.ItropJw or H'asliii;/ of the Li:\'i'. 



This is vcMv siniilai- in many respects to the disease described 

 hv Salmon as fatty degeneration and probably arises from the 

 same cause, ;'. c, lack of variety in the food, especially lack of 

 green food. 



Symptoms. — Robinson sa.ys: "There are no special external 

 svm]itoms. An examination of the fowl after death shows the 

 liver shrunken and somewhat granular and sometimes of a 

 yellowish cast." 



Treatment. — See Salmon's treatment of fatty degeneration 

 above. The ilock should be given frequent (weekly) doses of 

 Epsom salts. 



Coiif/esfion and J nflauunation of the Liver. 



These are prol)al)ly different stages of the same disease. The 

 poultrvman will fnid difficulty in distinguishing between this dis- 

 ease and that known as hypertrophy of the liver (cf. p. 50). 

 The chief jiost-mortem dift'erence is that in the latter disease 

 the liver is more solid, not so easily torn or ruptured. 



Diac/nosis. — There are no external symptoms other than those 

 of dullness and the general symptoms of disease. Salmon says: 

 "It is difficult to make a diagnosis during the life of the bird. 

 Post-mortem examination reveals a greatly enlarged liver en- 

 gorged with blood, tender and easily torn or cruslied." 



Treatment. — Treatment of these diseases in individual birds 

 is very rarely successful. The general treatment of the flock as 

 recommended on p. 49 should be attended to. The chief medi- 

 cinal treatment should probably be frequent doses of Epsom 

 salts. \'arious authors recommend different medicinal treat- 

 ments. For these see Robinson (pp. 71 to 74). 



Jaiindice. 



jaundice <^r biliar}- rei)letion is said by Megnin (Medicine des 

 Oiseaux ) to be due to long continued but moderate congestion 

 of the liver. Tliis leads to increased activity of this organ and 

 is followed 1)\- the accumulation of a large quantity of bile in 

 the gall bladder and ducts of the bird. This bile is ab.sorbed by 

 the blood vessels and cau-^es poisoning which may lead to the 

 death of the bird. 



Diagnosis. — Tliere are no specific external symptoms other
