PREVENTION, SYMPTOMS AND TREATMENT

Eruption about the feet with loss of hoofs occasionally is seen. 

 Mortality from 50-90 per cent. 



Treatment. — The treatment is very unsatisfactory and only 

 symptomatic. Prevention in the way of clean, dry, well-ventilated 

 stables and the removal of infected soil under cow stalls is im- 

 portant. Isolation of the sick and disinfection of discharges are 

 advisable. No specific is known. The internal use of creolin in 

 2-dram doses twice daily in a pint of milk is said to be useful. 

 Also irrigation of the nasal chambers with a 2 per cent, solution of 

 lysol. Steaming, bathing the eyes with cold water and treatment 

 as for conjunctivitis; alcohol, good feeding with milk and gruels, 

 cold to head with head symptoms, enemata or oil for constipation, 

 and other measures directed to special symptoms as they arise, con- 

 stitute the treatment. 



The discharge from eyes and nose is greater and contagion 

 less than in rinderpest, and in the latter the horns are not lost. 



Mammitis — Mastitis — Garget. 



Inflammation of the udder occurs from infection through the 

 teat or abrasions of the teat, through over-activity and distension 

 of the gland, and as a result of general infection. It occurs during 

 lactation unless traumatic. 



Acute mastitis has two forms : Primary, affecting gland tissue, 

 known, if mild, as catarrhal; if severe, as parenchymatous. If the 

 connective tissue is involved the inflammation spreads to surround- 

 ing parts and we have the interstitial form. 



Symptoms. — The udder becomes hot, swollen, tender and red- 

 dened, in one or more quarters, and there is more or less fever and 

 general disturbance. If the interstitial form predominates there is 

 apt to be higher fever and the tissues surrounding the udder are 

 swollen, tender and pit on pressure. In severe cases the gland be- 

 comes of a dusky hue, and suppuration, and rarely gangrene and 

 death, ensue. The milk is variously altered and may be thin, blue, 

 and contain curds, or be bloody and fetid. It is unfit for food of
