DISEASES AND TREATMENT OF CATTLE 
391 
Bathe the bag twice a day with warm water and vinegar, 
after bathing apply white liniment and then oil the bag with 
-lard to keep it soft. It is advisable in very bad cases to let 
that quarter of the bag go dry as soon as possible. 
2. Bloody Milk. 
Causes. — Any injury to the bag, getting cold in it, or 
eating irritating weeds may cause it. 
Treatment.- — Give the following: 
Epsom Salts 1 pound. 
Nitrate of Potash or Saltpetre 1 teaspoonful. 
Mix in a quart of lukewarm water and give as a drench. 
Give a teaspoonful of saltpetre in a mash every night. After 
milking bathe the bag with warm water, wipe dry and apply 
white liniment, then oil the bag with lard or goose grease, 
and the milk will soon be all right. If caused from eating 
irritating plants, put the cow in another pasture. 
3. Blue Milk. 
In many cases the milk is watery looking and very blue. 
Causes. — Minute germs, called bacillus cyanogenus, cause 
this by getting up into the teat. The only way to be sure of 
these germs is to examine the milk with a microscope. 
Treatment. — With a small glass syringe inserted into the 
passage of the teat inject some of the following each time 
after milking: 
Hyposulphite of Soda 1 dram. 
Water 1 pint. 
Shake well before injecting, and after a few injections 
the milk will be all right. 
4. Stringy Milk. 
Causes. — Swallowing small germs while drinking out of 
stagnant pools of water will cause stringy milk. 
Symptoms. — A few days after the germs are swallowed 
the cow's milk is curdy and stringy looking, mix^d with 
water, and comes out in jerks when milking. It is like this 
for a few days, then gets all right for a week or so when it 
comes on again. Generally two or three cows out of a large 
herd are affected in the same way. 
Treatment. — If caused by drinking out of low springs or 
pools keep the cows away from the water by fencing it off.
