Methods and Key Points for Selecting Replacement Breeding Boars

    When selecting replacement breeding boars, first, choose improved foreign breeds such as Large White, Landrace, and Duroc. Second, the breed must be pure. Third, the appearance must have the characteristics of the breed. A long body and strong limbs, broad shoulders and a wide back with a round rump, evenly sized testicles and a robust body, and at least 6 pairs of teats. The folk saying goes: a pair of bright eyes, full of vitality and showing a masculine look; a small head, wide forehead, and short face, a well-developed front chest and a round rump; a belly that is not large is the look of a boar, the two testicles are both rather long, and when it sees a sow its sexual desire is strong.
