Abstract

The research was carried out in the alpaca production unit of the Tomas Peasant Community, of the Lima Region, with the aim of identifying the floristic component of the pasture of a wetland area in the dry season of the year and the species that were most consumed by alpacas. Previously, the floristic inventory of 5 hectares of pasture was carried out and 10 mother alpacas and 10 tuis alpacas were assigned. During the study period, stool samples were taken to evaluate the diet by the microhistological method. The chemical components of the six main species of grasses most consumed were analyzed. In the initial inventory 36 species were found, of which the most consumed were 10 that made up approximately 80% of the diet. Chemical analysis shows a crude fiber content in a range between 66,23 to 77,24%, crude protein between 2.49 to 5,21% and vitamin A between 0,08 to 0,37 mg / 100g. The contribution of the present is to identify the species of pasture most consumed by alpacas tuis and mothers, in order to take care in their conservation.

Summary

35 Tetraglodin cristatum

100,00 un 3,94 % de la dieta diaria, se podría asumir que es debido a que llega a la etapa de dormancia con mayor intensidad al punto que su tallo se pone más duro y las hojas se involutan, lo que la hace menos apetecible por las alpacas. En la Tabla 3 se muestran las 10 especies de plantas de mayor consumo por alpacas tuis, que equivale al 79,49 % de su ración diaria; para estudiar si el consumo es debido a la mayor abundancia o son escogidas por su gustosidad, se sometió a una evaluación mediante correlación de Pearson, comparando la cantidad de veces que se encuentran estas 10 especies en el pastizal y la cantidad de veces que se encuentra en la evaluación microhistológica de las heces. El resultado nos demuestra que no existe correlación llegando a un mínimo de 0,117 positivo, por tanto, concluimos que el consumo de los pastos por alpacas tuis es más por la gustosidad que por la cantidad de especies que existen en el pastizal
