Effects of neem pie on the alternative control of gastrointestinal nematodes in sheep: Review

Abstract

One of the main problems of sheep farming is the parasitism caused by gastrointestinal nematodes that causes great losses in the activity and that makes economic production unfeasible. For this reason, the use without technical criteria of chemical products becomes more frequent in the properties, thus contributing to the parasitic resistance. Due to this resistance created by parasites to synthetic anthelmintics, the need to seek new active principles effective in the control of endoparasites is well known, with phytotherapy being a sustainable alternative. In this context the use of plant extracts popularly known as neem (Azadiractha indica) containing insecticidal activity may become a viable alternative in the fight against gastrointestinal nematodes. Therefore, the purpose of this paper is to review the literature on the possible potential of the use of neem pie (Azadiractha indica) as an alternative source for the control of endoparasites in sheep farming, minimizing the use of synthetic chemicals that are harmful to the environment.
