Resumo: | Modern swine production faces many challenges nowadays, among which are productivity growth, meat quality improvement, decrease of environmental damage and reduction of cost production. Pigs spend energy to vocalizing, especially when they undergo stress. The waste of energy can increase the cost of production and lead to greater environmental damage. The goal of this study was to estimate the energy spent by pigs under the stress of castration and its effect on the animals' weight gain. Two groups of ten animals each were castrated, being one group with local anesthetic and the other without anesthetic. The piglets' vocalizations were recorded during different stages of the neutering process and then estimated of the amount of energy emitted during each vocalization. Afterwards, this energy was associated with the animals' weight gain. There was no difference in the total energy spent in both groups, since the energy used during the application of anesthetic was similar to the energy spent during the castration of the animals without anesthetic. There was also no correlation between energy spent and the animals' weight gain. It was possible to estimate the amount of energy emitted through vocalization. This energy spent by piglets in pain was greater than in other handling situations (contention, weighting and realease). |

Suínos gastam energia na vocalização, especialmente quando submetidos a determinado estresse. O desperdício de energia pode aumentar o custo de produção e conduzir a um maior dano ambiental. O objetivo deste estudo foi estimar a energia gasta pelos leitões sob o estresse da castração e seu efeito sobre o ganho de peso dos animais. Dois grupos de dez animais cada foram castrados, sendo um grupo com anestesia local e outro sem anestesia. As vocalizações dos leitões foram gravadas durante as diferentes fases do processo de castração, sendo objeto de uma estimativa da quantidade de energia emitida durante cada vocalização. Posteriormente, esta energia foi associada com o ganho de peso dos animais. Não houve diferença no gasto total da energia em ambos os grupos, uma vez que a energia utilizada durante a aplicação da anestesia foi semelhante à energia gasta durante a castração dos animais sem anestesia. Também não houve correlação entre a energia gasta e o ganho de peso dos animais. Foi possível estimar a quantidade de energia emitida através de vocalização. Esta energia gasta por leitões com dor foi maior do que em outras situações de manejo (contenção, pesagem e soltura).Associação Brasileira de Engenharia Agrícola2016-08-25T11:44:28Z2016-08-25T11:44:28Z2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCORDEIRO, A.
