Effects of specialty proteins as alternatives to bovine or porcine spray-dried plasma in non-medicated diets fed to weaned pigs housed in an unsanitary environment

Crenshaw, J. D.; Campbell, J. M.; Polo, J.; Stein, H. H.

Translate basic science to industry innovation were non-medicated, provided in mash form and fed for the initial 14 d after weaning. The nutrient composition values for the ingredients used for formulation of the diets for both experiments were derived from NRC (2012) or from the supplier of the specialty proteins (Table 3) . Supplier information about the composition of SDP in Table 3 does not distinguish between porcine or bovine origin plasma. Differences in amino acid composition of SDPP or SDBP have been reported that indicate higher Lys, Met, Thr, and Trp in bovine compared to porcine plasma (Torrallardona, 2010 ). In the current experiments, 5% dietary SDPP was (2012) or from the supplier product information for nutrient composition. SPC = soy protein concentrate (Soycomil P, ADM Alliance Nutrition, Quincy, IL); APP = activated porcine plasma (betaGRO, NutriQuest, Mason City, IA); EHSY = enzymatically hydrolyzed soy and yeast protein (Hamlet 800 Booster, Hamlet Protein Inc., Findlay, OH); CB = combination of fish meal, APP, and EHSY; IEGG = spray-dried whole egg from hyper-immunized hens (ProtiMax for Swine, Trouw Nutrition, Highland, IL); SDBP = spraydried bovine plasma (AP920, APC Inc., Ankeny, IA
