Potential of the Oregano as natural alternative to control Haemonchus contortus in hair ovines
Main Article Content
Abstract
With the aim of evaluating the potential of oregano in reducing the load of eggs of Haemonchus contortus in haired sheeps (n= 15), homogeneous in age (8 to 12 months), received an oral dose of 4,500 infective larvae (L3) of H. contortus. Five animals were randomly assigned to one of three groups to receive: 1). Grinded oregano (GRD), 2). Levamisole (LEV) as gold-test and a 3). Control group was considered, which received no treatment against the parasite. At 19 days of evaluation, the GRD reduced 64.9% (P <0.05) the load of eggs. As conclusion, a single dose of grinded oregano shows potentially as natural alternative to control H. contortus in haired sheeps raised at the northwest of Mexico.
