Student: Vazquez, Maria Poster Title: Mitigating Methane Emissions from Enteric Fermentation in Beef Cattle Using Three Herbs Abstract: Methane produced by enteric fermentation is one of the main contributors of greenhouse gases in the agricultural sector. Among the current mitigation strategies, is the incorporation of plants with a high content of secondary metabolites in the animal diet. In the present study, two experiments were carried out, with the aim of evaluating the antimethanogenic effect in vivo of Cymbopogon citratus (CC), Matricaria chamomilla (MC) and Cosmos bipinnatus (CB); and the inclusion of increasing levels of CC (0%, 2%, 3%, and 4% of the daily dry matter intake (DMI)) in the diet of beef cattle. In experiment 1, eight Charolais x Brown Swiss steers were used distributed in a Latin square 4 × 4 design repeated twice, they were fed a 19.4% forage and 80.6% concentrate diet; and 4 treatments were evaluated: 1) control diet (CO), 2), CO + 365 g dry matter (DM) / d CB, 3) CO + 365 g DM / d MC, 4) CO + 100 g DM / d CC. In experiment 2, four Charolais x Brown Swiss steers were distributed in a 4 × 4 Latin square design, and were fed a 49.3% forage and 50.7% concentrate diet. In experiment 1, it was observed that 100 g DM / d of CC and 365 g DM / d of CB reduced the methane yield with respect to CO by 32.5% and 27.6% respectively (P < 0.05). In experiment 2, CC had a quadratic effect, showing the lowest methane production at the 2% DM inclusion level, with the digestibility of DM, fibers and energy following the same trend (P < 0.05). It is concluded that CC reduces methane production but the effects depend on the diet, level of inclusion and content of secondary metabolites.

Feedback to Student: Below are all of the comments from judges on your presentation. Great work! Very nice presentation, both poster and oral, and very well explained. Nice images and animations. My recommendation is that when you include a table in your poster, make sure they are clearly explained or very easy to interpret. There is a lot of information on your tables, but it is very hard to understand what you want to show or highlight from them. Also, I could not connect the percent reductions you talked about in your results to the numbers I was seeing in the tables.
I would also recommend using contrasting colors for the poster (background vs. font color). I understand it is a matter of personal taste, but some people can complain that it is a little hard to read the text in black against a dark (dark blue) background. I think it is easier to read, for example, when you use (as in your presentation) black vs. white or any other very contrasting combination. It is, definitely, a suggestion, because I think this is more of a personal taste level.
Overall, great work! All the best and keep up with your research! This is a very well done research work and should be submitted as a manuscript to a peer-reviewed journal.
