Prevent ion. Prevention is of far more value in this disease 

 than all the treatment you can give. Cows that are heavy milk- 

 ers and big fat should be cut short on their feed for a couple of 

 weeks previous to calving. Plenty of salt and all the water they 

 will drink is beneficial. A dose of epsom salts, as No. 1, should 

 be given about one day before the cow is expected to come in. 

 If she comes in unexpectedly, don't delay to give her the physic 

 as soon as found, if she is fat and a big milker. One ounce of 

 nitrate of potash may be given every day for several days instead 

 of the salts. If the udder (bag) becomes much distended before 

 calving, it should be milked every day, as it gives relief to the 

 cow and wards oif disease. Plenty of exercise, light feed, and a 

 dose of salts, are the great preventatives against this dread dis- 

 ease. Many a poor cow is killed through kindness by her owner 

 feeding her very heavy previous to calving, so she will give a 

 good flow of milk when she comes in. 



M A MMITIS GARGET. 



Garget, more properly known as Mammitis, consists of in- 

 flammation of the inamary gland (bag), and is brought about in 

 various ways. Some cases are very mild and pass off in a day 

 or two, while others are more severe, and may either destroy the 

 udder or kill the cow. Any one or more of the quarters may be 

 affected, and sometimes the whole bag is involved. Garget gen- 

 erally comes on shortly after calving, but may take place even 

 before calving, or any time while the cow is giving milk. 



Causes. Garget may be caused by an injury to the udder, 

 such as kicks, blows, wounds from briars or thorns, lying <'n 

 sharp objects, etc. A frequent cause of the trouble is irregular 

 milking, and not completely emptying the bag at each milking. 

 Over-driving with distended udder may cause it, and also it very 

 often follows calving by the fever in the system settling in the
