| Abstract: | Multi vertebral trait has been reported in mouse, swine, sheep and poultry, and the increase of vertebral numbers would increase the meat product of animals. In current survey, we investigated the vertebral numbers, including thoracic vertebral （T） and lumbar vertebrae （L） in 2070 Qinchuan cattle. Five different thoracic and lumbar combinations of T14L6, T14L5, T13LT, T13L5 and T12L7 were found, in which T14L6 and T13L7 belonged to multi-vertebral trait in cattle. T14L6 accounted for 61 cattle and T13L7 for 51 cattle, with a frequency of 5.41%. This survey provides a potential direction for cattle breed- ing in high meat production. |
