Transport-related influences on the quality of liquid-preserved boar sperm: A review.

This review explores the impact of transport-related stresses on the quality of liquid-preserved artificial insemination (AI) doses in pig reproduction. Transport of boar semen from AI centers to sow farms, the place of application, is an essential part of the production chain with increasing international demand, especially against the background of growing export demand. Understanding how factors such as: a) transport-related vibration emissions; b) temperature fluctuations during transport; c) transport duration; d) duration of storage after transport; and e) the method used for preserving AI doses, affect their quality is, therefore, essential for optimizing fertility outcomes. We provide a review of existing literature on the biological responses of liquid-preserved boar sperm to transport conditions. In addition, we discuss their impact on sperm quality and summarize potential mitigation strategies.
