TREATMENT.—All antiseptic precautions should be carried out in this operation, as boiling the instruments and then covering them with Carbolated Vaseline. Then with a hidden bistoury or a knife concealed in a tube, force upward into the teat, then press out the little blade and draw the instrument down the teat, making about four incisions equal distance apart around the inner surface of the teat. The use of self-retaining teat dilators prevents the contraction of the cut surface. Permit them to remain in the teat for two weeks, removing them only when the milk is being stripped from the teat. Always place them in boiling water and cover with Carbolated Vaseline before inserting. HOLLOW HORN. Horns of the cattle tribe are normally hollow, although a core extends well into the horn. This, however, is merely a prolongation of a porous bone of the head which affords a point for the horns’ attachment, consequently when a cow is sick and the temperature is elevated, the horns are naturally hot, it being the symptom of a disease and not a disease of itself, should be treated under its special heading. The supposed disease “Hollow Horn” once upon a time was treated by boring a hole into the horn with a small gimlet and pouring Turpentine into the opening. This treatment is useless and harmful. It produces inflammation of the frontal sinuses of the head and chances are death of the animal will follow as a result of the treatment and not of the disease. INDIGESTION. CAUSE.—Animals with a voracious appetite will overload their stomachs with food that is hard to digest or is decomposed, causing the organs of assimilation to become weakened, sluggish and incapable of doing their proper work. SYMPTOMS.—The animal ceases to ruminate (chew its cud); stands quietly, hair rough, nose dry, temperature elevated one to two degrees, breathing usually faster than normal with slight grunts at each expiration of air from the lungs. The secretions of milk are suddenly diminished. If the hand is placed against the left side and quickly removed, a marked depression or pit will remain, which shows that the paunch is full of undigested food. Bloating is also frequently accompanied by indigestion.
