"Wapiti Behind Wire" by David Yerex
Its not a recent book,but it tells the story of these large red deer in NZ & how they were utilised in the deer farming industry.The health & feed issues are still pretty current even though the book would be over 20 years old now.
I bought my copy way back when,but I think the Australian Deer Industry Association book shop may still have copies avaliable.
