Trials were conducted 3 times during the 1992 growing season. Activity budgets were calculated using scan sampling. Hand-harvested simulated bites were weighed to determine bite size, and bite rate was calculated using focal sampling techniques. Intake was calculated as a function of bite size, bite rate, and time spent foraging. Digestive physiology of mukoxen may have favored higher intake of a mixed grass-browse diet over grass alone.
Previous data suggest that elevated intake increases weight gain and qiviut growth.
