In Ecuador the production of ruminants is limited,availability of resources for education, learning problems in dry and tropical regions, the availability of grasses to covernutritional needs, not for animal information, in order to reduce the extensive grazing areas for feeding. The silvopastoralsystems, the use of post-harvest residues of crops of plant origin, are presented as a cost-effective alternative for sustain- able livestock production, due to the large quantity and quality of the biomass for use, throughout the year, even in timesdry. The foliar mass of trees, shrubs and residues are characterized by being rich in nutrients, however, as regards thepresence of metabolites, especially tannins, which decrease voluntary consumption, the digestibility of nutrients and theProduction of the animals, effects that are associated to the concentration in the diet and the quantity consumed, as wellas the state of health of the animal. Studies indicate that in moderate proportions (20-45 g kg-1 of dry matter) improve- ments in animal performance have been shown by reducing ruminal methanogenesis and degradation of forage protein inthe rumen. The (GHG), CO2 is the one that is in the highest amounts that currently is responsible for the increase inglobal warming compared to other greenhouse gases. The objective of the research is the contribution to knowledge, theuse of agricultural by-products, as well as the implementation of alternative systems in feeding and production of ruminants.","PeriodicalId":31533,"journal":{"name":"Journal of the Selva Andina Animal Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72473358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

La atencion en plantas con estas propiedades se debe principalmente a la aparicion y extension de poblaciones parasitarias resistentes a los antihelminticos. Recientemente en Yucatan se ha reportado el efecto de AH de extractos vegetales sobre huevos de Haemonchus contortus mediante la prueba de inhibicion de la eclosion. Entre las principales especies vegetales con propiedades AH destacan los extractos etanolicos y hexanicos, principalmente del follaje de Lysiloma latisiliquum, Laguncularia racemosa, Rizophora mangle y Avicennia germinans, Theobroma cacao y Coffea arabica. Sin embargo, recientemente se ha observado que las leguminosas son una importante fuente de metabolitos secundarios como Leucaena leucocephala, Lysiloma latisiliquum, Acacia cornigera y Mimosa bahamensis. La evidencia demuestra que los metabolitos secundarios que contienen algunas leguminosas forrajeras afectan diversos procesos biologicos de los nematodos gastrointestinales de rumiantes, por lo que podria ser una alternativa para el control de helmintos en la produccion de pequenos rumiantes.","PeriodicalId":31533,"journal":{"name":"Journal of the Selva Andina Animal Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88569822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
