Discuss briefly the etiology and prevention of haemoglobinuria. 



Hagmoglobinuria (azoturia) occurs almost iuvariably in well- 

 conditioned, plethoric horses, accustomed to regular work, after 

 a day of idleness without reduction in the amount of rations. It 

 is rarely seen in poorly nourished horses. Cold is thought to be an 

 etiological factor as more cases are seen in winter than in summ.er. 

 It is probably aa auto-intoxication, the exact nature of which is 

 undetermined. 



Prevention: Give regular exercise and reduce rations when 

 idle.

 be present ; the muscles of the gluteal region are hard and swollen ; 

 urine is coffee-colored or black ; pulse full and accelerated, tempera- 

 ture normal or slightly elevated. 



Treatment: Nothing specific. Quick-acting cathartics such as 

 arecoUne and Epsom salts ; hot blankets over the loins may help ; 

 evacuate the bladder regularly; plenty of bedding should be pro- 

 vided and the patient should be turned over every 4 to 6 hours. 

 Bromides or chloral hydrate may be given per os, or cannabis 

 indica, intravenously if the patient is restless. Slings are used by 

 some but should not be used unless the patient can stand well, in 

 which case they are needless.
