154 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 



To a fraction of 1 per cent, if properly applied. (Dr. C. J. Marshall, Uni- 

 .versity of Pennsylvania, Philadelphia, Pa.) 



To show presence of first infection. (Health officer Scranton, Pa.) 



QUESTION 3. What effect in your judgment would its enforcement have on the 



price of cattle f 



ANSWERS. 



The prices of cows, as well as prices of other things, have increased all over 

 the country within recent years, regardless of whether or not the tuberculin 

 test has been applied. The statistics of the Department of Agriculture show 

 that the average value of milch cows on January 1, 1908, was $30.67 per head, 

 while the average value on January 1, 1910, was $35.79 per head, an increase 

 of 16.7 per cent in two years. While it is possible that the price of cows 

 might be affected if the tuberculin test were applied simultaneously over a 

 large part of the country and all reacting animals slaughtered, it is believed that 

 the gradual application of the test, followed by slaughter, carried out in a 

 small area, would have no perceptible effect upon prices. As the milk of 

 tuberculous cows is unquestionably dangerous to human health and life, a 

 slight increase in the price of cows and in the cost of milk should certainly 

 not be considered as an adequate reason for refusing to take steps to remove 

 this danger. Cows affected with tuberculosis are usually not as productive 

 as healthy cows, and their value as milk producers would probably steadily 

 decrease, hence the removal of cows of this class would not be as great a loss 

 as might appear at first. (Chief Bureau of Animal Industry.) 



Ultimately little or none. (Surgeon General U. S. Army.) 



It would undoubtedly raise it. (Surgeon General U. S. Navy.) 



Enforcement of the tuberculin test would probably increase temporarily the 

 price of healthy dairy cows. (Surgeon General Public Health and Marine- 

 Hospital Service.) 



I would at first separate the reacting cattle when in sufficient numbers to be 

 practicable, and use their milk pasteurized. This would lessen effect on price. 

 (Dr. William H. Park, New York, N. Y.) 



Its enforcement would increase the price of cattle from 25 to 50 per cent. 

 (Dr. Henry L. Coit, Newark, N. J.) 



Little or none. (Dr. R. G. Freeman, New York, N. Y.) 



Not able to answer. A healthy cow is worth more than a sick one. Event- 

 ually no effect should be produced. (Dr. M. P. Ravenel, Madison, Wis.) 



Have not statistics. (Dr. T. A. Geddes, Kensington, Md.) 



Slight increase. (Health officer Ann Arbor, Mich.) 



I do not know. (Health officer Baltimore, Md.) 



Locally tuberculous-free cows are estimated to be worth from $2 to $5 more 

 than cows that have not successfully passed the test. (Health officer Birming- 

 ham, Ala.) 



No appreciable effect. (Health officer Bismarck, N. Dak.) 



Would depend upon degree and rapidity of enforcement; probably raise the 

 price of tuberculin-tested cattle materially. (Health officer Cleveland, Ohio.) 



Increased valuation. (Health officer Columbus, Ohio.) 



Temporary rise. (Health officer Detroit, Mich.) 



The immediate effect would be to raise the price, but the remote effect would 

 be to conserve the health and vitality of the cattle and consequently reduce 

 the price. (State board of health Florida.) 



None at all here, as it is done without cost to the dairyman, and few diseased 

 cows are found in this locality. (Health officer Jacksonville, Fla.) 



This question is not specific. Do you mean milk cows; if so, yes. (Health 

 officer Kansas City, Mo.) 



Very little. (Health officer Lynchburg, Va.) 



Have no experience, but would judge that price of known sound cattle would 

 be higher than of possibly diseased cattle. Ultimate price in a few years ought 

 to be as low as at present if tuberculosis is eradicated. (Health officer Mont- 

 clair, N. J.) 



Temporary increase, but later will not affect except that the buyer of milk 

 cows would feel safe in his investment. (Health officer Portland, Oreg.) 



At first might increase price. (Health officer Providence, R. I.)
