Functional properties of spray-dried animal plasma in canned petfood

The addition of plasma contributed to enhancing the palatability, particularly in cats, over the standard diet in which it replaced wheat gluten. The total intake in cats after 2 consecutive days comparing loaf containing SDAP or WG at the same inclusion (20 g/kg) was statistically improved with the inclusion of SDAP (141 and 78 g, P < 0.001). Similar results were obtained for first choice and in another study comparing loaf containing SDAP at 10 g/kg or WG at 30 g/kg (total intake 151 and 61 g, P < 0.001, respectively).
