LEZCANO-MAS, Yohanka et al. Tithonia diversifolia forage for the control of gastrointestinal strongyles in young cattle. Pastos y Forrajes [online]. 2016, vol.39, n.2, pp. 133-138. ISSN 2078-8452.

A study was conducted in order to determine the effect of the inclusion of Tithonia diversifolia (tree marigold) forage on the control of the infestation by gastrointestinal strongyles in grazing young cattle, in the rainy (RS) and dry season (DS). The experimental design was completely randomized, with two treatments (tree marigold and supplementation with concentrate feed) and four repetitions in time. The evaluated indicators were: parasite rate (FEC) of gastrointestinal strongyles, protein percentage and phytochemical composition of the foliage. A significant effect was observed on the reduction of the parasite rate of the animals which consumed tree marigold forage (150 and 450 epg for the DS and RS, respectively), with regards to those of the control group, whose values exceeded 500 and 3 500 epg, respectively. It is concluded that the protein content and the presence of secondary metabolites contributed to the decrease of the parasite rate, for which tree marigold can be a forage plant with potential for ruminant production.
