rich in starches must be forbidden. Very light exercise 

 in conjunction with the starvation gives better results 

 than complete rest or idleness. 



LUPINOSIS 



Lupinosis occurs in sections where alfalfa is fed on 

 pasture. The disease is quite common in the northwest- 

 ern states. It results from the ingestion of lupine 

 grasses containing lupinotoxin. 



Symptoms. While there may be an initial constipa- 

 tion, as claimed by some writers, the first symptom in 

 my cases has always been violent purgation. The evacu- 

 ations occur very frequently and at last are wholly fluid. 

 This purgation may continue for several days, at the end 

 of which time the horse appears greatly emaciated. There 

 is now a wabbly gait, lack of coordination behind, and 

 the horse stands about listlessly. The eye has a peculiar, 

 bright, glassy stare. When the disease has been in ex- 

 istence for three or four days the buccal mucous mem- 

 brane becomes the seat of irregular ulcerated areas, vary- 

 ing in size from that of a pea to a twenty-five cent piece. 

 They have a tendency to spread and enlarge, and stub- 

 bornly resist ordinary treatment. The horse retains 

 some appetite throughout, but may not begin to eat nor- 

 mally as long as the mouth is the seat of extensive ulcer- 

 ated areas. The animals consume immense quantities of 

 water if permitted to do so. In some cases there are also 

 ulcerated areas on the skin of the lips, head or neck. 



In most cases edematous swellings appear in various 

 parts of the body. The case may terminate in death in 

 from a week to two weeks, during which time the purga- 

 tion continues, and at the end of which time the horse is 

 in a pitiable state of emaciation. Cases may recover
