Abstract

The objective of this experiment was to measure the apparent (AID) and standardized (SID) ileal digestibility of crude protein (CP) and amino acids (AA) in yeast extract and spray dried plasma protein (SDPP) by weanling pigs. A casein-based diet, a casein-SDPP diet, a casein-yeast extract diet, and a N-free diet were formulated and fed to weanling pigs. Values for AID and SID in yeast extract and SDPP were calculated using the difference procedure. Results showed that the AID for CP and all AA with the exception of Cys and Ser are similar between yeast extract and SDPP. Likewise, no differences in SID for CP or AA were observed between yeast extract and SDPP. The current data demonstrate that both yeast extract and SDPP contain protein that is relatively well digested by young pigs.
