Biohydrogenation, Duodenal Flow, and Intestinal Digestibility of Trans Fatty Acids and Conjugated Linoleic Acids in Response to Dietary Forage:Concentrate Ratio and Linseed Oil in Dairy Cows
Open accessAbstract
Duodenal flows of hydrogenation intermediates in response to changes in dietary forage:concentrate ratio (F:C) and linseed oil were evaluated using 4 lactating Holstein cows fed a low (65:35 forage to concentrate) or high (35:65) concentrate diet without (LC, HC) added oil or with linseed oil (LCO, HCO) at 3% of DM. A 4 x 4 Latin square design was implemented for 5 wk. Lower hydrogenation of 18:2n-6 and 18:3n-3 was observed with HC, but it increased with LCO or HCO. Duodenal flow of total conjugated linoleic acids (CLA) increased by 1.40 (LCO) to 3.01 (HCO) g/d with linseed oil. This response was associated with greater flows of cis9,trans11- (+0.21 to +0.55 g/d), trans11,cis13- (+0.33 to +0.36), trans11,trans13- (+1.01 to +1.15 g/d), and trans,trans-CLA (+0.12 to +0.72 g/d). Trans10,cis12-CLA flow averaged 0.08 g/d and was not affected by F:C or oil. trans11,cis15-18:2 flow increased by 8.5 (LCO) to 62 (HCO) g/d in response to linseed oil. Total trans-18:1 flow was 37 g/d in cows fed LC and increased to 81 g/d with HC. Feeding oil increased total trans-18:1 to the greatest extent with HCO. Flow of trans10-18:1 was lower with LC than with HC (1.46 vs. 20 g/d). Linseed oil increased trans11-18:1 flow by 40 (LCO) to 113 g/d (HCO). Feeding LCO and HCO also increased flows of trans6+7+8-, trans13+14-, trans15-, and trans16-18:1. Apparent intestinal digestibility of trans-18:1 isomers was largely unaffected by concentrate level and ranged between 67 and 95%. Linseed oil increased digestibility of nearly all isomers by 3 to 16 percentage units. Digestibility of cis9,trans11-CLA was greater in cows fed HC (55%) compared with cows fed LC (32%) and was not affected by linseed oil. Data suggest that high concentrate diets enhanced ruminal outflow of trans10-18:1. We provide initial in vivo evidence that supplemental 18:3n-3 is hydrogenated to trans11,cis15-18:2, trans11-18:1, trans13+14-18:1, trans15-18:1, trans6+7+8-18:1, and trans16-18:1 primarily.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
