Increasing Feed Efficiency by Attenuating the Transportation Stress Response in Nursery Piglets through L-Tryptophan Supplementation

The objective of this experiment was to mitigate the adverse effects of early life transport stress on subsequent immune challenges by providing supplemental Tryptophan (Trp) during the nursery period.

Utilization of an Advanced Computer Vision Platform to Identify Changes in the Physiological and Behavioral Changes Associated with Illness and Aggressive/Damaging Behavior During the Nursery and Finisher Phase

Overall results indicate that precision livestock technology has the ability to provide accurate identification of compromised pigs and there is potential for precision livestock technology to provide caretakers with an early-alert system for the identification of compromised pigs.

Evaluation of Late Finishing Space Allowance and Marketing Strategy and the Strategic use of Hyper-Doses of Phytase to Improve Production Performance and Profits

This project was designed to evaluate the impacts that hyper-dosing levels of phytase (defined here as 4,500 to 5,000 FTU/kg of feed) on growth performance, carcass characteristics, and serum chemistry of late-finishing pigs housed under space restriction or marketed using two different marketing strategies.

Assessing the effects of farrowing crate design and mothering phenotype on pre-weaning piglet survival and performance using imaging technologies

Actual piglet mortality is a combination of a set of complex interactions between sow, piglet, environmental, and management factors. While crushing by the sow may be the ultimate cause of piglet mortality, there are many factors influencing the outcome, including hypothermia, starvation, and others. This study’s goals were to create a better environment for the piglets and the sow and to work towards methods of selecting sows with better mothering ability.

Improving feed efficiency of growing to finishing pigs fed high DDGS containing diet with different branched-chain amino acids to lysine ratio
Corn distillers dried grains with solubles (cDDGS) can replace portions of corn and soybean meal (SBM) in swine diets. However, high dietary inclusions of cDDGS can reduce growth performance, which...

An Integrated Approach to Improve While Herd Pig Survivability
Pre-weaning survival in US herds ranges from 80-90% with the majority of the death loss occurring in the first three days after birth from crushing from the dam. Risk factors for mortality are low...

Development of an Integrated Computerized Sensing System for Reproductive Management of the Swine Breeding Herd
Modern breeding farms rely on consistent flow of pigs through the production system. Reduced fertility can seriously disrupt animal production, flow and profit. These problems can originate from an...

SNORT: Swine Nutritional Observation and Routing Technology
This project developed SNORT (Swine Nutritional Observation and Routing Technology), a software application that leverages innovations in visual sensemaking for in situ detection, tracking, and...

Optimizing late finishing pig feed efficiency, carcass yield, and economic return

The multi-facetted project focused on optimizing late finishing pig feed efficiency, carcass traits, and economic return through feeding practices is essential for the sustainability of pork production.

Animal Science
Interactive effects of pelleting and particle size reduction of corn on net energy and amino acid digestibility in corn-soybean meal diets fed to group-housed pigs

The objective of this research was to demonstrate interactive effects of pelleting and reducing particle size of corn on net energy and nutrient digestibility in feeds for growing pigs.
