PREVENTION, SYMPTOMS AND TREATMENT t Q^ 



sterile milking tube into each quarter of the udder. The injection 

 should be made slowly and carefully, and after gentle manipulation 

 of the gland the solution should be removed in about fifteen minutes. 

 If suppuration threatens, then the application of 10 per cent, binio- 

 dide of mercury ointment will hasten suppuration. 



The presence of the interstitial form, with its surrounding zone 

 of inflammatory edema, will lead us to secure drainage of the 

 swollen area in the belly and perineum by punctures. These may 

 best be done by the actual cautery in points so placed as to avoid 

 the veins. A 10 per cent, boric acid ointment should then be applied. 

 Suppuration calls for incision and drainage, and, if very extensive 

 or if gangrene occur, removal of the udder in part, or as a whole, 

 is in order. 



The chronic form offers great danger of human infection if 

 milk containing pus and cocci is ingested by man. Cows with sup- 

 purating chronic mammitis should be made ready for the butcher. 

 Removal of the teats with scissors aids drainage and has been done 

 to facilitate fattening. 



Contagious mammitis is prevented by having a separate milker 

 for diseased cows and by segregation of the patients until well. 

 In mild cases intramammary injections of boric acid (4 per cent.) 

 may be effectual; in more severe, 1/10 to T / 2 per cent, solutions of 

 sodium fluoride are said by Moussu to be most efficient. 



Food and water must be restricted during active mammitis 

 to limit the function of the gland. Prevention of the disease is 

 attained by general cleanliness of the barn and animal by the use 

 of proper stalls, so that the animal's udders are not stepped upon; 

 and by treatment of all abrasions of the teats. 



Mange— Acariasis — Scabies — Itch — Scab. 



Mange is produced by an order of animal parasites — Acarina, 

 mites or ticks. Three genera are recognized, as ( 1 ) sarcoptes, or 

 burrowing mites, which burrow under the epidermis, feed, and
