Using a 50:50 blend of spray-dried plasma protein (SDPP):spray-dried wheat gluten (WG) (i.e., with each as approximately 4% of the diet) gave the greatest ADG and ADFI, while reducing diet costs compared to the control diet (i.e., 8% SDPP). Even with a slight decrease in efficiency of gain, the marked
decrease in diet cost will yield better cost
of gain with a 50:50 blend versus using only
SDPP.
