Review: Trans-forming beef to provide healthier fatty acid profiles
(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
(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, ...
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
(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 ...
Association analyses of DNA polymorphisms in bovine SREBP-1, LXRα,FADS1 genes with fatty acid composition in Canadian commercial crossbred beef steers
(Elsevier, 2013-03)
Two previously reported DNA polymorphisms of sterol regulatory element binding transcription factor 1 (SREBP1) and liver X receptor alpha (LXRα) and two DNA
polymorphisms of fatty acid desaturase 1 (FADS1) were evaluated ...
Length of concentrate finishing affects the fatty acid composition of grass-fed andgenetically lean beef: an emphasis on trans-18:1 and conjugated linoleic acid profiles
(2011)
Intensively finishing cattle on a high-grain diet is generally used to enhance marbling, whereas extensively finishing on grass is
known to provide improved muscle fatty acid profiles. The objective of this study was to ...
Survey of the fatty acid composition of Canadian beef: Backfat and longissimus lumborum muscle
(Agricultural Institute of Canada, 2009-09)
[EN]A survey of Canadian retail beef was undertaken with emphasis on the trans fatty acid (TFA) and conjugated linoleic acid (CLA) isomers, and compared with current health recommendations. Thirty striploin steaks were ...
Subcutaneous fat composition of youthful and mature Canadian beef: emphasis on individual conjugated linoleic acid and trans-18:1 isomers
(Agricultural Institute of Canada, 2008-12)
[EN]A comprehensive evaluation of the fatty acid composition of subcutaneous adipose tissue from beef cattle produced in western Canada was undertaken to determine if the current Canadian grading system is able to distinguish ...
Phenotypic correlations of fatty acid composition among intramuscular, subcutaneous and intermuscular fat tissues in concentrate-fed beef cattle of differing genotypes
(Agricultural Institute of Canada, 2009-03)
[EN]In an attempt to predict intramuscular fatty acid composition using easily accessible fat depots, between-tissue correlations were studied in 75 Asturiana de los Valles bulls with different levels of muscular hypertrophy, ...
Rapid determination of total CLA concentration in beef fat
(Agricultural Institute of Canada, 2007-06)
[EN]Conjugated linoleic acid (CLA) has many potential healthful properties, and beef is naturally enriched with CLA. Simple and rapid methods to measure total CLA were investigated to enable sorting of beef carcasses with ...
Evaluation of wheat or corn dried distillers' grains with solubles on performance and carcass characteristics of feedlot steers
(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% ...
