Factors associated with the prevalence of helminths in Mangalarga Marchador horses in southern of Minas Gerais, Brazil

Fatores associados com a prevalência de helmintos em cavalos da raça Mangalarga Marchador em propriedades do Sul de Minas Gerais

ABSTRACT:

Horses are highly susceptible to parasitism. Helminth infections cause great harm to the animals and to their breeders. This study aimed at evaluating socioeconomic, cultural and management factors associated with the prevalence of gastrointestinal helminths of horses. A total of 40 farmas the Mangalarga Marchador horse breed were visited in southern Minas Gerais, Brazil, where interviews were conducted. Horse feces were collected on the farms and coproparasitological laboratory tests were conducted to quantify the infection and to identify parasites. Data were tabulated in Epidata and analyzed using the SPSS 20.0 software. A great similarity between breeds was observed, specifically in their profiles, as well as in their animal management techniques and in their parasite control habits. The cyathostome was the most prevalent helminth, followed by Oxyuris and large strongyles. The farms which prioritize only equine production are less likely to have animals with massive helminth infection.
