certainly appears to be made up of healthy animals, and the farm
inspector has expressed the decided opinion that the tuberculosis in this
division is no more developed than at the beginning of the experiment.
The testimony of many owners of large herds of cattle which have long ago
been injected is to the same effect. I will adduce statements from
several. A farm tenant whose cattle were injected 20 months previously,
when 82 per cent of the grown animals reacted, wrote me recently as
follows: "Only 2 cows from the division of 100 head had been sold as
decidedly tuberculous. The majority appeared afterwards, just as before,
entirely healthy. The fat animals which had been slaughtered had been
pronounced healthy by the butchers." Another farm tenant with a herd
injected in 1894 had not been obliged to remove a single animal from the
tuberculosis division, numbering 70 head. A large farm owner in Jutland
stated in September that he had traced no undesirable result from the
injection. His herd of 350 had been injected in February and about 75 per
cent reacted. Similar answers have been given by other owners and
veterinarians.
A veterinarian who had injected 600 animals, among them a herd of a large
farm, 18 months previously, expressed the belief that the injection had
produced in no single case an unusually rapid or vicious course of
tuberculosis. In spite of a demand made months ago, I have received thus
far no report from any veterinarian of an undesirable result.
On a large farm, on which before the injection tuberculosis had appeared
in a vicious form, the owner had the impression that the severe cases had
afterwards become more numerous. He had, however, not suffered severe
losses, and 8 months later the large reacting division by no means made a
bad impression. Finally, it is to be noticed that tuberculin has been
employed on a large scale in Denmark for years, and still the demand from
farmers constantly increases. This could certainly not be the case if the
injections were generally followed by bad results.
Paige said, after the tests of the herd of the Massachusetts Agricultural
College, that "its use is not followed by any ill effects of a serious or
permanent nature."
Lamson, of the New Hampshire College Agricultural Experiment Station, said:
"There is abundant testimony that its use is not in any way injurious to a
healthy animal."
