Poor nutrition because of poor quality feeds and fluctuating feed supply is a major constraint to tropical livestock productivity. The need to supply greater quantities of quality fodder requires development of both new forages and feeding strategies that will enhance the efficiency with which co...

The genus Stylosanthes contains about 30 species of which most are native to South and Central America, except for S. erecta and S. fruticosa which are native to Africa. The seven major species that have been used as livestock feed have been widely collected and their germplasm stored in genebank...

Conservation of germplasm has traditionally relied to a large extent on storage of seeds in genebanks. However, some forage species may take a long time to research maturity and produce seeds or, in the case of grasses, have inadequate production of seeds for collection, multiplication, dissemina...

Autor: Keller-Grein, Gerhard Maass, Brigitte L. Hanson, Jean

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, particulary in tropical America. The history of the commercial cultivars is given, and their most important a...
