of them did not retain the placenta. One cow was elimi- 
nated without treatment, and twelve became pregnant, six 
of which had a normal estrum. One animal aborted for a 
second time. 
5. In the herd of Mr. D., St. Myregaard, 17 cows out of 
30 aborted between July 1907 and May 1908, 14 became 
pregnant again, two of which aborted for a second time. 
Three animals were discarded, one during the treatment. 
6. In the year 1907 14 cows out of 34 on the estate 
Eskildsgaard aborted. Ten became pregnant again, none 
of which aborted for a second time. Four cows were dis- 
carded, three of them without treatment. 
7. During the year 1907, 13 cows out of 35 aborted in 
the herd of Mr. O. T., Ventegodgaard. Twelve conceived 
again; one was affected with a pyometra. 
The following tabulation indicates clearly that the milk- 
production need not suffer in the year of the abortions; 
whether or not it is deficient in the following year depends 
on the time which was needed to cure the prevailing metritis 
cases. The milk-production, in other words, depends on 
whether the aborting animals conceive again in due time and 
carry out in the second year.
