• 繁殖力

  Breeders were selected with total breeding value for two lines,high prolificacy,and fast growth and high lean. After selecting three generations,both lines have body figure of typical Tibet pig.

  采用综合育种值对基础群藏猪按照高繁殖力和快生长高瘦肉率2个方向进行选种。

• 多产性

  The effects of combined genotypes of PRL and PRLR have no obvious law. Its genetic effects on prolificacy are not simply the multiplications of every genotype.6.

  5．PRL、PRLR合并基因型对多产性的影响无明显规律存在，其对多产性的遗传效应不是各个基因型效应的简单相加。

• 多胎

  The estimates of repeatability for litter size, lamb survival, fertility, pregnancy maintenance, prolificacy and birth weight were 0.320, 0.435, 0.208, 0.476, 0.410 and 0.426 respectively.

  产羔数、活羔数、受精力、妊娠维持、多胎性和初生重的重复力估值分别为0.320、0.435、0.208、0.476、0.410 和0.426。
