Tipos de vegetación del bosque protector Aña Moyocancha para la alimentación de alpacas (Vicugna pacos).

Abstract

The present research work aimed to know the types of vegetation of the Aña Moyocancha high altitude protective forest for the feeding of alpacas (Vicugna pacos). The experimental units were related to the four altitudinal floors (3800, 3900, 4000 and 4100 m.s.n.m) with three transept of 100 meters. For the bromatological analysis, the Fully Azar Design was used with three repetitions, the variables were subjected to the Adeva variance analysis and the means to the Tukey P ≤ 0.05 test. On the other hand, for the botanical composition, condition of natural grasslands, plant cover and physical chemical analysis of the soil, descriptive statistics were applied. In the four altitudinal floors the vegetation presented a great floristic diversity grouped into 8 families and 27 species, corresponding to the following percentage of family: Rosaceae (20.15%), Apiaceae (7.87%), Poaceae (45.23%), Cyperaceae (3.47%), Asteraceae (20.68%), Fabaceae (0.93%), Haloragaceae (0.67%), Plantaginaceae (1%), the grasslands exhibited a level of vegetation cover of 93.69% with an excellent condition and soil rich in nitrogen, phosphorus and potassium. It is concluded that the natural grasslands that are at 3800 m.s.n.m are those with the highest protein content (14.98%), while the grasslands that are at 4100 m.s.n.m are fibrous grasslands (31%), so it is recommended that the feeding of the alpacas should be on the lowest floor since it has better nutritional characteristics.
