of live weight. It is best given thoroughly mixed with the food, 

 and should not be given oftener than once a day. 



The results from the use of this remedy have been found to be 

 very good in a number of instances. Sick animals which entirely 

 refuse food will often show a marked improvement in appetite 

 and general condition after one or two doses of this compound. 

 However, it is by no means a curative remedy, and cannot be 

 depended upon to produce any remarkable results. However, in 

 case of an outbreak it is worthy of trial, but should not be used 

 to the exclusion of serum. As far as that goes, serum is by no 

 means to be considered as a curative of cholera, but is more of a 

 preventive. Some cases have apparently recovered after the giv- 

 ing of serum, especially if it was given early, but even the most 

 enthusiastic advocates of the serum treatment do not claim for it 

 any great curative powers. 



As a preventive treatment this combination of hyposulphite 

 of sodium with black antimony cannot be regarded as nearly so 

 effective as the serum immunization, but it is, nevertheless, an 

 excellent condition powder, and will do a great deal to keep your 

 animals in a condition to resist an attack of cholera or any other 

 infection. We must not think, however, that by the administra- 

 tion of such a remedy as this we can relax our efforts in every 

 other direction and disregard all the laws of sanitation and quar- 

 antine. 



SUMMARY 



Briefly summing up the preventive measures which are of 

 value in checking the outbreaks of hog-cholera, we find the follow- 

 ing important facts to be worthy of our serious consideration: 



(1) Breed. — It is a false idea that certain breeds of hogs have 

 any definite immunity to cholera. One breed is as likely to take 

 cholera as another. Avoid too close inbreeding, as this lowers the 

 strength of the animals. Do not place confidence in any single 

 breed as being secure against attack by cholera. If you do, you 

 are bound to be disappointed. 



(2) Feed lots must be kept in a sanitary condition if we are to 

 keep the herd free from cholera. Do not allow the presence of 

 any old, dirty mud-holes for use as hog wallows. Provide a clean, 

 dry place for feeding, and do not make it necessary for the ani-
