For this study, frozen tails of mature cows were obtained from a local slaughterhouse. The tails have 6-9 discs which are similar in size to human spinal discs. The discs were removed from the tail, thawed, dissected, and tested the same day. There was no added liquid, re-freezing, etc. Dynamic oscillatory compression tests were performed on the cow (bovine) spinal discs and compared to previously published human data.
