ISOLATION OF TUBERCULOUS CATTLE BY SEPARATION, 405 
in other barns reserved for the diseased animal is heard re¬ 
peatedly, cannot be heard here either at day or at night. 
And another thing is worth mentioning, that sickness (digest¬ 
ive disarrangement—the keeping back of the afterbirths) to 
which the diseased animals are very susceptible, very seldom 
appear among the healthy cattle. So also the calves, since 
they have been fed on the milk of healthy cows, enjoy much 
better health. Diarrhoea is one of the exceptional causes of 
sickness. 
In review of the experiences made here, I think I can with 
certainty state that by increasing the number of health} 7 , and 
by gradually decreasing the number of diseased animals, es¬ 
pecially, however, by the separation of diseased calves, the 
Kusthof herd will, in a few years, be entirely free from tuber¬ 
culosis. 
In regard to the economical value of a healthy herd to 
the. owner I need not refer. 
The principal advantage to him will be that the milk cows 
can be used as such to a much more advanced age, and can 
then be more easily fattened ; and not, as is often the case with 
tuberculous cows, that, in the best lactative period, they fall 
away and die. Again the milk of such a herd will find much 
readier and more profitable sale in cities and towns, for it 
certainly is to be expected that parents will at last recognize 
of how great importance to the health of their children, not 
only so-called good, but healthy milk is. 
According to my judgment, therefore, the first step in the 
direction of fighting tuberculosis among human beings is the 
restriction of tuberculosis in cattle. The nourishing of human 
beings with the product of tuberculous cows has caused more 
sickness and death than can easily be determined by statistics. 
I hope, therefore, that the example of Hon. Von Sivers, 
to produce a healthy herd, will find recognition and many 
imitators.
