Since these two parameters are essential for the optimal expression of their potential in feedlot, the association “Producteurs des bovins du Québec” (PBQ) requested the expertise of the Faculty of Veterinary Medicine (FMV) research team. Objective: The study highlights the most common calves rearing practices implemented in farms aiming the production calves with greater valuation in the Québec heavy veal industry. The objective is to identify and highlight the critical factors and good practices that ensure the production of high-quality calves for the general adoption of better long-term management (on animal health and welfare). Materials and methods: A total of 166 questionnaires were constructed and applied to Québec producers. Each questionary is composed by 56 questions covering selected parameters namely Calf management at birth, Nutrition and Housing management, in accordance with the priority stated by the producers questioned. Other parameters were also evaluated in this review such as producer background, farm general profile, biosecurity practices, calving management and conditions of departure to auction that remain in the Appendix for academic purpose. The results are based on the statistical analysis, under the form of a descriptive analyse realized with the software R studio (Version 2022.07.2+576), of the 56 questions. Results: The most important priorities for the producers were colostrum management (40,6%), housing management (25,1%) and milk nutrition (11,1%). As an example, when questioning the colostrum management more specifically, it turned out that 19,88% of the producers are respecting the literature standards but 5,42% of the producers make distinctions between replacement calves and calves for auction, subjects of our study. The results denote an under-valorisation of calves for auction and the questionnaires show a wish to find solutions to alleviate this lack of consideration. Future work: The continuation of the project will consist of developing a list of approximately 25 farms from the 166 farms requested in the questionnaire, to be contacted and visited for field data collection and will include the verification of the reliability of the results obtained on this report. |

Esta seria a principal razão pela qual os produtores de leite estão a limitar os seus esforços de valorização, o que reverbera sobre a saúde e bem-estar dos vitelos. Uma vez que estes dois parâmetros são essenciais para a expressão óptima do seu potencial em termos de confinamento, a associação "Producteurs des bovins du Québec" (PBQ) solicitou a especialização da equipa de investigação da Faculdade de Medicina Veterinária (FMV). O estudo destaca as práticas de criação de vitelos mais comuns implementadas nas explorações agrícolas, visando os vitelos de produção com maior valorização na indústria de vitelos pesados do Quebeque. O objectivo é identificar e destacar os factores críticos e as boas práticas que asseguram a produção de vitelos de alta qualidade para a adopção geral de uma melhor gestão a longo prazo (sobre saúde e bem-estar animal). Um total de 166 questionários foram construídos e aplicados aos produtores do Quebeque. Cada questionário é composto por 56 perguntas que abrangem parâmetros seleccionados, nomeadamente a gestão de vitelos à nascença, a Nutrição e a Gestão de Alojamento, de acordo com a prioridade declarada pelos produtores inquiridos. Outros parâmetros foram também avaliados nesta revisão, tais como antecedentes dos produtores, perfil geral da exploração agrícola, práticas de biossegurança, gestão de parto e condições de partida para leilão que permanecem no Apêndice para fins académicos. Os resultados baseiam-se na análise estatística, sob a forma de uma análise descritiva realizada com o software R studio (Versão 2022.07.2+576), das 56 perguntas. As prioridades mais importantes para os produtores foram a gestão do colostro (40,6%), a gestão da habitação (25,1%) e a nutrição do leite (11,1%). Como exemplo, ao questionar a gestão do colostro mais especificamente, verificou-se que 19,88% dos produtores estão a respeitar as normas da literatura, mas 5,42% dos produtores fazem distinção entre bezerros de substituição e bezerros para leilão, temas do nosso estudo. Os resultados denotam uma sub-valorização dos vitelos para leilão e os questionários mostram um desejo de encontrar soluções para aliviar esta falta de consideração. A continuação do projecto consistirá no desenvolvimento de uma lista de aproximadamente 25 explorações das 166 explorações pedidas no questionário, a serem contactadas e visitadas para recolha de dados de campo e incluirá a verificação da fiabilidade dos resultados obtidos neste relatório.Lopes, Professora Doutora Ana Isabel CaladoMartins, Professora Doutora Elisabete GomesRobichaud, Professora Doutora Marianne VillettazRepositório ComumRupek, Margot Karine Jacqueline2023-09-01T16:11:08Z2023-04-112023-04-11T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.26/46357TID:203343506engmetadata only accessinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-09-08T10:15:22Zoai:comum.rcaap.pt:10400.26/46357Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T20:28:32.246901Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
