Contextualization: Livestock production in Colombia is developed in a large part of the national territory, with a 53% share of livestock gross domestic product. It is considered an important socioeconomic line for the field progress. It occupies a significant fraction of land use, destined predominantly to pasture and forage for cattle. This activity is carried out in large areas and increases in productivity depends on the efficient management of forages and the introduction of improved forage species able to offer better quantity and quality of food.

Research gap: A serious problem in forage management is the high production costs of fertilizers chemically synthesized and the fact that farmers do not take advantage of organic fertilization alternatives.

Purpose: Taking into account that few farmers consider grass as a crop, in agree with appropriate agronomic practices, this research aimed to evaluate the response of two interesting forage species for livestock (Cynodon nlemfuensis and Brachiaria brizantha cv. Toledo) to fertilization with aerobic fermented organic liquid fertilizer (ALOFA), with respect to different variables (height, coverage, vigor, biomass production and nutritional composition) in order to compare this commercial biofertilizer with traditional fertilization.

Methodology: A complete randomized block design (BCA) with three replications was used. Applications were made with intervals of 10 days according to the doses established by treatment. Three evaluations were carried out every 40 days and the response variables were height, coverage, vigor, infestation of pests, incidence of diseases, production of dry matter and nutritional quality.

Results and conclusions: A.L.O.F.A at 2.5% showed the best performance in dry matter (DM) production with C. nlemfuensis, exceeding the control by 17.55%; B. brizantha cv. Toledo ALOFA 2.5% + Mycorrhizal Inoculant (IM) and BP-150 0.5% + IM treatments exceeded the control by 35%, which allows increasing the animal load by 0.4 and 1.82 UGG / ha in both crop species. The highest percentage of DM was obtained with T4 treatment and taking into account that in terms of protein content there are no differences between treatments, it is concluded that these treatments do not affect the nutritional quality of the forages.
