time or even permanently. The prognosis is particularly un- 

 favorable in old animals and when a proper regulation of the 

 diet is impossible. The prognosis of secondary chronic intes- 

 tinal catarrh depends upon the primary underlying disease. 

 There is no hope of recovery in ''Darrsucht" after cachexia is 

 once present; young animals three to four months old gener- 

 ally succumb to this disease. Chickens affected by infectious 

 astenia generally die. 



Treatment. A rational diet (see pages 295 and 330) offers 

 the best means of preventing the development or to stop the 

 progress of chronic intestinal catarrh. The sick animals should 

 be taken out daily and should be used for work only moderately. 

 Animals attacked by ''Darrsucht" may recover in one to two 

 month if they are pastured, provided that the disease has not 

 progressed too far. 



To regulate defecation, castor oil and the neutral salts are 

 indicated, among the latter particularly Carlsbad salt (for dos- 

 age, etc., see page 331). The desired effect can, however, only be 

 attained if the salts are administered to the animals one-half to 

 one hour before feeding, and in moderate doses (130-500 gm. pro 

 dosi, or of the 5% solution, tablespoonful doses). This course 

 must be continued for a long time and kept up for some time 

 after recovery. With the salts may be combined bitters (gen- 

 tiana, calamus, rheum, oak bark). Constipation must be counter- 

 acted by mild laxatives, diarrhea by astringents and mucilagin- 

 ous medicines (see page 332). Good results have been brought 

 about in horses by the systematic administration of creolin. 



A good result may as a rule be expected only in primary 

 catarrh and while the general condition is still fairly good. The 

 authors again point out the possibility that intestinal worms 

 may be the cause of the trouble ; cases which have been treated 

 for a long time without any success at all, have jdelded in a 

 short time, after an antihelmintic treatment was instituted. 



Against infectious asthenia of chickens, Klee recommends the ad- 

 ministration of castor oil (in teaspoon doses) or of calomel (0.01-0.05 

 gm. ) until a marked laxative effect becomes manifest. The birds ought to 

 rec(}ive further, daily twice per head, 1-2 gm. of the following mixture : 

 Fennel, anise seed, coriander, bark of quinia, each 4 gm.; powdered root 

 of gentian and ginger, each 7.5 gm. ; sulphate of iron 2.0. As drinking 

 water the fowls should have a watery solution of sulphate of iron and 

 sulphuric acid (1000:2:2). The healthy animals must be separated and 

 the coops must be disinfected.
