1)
Values are presented as the least squares mean of 6 replicates.
2)
CON, control sow diet based on corn and soybean meal; SDP, CON + 1% spray-dried plasma.
3)
The 3-phase feeding program with basal nursery diet was used to feed weaned pigs: week 1 as phase 1; week 2 as phase 2; and week 3 to 6 as phase 3. Pigs had free access to water and diets throughout the experiment.
BW, body weight; ADG, average daily gain; ADFI, average daily feed intake; G:F ratio, gain to feed ratio.
