This study evaluated the effects of globin and spray-dried porcine plasma on growth performance, digestibility, nitrogen retention, energy retention efficiency and intestinal morphology of broiler chickens. A total of 336-day-old male broiler chickens were reared from 1to 40 days of age and fed 3 diets during 3 feeding phases: starter, grower and finisher. Isonitrogenous diets were formulated by replacing gluten protein isolate contained in the control diet with 2% or 1% spray-dried porcine plasma in the plasma diet . … Overall, these results confirm that dietary supplementation with SDPP and, to a lesser extent, with globin can improve growth performance and dietary protein and energy utilization in broiler chickens without effect on gut functionality.
