Deer research and Invermay

Deer research and Invermay

The history of deer farming research at Invermay goes back to its origins in 1972 when Dr Ken Drew (MAF Research Division) and Les Porter (MAF Animal Health Division) spent three days in Southland and Central Otago visiting people involved with ‘holding deer behind fences’. Their fateful meeting with Herbie Taylor and sons at West Dome Station, near Mossburn, saw them secure 92 borrowed hinds for the start of the Invermay deer project. After much trial and tribulation, these hinds, which were essentially feral, were yarded and trucked to Invermay on 10 October 1973, and 66 calves were born from 30 November onward. A hand-reared stag (Herbie’s pet, whose notoriety for cunning and spite will forever be in the annuls of history) was obtained from West Dome the following year and remained on Invermay as the primary sire stag of a number of years. Upon his demise (which, from all accounts, was eagerly ‘assisted’), his mounted head was gifted to the then Minister of Agriculture, Duncan MacIntyre. The head has since returned to Invermay, where it now menacingly presides over the meetings held in the George Holmes Room. It would be true to say that the first few years proved a testing time for researchers but much was learned about animal and human behaviour. The early years largely focussed on how to take a feral animal and tame it! Thereafter, the name Invermay became synonymous with deer farming research, an institution almost as old as New Zealand deer farming itself. Invermay has been involved in the following research for a more profitable deer industry:
