DISEASES OF ANIMALS 165 



Swelling Along Milk Vein. 



Just before calving my cow developed what at the time seemed to. 

 me to be a rupture of the navel, but a veterinarian said it was noft 

 a rupture. Since calving the swelling spread lengthwise of the body 

 and now extends from her forelegs to her udder along the milk vein. 

 at the navel it forms a sac which seems to be filled with a liquid, and 

 the whole vein is much enlarged. 



The heifer has been infected through a wound, probably a scratch. 

 Have a graduate veterinarian lance the sac immediately to provide drain- 

 age and then syringe the cut with an antiseptic. This treatment should 

 stop all spread of the infection. While he is doing this it would be well 

 to test for tuberculosis by the intradermal method. 



Swelling on Cow's Leg. 



My cow has a swelling on the inside hock joint. It looks and feels 

 like a bog spavin on a horse's leg. The cow is not very lame, but she 

 don't stand all her weight on that leg very long. 



Apply Lugol's solution of iodine to the swollen joint and rub in thor- 

 oughly with a tooth brush once a day. If skin becomes blistered wait till 

 inflammation subsides before continuing to apply. 



Cow With Sores on Under Side. 



/ have a cotv that has small sores upon either side of tail and under 

 her flank, behind her front shoulder, and upon her belly, which she 

 licks and keeps raw. I can heal them up for a short time with axle 

 grease but not permanently. 



Put a halter on the cow and surcingle. Attach halter-ring to sur- 

 cingle by a stick passed between the front legs. This will prevent licking 

 of sores which will not heal while being licked. Paint sores once or 

 twice daily with equal parts tincture iodine and compound tincture 

 benzoin. 



Pus Bag on Shoulder. 



A lump the size of a man's fist appeared six weeks ago on the 

 point of my cow's shoulder. I blistered it three times. It became soft 

 and I lanced it. A lot of matter ran out; but it has swollen hard to\ 

 its former size. 



Lance again at its lowest point and make a large incision. Syringe 

 out cavity once or twice daily with a solution of potassium permanga- 

 nate one teaspoonful to the gallon of water. 



A Mouth Trouble. 



/ have a Jersey cozv that dribbles and froths at the mouth and grinds 

 her teeth a good deal. Her coat is in good condition, but she does oV 

 attempt to eat any grass, though she is always ready for her hay and 

 eats it well.
