Abstract

The worms in goats is an important factor causing considerable productivity losses, having as its main causes the incorrect management in the control of these worms on the part of farmers. Among the most frequent causes of this resistance we can highlight the absence of weighing the animals, use of incorrect dosages, indiscriminate use of the active ingredients; which causes the control of emergency measures worms are many times not efficient. Thus, this experiemntos was conducted in order to verify the parasitic resistance hornbeam trees in the state of Mato Grosso, three active ingredients commonly used. They were tested Levamisol Hydrochloride, Oxfendazole and Albendasol in three farms in the year 2014-2015. The Oxfendazol and Albendasol drugs were not effective and the hydrochloride Levamisol averaged 82% effective, but this value is already possible to notice that there is also some resistance to this active principle. The three assets valued principles can not be recommended to control worms in goats in the state of Mato Grosso.
