From the first day to the age of eight years and a half, post-natal development of spinal column was studied in 84 sheep of the Merino breed and 40 crossbred goats. At birth time the axial skeleton was observed to have a high degree of development. Coalescence of the components of spinal column segments starts soon after birth and generally terminates by the third year of life. In animals above three years of age ossification or calcification centres occur in the cartilaginous margin of the spinal process of the second cervical vertebra and in lig. supraspinale . The heads of all ribs and processes ( extremitates ) of the last caudal vertebrae also ossify after birth. The time of the coalescence of the components of vertebrae is about the same in sheep and goats; in some sections it may be even earlier or later in the goat than in sheep. No sexual dimorphism was observed in the coalescence of the components of vertebrae in small ruminants.
从出生第一天到8岁半，对84只美利奴品种绵羊和40只杂交山羊的脊柱产后发育情况进行了研究。出生时观察到轴骨骼发育程度很高。脊柱节段各组成部分的融合在出生后不久开始，一般在生命的第三年结束。在三岁以上的动物中，第二颈椎棘突的软骨边缘和棘上韧带出现骨化或钙化中心。所有肋骨的头部和最后尾椎的突起（末端）在出生后也会骨化。绵羊和山羊椎骨各组成部分的融合时间大致相同；在某些部位，山羊的融合时间可能比绵羊更早或更晚。在小型反刍动物椎骨各组成部分的融合过程中未观察到性别差异。
