Experimental diets were fed from d 0 to 7 (Phase I) and from d 8 to 21 (Phase II) after weaning. All pigs received a common Phase III diet from d 22 to 35.
BPSBM+SDP = the CON with bioprocessed soybean meal replacing fish meal.
BPSBM+FM = the CON with bioprocessed soybean meal replacing spray-dried plasma.
BPSBM = the CON with bioprocessed soybean meal replacing both fish meal and spray-dried plasma.
BPSBM = bioprocessed soybean meal (Prairie AquaTech, Brookings, SD).
