【摘要】 本试验观察了不同日龄哈尔滨白猪和东北民猪跟骨骨骺骨化中心及骨骺线的X线解剖学特征。东北民猪出生一日龄跟骨无骨骺骨化中心,而哈尔滨白猪出生一日龄跟骨骨骺骨化中就已存在。一月龄两品种间跟骨骨骺骨化中心面积和骨骺线长度差异显著(P<0.01);而二月龄后两品种间差异则不显著(P>0.1)。更多还原

【Abstract】 The results of this exPeriment showed some characteristics of the radiogra phic anatomy on the epiphyseal ossification center and epiphyseal line of fibular tarsal bone in the Northeast Native and Harbin White pigs at different ages. The epiphyseal ossification center does not appeared at 1 day birth in the Northeast Native pigs, but it does at 1 day birth in the Harbin White pigs. The area of the epiphyseal ossification center of fibular tarsal bone and the length of epiphyseal line were significantly different (P<0.01),at 1 month age, but there had been no difference between them at the 2 month age(P>0.1).更多还原
