Seven perennial species of African origin-Brachiaria arrecta, B. brizantha, B. decumbens, B. dictyoneura, B. humidicola, B. mutica, and B. ruziziensis-have been used as fodder plants, particularly in tropical America. The history of the commercial cultivars is given, and their most important attr...

The production of tropical pasture species is determined by a complex of interacting factors which include the climatic variables of temperature, rainfall, and solar radiation; the soil's capacity to supply nutrients; the soil water available to the roots; and the effects of both current and prev...

Book Chapter 1993

Autor: Tergas, Luis Eduardo

The factors of grazing management that influence tropical pasture utilization are discussed in this review. The principal objective is to consider stocking rate and grazing system effects-and their interaction-as related to the evaluation of germplasm under grazing. It is inferred that the study ...

Autor: Hodgson, John

Variations in sward canopy structure can exert an important influence on the ingestive behavior of grazing animals and hence on herbage intake and utilization. In tropical swards, the structural characteristics of major importance appear to be total herbage density or leaf bulk density and leaf-t...

The evaluation of pasture plants is complicated by the fact that no absolute yield exists with which experimental results can be compared. Evaluation techniques should therefore simulate as far as possible the conditions to be encountered on commercial farms, thus suggesting that modifications to...
