Factors Affecting Preweaning Piglet Mortality
Part 1
Generally, it’s difficult to attribute a single cause to preweaning mortality (PWM). Various predisposing causes and their complex interactions lead to PWM (Figure 1). These predisposing factors can be...
Pigs get stressed out for lots of reasons, but weaning, heat, crowding, transportation and related challenges can weaken their immune system and make them more vulnerable to disease and performance losses. This particularly holds true for gastrointestinal (GI) disorders,1...

With more ethanol in production and a greater ability to upcycle co-products into animal feed ingredients, companies are creating custom products and partnering with University of Illinois researchers to test for quality and digestibility.
In a recent study published in...
Abstract
Aim
This study aimed to evaluate the patterns and potential risk factors associated with the occurrence of Salmonella sp. and Escherichia coli in selected United States swine feed mills.
Methods and Results
A total of 405 samples were collected during...

Introduction
Physiological changes associated with immediate pre-slaughter stresses, i.e. increased exsanguination blood lactate concentration, have been shown to have detrimental effects on pork quality causing increased drip loss and lighter color (Hambrecht et al., 2004, 2005; Warriss et al., 1994,...
Several experiments were conducted to estimate Ca digestibility in different feed ingredients in the presence or absence of microbial phytase to allow formulation of diets for pigs to be based on standardized total tract digestible (STTD) Ca instead of...
Highlights
•
A "manureshed" encompasses the lands surrounding animal feeding operations onto which manure nutrients can be redistributed to meet environmental, production, and economic goals.
•
3109 U.S. counties were classified as sources or sinks of manure nutrients.

A large portion of sows removed from commercial breeding herds in the U.S. are due to lameness. Previous data suggest levels of P fed to developing gilts may be below that required for maximal skeletal development, and that microbial...
