Popis:	The implementation of efficient grazing technologies in high mountain cattle ranches in the department of Nariño (Colombia) increases the sustainability of these production systems and promotes the conservation of the landscape design. With the objective of evaluating the dry matter intake of F1 (Kiwi-cross x Holstein) and Holstein cattle biotypes, present in hillside areas of the Nariño mountain, a preliminary trial of individual consumption of ryegrass (Lolium perenne) was carried out in Pasto (Nariño-Colombia) with the gauging technique, and the results were compared with models reported in the literature. The data were analyzed as a completely randomized design, with repeated measures over time. Intake per gauging was higher (p0.05). On the other hand, the milk composition of F1 cows was superior (p
