Zonificación bioclimática para la producción de ganado lechero en la región sureste de la Amazonía Legal

Abstract

Bioclimatic zoning for dairy cattle production in the southeast region of the Legal AmazonAbstract. This study intended to establish the bioclimatic zoning of the southeast state of Pará aiming at the production of dairy cows. For the realization of bioclimatic zoning, data from the years 1992 to 2017 were collected from conventional meteorological stations under the responsibility of the National Meteorological Institute (INMET) that comprise the Southeast region of Pará. With the data observed in this study, it is possible to affirm that the climatic conditions of the studied region are not ideal for the production of animals of the Jersey, Holstein and Girolando breeds, presenting constant high temperature and relative humidity and with the temperature and humidity index (THI) above 78. Thus, we reinforce the need to use environmental changes in the productive farms of the region. We also encourage studies that aim to understand the adaptive strategies of dairy cattle under thermal stress conditions.
