About This Book

This work is a practical veterinary manual that describes the anatomy of dairy cattle and the causes, symptoms, prevention, and treatment of many diseases. Entries cover common conditions—abscesses, abortions, eye paralysis, anthrax, and others—presenting likely origins, diagnostic signs, preventive measures, and step-by-step remedies, including field treatments, disinfection, and medical dosing guidance. Organized for students and practitioners, it emphasizes clear, concise instructions for early recognition, management, and hygienic control of infectious and noninfectious problems, with attention to stable care, feeding, and hands-on procedures to restore animal health and limit contagion.

CATARACT OF THE EYE.

Cause.—Is due to deep seated inflammation of the eye produced by an injury or weakened condition of the optic nerve.

Symptoms.—If the pupil of one of the eyes appears larger than the other it is well to make a careful examination, as this is the first sign of Cataract. If such a condition is neglected, partial or complete blindness will follow and a white, pearly deposit can be seen on the lens of the eye.

Treatment.—Very unsatisfactory unless treated carefully when the first signs are noticed. Place the animal in a darkened stable. Feed clean, sloppy food and it may be necessary to give a physic consisting of two drams of Aloin, two drams of Pulv. Ginger, placed in a capsule and given with capsule gun. The following ointment: Yellow Oxide of Mercury, four grains; Lanolin, one ounce, should be mixed well and applied to the eye two or three times a day.
