During 74 days, three groups of six Nelore weaned heifers, with natural mixing infections of gastro-intestinal nematodes, were housed separately and treated with 20, 10 and 0g animal-1 day-1 of dehydrated garlic added the ration. During all the experimental period no statistical difference (P>0.05) between treated and control groups was observed in egg per gram of faeces (EPG) and in relative percentage of infective larvae in the larval cultures.
