NMSU Animal Science Department Adds Livestock Nutritionist

LAS CRUCES - Shanna Lodge-Ivey has joined New Mexico State University's animal and range sciences department as a new livestock nutritionist specializing in microbiology.


The Albuquerque native will take a new approach to research on toxic range plants and their effect on livestock production.

"We still don't know what many of the toxins are in several of New Mexico's most troublesome range plants or how they change in the animal's gastrointestinal tract or tissues," Lodge-Ivey said.

"Once we figure out what the toxin is doing, then we can look at developing a vaccine to protect the animal," she said. "This will hopefully save producers money and create more efficiency in the future."

Her studies will be conducted at NMSU and the university's 27,000-acre Corona Range and Livestock Research Center. The working ranch laboratory is located near the center of the state, just east of the village of Corona.

Lodge-Ivey will also work on developing a new way to assess nitrogen metabolism in cattle. "Our long-term goal is to develop a new way to determine whether these animals need supplementation," she said. "One way to do that is to determine protein deficiencies during specific times of the year."

In addition to her research, she will teach animal science courses on nutrition and metabolism.

Prior to joining NMSU, Lodge-Ivey served 2.5 years as a postdoctoral fellow at Oregon State University's College of Veterinary Medicine. Her research centered on identifying of toxins in endophyte-infected tall fescue straw. An endophyte is a fungus that lives inside the grass plant.

She also worked 3 years as a clinical research administrator for Greenfield, Ind.-based Elanco Animal Health, a division of Eli Lilly and Company.

Lodge-Ivey is a member of the American Society of Animal Science and the American Society for Microbiology.

She earned a bachelor's degree in animal science from NMSU and master's degree in ruminant nutrition from the University of Nebraska. She received a doctorate in rumen microbiology from NMSU.
