In summary, the results of our experiments suggest
that the inclusion of SPC from source 2 leads to better
performance in weanling pigs then does SPC from
source 1. When given a choice between a diet containing
40% SBM or a diet containing 28.6% SPC from
source 2, pigs prefer to eat the diet containing 40%
SBM. It seems that SBM cannot be fully replaced by
SPC while avoiding adverse effects on pig growth performance.
Our results suggest that approximately 14
to 21% SPC from source 2 can be included in the diet
for weanling pigs to optimize growth performance.
