Abstract excerpt

BACKGROUND: Reproduction traits constitute the primary objective of porcine genetic improvement programs, with litter size being the principal determinant of herd reproduction output. Relative to the intensively selected Large White line, as a breed derived from Large White (LW) and Beijing Black (BJB) pigs, Jishen Black (JSB) pigs exhibit markedly lower litter size, indicating substantial potential for genetic...
