Well, Silver just states [horse and cattle vertebrae] "bodies fuse with epiphyses at 5 years" (p.285), and the lack of detail and lack of source makes me a bit wary about using Silver. 

Habermehl (1975, 99-102) is more detailed on vertebral fusion, and yesterday I tried to translate his (potentially a bit out of date) terminology. Luckily my google skills were better today. Habermehl quotes Keusch and Grätz (1955), saying that at 1-6 years of age the endplates are unfused to fusing. At 7 years the fusion line disappears first at the lumbar vertebrae and at 9 years at latest all endplates are fully fused to the vertebrae. (p.101-102). On the other hand, Schriener (1966) could not find anything for age estimation in his study of Fränkischen Vleckvieh (p.102), so I guess there is some inter-breed variation going on.

My memory is that Silver includes this in his 1969 summary. It is a classic.

I have from a single Iron Age pit at least four articulated spines (atlas - sacrum) in various stage of fusion* and I would like to age them better than "sub-adult - adult".
