Im. Ortega et al., CONTRASTS OF ESOPHAGEAL-FISTULA VERSUS BITE-COUNT TECHNIQUES TO DETERMINE CATTLE DIETS, Journal of range management, 48(6), 1995, pp. 498-502
To understand how different techniques might affect diet estimates for
cattle, the esophageal-fistula and bite-count techniques were compare
d using trained cattle, For the Texas Coastal Bend, bite-count was not
as reliable a technique as the esophageal fistula, These techniques d
iffered in estimation of forage classes and plant species in cattle di
ets, The esophageal-fistula technique was more accurate however, the b
ite-count technique may be acceptable if analyses are limited to only
those plant species making up >2% of the diet.
