FIFTY-SECOND ANNUAL CONVENTION 231 



ing on rich feeds. Sometimes garget seems to develop with- 

 out any apparent cause. Very often a sore on the end of 

 the teat will lead to udder infection and garget. 



Treatment consists of giving a dose of Epsom salt or 

 other purgative, and putting hot applications on the af- 

 fected parts several times a day for at least 30 minutes at a 

 time. The Epsom salt should be given as a drench. (Page 

 230.) After these applications the udder should be wiped 

 dry, and camphorated oil applied and rubbed in thoroughly. 



Cawpox 



This is an infectious disease which causes character- 

 istic sores on the udder and teats. Tenderness and redness 

 of the teats are first noticed, which is followed by eruption 

 of grayish-red nodules. A vesicle or blister forms in the 

 center of the nodule in about 10 days and in another 3 days 

 the blister breaks, discharges a yellowish serum, and then 

 a scab forms. 



Treatment consists of healing the sores left by the 

 blisters. Zinc ointment is a very good remedy, acting not 

 only as a disinfectant but also keeping the affected parts 

 soft, thus preventing cracking and bleeding. Since this 

 disease is commonly carried from one cow to another by the 

 milkers, the affected animal or animals should be milked 

 last; and, as a further safeguard, the hands should be dis- 

 infected after milking each cow in the herd. 



Foul Foot 



This trouble is experienced in many herds. It is thought 

 to be most frequently caused by infections from stable filth 

 while standing in wet, dirty places, or from foreign matter 

 becoming wedged between the claws. The hind feet are 

 most likely to be affected. The animal seems to suffer when 

 walking on the sore foot, and the region of the foot is in-. 

 flamed and swollen. When the soreness has advanced, there 

 may be sloughing off of the membrane between the claws, 

 which has an offensive odor. The foot should be thoroughly 

 cleaned, and if only slightly inflamed can be washed in a
