In a 3-year study the Herefords spent significantly more time grazing than the Santa Gertrudis, particularly about midnight, but there was no evidence that weather conditions affected the grazing time of either breed. Actually both breeds grazed more at midday during the summer than in the winter. In comparing results from other locations, there is no close relationship between grazing time and quality of forage per unit area. One of the major differences between breeds was that the Santa Gertrudis spent more time walking (12.1% versus 6. 5%), and traveled further (7. 8 miles versus 4. 9 miles), then the Herefords. When the number of defecations and urinations are compared with observations from other locations, and when a relationship with degree of forage maturity is assumed, the forage consumed yearlong was intermediate between dry, leached forage and succulent, green forage.
