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.

Spray-dried bovine plasma was selected as a positive control protein source used in Exp. 2 because to the authors knowledge no publications have reported performance comparisons of pigs fed diets with SDBP versus APP. Bovine plasma may vary slightly in amino acid composition from porcine plasma, however each source contains similar profiles of globulin, albumen, and other proteins with biological activity and both sources of plasma have demonstrated increased performance of pigs when compared to other non-plasma protein sources (Torrallardona, 2010) . Growth of pigs fed SDBP vs. SDPP was not different when each source was included at 6% of the diet, and pigs fed SDPP had higher ADFI, but lower G:F than pigs fed SDBP . In a review of other studies where SDBP and SDPP were compared at the same dietary levels within the study (Torrallardona, 2010) , performance results favoring either SDPP or SDBP were variable across studies, but most reported higher feed intake for pigs fed SDPP.
