How to quickly identify successful conception in sows? Practical tips for novice farmers
If you can determine early that a sow has conceived, you can take corresponding measures and management to avoid accidents. If she is not pregnant, strictly prompt the sow to come into heat and mate again to prevent her from becoming an empty sow. This requires understanding just what counts as successful conception in a sow, and many novice farmers do not know
1. Early diagnosis
In appearance, if the coat color is glossy, the eyes are bright and spirited, and the cleft of the lower commissure of the vulva contracts upward to form a line, it indicates conception.

3-4 days after mating, gently pinch the last two pairs of teats by hand. If a relatively hard milk duct is found, it indicates conception.
