Characterization of the genotypk variation in the chemical composition and digestibility of Trichanthem gigantea (H. B.) Nees.

摘要

In the past few years, the development and implementation of economical alternatives of animal feeding has advanced toward the study and valuation of the local forage. This is the case of Nacedero Trichanthera gigantea, fodder trees specie that has contributed to enlarge the nutritional offer of different animal species, mainly monogastric, where it was noticed a variability in the evaluation with animals. To establish if the phenotypic variation observed was fundamentally of genetic origin (by effect of provenance), to give a environment or product of interaction genotype -environment, CIPAV established a bank of provenances of the specie with representative species obtained in Colombia and Venezuela (Resales, 1998).
