COITAL EXANTHEMA OF HORNED CATTLE. 



It is stated in Friedberger and Frohner's works on pathology 

 and therapeutics of the domestic animals that this disease is 

 more frequent in cattle than in horses simply on account of 

 their greater number. 



It is very contagious, as all the cows of a village may be 

 infected by one bull, and it is said that it is communicated by 

 friction of diseased against healthy cows, and by continual 

 wagging of the tail. In oxen Numann has observed the 

 eruption around the anus and sheath. Armbruster states that 

 the contagion is conveyed by wooden drains — when animals lie 

 down, their genitals coming in contact with these drains — when 

 these are contaminated by diseased discharges. Sclnieiper says 

 that the disease may affect the same subject several times at 

 short intervals. 



The symptoms are similar to those observed in the mare. 

 There is intense pruritis, vaginitis with redness and tumefac- 

 tion, muco-albuminous secretion ; membrane covered with dark 

 red spots, vesicles, and pustules of various sizes, which rapidly 

 ulcerate, the discharge from which contaminates the perineal 

 region and tail, drying up, forming crusts; micturition is 

 difficult, and manipulation causes much pain. The appetite, 

 secretion of milk, and other signs of general disturbance are 

 frequently present. The duration of the disease seems to vary 

 from eight to fifteen days, and more rarely from three to four 

 weeks. Some cows abort. In the bull there is much tumefac- 

 tion of the genitals, the penis studded with pimples, and there 

 is a discharge of a yellowish purulent material from the 

 urethra ; phymosis is frequent ; erection causes the ulcers to 

 bleed ; there is more or less constipation and loss of appetite. 



Local antiseptic and astringent treatment is recommended.
