Milk was obtained from five Rocky Mountain bighorn sheep living in the Jasper Park area of Alberta. The milk was collected at [Formula: see text] and 3 months post partum. The gross composition and milk fat fatty acids of the milk samples and of a sample of domestic sheep milk (Suffolk, 1 month post partum) were determined.

On lactation and rumination in bighorn ewes ( Ovis canadensis )
Journal of Zoology, 2005Because lactation has high energetic costs, females should vary their foraging behaviour according to reproductive status. In ungulates, however, some studies found no differences in feeding behaviour between non-reproductive (yeld) and lactating females.

Play frequencies in captive and free‐ranging bighorn lambs (Ovis canadensis canadensis)
Zoo Biology, 1987AbstractBehavioral observations on captive animals are frequently extrapolated to provide species‐typical descriptions of a given behavior. Comparative studies of free‐ranging and captive animals are critical to substantiate this practice. We compared play frequencies in two populations of bighorn sheep (Ovis canadensis canadensis).

Occurence of Upper Canines in Mountain Sheep, Ovis canadensis
American Midland Naturalist, 1943Discovery of upper canines or their alveoli in three specimens of mountain sheep led me to search for records of these teeth in sheep and their relatives. Most references concerning the teeth of the Bovidae (antelope, sheep, and cattle) state that upper canines are absent. Actually, exceptions to this rule have been recorded, but they are few.
