Avaliação de bem-estar em vitelos leiteiros

Abstract

Com a presente dissertação pretendeu-se desenvolver um protocolo de bem estar para vitelos de aptidão leiteira. Tendo como objetivo estabelecer um sistema de avaliação de bem-estar para vitelos de aptidão leiteira analisando diferentes indicadores. Desta forma, foi elaborado um questionário divido em quatro parâmetros de avaliação distintos: parto, alojamento, nutrição e saúde. Para cada critério avaliado existia uma pontuação associada e, por fim, uma pontuação final de bem-estar da exploração avaliada. O estudo incluiu vitelos fêmeas e machos, desde o nascimento até ao período de desmame (aproximadamente 12 a 14 semanas), nascidos entre julho de 2023 e fevereiro de 2024. Um total de 421 vitelos (141 machos e 280 fêmeas) foram incluídos no estudo, tendo sido avaliadas um total de 20 explorações. Das explorações estudadas, nenhuma atingiu o grau de excelência, assim como nenhuma foi classificada como "não classificada" ou "básica", sendo assim classificadas como "suficiente" ou "bom". A pontuação obtida pelo protocolo foi relacionada com a taxa de mortalidade dos vitelos, sendo possível concluir que as duas variáveis não são facilmente relacionáveis, não existindo uma correlação significativa entre as duas.

This study aimed to develop a welfare protocol for dairy calves. Aiming to establish a welfare assessment system for dairy calves by analyzing different indicators. To this end, a questionnaire was developed, divided into four distinct assessment parameters: birth, housing, nutrition, and health. Each evaluated criterion had an associated score, culminating in a final welfare score for the evaluated farm. The study included both female and male calves, from birth to the weaning period (approximately 12 to 14 weeks), born between July 2023 and February 2024. A total of 421 calves (141 males and 280 females) were included in the study, covering 20 farms in total. Among the studied farms, none reached the level of excellence, nor were any classified as "not classified" or "basic." Instead, they were categorized as either "sufficient" or "good." The score obtained by the protocol was compared to the mortality rate of the calves. It was found that the two variables are not easily relatable, with no significant correlation identified between them.
