Nebraska student studies palm oil in feedlot

By Scout Nelson

Anna Kobza, a doctoral student at the University of Nebraska-Lincoln, is conducting research on the use of supplemental fat in feedlot diets, specifically focusing on palm oil as an alternative fat source. Her research also examines how a feed additive can enhance fat digestibility.

“Fat is commonly fed to increase the energy density of the diet without increasing the starch content, which comes from grain,” Kobza explained. “Reducing the starch content reduces the risk for digestive disorders.” Preliminary data suggests that palm oil could be a viable alternative to traditional fat sources such as corn oil and tallow. Digestion trials for the feed additive are currently ongoing.

In addition to her research, Kobza serves as the research coordinator for metabolism and digestibility labs at UNL. The extensive beef research conducted at the university is shared with producers across Nebraska through Extension educators. These educators also facilitate communication between producers and researchers, helping to address issues faced in the field.

“Our goal is to help the producers in our state do what they do better and provide them resources to understand how to do that,” Kobza said.

Kobza’s journey into the beef industry began in 4-H, where she showed horses and developed an interest in beef projects. Although she did not grow up on a farm, she borrowed breeding heifers from a local producer, which sparked her passion for beef.

She pursued her undergraduate studies in animal science at UNL and later completed her master’s in feedlot nutrition at West Texas A&M University.

Noticing a lack of representation for cattle feeders on social media, Kobza began sharing her experiences in the feedlot. “What’s also important to me is teaching other producers in the beef industry how to communicate with consumers more effectively and how to discuss difficult topics,” she noted.

Through her social media presence, Kobza engages over 90,000 followers, aiming to educate consumers about beef production practices.

She plans to work as a consulting feedlot nutritionist after completing her doctorate, helping producers across the Midwest and High Plains. Kobza is also excited to move to her fiancé’s family ranch, continuing her commitment to the beef industry.
