Evaluación de diferentes pastos de la Amazonía (Axonopus Scoparius, Pennisetum, Echinochioa polystachia, Axonopus micay) más concentrado en la alimentación de cuyes en la etapa de crecimiento-engorde y gestión-lactancia

Abstract

In Santa Clara County, Pastaza province, the Amazon fodder were evaluated: gramalote , King grass , German pasture and micay pasture, together with supplements applied in growing - fattening in 80 male and female 30 days old weaned guinea pigs, and gestation-lactation 40 female at first birth, distributed under a CRD (Completely Randomized Design). The results were subjected to analysis of variance and mean separation (Tukey P 0.05). Finding that in growing - fattening the gramalote produced the best productive responses with a final weight of 0.84 kg, weight increments 0.43 kg, feed conversion of 9.08, carcass weight of 0.60 kg and the lowest cost/kg weight gain (2.44 dollars). According to sex, males had a better productive performance. In the gestation-lactation stage the results were statistically similar, weights at the end of the breeding of 1.18 kg, at postpartum 1.02 kg and at weaning 1.20 kg were registered, brood sizes at birth and at weaning were not numerous (1.69 and 1.39 pups/brood, respectively), although the weights of offspring weaning (between 216 and 256 g), are comparable to the offspring obtained in temperate climates. In growth - fattening the most benefit (B/C of 1.21) was achieved with gramalote, and gestationlactation with King grass (B/C of 1.15), so it is recommended for humid tropical ecosystems (Ecuadorian Amazon ), to feed the guinea pigs in grow-finish stage with gramalote and supplements, but in gestation-lactation, any of the evaluated grasses can be used.
