Dissolve these in three pints hot water and use the solution 

 as a drench; repeat in 16 hours if bowels do not move freely. 



Prognosis. — A large percentage of cases recover if properly 

 treated soon after disease appears. Death occurs from asphyxia, 

 rupture of the paunch, or rupture of the diaphragm. 



Prevention. — Hoven is likely to be quickly fatal to sheep; 

 hence, sheep should be closely watched, when they are first put 

 on dangerous feed like green clover, rape or alfalfa. A large 

 proportion of these cases may be prevented, but some will ap- 

 pear occasionally under conditions which cannot be prevented. 

 There are two reasonably safe methods of turning cattle and 

 sheep on new pasture at any season; from a poor to a richer 

 pasture; or from grass to clover. First, feed heavily and then 

 turn them on the new pasture for a few minutes the first day, 

 and increase this time a little each day for a week. Or second, 

 give the cattle or sheep a large ration of the dry food to which 

 they have been accustomed, for several days before they are to 

 be turned on the new feed; feed later than usual on the last 

 morning and then turn them out as soon as they are done eat- 

 ing, which should be after the dew is off the grass and not soon 

 after a rain. Under these conditions, cattle and sheep usually 

 may be turned on grass in the spring or put on new or dif- 

 ferent pasture and left there with little risk. 



Pastures where the old grass stands quite heavy, and the 

 young grass has grown up in it, are much less dangerous than 

 those where the stock gets only the new grass. When cattle or 

 sheep are once safely on a rank pasture, or clover, alfalfa, etc., 

 the more continuously they can be left there, the safer they are.
