| 摘 要： | 该文研究了甘肃瘦肉型新品系猪的乳头数在不同世代、不同胎次中的分布及频率,发现乳头数基本呈现正态分布,在一定取值范围内表现连续变异,因此可断定乳头数是受多基因控制的数量性状。同时对乳头数的遗传力及乳头数与其它繁殖性状的遗传相关、表型相关进行了估测,结果与大多数文献报道一致。

| Abstract: | The distribution and frequency of mammilla numbers were studied in the new lean -meat -type pig lines in the different generations and times of fetus The results showed that the mammilla numbers are in the nomal distribution primarily and presents a continuous variation in a certain range of sampling. From this, it is concluded that the mammilla numbers are a quantitative character controlled by ploygene. In addition, the heritabiiity of mammilla numbers, with other repodutive characters were estimated simultaneously and the results showed no difference with relevant literature. |
