Geographical distribution of zebu breeds and their relationship with environmental variables and the human development index

The environment is vital to the agricultural sector since it can cause adversities throughout entire productive chain. This study evaluated geographical distribution of zebu breeds in Brazil and correlated their occurrence with environmental variables human development index. Herds purebred cattle (Bos indicus) were classified as beef, dairy, dual-purpose breeds, all spatialized ArcGIS program. Environmental (precipitation, temperature, relative humidity index) index (HDI) examined. We conducted regression logistic analyses. Zebu showed a lower Northeastern states compared other locations, possibly due harsh weather conditions, namely long periods high temperatures precipitation, directly affecting local livestock. Beef evenly spread country regions influenced by higher normalized difference vegetation (NDVI), (RH), temperature (THI), well properties without smallholder farmers rivers streams riparian vegetation. for dairy predominantly cultivated cutting forages (e.g., sugarcane - Saccharum officinarum), integration crops, livestock and/or forestry (i.e., combining different activities same area) areas rotational grazing system management), indicating occupation fertile lands. Gir breed, only breed this study, was seen establishments farmers, characterized small medium farms, at altitudes.
