Fenología de los pastos cultivados para la alimentación de alpacas (Vicugna pacos) en Aña Moyocancha.

Abstract

The investigation aimend to determine the phenology of cultivated pastures (Oats Sativa) for feeding alpacas. The study was carried out at Aña Moyocancha Height Station belonging to the Escuela Superior Politécnica de Chimborazo, Ciencias Pecuarias Faculty, located 85 km from Riobamba. The experimental units were related to soil characterization 25 samples were used, nutritional value 3 samples for bromatological analysis, germination percentage։ 100 seeds were used and for the phenological evaluation of forage oats and three floors were considered altitudes (3829, 3831 and 3833 m.s.n.m.) and each of these with 9 repetitions, so in this phase 27 experimental units were used. A completely random design was carried out for the evaluation of phenological variables; whereas, for the other variables, descriptive statistics were used, giving emphasis to measures of central tendency (mean) and measures of dispersion (standard deviation). The results show that, in all the phenological variables such as plant height, basal cover, number of stems per plant, number of leaves per stem, density and production of green fodder at 30 and 60 days of evaluation, there were no significant differences (p > 0.05). This indicates that there was no effect on the phoenology of the studied altitudinal floors. The bromatological analysis indicates that the nutritional value is about 14.36 + 0.29% crude protein and 19.80 + 0.66% crude fiber which meets the dietary needs of alpaca. It is concluded that forage oats were adapted to these three altitudinal floors with an average production of 13.25 tn/ha, therefore, so it is recommended to use this forage species for the feeding of South American camelids.
