The studies on introduction of improved grasses in association with leguminous trees in the crop-livestock production at small scale holders for feeding cattle was carried out in Thainguyen Province in a period of two years (2003-2004). The design of Pasture in Small Farmers (1996) and Participatory Agricultural Extension Methodology (PAEM, 2003) were used for conducting the studies. The improved pastures introduced were Paspalum atratum, P. Purpurseum, P.M. TD58, Brachiara decumben, Brachiaria brizantha, Brachiaria muntica, Guatemala and leguminous plants such as Leucaena leucocephala, Flemingia macrophyla and Trichantera gigantean. After 2 year conducting studies, the results showed that: The improved grasses as Paspalum atratum, P. Purpurseum, P.M. TD58, Brachiara decumben, Brachiaria brizantha, Brachiaria muntica, Guatemala and some legumeinous plants and high protein content such as Leucaena leucocephala, Flemingia macrophyla and Trichantera gigantean gave high edible yields. Especially in practices of intensive farming system the edible yield from 40-56 tones dry matter (DM)/ha/year were obtained; The varieties of Paspalum atratum, P.M. TD58 adapted well under shade of fruit trees at a period of 1-5 years old and also so gave high edible yield (27-37 tones DM/ha/year); The legume plants such as Leucaena leucocephala, Flemingia macrophyla and muti-purpose trees Trichantera gigantean was suitably planted as hedgerow in the fruit trees at 1-5 years old and they gave the edible yield of 6 tones DM/ha/year and contributing 10 percent of the total edible biomass yield of pasture. The ratio of legume foliage supplied for cattle have contributed to increase an amount of 20g Protein/kg DM of roughage in daily diet of the cattle.
