Mortalidade perinatal em pequenos ruminantes em Trás-os-Montes
Mendonça, Álvaro; Valentim, Ramiro; Correia, Teresa Montenegro; Quintas, Hélder; Grau, Ana; Monteiro, M.Nas explorações de Pequenos Ruminantes de Trás-os-Montes, a mortalidade perinatal é responsável por baixas significativas na produtividade e na viabilidade económica das mesmas. Dadas as características edafoclimáticas locais, a Produção Ovina e Caprina tem uma grande importância social, económica e ambiental, o que confere a qualquer investigação neste sector uma importância vital. Com este estudo pretendeu-se...
