Based on previous results showing partial resistance of fatty acyl amides to ruminal biohydrogenation, butylsoyamide was added to sheep diets in an attempt to increase unsaturation of plasma fatty acids. Twelve wethers averaging 34 +/- 3.2 kg BW were randomly assigned to three diets containing either no added fat (control), 5% soybean oil, or 5% butylsoyamide. Dry matter intake was greater (P <...

There are no reported pathways of docosahexanoic (DHA) biohydrogenation; however, DHA is metabolized by ruminal microorganisms. In this study a 0.5mg pulse dose of uniformly 13C labeled DHA in ethanol was injected at 0h as a metabolic tracer. This study did not examine every fatty acid metabolite, but rather identified several saturated and trans-18:1 fatty acid metabolites and set a foundation...

Essential oils (EOs) from plant extracts have been reported to have an antibacterial activity against gram-negative and gram-positive bacteria. Several of the gram-positive bacteria are involved in ruminal biohydrogenation of fatty acids (FAs), thus suggesting that feeding EOs could lower biohydrogenation of FA because of a decrease in the number of bacteria involved in that process. As a resul...

in pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...
