agent. Federal law does not require that this product be

HEIFERPLUS is spermagenic
agent for sexing bull semen. Packaged in kit form, each
dose is sealed in a vial to maintain potency during
storage. The agent is activated by adding semen directly
to the HEIFERPLUS vial. The sexed semen is returned to
the original straw and inseminated as usual .
MODE OF ACTION
HEIFERPLUS works by enhancing
the fertility of the X-chromosome bearing (female) sperm
and slowing the motility of the Y-chromosome bearing
(male) sperm. When
inseminated, the sperm sort in
the reproductive tract of the dam. The result is more
ova fertilized by the X-chromosome bearing (female)
sperm. The heifer sex ratio is increased by 20-25% and
fertility is boosted 5-20%.
