Vocalización como marcador de estrés en ganado bovino

Abstract

The increase in the number of bovines makes it difficult for the farmer to observe and monitor animals individually, an eventinfluenced by the emotional health of the animal. At the same time, current consumers of bovine products and by-products demand morecontrol and information about the welfare during their production. Different methodologies were described to control and measure animalwelfare. Vocalization or vocal expression of the animal can be measured and translated into positive and negative emotional levels that serveas markers or indicators of stress that afflicts this particular species. The aim of this review was to describe the events that influence in cattle-stress linked to methods of identification by vocal expression. The use of vocalizations as an indicator of stress to assess the well-beingof cattle has been constantly discussed, however, the dynamic emotional content manifested by vocalization or levels of vocal expressionshould be further studied. Interestingly, it could be predicted and therefore we might provide a positive emotional state influencing theproduction and well-being of the animals.
