The fat composition and mineral content of beef influences both its taste and nutritional value. This study seeks to understand the relationship between meat quality and the nutritional value of beef from Brangus cattle. Animals varied greatly in their levels of essential omega-6 and monounsaturated fat. Higher levels of these fatty acids have been shown to improve the flavor of beef in addition to having a beneficial impact on cholesterol levels. Brangus cattle also exhibited a unique relationship between monounsaturated fat and meat quality, where higher levels of monounsaturated fat were associated with desirable traits such as increased marbling. Regarding mineral content, iron and zinc showed weak negative correlations with monounsaturated fat and moderate positive correlations with polyunsaturated fat. This study sheds light on the complex relations between fat profiles, mineral content, and meat quality. This understanding can inform breeding and management strategies to promote the production of meat that is not only palatable but also beneficial for consumer’s health.
