Thermal comfort analysis and its influence on the production and quality of milk in the cerrado domain environment

Abstract

There are many factors that contribute to the increased effects of thermal stress such as productivity, breed and breeding system. In this sense, the purpose of this study was to evaluate the effects of thermal stress on milk production and composition, from May to September 2017, all of which were collected after milking at in a non-invasive way to the welfare of the animal. The data were collected through the use of a digital thermometer and the milk test for milk composition performed at the Milk Quality Laboratory (LQL) of the Federal University of Goiás (UFG) in Goiânia. After tabulation of the data, the treatments with the contents of solids found in the milk and productivity of the matrices that were part of the experiment were compared, where no significant difference was found in the evaluated treatments, showing that the promotion of animal welfare and of extreme importance for increase and quality of milk production.
