIS OF BIRDS. PIP.

Causes: hurried breathing; local irritants; exposure; filthy roost. Symptoms: gaping; roupy cry; epithelial pellicle on tongue, larnyx. or angle of the bill. Treatment: pick off pellicle; smear it often with glycerized antiseptic. Remove accessory and exciting causes.

This form of inflammation of the tongue of birds is characterized by the increased production and desiccation of the epithelium so that it takes on a horny appearance. According to Cadeac it may accompany various inflammatory affections of the air passages, which cause hurried breathing with persistently open bill, and thus entail evaporation of the moisture. More commonly it has its primary cause in local inflammation of the surface in connection with damp, cold, draughty hen-roosts, and above all, the accumulation of decomposing manure and the exhalation of impure gas. Even in such cases the abnormal breathing with the bill open is an accessory cause of the affection.

Symptoms. The breathing with open bill should lead to examination of the tongue, but above all if at intervals the bird with a sudden jerk of the head emits a loud shrill, raucous sound, which reminds one of the cough of croup. The tip and sides of the tongue are found to be the seat of a hard, dry, and closely adherent epithelial pellicle, which suggests a false membrane.

Treatment. The common recourse is to pick or scrape off the indurated epithelial mass, leaving a raw, bleeding surface exposed. This is then treated with a solution of borax, or chlorate of potash. Cadeac deprecates this treatment as useless and dangerous, and advises the disintegration of the dry epithelial mass with a needle taking care not to prick nor scratch the subjacent sensitive tissue, and to wash with a 5 per cent. solution of chlorate of potash. A still more humane and effective method is to make a solution of hyposulphite of soda in glycerine and brush over the affected surface at frequent intervals. This may be conveniently applied through the drinking water.

In case of implication of the lower air passages or lungs, the treatment must be directed to them, and soft, warm, sloppy food and the inhalation of water vapor will prove of great advantage. Secure clean, sweet, dry pens, pure air, and sunshine. (See pseudo membranous enteritis.)
