PREVENTION, SYMPTOMS AND TREATMENT j,j 



vomica may be given thrice daily; salts and linseed oil, once or 

 twice daily ; and sloppy food, as bran mash with linseed tea. Gas- 

 trotomy is indicated in such cases, when they do not yield to medical 

 treatment, except in old cows and those with a high temperature 

 (Moussu), but not more than two-thirds of the contents of the 

 rumen should be removed. This operation is also demanded in the 

 acute cases of impaction of the rumen with serious tympany. 



Impaction of Omasum or Third Stomach in Cattle, More Barely in 

 Sheep or Goats — Dry Murrain — Fardel Bound — Stomach or 

 Grass Staggers. 



The causes are very similar to impaction of the rumen, i. e., 

 dry fodder without sufficient water; sudden change from dry to 

 green food with fermentation, toxemia, inhibition of movements 

 of the stomach, dilirium and convulsions. The first three stomachs 

 do not secrete fluids and are dependent on saliva and ingested 

 liquids. Hence febrile diseases inhibit salivary secretion and cause 

 the food to become dry and caked in the folds of the third stomach. 

 Impaction of the omasum is also one of the results of lead poisoning. 



Symptoms. — There are differing degrees of severity depend- 

 ent upon the cause. Three types are noted by Moussu. There is 

 that following fever or inflammation with loss of rumination, 

 slight tympanites, and unusual resistance over the rumen and 

 omasum. Other digestive disturbances include constipation, with 

 feces streaked with mucus and blood, alternating with diarrhea. 

 Malnutrition is indicated by cold extremities and rough coat. The 

 disease may drag on indefinitely with gradual decline. When the 

 condition is more marked the animal is down, lying on the left side 

 with its nose in the right flank. The breathing is quickened and 

 there is a grunting expiration but no signs of lung lesions. On the 

 other hand, the appetite is poor, rumination impaired or lost, consti- 

 pation alternating with diarrhea and the symptoms noted above 

 referring to the digestive organs, especially the feeling of resistance
