Resumo: | The purpose of this study was to evaluate the behavior of dairy calves bred in tropical climate. Six calves of the Girolando breed at 3 months old in average were used. For the elaboration of the ethogram, the focal animal sampling method was used for five days. The Analysis of Variance was run and treatment means were compared by Tukey’s test at 5% probability. Findings show that calves spent more time in the concentrate intake and foraging, the rumination occurred more frequently during the night, and no significant differences were found between the water intake and the leisure activity. The thermoregulation behavior regarding the shadow demand did not differ statistically when compared to the sun rays demand. However, animals remained in the standing position for longer in the afternoon, and spent more time walking in the morning. Statistical differences were found between the playing interaction 1 and the playing interaction 2, and there were no statistical differences between the stereotypy and vocalization. Therefore, the behavioral states were found to be indicators of the good welfare degree for calves kept in a tropical breeding system. |

Se utilizaron seis terneros Girolando con una edad promedio de tres meses. Los animales se observaron directamente (animal focal) durante cinco días y su comportamiento se registró en un etograma. Los datos se sometieron a análisis de varianza y las medias se compararon mediante la prueba de Tukey al 5% de probabilidad. A la vista de los análisis realizados, se observó que los terneros pasaban más tiempo en las actividades de ingestión de concentrado y forrajeo. Los animales rumiaban predominantemente por la noche. No se observaron diferencias estadísticas entre actividades acuáticas y de ocio. El comportamiento de termorregulación, evaluado mediante la búsqueda de sombra y sol, no difirió estadísticamente. Sin embargo, los animales permanecieron en posición de pie más tiempo durante la tarde. Los animales pasaron más tiempo caminando por la mañana. Hubo una diferencia estadística en el comportamiento de interacción de jugar 1 y tocar 2. No hubo diferencia estadística para las variables de estereotipo y vocalización. Se concluyó que los estados de comportamiento eran indicadores de un buen grado de bienestar, para los terneros mantenidos en un sistema tropical de crianza.Objetivou-se com esse estudo avaliar o comportamento de bezerros leiteiros criados em clima tropical. Foram utilizados seis bezerros da raça Girolando com idade média de três meses. Os animais foram observados de forma direta (animal focal) durante cinco dias e seus comportamentos foram registrados em etograma. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% de probabilidade. Diante das análises realizadas, observou-se que os bezerros passaram mais tempo nas atividades de ingestão de concentrado e forrageamento. Os animais realizaram ruminação predominantemente à noite. Não foram observadas diferenças estatísticas entre as atividades de ingestão de água e ócio. O comportamento de termorregulação, avaliado pela procura por sombra e sol não diferiram estatisticamente. No entanto, os animais permaneceram mais tempo na posição em pé durante o período da tarde. Os animais passaram mais tempo caminhando na parte da manhã. Houve diferença estatística no comportamento de interação brincar 1 e brincar 2. Não houve diferença estatística para as variáveis estereotipias e vocalização. Concluiu-se que os estados comportamentais foram indicadores de um grau de bem-estar bom, para os bezerros mantidos em sistema tropical de criação.Research, Society and Development2021-03-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1296510.33448/rsd-v10i3.12965Research, Society and Development; Vol. 10 No. 3; e26310312965Research, Society and Development; Vol. 10 Núm. 3; e26310312965Research, Society and Development; v. 10 n. 3; e263103129652525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/12965/12091Copyright (c) 2021 Dariane Fontes da Silva; Alberto Jefferson da Silva Macêdo; Amanda Silva de Lima; Anderson Antônio Ferreira da Silva; Maycon Souto Gomes; Eduardo Henrique Santos de Lima; Márcia das Neves Soares; Thaiano Iranildo de Sousa Silva; Vinícius de França Carvalho Fonsêca; Edilson Paes Saraivahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Dariane Fontes daMacêdo, Alberto Jefferson da SilvaLima, Amanda Silva deSilva, Anderson Antônio Ferreira daGomes, Maycon SoutoLima, Eduardo Henrique Santos deSoares, Márcia das Neves Silva, Thaiano Iranildo de SousaFonsêca, Vinícius de França Carvalho Saraiva, Edilson Paes2021-03-28T12:03:35Zoai:ojs.pkp.sfu.ca:article/12965Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:24.083762Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
