Despite the use of modern anthelmintics to treat and control parasitism in animal production systems, these illnesses continue affecting both animals' health and diminish production parameters. One of the most important is gastrointestinal nematodiasis which is present in temperate and tropical conditions and represents larges economic losses. The concern increases with the new nematode isolates resistant to different broad-spectrum anthelmintic families (multi-resistant isolates). In addition to social pressure to have food that is safe and that does not harm the environment. The above, leading to the development of alternative gastrointestinal nematode control methods and allows to decrease the excessive use of commercial anthelmintics, extend the useful life of these products and help to have sustainable animal production systems. However, first, this valuable information is encountered in specialized periodic journals in the English language, second due to its high cost, it is difficult to access in general for students and producers who need to know about this information for its application in production systems. A literature review was carried out about the alternative control strategies of nematodes in ruminants that have been developed worldwide with a simple explanation of their potential use, the results obtained so far, and that their dissemination free of charge to make it available to the public. The above using the access granted by the Autonomous University of Campeche to databases such as Elsevier, Springer, and Ebsco Host.
In tropical regions with warm and temperate climates, gastrointestinal nematode infections (GIN) are the main problems affecting the health and welfare of sheep. One of the strategies to control these infections is the selection of individuals genetically resistant to GIN. Such resistance implies the optimal development of the immune response, where animal nutrition plays an essential role. The objective is to describe the immune response, the development of resistance against GIN in sheep, and the use of nutrigenomics as a tool to evaluate the effect of dietary nutrients on the expression of genes involved in the immune response using a literature review. The conclusion is that for the proper functioning of the immune system, it is essential that animals have energy, protein, and micronutrients for cellular synthesis and other functions that demand a lot of energy during an infectious event.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
