How long can extended boar semen remain viable?

Extended boar semen can remain viable for 3 to 7 days when stored properly. This viability period allows for successful artificial insemination, as sperm must be capable of fertilizing an egg within a certain timeframe after collection and processing. The extension of boar semen is a common practice in swine production to enhance breeding management and optimize reproductive efficiency. Techniques such as refrigeration are utilized to maintain the sperm's vitality during this period, ensuring a higher chance of successful fertilization.

Other durations mentioned in the options either exceed or do not reach the optimal timeframe for effective boar semen viability. While extended storage may seem feasible, the longevity of sperm's motility and overall health declines significantly after the 7-day mark, making the 3 to 7 days window the most practical and reliable for breeders.
