The ultimate pH value of meat (measured at approx. 24 hours post slaughter) gives information about the technological quality, i.e. shelf life, colour, water-holding properties and tenderness and is a direct consequence of muscle glycogen (energy) le

This study investigated the utility of GPS data for assigning individual calving dates and times for red deer hinds based on already known generalised movement patterns around parturition. Nineteen hinds expected to calve in early November were fitte

Considerable expansion of red deer farming has occurred in the South Island high country of New Zealand. On these farms, breeding hinds are usually continuously grazed (set-stocked) at low population densities in large highly modified native-tussock

Multiparous red deer (Cervus elaphus scoticus) hinds (n=17) were either mated to a red deer stag or artificially inseminated with semen from a wapiti bull (C.e. nelsoni) to produce red deer or F1 crossbred (C.e. scoticus × C.e. nelsoni) calves to te

a b s t r a c t Land use change and the expansion of dairying are perceived as the cause of poor water quality in the 1881 km 2 Pomahaka catchment in Otago, New Zealand. A study was conducted to determine the long- term trend at four sites, and curre

The largest source of nitrous oxide (N2O) in New Zealand is excreta deposited by farmed, grazing ruminants. A country-specific excreta N2O emission factor (EF3PRP) of 1% is used to estimate these emissions. The aim of this study was to assess if disa
