‘MTSU On the Record’ horses around with citrus-pulp nutrition idea [+VIDEO]

A recent edition of the “MTSU On the Record” radio program dug into the feedbag in search of interesting developments in equine nutrition.

Host Gina Logue’s interview with Dr. Rhonda Hoffman, professor of horse science in MTSU’s School of Agribusiness and Agriscience, first aired Jan. 12 on WMOT-FM (89.5 and ). You can listen to their conversation here.

Hoffman was a consultant on carbohydrate nutrition for a study conducted at the University of Sao Paulo in Brazil. The researchers found that citrus pulp could make up as much as 28 percent of a horse’s diet.

A byproduct of Brazil’s orange juice industry, citrus pulp is inexpensive and readily available.

The horses in the study found it both palatable and easily digestible, and none rejected the pulp.

“To me, that’s kind of surprising, because I cannot imagine (the horses) eating orange peel, even ground up in small amounts, unless you added a whole bunch of sugar,” said Hoffman.

“And they had no molasses or sugar added to this.”
