INDIGESTION OF THE FOURTH STOMACH IN 

 THE YOUNG. 



Causes : Symptoms : Dullness, recumbency, inappetence, colic, acid 

 eructations, abdominal tension, costiveness, diarrhoea, emaciation. Lesions: 

 Sour coagula in stomach, puffy or congested nmcosa, undigested casein in 

 bowels and faeces. Prevention as in infector gastro enteritis. Treatment : 

 Elimination, antacid, antiseptic, carminative, stimulant, rennet. 



While the fotirth stomach in the inattire animal is protected 

 against danger b}- the preparatory work of the fir.st three, and by 

 their action in retarding the food in it.sprogre.ss, and allowing it to 

 pa.ss into the fourth onl}- when thoroughly comminuted and then 

 only in .small quantity at a time; in thesuckling on the other hand 

 the milk pas.se.s at once into the abomasum, which is thus ren- 

 dered as su.sceptible as in the monogastric animal. 



Causes. The causes are almo.st identical with those set forth 

 under infective oastro-enteritis of the suckling, acting however 

 with less force, or on a less susceptible system. Overloading and 

 the restilting paresis ; unsttitable milk from another genus, or 

 from unhealthy, over- worked, or over-fed specimens of the same 

 gentis ; the ingestion of hard, insoluble, indigestible or toxic 

 aliments, and exposure to cold and wet are among the mo.st com- 

 mon direct cau.ses. As secondary causes are over- feeding of the 

 cows, and bringing up the calves on the pail with all kinds of 

 substitutes for the milk of the mother. 



Syuiptouis. Dullness, lack of sportiveness and of appetite. 

 The patient lies down a good deal, but is nervous or restless, and 

 when up shows colicy pains by movements of the tail and hind 

 limbs. He may moan gently or bellow frequentl_v. The muzzle 

 is dry, the mouth clammy, hot and sour, the abdominal mu.scles 

 rigid and the bell}- often somewhat swollen, and resonant on 

 percussion. Acid eructations are common. At first there is 

 costiveness, but in a few hours diarrhoea sets in and usually proves 

 critical, clearing away the offensive and irritant materials and 

 paving the way for recovery. The tension of the belly lessens, 

 by degrees, the appetite returns, the bowels resume their normal 

 tone and in twentj^-four or fort3'-eight hours health may be fully 

 re.stored.
