How long is chilled semen generally viable once inseminated? We have a mare which was inseminated by the vet but didn't ovulate until 36hrs after insemination with chilled semen... I am worried that the vet has missed estimating when the mare would ovulate and that since she ovulated 36hrs post insemination that the semen would not have been viable by the time she ovulated... Apparently the chilled semen was of very good quality but is that still too long to miscalculate the time of ovulation by?...
It will be stallion-variable, preparation-variable, and also depend upon how long after collection the semen was inseminated.
Some stallions have cooled semen that may remain viable for up to 6 days after collection, others have sperm that are all dead 6 hours after collection.
Correct (or incorrect) collection techniques and preparation of the semen for shipment can have a huge impact on viability.
Bottom line? There is no specific answer to your question, but you'll know in about 14 days when the mare is ultrasounded for a pregnancy check!
