Quantifying botanical composition is important for evaluating the effects of management on legume content and of legume content on pasture yield and quality. The standard for measuring botanical composition is hand separation of clipped samples. An alternative is taking point counts of botanical components on photographs of the pasture. The latter was tested on a rotationally stocked pasture, w...

In order to study the effect of grazing pastures with a different botanical composition on rumen and intramuscular fatty acid metabolism, 21 male lambs were assigned to three botanically different pastures: botanically diverse (BD) (consisting for 65% of a variety of grass species); Leguminosa rich (L) (consisting for 61% of Leguminosae) and intensive English ryegrass (IR) (with 69% Lolium pere...

A critical dimension of global environmental change is the high rate of deforestation taking place as landholders convert primary and secondary growth into pastures for raising cattle. In the Brazilian Amazon, the expansion of cattle ranching is occurring at such a rapid pace that concerned analysts have coined the term "pecuarização" (cattlelization) to depict the extraordinary increase in the...
