Effects of mechanical lead system for boar control during heat detection on libido and salivary androstenone

摘要

Daily boar exposure for weaned sows shortens weaning-to-estrus interval.613 Boar libido impacts a technician's ability to correctly identify heat.6 Mechanical leads are used for human safety and to reduce labor for boar movement and heat detection. Todate, we are unware of other studies that have measured impact of mechanical lead on libido and salivary androstenone level. This study compared two options for mechanical leads, the Boar Bot (BB) and Contact-O-Max (CM) on measures of boar libido during heat detection and effects on salivary androstenone as a potential indicator for libido.
