Pellet processing of diets containi

Pellet processing of diets containing high quality animal
protein sources such as whey protein concentrate, fish meal
and spray-dried plasma protein would be better than
extruder or expander processing for weaned pigs' diets.
Extruder or expander processing of diets could reduce
palatability and ileal digestibility of several amino acids
which may have a negative effect on the growth
performance of weaned pigs.
