Three species of Desmanthus adapted to the heavy clay soils of northern Australia were
studied to determine their nutritive value and effects on in vitro fermentation with rumen fluid …

BACKGROUND In northern Australia, beef cattle grazed extensively on tropical rangelands
are responsible for 5% of the nation's total greenhouse gas emissions. Methane (CH4) is a …

Beef cattle production constitutes the main land use in the neotropical savannas of the
eastern Colombian Orinoquia. However, the effects of Brachiaria decumbens Stapf (Bd) …

The savannas of eastern Colombia located in the Orinoco river basin represent 18% of the
Latin American neotropical savannas, and those areas that are tillable and closer to markets …

Introduction Previous research has shown increased productivity amongst sown grass
pastures compared to native savanna pastures by year-round grazing for fattening of adult …

Cow–calf operations constitute the main land-use system in the 18 million ha of well drained
tropical savannas of Colombia located in the Orinoco basin. There, numerous sex and age …

Extensive, rangeland-based beef production systems that predominate in the neotropical
savannas of northern South America are low input-low output beef breeding systems, and …

ABSTRACT A substantial proportion of beef production in Colombia originates in its
extensive Eastern Plains. However, in this scenario and in a global context, demand for …

Replacement beef heifers in extensive systems of the neotropical savannas of Colombia are
low priority animals and are assigned to native savannas and low-quality pastures, with …

Objective This study was aimed at evaluating effects of cattle breed resources and
