▼a Porcine reproductive and respiratory syndrome virus (PRRSV) and Brachyspira hyodysenteriae (Bhyo) are two economically significant pathogenic agents in which their diseases impact pig production worldwide. Although different nutritional strateg |

▼a In Chapter 2, an experiment was conducted to assess the impact of soybean meal (SBM) and PRRSV on AID, BEL, and calculated SID values of N and AA near peak viremia (5-8 days post inoculation |
| 520 | |
▼a The results from this research indicate that the mechanism by which high SBM improves the outcome of PRRSV challenged pigs does not appear to be related to increased digestibility of N or AA as there were no interactions of SBM and PRRSV (Chapte |

▼a When hindgut disappearance of nutrients and energy were calculated, PRRSV and Bhyo acted in an opposite manner (Chapter 2 and 3, respectively). Compared to control pigs, PRRSV increased hindgut disappearance of DM and GE at peak viremia only. In |

▼a In the final research chapter (Chapter 4), commercial pigs were utilized in an industry style production setting in which we reported that increasing the SID Lys:ME improved growth and feed efficiency in 25 kg BW and 50 kg BW PRRSV challenged pi |

▼a In summary of this dissertation, both systemic/respiratory (PRRSV) and colitis (Bhyo) challenges did not greatly impact ileal digestibility of nutrients, energy, and AA. Further, we did not report major changes in ileal endogenous AA losses, but |
