Under the studied conditions, the structure and composition of community of parasitic nematodes observed in both sheeps and goats, is similar (r**s = 0,90 P <= 0,05 y C**ss = 93,33%), the Shannon-Weaver index of diversity was 1.23 more or less 0.15 bits and 1.15 more or less 0.24 bits for sheeps and goats, respectively. The equitability index resulted in 0.49 more or less 0.06 for sheep-nematodes and 0.44 more or less 0.09 for goats-nematodes. However, no significant difference was observed when the means of these indexes, were compared. Not withstanding, a greater homogenity was observed in the ovine parasitic nematodes.
