摘　　要：Background:Evaluation of forage resources is vital for the sustainability of livestock farming in the South American Andes,especially under conditions of low water availability for irrigation and acid soils.Methods:We evaluated the productivity and nutritive value of two cultivars of chicory(Cichorium intybus L.)and one of plantain(Plantago lanceolata L.)in three high-altitude sites(AL)of the northern highlands of Peru:AL-Ⅰ:2300–2800 m.a.s.l,AL-Ⅱ:2801–3300 m.a.s.l.and AL-Ⅲ:3301–3800 m.a.s.l.,for 1 year.The parameters evaluated were dry matter yield(DMY),plant height(PH),growth rate(GR)and nutritional value.Results:Plantain achieved the greatest annual DMY(ADMY),PH and GR compared to the two chicory cultivars(9.34,9.56 and 13.39 Mg ha−1 for Puna Ⅱ and Sese 100 chicory and Tonic plantain,respectively;p=0.0019).The greatest ADMY and GR occurred at AL-Ⅰ.Regarding nutritional value,differences were observed only for in vitro digestibility of dry matter and metabolisable energy with chicory cultivars higher than plantain.Conclusions:The results indicate that the three cultivars evaluated may be used as a nutritional supplement in cattle feed,associated with grasses because they have high nutritive value suitable for milk production in the mountain regions of Peru.
