University of Florida Project to Select the Best Brahman Genes

With help from cattle producers through the Florida Cattle Enhancement Fund, UF/IFAS researchers hope to develop Brahman cattle that can tolerate heat better, produce more tender meat and improve their fertility.

University of Florida Institute of Food and Agricultural Sciences researchers would like Brahman cattle owners from around Florida to participate in the project. First, they need data from ranchers.

Over the next two years, researchers will collect pedigree data and records from producers as scientists hope to identify animals with superior marbling, tenderness and fertility, said UF/IFAS animal sciences associate professor Raluca Mateescu.

“Continued evaluation and selection of superior animals will lead to a genetically improved Florida Brahman population over the coming years,” Mateescu said. “The goal is to genetically improve the purebred Brahman population in Florida so when these animals are used in crossbreeding programs, they produce superior offspring.”

Florida beef cattle populations are mostly crossbred between Angus and Brahman — Brangus, she said. The purebred Angus cattle do not perform well in Florida’s hot, humid subtropical environment. While the Brahman do perform well in the Florida environment, they tend to be not as tender, marble less and have fewer calves.

If scientists can find the superior Brahmans for tenderness, marbling and fertility, they can improve those traits over time, Mateescu said. Superior cattle are kept as parents to produce the next generation.

“The next generation will be superior to the old one if the genetic evaluation is accurate,” she said. The more data UF/IFAS researchers can collect from ranchers, the more accurate their genetic predictions will be.

“This is what we’ve done in the UF/IFAS herds for more than 30 years; we were able to show genetic improvement in meat tenderness, marbling and productive ability,” Mateescu said.
