SIMON, L  and  GALLOSO, M. Evaluation of the productive performance of river buffaloes in system with trees and grass monocrop . Pastos y Forrajes [online]. 2008, vol.31, n.2, pp.1-1. ISSN 0864-0394.

The effect of trees on the rearing of river buffaloes was studied in two units or farms with 30 dairy cows each and their calves, and the technology of rational silvopastoral system with Leucaena leucocephala was compared to a grass monocrop. An initial diagnosis was carried out to learn the characteristics of each unit and the floristic composition of the areas. The dry matter availability of the pastures was determined monthly in order to regulate the stocking rate in the pastureland and during four consecutive years the productive and reproductive indicators, as well as the economic incomes, were measured. The results in the tree system were higher in 0,72 kg of milk per cow per day; 279,8 kg/lactation; 1,49 kg/ha/day and 42 more days of lactation; nevertheless, the most significant aspect turned out to be the daily milk production per hectare in the system with trees, which tripled that of the grass monocrop (2,24 vs 0,75 kg), as a consequence of a higher availability of dry matter and nutrients. This allowed to increase the stocking rate, which was reflected positively on the incomes for the milk sale. All the indicators analyzed favored the system of leucaena with the technology of rational silvopastoral system.
