Pig breeding programs traditionally focus on the genetic improvement of production and
reproduction traits that have a clear economic value. Because citizens and consumers …

Porcine reproductive and respiratory syndrome (PRRS) is the most economically important
disease in pig populations, worldwide. Current research, both in vitro and in vivo, has failed …

A total of 339 full-sib families (representing 143 paternal half-sib families) and 337 full-sib
families (representing 145 paternal half-sib families) were respectively challenged with …

Residual feed intake (RFI) is a complex trait that is economically important for livestock
production; however, the genetic and biological mechanisms regulating RFI are largely …

Background The understanding of host genetic variation in disease resistance increasingly
requires the use of field data to obtain sufficient numbers of phenotypes. We introduce …

Land‐based production of high‐quality protein by livestock and poultry plays an important
role in improving human nutrition, growth, and health, as well as economical and social …

This book has been written in response to three stimuli. First, all over the world there is
evidence that the diversity of domesticated animals is under threat and students, opinion …

A general model is proposed for predicting the effects of subclinical pathogen challenges of
different doses and virulence on the relative feed intake (RFI) of animals. The RFI is defined …

ABSTRACT One hundred Hampshire× Duroc cross-bred pigs (HD) and 100 NE Index line (I)
pigs were infected with porcine reproductive and respiratory syndrome (PRRS) virus and …

The objective of this study was to determine whether host genetics play a role in
susceptibility to the respiratory disease in growing pigs caused by the porcine reproductive …
