Welcome to the Agri-environmental Research Data collection.

The Agri-environmental Research Data collection was established by the University of Guelph Library in 2012 with the assistance of the Ontario Ministry of Agriculture, Food and Rural Affair's (OMAFRA) Knowledge Translation and Transfer (KTT) Funding Program. The purpose of this collection is to provide access to, and long-term stewardship of, agricultural and environmental datasets created at or in cooperation with the University of Guelph.

The Cross-disciplinary Research Data collection houses datasets for all other disciplines at the University of Guelph.

Begin a deposit: The library offers a self-deposit with curation service. First time depositor? Complete the U of G Research Data Repositories New Depositor Intake Form. Already have dataset creator access to your home department's collection? Simply log in using your U of G username and password and begin a new deposit.

Guidance materials for preparing your research data for sharing and long-term access and instructions on how to deposit your data in the Agri-environmental Research Data collection can be accessed at How to deposit research data in the University of Guelph Research Data Repositories.

Mar 5, 2026 - Department of Animal Biosciences
Rentsch, Ana; Gautamadasa, Sachin; Hanlon, Charlene; Bédécarrats, Grégoy Y., 2025, "Supplemental data for: Transient behavioral effects of feed restriction in a white feathered laying hen pullet strain: Assessment of frustration and locomotor energy expenditure", https://doi.org/10.5683/SP3/EUQVJU, Borealis, V2, UNF:6:obeM6w4/0wF6p6e//drR2w== [fileUNF]
This study aimed to assess any negative welfare consequences of using quantitative feed restriction to slow the growth of laying hen pullets. Pullets were raised in furnished floor pens in a split-plot design: Two ages at photostimulation (18 weeks: early-PS vs 20 weeks: late-PS) with two feeding regimens each (ad libitum: AL vs 20%-restricted: R)...

Effects of Bacillus subtilis fermented canola meal on nutritional characteristics and growth performance of nursery pigs
Mar 5, 2026 - Department of Animal Biosciences
Li, Boning; Zimo, He; Churcher, Jessica; Hicks, Thomas; Yien, Justin Sze-Yan; Xu, Mingli; Niu, Yanxing; Rogiewicz, Anna; Li, Julang, 2026, "Effects of Bacillus subtilis fermented canola meal on nutritional characteristics and growth performance of nursery pigs", https://doi.org/10.5683/SP3/4XJ49N, Borealis, V1, UNF:6:5ihZD7bQz7Ke2iU7hS0zDQ== [fileUNF]
Canola meal (CM) is widely produced in Canada, but its use in swine diets is limited due to the presence of anti-nutritional factors (ANFs). This study investigated whether solid-state fermentation (SSF) with two Bacillus subtilis strains, BS9 and L5, could improve the nutritional quality of CM and its functional effects in nursery pigs. Canola mea...
