Until mid-1957 most dairymen were expanding their herds. Many old
animals were kept that were difficult to breed. When a military market
failed to materialize in 1957, many of these unsatisfactory cows were the
first to be culled. This culling accounts in part for the improvement in
conception rates beginning in late 1957. Other contributing factors were
better communications and roads, possibly better insemination skills, and
more important the economic squeeze that forced operators to watch more
carefully for heat periods.

This has been a good year in getting cows with calf. Begining in April, 1958,
89.6 per cent of all cows conceived on the first two services. This is an exceptionally good rate . Only 99 cows needed servicing four times or more—8.4 per cent
of the total. This is lower than average far several years, and is lower than in
many breeding associations in the other States.

In 1957 the conception rate has run about the same as in past years, except
that August was the lowest month for the year. The figures show that 81% of
the cows conceived on their first two services and nearly 92% on their first
three services. Only 97 cows out of 1,177 required more than three services.
This is about the percentage would would be expected. Usually some of these
difficult cows will get with calf and some of them never will.
