Mineral status of beef cattle in Guanacaste, Costa Rica
Liver and blood samples of three- to four-year-old steers were obtained from 15 farms located in five countries to obtain information on the mineral status of grazing cattle in the Guanacaste region of Costa Rica. Of the livers analysed, approximately 36.0, 30.7, 37.3, 33.3 and 34.7 percent were bordeline to deficient in copper, iron, manganese, selenium and zinc, respectively. Forty nine percent of the blood samples were considered borderline to deficient in phosphorus. There was no significant difference in tissue mineral concentration due to county location, with the exception of selenium. Differences in tissue concentrations among farms were found for all six tissue minerals. In general, tissue minerals could be directly related to use or absence of mineral supplements
