Produção de leite bubalino na microrregião do Arari arquipélago de Marajó, Pará: Caracterização e recursos forrageiros.

Abstract

The Marajó archipelago is nationally known for raising buffalo. That is evidenced by the large concentration of those animais there, which accounts for 38.19% of the existing buffalo in Brazil. And the main food component of the region, the native pastures, in their different habitats. This study aimed to characterize the milk production and native forage resources present in the microregion from Arari, in the Marajó Archipelago, Pará. At first were applied 40 questionnaires for the main buffalo milk producers from Arari microregion. Later, a botanical survey in 14 properties, seven in the municipality of Soure, and seven in Cachoeira do Arari. Where from each property samples were taken to establish the richness index of the identified species. The chemical composition of the species Echynochloa polysthachia and Colona, and the histochemical test of the median region of the central leaflet of leaves, where semipermanent slides were mounted to detect the presence of starch , total sugars, lipids and lignin.lt was observed that 67.5% of respondents said that food is the main constraint on the development of dairy farming, 80% produce milk for a few months of the year, 42.5% did not develop alternatives to improve their pastures. Among the native species Echynochloa polysthachia and Paspalum conjungatum had higher richness ratio in relation to other identified ones. For ali histochemical test results were positive for the polysthachia Echynochloa species and Colona. Thus, in the micro Arari there is a need to develop production systems that strengthen the rational use of native pastures, contributing to competitiveness of the livestock productivity allied with economic, social and environmental sustainability.
