Resumo
A caquexia é uma síndrome metabólica complexa, caracterizada por perda de massa muscular e adiposa, conduzindo à inviabilização económica dos animais afetados.
Este estudo teve como objetivos a determinação da taxa de mortalidade associada à caquexia em leitões de recria, a caracterização das lesões macroscópicas observadas nas suas necropsias e a determinação de se estas permitiam estabelecer a sua etiologia.
O estudo decorreu numa exploração em Sesimbra, tendo como amostragem 7054 leitões de recria e as mortes verificadas neste universo. Como método de avaliação da caquexia recorreu-se a critérios clínicos pré definidos observados nos leitões de recria em vida e à classificação, por normas pré determinadas, dos achados das suas necropsias.
A taxa de mortalidade apurada por caquexia foi de 1%, sendo a taxa de mortalidade proporcional por caquexia de 62%. Dos 48 leitões necropsiados, 25 tinham enterite, 8 broncopneumonia, 6 polisserosite (doença de Glasser), 3 tromboembolismo pulmonar e 1 cardiopatia congénita. Permaneceram 5 leitões só com evidência clínica associada à caquexia, o que levantou a hipótese destes animais terem PFTS.
Concluiu-se que a necropsia pode não determinar a etiologia definitiva da caquexia, mas direciona o raciocínio clínico e os exames complementares de diagnóstico que possam estabelecer o diagnóstico definitivo.
Cachexia is a complex metabolic syndrome characterized by loss of muscle mass and body fat, leading to economic unfeasibility of affected animals. This study aimed to determine the mortality rate associated with cachexia in piglets, characterization of the associated gross lesions and determine whether those allow the establishment of the underlying cause. The study took place in a farm in Sesimbra, with 7054 piglets. A pre-defined clinical criteria to determine cachexia as well as the classification of the necropsy findings were used as a method of evaluation of cachexia in this study. The mortality rate associated to cachexia was 1%, while the proportional mortality rate of cachexia was 62%. Of the 48 piglets, 25 had enteritis, 8 bronchopneumonia, 6 polyserositis (Glasser's disease), 3 pulmonary embolisms and 1 congenital heart disease. Five piglets didn’t present macroscopic lesions which raised the possibility of having PFTS. It was concluded that the necropsy could not determine the definitive aetiology of cachexia, nevertheless it can direct the clinical reasoning and diagnostic exams that can establish a definitive diagnosis.
