Some of the commonest diseases 

 Cattle which American cattlemen have to

abortion, foot and mouth disease, foot 

 rot, hemorrhagic septicemia and tuberculosis, while the 

 following are the commonest parasites which have to be 

 combated ; Texas fever tick, lice, screw worms, ox warble 

 and mange. 



LUMP JAW. Lump jaw is a chronic non-infectious 

 disease that affects the jaws of cattle and the udders of 

 swine. It is caused by a fungus that is frequently found 

 on barley beards, oat stubble and various grasses, although 

 it does not grow outside of the animal body. It appears 

 as a hard tumor-like swelling on the jaw in the early 

 stages of the disease, but later becomes ulcerated from 

 the inside, causing slobbering and difficulty in chewing. 

 The animal becomes emaciated and frequently starves 

 to death. The most satisfactory way to handle the 

 animal is to begin fattening it at the first signs of disease 

 and ship to market before the affection becomes too 

 marked. Such animals are subjected to rigid examination 

 after death and if the disease is localized in the head the 

 animal is passed as fit for food. 



BLACKLEG. This is a highly contagious disease that 

 affects cattle between the ages of six and twenty-four 

 months. It is usually fatal in the course of twelve to 

 thirty-six hours after the animal first shows signs of 

 sickness. However, the animal may have been infected 

 from three to five days previous to the first symptoms. 

 The animal shows a high fever, loss of appetite and great 

 depression, while it usually stops chewing its cud in the 

 very earliest stages. Swellings appear over the heavily 

 muscled parts of the body and if one strokes the skin in 

 these parts a distinct crackling is heard and felt. There 

 is no satisfactory remedy and the best method is preven-
