Abstract

Introduction. The use of associations of grasses and legumes allows to have greater nutritional value and dry matter yield. Objective. To evaluate six mixtures of perennial, annual and legume forages in the dry and rainy season in Nariño, Colombia. Materials and methods. The study was conducted between December 2017 and November 2018 at the Obonuco Research Center of the Colombian Agricultural Research Corporation (AGROSAVIA). A randomized complete block design was used, with an arrangement of sub-divided plots. The following were determined: PC (crude protein), FDN (neutral detergent fiber), FDA (acid detergent fiber), D (digestibility), ENL (net energy of lactation) and TC (growth rate of the species). The software R V.3.6.0 was used for the analysis. Results. The nutritional value of the mixtures for the season of high and low rainfall presented significant differences (p<0.05) at the age of 28, 35 and 42 days, where the mixture made up of Dactylis glomerata yielded the best results except for the PC at the age of 28 days. The best values for this mixture occurred in dry season. Conclusion. Mix 4 (Trifolium repens + Trifolium pratense + Dactylis glomerata) presented the highest growth rate and accumulation of CP at the age of 35 and 42 days in the two evaluated seasons. Therefore, it could be evaluated commercially as a food alternative for livestock systems in the high tropics of Nariño.
