| Sumario: |
Gastrointestinal nematodes are the most common parasites found in ruminants in the world. These parasites cause parasitic gastroenteritis and have a negative effect on productivity. Nematode control has been based on the use of anthelmintic chemicals—against which nematodes have developed a certain degree of resistance—which have been rated as residual substances in goat products that may cause adverse effects on the final consumer. As a result, the study of plant components has been proposed as a sustainable alternative to control nematodosis in goats. The anthelmintic potential of aqueous extracts of Nicotiana tabacum and oily extracts of Azadirachta indica on gastrointestinal nematodes affecting the goat chain was evaluated in vitro in this study. Nematicidal activity tests were performed on stool samples from goats with a high parasite load (trichostrongyles), by performing dose/ response curves. Percent inhibition in egg hatch for the aqueous extract of N. tabacum and the oily extract of A. indica was 99% and 80%, respectively. Extracts showed an effect on larva 3 (infective stage), with a mean lethal time of 8 ± 1 minutes for extracts of N. Tabacum, and of 8 ± 1 minutes for extract of A. indica. The in vitro results of the nematicidal activity show that N. tabacum and A. indica extracts can be a promising alternative for controlling nematodes in ruminants. |
