Controllers and sensors
As part of the brochure ‘Managing energy cost in the barn’, this section talks about the do’s and don’ts of controllers and sensors and shows the economical implications of improper settings or calibration of the controllers. To access this specific section, go to 'Controllers and sensors'....

Response of growing hogs to the inclusion of hybrid rye in low or high energy diets
Hybrid rye has the potential to be a cost-effective ingredient in swine diets. Several studies observed slightly reduced feed intake for pigs fed increasing hybrid rye substituting for wheat or corn, which in turn resulted in lower average daily weight gain. Typically, the growing pig...

New and alternative sanitization procedures for antibiotic-free swine barns
Certain barns that switched to antibiotic-free production observed increased prevalence of pathogens after a few years on the program. Developing improved sanitization and disinfection procedures is an important step to reduce the pathogen load in antibiotic-free barns, which was the goal of this study. This project identified...

Effects of gestation sow grouping practices on aggression and production
A concern with any type of group housing is the aggression performed when mixing unfamiliar sows into a group, as they compete to form a social hierarchy. Ongoing aggression is another related concern. It is important to understand how different grouping practices influence sow aggression,...

Dietary nitrogen content affects lysine requirement and nitrogen utilization and retention in growing pigs
When dietary protein is reduced by more than 3%, non-essential amino acids or total dietary protein may become limiting for maximum nitrogen (N) retention (i.e., lean gain) and growth performance. It has been suggested that the ratio of essential amino acid-nitrogen to total nitrogen (E:T)...

Inclusion of non-protein nitrogen and lysine in grower pig diets on growth performance
Results from our previous study demonstrated that inclusion of non-protein nitrogen (NPN) in a diet with a high essential amino acid-nitrogen:total nitrogen (E:T) ratio (i.e. limiting in total nitrogen [N]) increased the Lys requirement and maximum N retention in growing pigs. A growth performance study...

Inclusion of non-protein nitrogen in grower pig diets on lysine requirement for maximum nitrogen retention
Low protein diets have improved nutrient utilization while maintaining animal performance. However, these diets may be limiting in nitrogen (N) content to meet non-essential amino acid (NEAA) requirements, potentially altering essential amino acid (EAA) utilization and requirements. Inclusion of a source of non-protein nitrogen (NPN)...
