twice a week for the next few weeks: Zinc sulphocarbolate, 

 fifteen grains; sodium and calcium sulphocarbolate, of each 

 seven and one-half grains; bichlorid of mercury, six grains, 

 and citric acid, three grains. This quantity was dissolved in 

 a gallon of water. The result was that eighty per cent of the 

 next hatch was saved. 



A diet of sour milk in white diarrhea and other bowel ail- 

 ments, of a similar nature, has given excellent results. ^ Cul- 

 tures of the Bacillus huhjaricus in milk is recommended in all 

 diarrhea of birds. Chicks should be fed sour milk as soon as 

 hatched. 



TRICHOMONIASIS 



Trichomoniasis of chicks has recently been described. The 

 baby chicks are attacked at the age of 10 to 14 days. After 

 four weeks old they are immune. Diarrhea may be absent in 

 the early cases but present in later stages and chronic cases. 

 The acute cases die in from one to two days. ]\Iore vigorous 

 birds enter the chronic stage. 



The affected chicks droop, huddle together, do not refuse 

 to eat, wings drag, eyes are closed, heads pale, temperature 

 subnormal, 102° Fah. 



At autopsy there are noted no lesions except an anemic con- 

 dition. The cecum may be 

 slightly enlarged and its 

 contents slimy and the 

 crypts in the mucosa are 

 found to be filled with the 

 Trichomonas puUor'um.

 TION OF THE PIGEON 



There is a condition in

 portion of the esophagus 

 and other parts. It is il- 

 lustrated in Fig 54. The 

 squabs become affected 

 earlv, and a.s the diseased 

 or tumior-like area becomes 

 larger, due to the accunui-

 the bii'd is unable to eat or swallow. The loss in some breed-
