86 THE RURAL EFFICIENCY GUIDE STOCK 



Treatment. Keep healthy animals 1 of all kinds away from infected cattle. 

 Keep people connected with other animals away from the premises. While 

 the affected cattle may recover in a few weeks, the virus may be carried 

 on them and the disease thus spread. Get rid of all cattle that have had the 

 disease. Disinfect with any of the following solutions : A 5 percent solution 

 of pure carbolic acid; standard chloride of lime, 1 pound to 3 gallons of 

 water; formaldehyde, 1 quart 40 percent solution to 5 gallons of water; or a 

 3 percent solution of cresol compound. Burn the manure and plow under. 

 Do not purchase other cattle for at least 60 days after disinfection. 



Flies Keeping Them Off Stock. 



The following is said to protect cows for a week : One pound common 

 laundry soap, 4 gallons water, 1 gallon crude petroleum, 4 ounces powdered 

 naphthalin. Cut the soap into thin shavings and dissolve in warm water; 

 then dissolve the naphthalin in the crude oil and mix the two solutions 

 thoroughly. Stir well before using and apply with a brush, or use 1 

 pound rancid lard and one-half pint kerosene. Mix into a creamy mass. 

 Recommended by Minnesota Experiment Station. A mixture of cottonseed oil 

 and pine tar has produced excellent results. Use every day or two. 



Frost Bites. 



A day or two after freezing, the ear becomes swollen and painful. The 

 dead part is cold and begins to shrivel. Mix one part each of turpentine, am- 

 monia and chloroform, then add six parts of sweet oil. Rub this on affected 

 part. It relieves pain and stimulates the circulation. 



Grubs in the Back. 



These grubs develop from the eggs of the heel fly or warble fly. The 

 fly resembles a small black bee. It appears early in summer and lays its 

 eggs on the skin of cattle. The usual mode of entrance is through the skin, 

 although the eggs or newly-hatch larvae may be taken into the mouth by the 

 cattle licking themselves. 



Symptoms. Conspicuous lumps form during the latter part of winter and 

 spring. 



Treatment. When the grubs have reached a late stage of development 

 they may be squeezed out and killed. When lumps are small, cut with a sharp 

 knife and press out the grub. You can kill the grubs by forcing grease or 

 oil into the openings of the lumps. The only objection is that the dead 

 grubs remain beneath the skin. 



Impaction of the Omasum or Third Stomach. 



This is caused by food clogged in third stomach resulting from eating 

 a lot of old dead hay in summer or extra dry feed in winter. 



Symptoms. There are sharp pains on right side and the animal has 

 considerable fever. No bloating is usually shown, animal does not like
