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 ...
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 ...
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% ...
Dietary vitamin E inhibits the trans 10-18:1 shift in beef backfat
(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 ...
Unveiling the factors shaping the distribution of widely distributed alpine vertebrates, using multi-scale ecological niche modelling of the bat Plecotus macrobullaris
(Biomed Central, 2014-10-29)
Several alpine vertebrates share a distribution pattern that extends across the South-western Palearctic but is limited to the main mountain massifs. Although they are usually regarded as cold-adapted species, the range ...
Sylphella puccoon gen. n., sp n. and two additional new species of aquatic oligochaetes (Lumbriculidae, Clitellata) from poorly-known lotic habitats in North Carolina (USA)
(Pensoft, 2014)
Three new species of Lumbriculidae were collected from floodplain seeps and small streams in southeastern North America. Some of these habitats are naturally acidic. Sylphella puccoon gen. n., sp. n. has prosoporous male ...
What mechanism of niche segregation allows the coexistence of sympatric sibling rhinolophid bats?
(Biomed Central, 2012)
Introduction: Our purpose was to assess how pairs of sibling horseshoe bats coexists when their morphology and echolocation are almost identical. We collected data on echolocation, wing morphology, diet, and habitat use ...
Two new species of Zospeum Bourguignat, 1856 from the Basque-Cantabrian Mountains, Northern Spain (Eupulmonata, Ellobioidea, Carychiidae)
(Pensoft Publishers, 2015)
Two new species of the genus Zospeum Bourguignat, 1856 are described from caves in the Sierra de Aitzgorri (Gipuzkoa) and the Sierra Salvada (Burgos) in Northern Spain. The taxa Z. vasconicum sp. n. and Z. zaldivarae sp. ...
