Plant growth regulators don't affect fertility
Research results from the University of Aarhus have revealed that plant
growth regulators in pig feed have no adverse effect on pig fertility.
New results from the Faculty of Agricultural Sciences (DJF) at the university
reveal no adverse effects on sow or boar fertility. The experiment was carried
out in collaboration with Copenhagen University Hospital and the Technical
University of Denmark.CCC
"We have not been able to
confirm the common conjecture that the plant growth regulator chlormequat, also
called CCC, has a detrimental effect on pig reproduction," explains senior
scientist Martin Tang SÃ¸rensen from the Department of Health, Welfare and
Nutrition at DJF.
The study included both boars and sows. The boars
were exposed to CCC throughout their lives including the foetal stage, as their
mothers were given CCC-enriched feed from the day they were
After weaning, the boars continued
receiving CCC in their feed until the end of the experiment. The intake of CCC
by the animals was at the maximum permitted level for humans.
was no sign of boar semen quality having deteriorated in terms of either sperm
count, sperm activity or the ability of the sperm to fertilise compared with the
sperm from boars in a control group.
Neither could scientists
establish any adverse effects of CCC on sows.Related
