Behavioral Associations during a Novel Object Test and Performance of Barrows Divergently Selected for ResidualFeed Intake

Selection for decreased RFI is controversial from a welfare standpoint, given that the genetic variation in RFI reflects the genetic variation in activity and response to stress. The objective of this experiment was to examine the behavioral metric correlations and growth performance of barrows divergently selected for residual feed intake (RFI) during a novel object test. Forty ...

Effect on Gilt Behavior and Postures when Selected for Residual Feed Intake Selection in Response to a Lipopolysaccharide Challenge

The objective of this study was to determine low and high-RFI gilt sickness behavior when challenged with lipopolysaccharide (LPS). This work was conducted with seven low residual feed intake gilts (RFI) and eight high RFI gilts (63±4 kg BW) from the 8th generation of the ISU Yorkshire RFI selection lines. Gilts were challenged intramuscularly with 30 µg/kg BW Escherichia coli ...

Association of Different Iowa Livestock Truck Wash Stations Service Levels with Enterobacteriaceae Counts

Data from eighteen different truck washes were used to compare the association of different service levels with Enterobacteriaceae counts. Service levels were classified into three different categories; prewash (n=78), post wash with disinfectant (n=78), and post wash without disinfectant (n=12). A total of 168 drag swabs were used for collection for the purpose of this study. ...
