Abstract(s)
A agalaxia contagiosa é uma micoplasmose que afeta pequenos ruminantes e causa mastites, aga- laxia, poliartrites, queratoconjutivites e, ocasionalmente, aborto e pneumonia.
Para melhor compreender a epidemiologia, a prevenção e o controlo da agalaxia contagiosa no distrito de Bragança, foi realizado, entre janeiro de 2020 e dezembro de 2021, um estudo transversal com o objetivo de estimar a ocorrência da doença em ovinos e caprinos. Foi aplicado um questionário epidemiológico a 108 rebanhos. A análise das variáveis foi realizada pelo método do qui-quadrado. Um nível de significância de p<0,05 foi considerado estatisticamente significativo. Neste estudo, 28,7% dos rebanhos estudados relataram diagnóstico prévio de agalaxia contagiosa. A ocorrência foi superior nos rebanhos de caprinos (71,4%) (p<0,000). Foram registados resultados mais elevados em rebanhos de aptidão mista (58,6%; p<0,000) e em sistemas de produção intensivos (80%; p=0,009). A ocorrência foi superior nos rebanhos onde os produtores tinham formação em produção pecuária (45,8%; p=0,041).
Os resultados encontrados neste estudo corroboram as recomendações atuais para o controlo da agalaxia contagiosa em pequenos ruminantes. As ações de formação junto dos produtores devem incluir conteúdos que permitam melhorar o conhecimento da doença e o maneio das explorações de forma a permitir uma prevenção e controlo da doença mais eficaz.
Contagious agalactia is a mycoplasmosis of small ruminants that causes mastitis, agalactia, polyar- thritis, keratoconjunctivitis and, occasionally, abortion and pneumonia. To better understand the epidemiology and the prevention and control of contagious agalactia in Bra- gança district, a cross-sectional study was conducted to estimate the occurrence of the disease in sheep and goats from january 2020 to december 2021. An epidemiological questionnaire was applied to 108 flocks. The analysis of variables was performed using the chi-square method. A significance level of p<0.05 was considered to be statistically significant. In this study, 28.7% of the flocks under study reported a previous diagnosis of contagious agalactia. The occurrence was higher in goat flocks (71.4%) (p<0.000). The occurrence was higher in mixed aptitude (58.6%; p<0.000) and in intensive production systems (80%; p=0.009). Surprisingly, the occurrence was higher in flocks were farmers had training in livestock produc- tion (45.8%; p=0.041). The results found in this study support current recommendations for the control of contagious agalactia in small ruminants. Special attention should be given to the assessment of the type of training and skills acquired in the management of farms in the prevention and control of the disease.
