CARDONA A, José A; VARGAS V, Marlene I  y  PAREDES H, Enrique. Frequency of Gastric Pathologies In Horses (Equus caballus) Slaughtered in an Abattoir of Temuco, Chile. Rev. Fac. Cienc. Vet. [online]. 2015, vol.56, n.2, pp.105-109. ISSN 0258-6576.

The aim of the present study was to determine the frequency of gastric pathologies in horses (Equus caballus) slaughtered in a refrigerated abattoir of Temuco (IX Region), Chile. A total of 240 stomachs of 130 males (34 non-castrated and 96 castrated) and 110 females were assessed. The age of the horses ranged between 3 and 16 years. The stomachs were evaluated, characterized, and photographed post mortem. The data on sex, age, and pathology were filled out in their respective formats and subsequently digitized. Of the total population (240 stomachs), some kind of pathology was found in 100% of the samples, of which 95% had gastric ulceration (87.5% located in the squamous area of the mucosa; 47.9% in the glandular mucosa; and 45.8% in both areas). 64.6% of the stomachs showed chronic gastritis and 36.3% acute gastritis. In 60.4% of the stomachs cavitary myiasis (Gasterophilus spp.) was detected and 17.5% were infected with Trichostrongylus axei. The study demonstrated a statistically significant dependence (P<0.05) between age and severity of gastric ulcers. It is concluded that there is a high incidence of gastric pathologies in horses slaughtered in southern Chile, being the squamous ulcers, the most frequent, followed by chronic gastritis and cavitary myiasis. Therefore, it is necessary to perform more research and be aware of the management of these diseases in these animals.
