Ruminal Biohydrogenation

Four sheep cannulated in the rumen and proximal duodenum were used in a 4 × 4 cross-over design to investigate the effects of ruminal fatty acid (FA) infusion on duodenal and serum FA profiles. The diets were composed of 85.7% natural grassland hay and 8.6% concentrate supplemented with 5.7% soy oil for diet SO, 5.7% emulsified soy oil for diet ESO, 6.7% calcium salts of soy or palm FA for diets CaSSO and CaSP, respectively. Diets were formulated to be isonitrogenous and isoenergetic; total FA content in dry matter was 6.4–6.6%. Characteristics of ruminal fermentation were not affected by source or physical form of FA. The proportion of stearic acid in the duodenal flow (% of the total C18) was high compared with total diet, e.g., 49.8 vs. 3.5 and 54.3 vs. 9.4% for soy and palm diets, respectively. Ruminal biohydrogenation and unsaturated FA was lower for CaS diets than for SO and ESO diets (48.7 and 60.9 vs. 81.2 and 94.7%, for oleic and linoleic acids, respectively). As a result, trans-vaccenic acid levels in duodenal flow and serum (% or total FA) were lower for the CaS diets than for SO and ESO diets (8.3 vs. 36.0% and 0.9 vs. 7.8%, respectively). Unsaturated FA as CaS were partly protected against ruminal biohydrogenation, and can be effective in increasing intestinal absorption of unsaturated FA.

Based on the potential benefits to human health, there is interest in developing sustainable nutritional strategies to enhance the concentration of long-chainn-3 fatty acids in ruminant-derived foods. Four Aberdeen Angus steers fitted with rumen and duodenal cannulae were used in a 4 × 4 Latin square experiment with 21 d experimental periods to examine the potential of fish oil (FO) in the diet to enhance the supply of 20 : 5n-3 and 22 : 6n-3 available for absorption in growing cattle. Treatments consisted of total mixed rations based on maize silage fed at a rate of 85 g DM/kg live weight0·75/d containing 0, 8, 16 and 24 g FO/kg diet DM. Supplements of FO reduced linearly (P < 0·01) DM intake and shifted (P < 0·01) rumen fermentation towards propionate at the expense of acetate and butyrate. FO in the diet enhanced linearly (P < 0·05) the flow oftrans-16 : 1,trans-18 : 1,trans-18 : 2, 20 : 5n-3 and 22 : 6n-3, and decreased linearly (P < 0·05) 18 : 0 and 18 : 3n-3 at the duodenum. Increases in the flow oftrans-18 : 1 were isomer dependent and were determined primarily by higher amounts oftrans-11 reaching the duodenum. In conclusion, FO alters ruminal lipid metabolism of growing cattle in a dose-dependent manner consistent with an inhibition of ruminal biohydrogenation, and enhances the amount of long-chainn-3 fatty acids at the duodenum, but the increases are marginal due to extensive biohydrogenation in the rumen.
