Fermented soybean meal may replace fish meal in diets fed to pigs during the initial 28 days post-weaning without affecting average daily gain or body weight.
Fermented soybean meal cannot replace protein plasma and whey powder during the first week post-weaning without negatively affecting growth performance.
During the second and third week after weaning, it is possible to use FSBM rather than protein plasma and whey powder. This is most likely because the lactose in whey powder and the immunoglobulins in protein plasma are most beneficial to the pig in the first week post-weaning.
