Epidemiología de la tricostrongilidosis de los rumiantes en praderas de regadío

Abstract

The grazing livestock exploitation system is the one that most closely resembles the natural living conditions of the species and, in such circumstances, parasite-host relationships are favored. This is the reason why ruminants, when exploited in a traditional way, are considered the domestic species most affected by parasites and therefore it is not surprising that the sheep species, throughout its evolution, has reached serve as a host for about 200 different species of parasites (TARAZONA, 1980).
