Resumen

ROJAS GONZALEZ, Yunuen Socorro et al. Forage availability of three bushes in Reserva de la Biósfera Tehuacán-Cuicatlán. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.spe16, pp.3381-3390. ISSN 2007-0934.

In semiarid regions of Mexico the silvopastoral system with extensive use of trees, shrubs and herbaceous goats feeding practice. The purpose of this study was to determine the availability of foliage of Acacia subangulata, Lippia graveolens and Mascagnia parviflora. The 50 individuals of each species were selected and dry matter production, plant height (A), number of stems (N), crown diameter (D) and density of plants per hectare was quantified. Leaves and tender stems were collected at a maximum height of 1.8 m. A multivariate analysis correlating the dry matter production with A, N, D was performed, and prediction equations forage biomass (Y) were generated. Prediction equations were: Y= -33.74+0.008*(A*N*D) with R2= 0.87 for A. subangulata; Y= -15.31+(0.6097*D) with R2= 0.63 for L. graveolens; and = -36.05+(1.21*D) with R2= 0.63 for M. parviflora. It is concluded that it is possible to predict forage production from A, N, D using prediction equations with a moderately high reliability.

Palabras llave : correlation; forage biomass; prediction equations; silvopastoral system; goats.
