Effects of limonene on ruminal Fusobacterium necrophorum concentrations, fermentation, and lysine degradation in cattle1
Previous in vitro data showed that Fusobacterium necrophorum was inhibited by limonene. We further evaluated effects of limonene on growth of F. necrophorum in vitro as well as on ruminal concentrations of F. necrophorum in vivo. With in vitro cultivation in anaerobic brain-heart infusion broth, limonene decreased growth of F. necrophorum. Thymol also reduced growth of F. necrophorum, but it wa...
متن کاملEffects of 9,10 anthraquinone on ruminal fermentation, total-tract digestion, and blood metabolite concentrations in sheep.
The objective of this study was to evaluate the effects of adding 9,10 anthraquinone, a known inhibitor of methanogenesis and sulfate reduction, on blood metabolites, digestibility, and distribution of gas in sheep. In all experiments, we fed a complete pelleted diet that contained 17.5% crude protein and 24.5% acid detergent fiber. In an 8-wk study, feeding up to 66 ppm (dry matter basis) of 9...
متن کاملRuminal fermentation of propylene glycol and glycerol.
Bovine rumen fluid was fermented anaerobically with 25 mM R-propylene glycol, S-propylene glycol, or glycerol added. After 24 h, all of the propylene glycol enantiomers and approximately 80% of the glycerol were metabolized. Acetate, propionate, butyrate, valerate, and caproate concentrations, in decreasing order, all increased with incubation time. Addition of any of the three substrates somew...
متن کاملRuminant Nutrition: Dairy: Ruminal Fermentation and Health
Treponema saccharophilum was isolated in the early decades and described as highly preferred to utilize pectin for growth. Typically, alfalfa hay contains 10–15% pectin as a component of the cell wall matrix, whereas grass or corn stover has pectin content less than 5%. The objective of this study was to develop a set of PCR primers targeting the 16S rRNA gene of T. saccharophilum and to assess...
متن کاملOptimizing Ruminal Fermentation with Organic Acids
Much interest has been generated over the past few years aimed at evaluating alternative means to manipulate the gastrointestinal microflora in production livestock. Motivation for examining these alternatives comes from increasing public scrutiny about the use of antibiotics in the animal feed industry. However, compared to the amount of information available detailing the effects of antimicro...
