摘要: Gastrointestinal nematodes (GIN) could have a negative impact on the nutritional efficiency and productivity of sheep goats. However, feeding hosts can also affect parasites. This paper reviews literature data manipulation small ruminants as tool for control GIN under hot humid subhumid tropical conditions. Parasites are integrated into food chain foraging ruminants. A balanced grazing system provides an adequate source nutrients acceptable burden that allows optimum level productivity. breakdown in such balance may induce severe parasite infections. Diet strategies been tested Animals receiving supplementary achieve improved resilience against improvement resistance goats through supplementation has less studied many confounding factors should be considered (pattern fodder consumption, dilution eggs faeces, direct anthelmintic (AH) effect some ingredients, etc.). Some supplements cause AH (i.e. copper wire particles Haemonchus contortus). Meanwhile, bioactive plant secondary metabolites (PSM), tannins, more complex. PSM effects host reducing feed digestibility), yet animals consume plants at levels evident to The affected different stages their life cycle adults with fewer utero or reduced worm burdens). they new infections (affecting egg hatchability larvae motility faeces avoiding exsheathment incoming infective host). Grazing management explored most regions. Available results suggest alternate rotational both provide opportunities reduce dependence easily complemented feeding.
