Impact Of Ph And Palmitic Acid On Ruminal Fermentation And Microbial Community Composition, Lexie Padilla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this study was to evaluate the effects of dietary palmitic acid and pH on rumen fermentation, fiber digestibility, and bacterial community composition. The two factors in the experiment were palmitic acid treatment and pH treatment. Palmitic acid treatments included a control diet compared to a diet containing 1.5% palmitic acid. pH treatments included normal pH (6.6 to 7.0) compared to low pH (6.0 to 6.4). Rumen fluid from a cow was added to artificial rumens to study the effects of the two treatments relative to fermentation and changes within the microbial community. Results of the study showed …
