Offered Papers Theme A: Efficient Production from Grassland
Description
Body temperature (BT) measurements are traditionally used in diagnosing sick animals, but may also be used as an indicator of stress or activity. Based on results of metabolism studies, Mader et al. (1999) reported that BT can vary as much as 0.9oC and can depend on metabolisable energy (ME) of the diet consumed. Acceptable measures of BT can be obtained from the rectum, vagina, or ear canal. Technologies are also being developed for continuously monitoring BT via radio-telemetry. The objectives of this study were to determine the effect of high concentrate (low fibre) versus high fibre diets on BT, assess the capabilities of obtaining BT in free-roaming cattle, and compare temperatures taken in the rumen with vaginal and tympanic temperatures.
