ELEVENTH ANNUAL YEAR BOOK— PART X 493 



Hog cholera prevails in certain sections of the state from time 

 to time. "We have now established our own serum plant, and are 

 in a position to meet this problem more effectively than we form- 

 erly could. Gratifying results have followed the establishment of 

 this plant, and it is hoped that future difficulties along this line 

 will not equal those of the past. However, cost of maintaining 

 the plant and other expenses connected with this division of our 

 work necessitates an increased allowance, and a larger appropri- 

 ation for this purpose is simply a necessity to the continuation 

 of the work. The hog industry in Iowa is one which has made 

 the state famous throughout the world, and its magnitude fully 

 entitles it to a liberal support from the state to which it contributes 

 such magnificent revenues. A glance at the statistics bearing on 

 the subject is sufficient to enable any one to form some measure- 

 able conception of the size of this industry. In fact, the live 

 stock industry generally is of such vast proportions that it is ab- 

 solutely unjust to fail to throw over it the protection afforded 

 by a well-supported live stock sanitation bureau, such as this 

 department might be made to supply. 



Co-operating with the Bureau of Animal Industry at Washing-

 ative to the locality and extent of stock diseases throughout the 

 entire country. This information is valuable in guarding against 

 infection through the importation of diseased stock, and in pro-

 given the benefit of experiments and observations of government 

 experts in the Department of Agriculture, all of which tends to 

 the betterment of sanitary measures instituted for the protection 

 of live stock in Iowa. 



The State Veterinary Surgeon has responded to calls from gath- 

 erings of stockmen and farmers, Farmers' Institutes and the like, 

 for talks and papers on topics relating to the work of this depart- 

 ment. He has used lantern slides and other materials illustrating 

 specific cases which have come under his observation and treat- 

 ment. However, his official duties have not permitted very ex- 

 tensive labor in this important field. Educational work along 

 these lines is of great importance toward securing that interest 

 and co-operation among farmers and stock growers that is essen- 

 tial in order to make effective the measures which are undertaken 

 from time to time to control and eradicate infectious diseases among 

 live stock. Sanitary measures always depend largely for their
