Short communication: Rapid separation of cis9, trans11- and trans7,cis9-18:2 (CLA) isomers from ruminant tissue using a 30 m SLB-IL111 ionic column

Turner, T.; Rolland, D. C.; Aldai Elkoro-Iribe, Noelia; Dugan, M. E. R. (Agricultural Institute of Canada, 2011-12)

[EN]Rumenic acid (cis9,trans11-18:2) is the main natural isomer of conjugated linoleic acid (CLA). Rumenic acid has many purported health benefits, but effects of most other CLA isomers are unknown. Typically trans7,cis9-18:2 ...

Review: Trans-forming beef to provide healthier fatty acid profiles

Dugan, M. E. R.; Aldai Elkoro-Iribe, Noelia; Aalhus, J. L.; Rolland, D. C.; Kramer, J. K. G. (Agricultural Institute of Canada, 2011-12)

[EN]Trans fatty acids are found naturally in foods, particularly in those derived from ruminant animals, such as beef and dairy cattle. Over the past few decades, human consumption of trans fatty acids has increased, but ...

Extended ageing time and temperature effects on quality of sub-primal cuts of boxed beef

Juárez, Manuel; Larsen, Ivy L.; Gibson, Lorna L.; Robertson, Wayne M.; Dugan, M. E. R.; Aldai Elkoro-Iribe, Noelia; Aalhus, J. L. (Agricultural Institute of Canada, 2010-09)

[EN]Most of the information indicating ageing improves tenderness has been collected on the loin and rib-eye muscles over relatively short ageing times, assuming that all muscles will react similarly. In the present study, ...

Evaluation of wheat or corn dried distillers' grains with solubles on performance and carcass characteristics of feedlot steers

Walter, L. J.; Aalhus, J. L.; Robertson, Wayne M.; McAllister, Tim A.; Gibb, D. J.; Dugan, M. E. R.; Aldai Elkoro-Iribe, Noelia; McKinnon, J. J. (Agricultural Institute of Canada, 2010-06)

[EN]A study was conducted on crossbred steers (n=275; 376±924 kg) to evaluate performance and carcass quality of cattle fed wheat or corn dried distillers’ grains with solubles (DDGS). The control ration contained 86.6% ...

Dietary vitamin E inhibits the trans 10-18:1 shift in beef backfat

Juárez, Manuel; Dugan, M. E. R.; Aalhus, J. L.; Aldai Elkoro-Iribe, Noelia; Basarab, John A.; Baron, Vern S.; McAllister, Tim A. (Agricultural Institute of Canada, 2010-03)

[EN]Forty feedlot steers were fed a barleygrain-based finishing diet typical for western Canada, with two levels of supplementary vitamin E (468 or 1068 IU head_1 d_1) and the effect on backfat trans-18:1 isomeric profile ...
