Guanidine hydrochloride soluble intramuscular collagen (GSIC) obtained from purified longissimus intramuscular collagen of five yearling and five older doe antelope and from two lambs and two ewes varied with age but did not differ significantly (P < 0.05) between species. Gel‐disc electrophoresis of denatured GSIC showed a lower percentage of α‐chain and a higher percentage of β‐component for antelope than for sheep. Total collagen content was lower in antelope than in sheep muscle. Therefore, the extreme tenderness in antelope muscle may result from a lack of intramuscular collagen rather than variation in collagen crosslinking.
