Plasmin activity in whey (A) and casein (B) fraction of ruminant milk (bovine, ovine, and caprine) unheated (raw) and heated (63°C/30 min and 85°C/5 min). There was a significant effect (P < 0.001) for all main factors (species, treatments, and fractions) and all their interactions. Values are means ± SEs, n = 3. Means with different letters across species (bovine, ovine, and caprine) within raw milk for each fraction differ significantly (P < 0.001). Lines with an asterisk represent significant differences (P < 0.05) between treatments (raw, 63°C/30 min and 85°C/5 min) within each species. For raw caprine and raw and heated at 63°C/30 min bovine and ovine milk, there were differences between the whey and casein fraction (P < 0.001).
