Six fodder tree species （Leucaena, Leucaenaleucocephala, Morera, Morus alba, Chacloco, rubiHamelia patents, Guficima, Guasumaulmifolia, Pichoco-bunting, Erythrinaamericana, Cocuite, Gliricidiasepium） were selected for their leave production, rapid growth and high nutritional quality. The plants were evaluated in the bud stage of senescence and flowering, restricting the fraction of mature foliage in the samples located under 2 meters height. Samples were collected from five plants per specie that were randomly selected. The nutritious parameters were evaluated through proximate analysis with the Van Soest technique. This study used a completely randomized design with five replicates. The nutritious composition showed PC （protein content） differences （P 〈 0.05） among species indicating that Leucaenaleucocephala （20%） had the lowest, Gliricidiasepium was （21%） intermediate and Morus alba （23%） had the highest. The FDN （neutral detergent fiber） and FDA （acid detergent） were lowest for Guasumaulmifolia （23.4%） and the other five species exceeded 40%. In conclusion, native foliage of fodder trees in northern, Veracruz are highly nutritious for cattle feeding and could alternative to avoid deforestation for pasture establishment to continue.展开更多
