Dr. Diaz: What was Pollans purpose for introuducing Steer 534?

I think that the purpose for introducing Steer 534 was to inform us about the cows background. The text states, "Steer number 534 spent his first six months in these pastures alongside his mother..." This shows that the author is informing us about the cows background. Also the text states," Born on March 13,2001/ adding his diet of mothers milk..." This also shows that its informing the reader.
