Animal Welfare (BEA) is a practice that is in great evidence today and that began to be applied in the 60s, through the dissemination of the book Animals Machines, by Ruth Harrison and formation of the Brambell committee, in the United Kingdom United. The purpose of the publication was to sensitize readers and the population to a less anthropocentric view of animal production, through the proclamation of proven information that animals of other species are sentient beings, and that domestication is a transformative attitude capable of modifying , intrinsically, its genome with direct result in the production chain. In livestock farming, raising dairy heifers is of great importance for world production and the country's economy, as it is the area of agribusiness that employs the most and grows in Brazil, and therefore, careful care in the first hours after birth and throughout the period of breastfeeding are essential for a healthy physical development of these animals, as well as an adequate behavioral response for the species with an excellent economic result.
