Evaluation of Late Finishing Space Allowance and Marketing Strategy and the Strategic use of Hyper-Doses of Phytase to Improve Production Performance and Profits
September 19, 2023By Eric Van Heugten
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.

Improving feed efficiency of growing to finishing pigs fed high DDGS containing diet with different branched-chain amino acids to lysine ratio
March 4, 2023By Ryan Samuel
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...

Quantifying the Presence of Viral Material in Feed Delivered in Iowa
May 20, 2022By Trey A. Kellner
Despite evaluating a feed sample for 14 feed mills for 16 weeks, there was no detection of PRRSV, PEDV, PDCoV, and TGEV in any of the 224 collected feed samples. These results do not disprove that...

Improving performance of finishing pigs with supplemental Val, Ile, and Trp: Validating a meta-analysis model
November 24, 2021By Jason Woodworth
Branched-chain amino acids (BCAA) are a collective group of amino acids (AA) made up of Leucine (Leu), Valine (Val), and Isoleucine (Ile). These three AA all share the first steps of catabolism, and...
