DISEASES OF THE DIGESTIVE TRACT 93 



eat little or nothing; thirst is extreme in some 

 cases. The bird may die in two or three days or 

 it may live for two or three weeks. 



Postmortem Findings. — In fatal cases the most 

 noticeable alterations are in the intestinal tract 

 and the liver. Upon 

 opening the small 

 intestines, areas of 

 inflammation are 

 noted, and occa- 

 sionally a small 

 hemorrhage is 

 found. Microscopic 

 e X a m i n ation of 

 stained se c t i o n s 

 from the vital or- 

 gans (liver, kid- 

 ney, etc.) reveals 

 r etrogress ive 

 changes ; cloudy 

 swelling being most 

 marked. Fig. 33 

 illustrates one of 

 these cases. 



Treatment — Give 

 the same treatment as that given for blackhead 

 in turkeys and for fowl cholera. (See pages 90 

 and 83.) 



White Diarrhea 



The loss to American poultry raisers from white 

 diarrhea is greater than from anything else, per- 

 haps greater than from all other infectious dis- 

 eases combined. It strikes at the root of the 

 poultry industry ; no one can successfully conduct 

 the business if he is unable to rear a reasonable 

 number of chicks annually.
