Abstract
Describing PRRSV whole-genome viral diversity data over time within the host and within-farm is crucial for a better understanding of viral evolution and its implications. A cohort study was conducted at one naïve farrow-to-wean farm reporting a PRRSV outbreak....

It is important that the digestibility of Ca in Ca sources is known to formulate diets based on values for digestible Ca rather than total Ca. Only a small amount of the Ca required by pigs is provided by...
Abstract
OBJECTIVE
The purpose of this case study was to describe the transmission of porcine reproductive and respiratory syndrome virus (PRRSV) under field and experimental conditions via the consumption of PRRSV-positive swine feed.
ANIMALS
1 domestic swine breeding herd and 20 laboratory-maintained experimental...
Abstract
Data from Europe indicate that commercial diets for pigs and poultry contain significantly more Ca than formulated. Therefore, a survey of commercial pig diets used in the United States was conducted to test the hypothesis that the analyzed concentrations...

Porcine Reproductive and Respiratory Syndrome (PRRS) has proven to be a persistent and adaptive viral adversary to the North American swine industry for over 30 years. Hypothesized to have arrived in North America as...
Biomarkers are objective and quantifiable characteristics of biological processes. There are many measures taken to evaluate acute experiences that influence animal welfare, such as measurement of cortisol, a hormone that increases in acute stress after aggression. There is currently...
Abstract
Porcine parainfluenza virus 1 (PPIV-1) is a recently characterized swine respirovirus. Previous experimental studies reported PPIV-1 replicates in the porcine respiratory tract causing minimal clinical disease or lesions. However, it is unknown if PPIV-1 co-infections with viral respiratory pathogens...
Drip loss or purge is the loss of fluid from the carcass, it is the opposite of water retention. It is economically important in several ways.

Abstract
The swine and agriculture industries have consistently been searching for increased methods for improving efficiency. This study addressed this concern through measuring sow activity traits and lesions in order to identify associations with lameness and gilt retention. Culled females...
