Brahman-type cattle may require less nitrogen | AgriLife Today – AgriLife Today



A recently funded Texas A&M AgriLife study will determine differences in nitrogen requirements between Brahman type cattle and other cattle. Measuring these differences may allow cattle producers to reduce the protein in cattle diets by allowing for precise diet formulations.

“Implementation of precision diet formulation in cattle diets can be the answer to producing a more affordable beef with a smaller environmental impact,” said Tryon Wickersham, Ph.D., Texas A&M AgriLife Research, scientist and associate professor in the Department of Animal Science in the Texas A&M College of Agriculture and Life Sciences.

“We believe development of feeding systems that account for differences in cattle type will reduce over and under supplementation, allowing us to optimize growth, reproduction and animal health outcomes,” Wickersham said. “Additionally, precise feeding systems will reduce the environmental footprint of beef production.”

Different cattle subspecies, different nutritional needs

Cattle are divided into two subspecies, Bos taurus taurus, which generally have no hump and originate from Europe, and Bos taurus indicus, generally having a
