I4 DISEASES OF THE DOMESTIC ANIMALS 



with the various colors on the scale when it is fresh, but after a few 

 minutes for the moist gloss to disappear, or after pressing the stain 

 against a piece of blotting paper. In pernicious anemia, the red 

 corpuscles are much reduced (generally below 1,000,000 per cu. 

 m. m. ) and usually forms, as megalocytes (large corpuscles), 

 microcytes (small corpuscles), poikilocytes (irregularly shaped cor- 

 puscles), and nucleated corpuscles are found. The total hemoglobin 

 is low (10 to 50 per cent.), as shown by the Tallquist color scales. 



Anemia In Sheep (Hydremia). — This condition is often 

 enzootic in flocks from exposure to wet and cold, improper feeding 

 and poor care. Edema of dependent parts, ascites, great weakness, 

 diarrhea, and slow exhaustion and death frequently follow. 



Treatment. — The ordinary form of anemia being secondary, 

 it is incumbent upon us to find and remove the cause, if possible. 

 It is probable that autointoxication from indigestion is one of the 

 most common causes of anemia. For this reason it is well to supply 

 salt liberally to increase gastric secretion, or to give diluted hydro- 

 chloric acid; also to keep the bowels loose with laxatives — as salts 

 on the food or bran mashes for horses. The diet is of great im- 

 portance in supplying iron and available proteids. Thus, for the 

 large animals, the grains, with a pint to a quart of oil meal daily, 

 and milk — to the extent of two or three gallons daily — with a 

 proper amount of coarse fodder are indicated ; while for dogs, milk, 

 meat juice, bovinine (3 i in milk thrice daily) with meat are par- 

 ticularly useful. When the appetite is poor, the bitters are of serv- 

 ice, as fluidextract of nux vomica on the tongue (H., 3 i ; D., TT\. i), 

 which also stimulates peristalsis. Care of the skin by careful 

 grooming and, in the case of horses, clipping in the spring and fall, 

 when the animals are "changing their coats," are of service in 

 averting and benefiting anemia. Well-ventilated quarters and rest 

 conduce to blood formation. The feeding of finely ground bone 



meal to young anemic pigs is of value in supplying calcium phos- 

 phate.
