Resumen

The objective of this review is to present an overview of the potential of tanniferous trees for the control of
gastrointestinal nematodes in sheep in the tropics. A systematic review of scientific articles in various databases
was carried out on the potential of tropical tanniferous trees, their effect on the control of gastrointestinal
parasites and the improvement of weight gain, a range of 16 years (2006-2022) was considered in the
publications consulting a total of 150, of which 46 were related to the topic for the selection of information, a
total of 31 scientific articles were obtained, which were considered. Table 1 shows that foliage extracts of species
considered tanniferous such as L. leucocephala cause inhibition of the hatching of eggs and on the infective larva
L3 of H. contortus. The bibliographic evidence consulted allows us to elucidate that the use of tropical trees with
forage potential and high contents of condensed tannins in their tissues can be successfully used for the control
of gastrointestinal nematodes in vitro and in vivo. The largest percentage of those consulted used tannin-bearing
plant extracts that have been shown to have anthelmintic properties and high nutrient content, making them
a viable and economical alternative for feeding small ruminants in production systems in tropical areas due to
their consumption preference and their high nutrient content.
