Biases in Relative Estimates of Dietary Mineral Status from Esophageal Extrusa [PDF]
Journal of Range Management, 1990 An experiment was conducted to determine whether or not the effects of forage type and time into feeding period precluded use of esophageal extrusa to estimate relative dietary mineral status of cattle. Four esophageally fistulated Angus-Hereford X Jersey crossbred steers (340 to 545 kg.) were alternately fed Coastal bermudagrass hay (Cynodon dactylon)
