Dairy Production of ‘Saanen’ Goats Based on Meteorological Variables and Future Climate Scenarios

Abstract

This study aimed to modeling and bioclimatic zoning of 'Saanen' goat milk production in northeastern Brazil. Data were obtained from a 14-year dairy control program for 246 'Saanen' goat matrices. Dairy production meteorological influence and mathematical modeling were assessed through statistical analyses such as Pearson's correlation matrix and path analysis. Bioclimatic zoning for current and future scenarios, with climate changes, were delineated using inverse-square distance (ISD) and spherical model (kriging) interpolations. Results showed maximum air temperature to contribute substantially to goat dairy production; therefore, its modeling was based thereon. Current and future dairy production maps highlighted Maranhão and Piauí as regions of limited 'Saanen' milk production. Furthermore, we should emphasize that temperature rises in further scenarios may have significant impact on the potential of dairy farming for the region under study.

Bioclimatic zoning for quails in the rain season in the state of Paraíba, Brazil

“…Bioclimatic zoning is developed in order to maximize the production of broiler chickens (Oliveira et al 2019), goats (Pequeno et al 2017) and cattle (Tavares et al 2016). However, some limitations can be found in mappings such as the absence of complete historical climatic data series and a reduced number of studies on the theme in several Brazilian locations (Amorim et al 2017).…”

The increase in blood ow in the body surface facilitates the exchange of heat by the animal through sensible mechanisms(Pequeno et al 2017, Torres et al 2017, Amorim et al 2019.At high ambient temperatures, the body core temperature ows to the body surface and to the limbs of the animals, in the opposite situation, the skin temperature gradients extend along the limbs, and the central temperature is restricted to the trunk and head(Medeiros et al. 2015, Silva et al 2019).…”
