TreatuuMit.— The treatment is wholly pieveutive and consists in avoid- 

 ing the feeding of slops containing these alkalies. 



Poisoning by Eating Cotton Seed.— Fatal results follow the feeding 

 of cotton seed, whether given ground, roasted, raw, boiled or as droppings 

 from cattle. Poisoning, however, is not always observed in hogs foHow- 

 ing cattle fed on this food stuff. The cause of the trouble has not been 

 discovered, all attempts at getting an active extract having proven un- 

 successful. 



Symptoms.— The evil effects are not noticed until several weeks, 

 usually four to eight, after using it as a food. In cases that have been 

 observed throughout the whole course, there is first a moping dullness, 

 staggering gait, labored breathing, spasmodic in character and usually 

 called thumps, loss of sight, restlessness, walking in a circle and running 

 into obstructions, lying down flat on the belly, and finally sudden ex-, 

 haustion and death. In the majority of cases the animals are found 

 dead in their beds or pens ten or twelve hours after they had apparently 

 been in the best of health. 



Lesions.— A post-mortem examination gives no definite lesions and 

 fails to shoAV any effect that might be attributed to the hulls. 



Treatment.- The only treatment that can be recommended is prevent- 

 ive. Avoid using cotton seed in any form as food for hogs for more than 

 two weeks at a time. 



Effects of Eating Wheat and Barley Beards.— Frequently w'heu hogs 

 are turned upon wheat or barley stubble some will die. The symptoms 

 which they will present will vary. In some cases it will be an intense 

 sore mouth, in others a general bowel disturbance, and again in others 

 loud and difficult breathing. 



Lesions. — Post-mortem lesions will show beards in the mouth, stomach 

 and windpipe. A roll of beards may form and get down by the side or 

 at the root of the tongue and penetrate the mpcous membrane. The ani- 

 mal can not get rid of them, and the parts become intensely swollen and 

 inflamed, interfering with eating and starvation may occur. Plugs of 

 beards may lodge at any point between the larynx and bronchi, produc- 

 ing loud, disti-essed breathing and coughing. In the stomach there may 

 be a slight inflammation of the lining membrane. Sometimes, however, 

 when beards lodge in the mucous membrane and do not soften and pass 

 away, the inflammation is serever. 



Treatment. — When the mouth becomes inflamed, the treatment is the 

 same as in simple stomati.tis. Plugs of beards when lodged in the mouth 

 can be removed. If lodged in the air passages, or stomach, they can not 

 be removed, and the animal dies from suffocation or an inflammation of 

 the parts. 



Effects of Ergot— Hogs may become poisoned by ergot if fed on 

 grains, such as rye screenings, containing a very large quantity of the
