Measured at d 5 after weaning.
A corn soybean meal basal diet top-dressed with a corn-soybean meal mixture containing 15% crude protein (CP; 12.0 g/d during gestation and 15.0 g/d during lactation). This supplement was given to match the amount of crude protein from the SCFP supplement.
Saccharomyces cerevisiae fermentation product (Diamond V Original XPC, Diamond V, Cedar Rapids, IA) was top-dressed at 12.0 g/d during gestation and 15.0 g/d during lactation.
During 6 phase feeding program from nursery to slaughter, corn and soybean based diets were given to pigs. Nursery diets with SCFP (phase 1 to 3) contained 0.2% Diamond V Original XPC by replacing corn in basal diets. Grower-finisher diets with SCFP (phase 4 to 6) contained 0.1% Original XPC also by replacing corn in basal.
Standard error of means.
Effect from SCFP during gestation and lactation period.
Effect from SCFP during nursery, grower and finishing period.
Backfat thickness at 3 to 4 last rib.
NPPC (2000) scale: 1 represents 1% marbling, 2 represents 2% marbling.
NPPC (2000) firmness scale (1 to 5): 1 = very soft; 5 = very firm.
