Abstract

The helmintiasis occupy prominence place among the factors that limit goat production and your control has been accomplished, through the indiscriminate use of antihelminthic favoring development of antihelminthic drug resistance. The effectiveness of plants, são (Momordica charantia) caetano melon, (Operculina hamiltonii) purgative potato and (Curcubita pepo L) pumpkin seed and of the alcoholic são caetano melon extracts and of purgative potato; and of (Calotropis procera) silk flower essential oil was evaluated, about goats natural helminths infections. Forty moxotó males goats with age being six and 12 months were used, divided in four groups, three corresponding to each treatment and a group control, for each experiment.

For the essential oil of silk flower group the percentile was 37, 57% postreatment 60 days. The results indicated this plants and studied extracts, can be used as alternative in goats helmintosis gastrintestinais control, promoting like this, a viable ecologic control.
