The aim of this study was to report and morphologically describe two small intestinal nematode genera present in cattle and sheep from Tabasco, Mexico. The specimens studied were obtained from animals for slaughter on a trail, cleared in Amann's lactophenol and their measurements were recorded using a calibrated ocular micrometer. Based on their morphologic characteristics, three species were identified: Cooperia curticei, Cooperia punctata and Trichostrongylus colubriformis. In C. curticei, the length of the tail-vulva was higher (1726.9± 194.4 mm) than in C. punctata (1422.1±151.7 mm); and the vulva shape of C. curticei was flat, while in C. punctata, it was botonous. In Cooperia males, the spicule lengths were similar in both species (139±13 mm). The...

Abstract Horn fly (Haematobia irritans) is a widespread external parasite of grazing cattle; and integration of alternative biological control of this pest could help reduce the risk of resistance to chemical control. The objective of this experiment was to determine skin reaction to horn fly load on grazing dairy cattle sprayed with a 20 % creosote bush (Larrea tridentata (DC.) Coville) leaf extracts solution. To evaluate skin reaction a 10-month heifer with six paired circles marked on her skin was used, five sprays at five-day interval were applied; response variables were any harmful effect on skin and hair. To evaluate horn fly load effects there were two treatments: spraying or not of a 20 % creosote bush leaf extract, with six and seven cows for the...
