ResumoThe most widespread animal production system is grazing and systems are slightly intensified (Devendra and Mc Leroy, 1982;CIAT, 1985;Osuji, 1987).The SR production systems are based on natural savannas, leading to poor animal performances.With regard to tropical forages the following facts have been well documented (Humphreys, 1991): tropical pastures are productive but season-dependent, their high content of structural elements, that are poorly digestible, lead to low or medium nutritive values (Aumont et al., 1995).However, adequate management of tropical pastures at the right stage of maturity may lead to a better nutritive value.The intensive utilization of forages is one way of increasing the production of ruminants in tropical areas using semiintensive management systems which may increase production from pastures where land and energy-dense feeds are limited [CIAT (1985) and Osuji (1987) for Latin-American regions and Kochapakdee et al. (1994), Humphreys (1991) and Corbett (2001) for Asian-Australasian regions].In the French West Indies intensive grazing systems (artificial pastures, high level of fertilisation and irrigation)
