Many dairymen use “sexed” semen to insure an
adequate replacement supply given fast cow turnover rates in their herds. “Cow turnover” gets blamed on lots of
things, but—
And common sense will tell you this is true—the
biggest fault may be our random use of aggressive genetic selection at least
without proper compensatory mating to balance it.
If you are using sexed semen, we sell the ST
Genetics program, which is owned by the company that controls the
patent on the sexing process. The
benefit of their years of research in perfecting the sexing process and semen
recovery is available in their sires.
If you would prefer not to use sexed semen, but wish
to insure adequate replacements, consider utilizing the “aAa” breeding
guide as your mating program—the herds with the most longevity at competitive
production levels tend to be “aAa” users, and usually have a surplus of heifers
from normal reproduction.
