A.  aTheree methods of determining diet, utilization, and trampling damage on sheep ranges.h[electronic resource]  c1972  aEsophageal fistula sampling and ocular utilization estimates gave similar figures for dietary composition and for percentage utilization by sheep for most plant species in the tall-forb type. The paired-plot method gave higher utilization figures than the methodes because it estimated not only herbage eaten, but also that trampled. As a result, this method overestimated the dietary composition of species most susceptible to trampling damage; trampling accounted for one-half to two-thirds of the herbage removed by grazing.  aGrazing  aRangelands  aSheep feeding  aDieta  aFistula Esofágica  aOvino  aComposicao1 aBUCHANAN, H.1 aKRUEGER, W.
