The forage cattle consume as the bulk of their diet is often deficient in trace mineral concentrations. Cattle producers can choose from a number of different methods to provide supplemental trace minerals to cattle. This 3-page document discusses several common ways to provide trace mineral supplements as well as their advantages and disadvantages. Written by Matt Hersom and Todd Thrift, and published by the UF/IFAS Department of Animal Sciences, October 2018.
In cattle, all physiological processes in the body, including the immune system, are influenced by the cattle’s nutritional status. Therefore, the past and present nutritional status serves as an immune function modulator in cattle that can influence the performance and reproduction of beef cattle.

Approximately 68% of the 16 million square miles of agricultural land worldwide is used for permanent pastures for livestock production. Fortunately, ruminants can convert plant matter that is inedible or of low nutritional value for monogastrics (i.e., swine or poultry) into calorically dense products of high nutritional value. However, the process of converting poor quality plant matter into useful nutrients for ruminants is complex. This 3-page fact sheet provides an overview and understanding of how forage composition and structure affect the nutritive value and nutrient availability to ruminants. Written by Kalyn M. Waters, Nicolas DiLorenzo, and G. Cliff Lamb, and published by the UF Department of Animal Sciences, March 2013.
Beef cattle producers should consider using ionophores to increase calf gain and gain efficiency in a cost-effective manner. Ionophores are feed additives used in cattle diets to increase feed efficiency and body weight gain. They are compounds that alter rumen fermentation patterns. Ionophores can be fed to any class of cattle and can be used in any segment of the beef cattle industry. Similar to many other feed additives, ionophores are fed in very small amounts and supplied via another feedstuff as carrier for intake. Ionophores decrease incidence of coccidiosis, bloat, and acidosis in cattle.

Forage should provide the majority of the nutrition for the beef herd. Seasonal forage growth and changes in forage quality challenge most cattle managers to provide adequate nutrition at reasonable costs. This 6-page fact sheet gives several alternatives to consider in your cow-calf production system. Written by Matt Hersom and W.E. Kunkle, and published by the UF Department of Animal Science, October 2011.
