RUBILAR, L. et al. Anthelmintic efficacy of three endectocides administered by oral route in horses. Arch. med. vet. [online]. 2001, vol.33, n.1, pp. 69-75. ISSN 0301-732X. http://dx.doi.org/10.4067/S0301-732X2001000100008.
In naturally gastrointestinal nematodes infected horses the anthelmintic efficacy of the endectocides ivermectin (IVM), doramectin (DRM) and moxidectin (MXD) was evaluated. Animals were evenly distributed to 4 experimental groups: Group I, non treated horses, control; Group II treated with an oral dose of 0.2 mg/kg of IVM by oral route; Group III treated with a reformulated oral dose of 0,2 mg/kg of DRM; Group IV treated with an oral dose of 0.4 mg/kg of MXD. Faecal samples for parasites eggs count and larval cultures were collected before treatment at 3,6,10,20,40,60,90,105,125,145 and 175 days postreatment. Results obtained showed a significant reduction (p <0,05) in the faecal eggs count in treated group, from day 3 to day 145 post treatment. This level of significance remained until day 175 post treatment only in the group treated with moxidectin
