White-tailed deer farming has emerged as a profitable industry in the US, with over 4,000 operations generating sales of almost $44 million in 2012. This industry, predominantly located in Texas, Pennsylvania, Ohio, Michigan, and Minnesota, raises deer for meat, antlers, hides, urine, and provides hunting experiences. It is important for would-be farmers to investigate market demand and understand the differences between white-tailed deer and other species farmed in New Zealand and the UK. The industry is divided into breeding and hunting ranches, with a requirement for specific land, water, and animal handling facilities. Deer require specialized care, including handling, transportation, and nutrition, and are susceptible to parasitic, bacterial, viral, and fungal diseases. Farmers must also consider financial and insurance aspects, including start-up capital and livestock budgets.
