Efecto de la utilización de ácido ascórbico en el concentrado para la alimentación de cuyes mestizos

Abstract

In the city of Ambato, at Izamba parish, the use of a commercial concentrate plus ascorbic acid (50, 100, 150 mg/ kg of food), in comparison to non ascorbic acid addition, was evaluated. 60 males crossbreed guinea pigs of 21 days of age, with an average weight of 324,02 g, were distributed with a Completely Randomized Desing (CRD), with 3 repetitions per treatment. ANOVA were used and Tukey test was performed in order to separate the means. In the results of productive behavior of the variables: final weight, weight gain, concentrate intake, feed conversion, not significant differences were established. However, numerically, a better response was obtained with 150 mg of ascorbic acid / kg of food with (1004,00 g, 677,33 g, 2299,98 g, 4,76, respectively). With regard to the variable carcass yield, highly significant differences were established, the best value (67,32 %) was found with 50 mg of ascorbic acid. When the economic analysis was carried out, it was determined that 50 mg of ascorbic acid animals had the biggest benefit cost, with 1,26USD, which means that for each dollar invested, it is recovered 0,26 USD. Therefore, the use of ascorbic acid didn´t affect the biological behavior of males crossbreed guinea pigs. In conclusion, it is recommended the use of 50 mg of ascorbic acid / kg of food, for the guinea pigs feeding during the growth-fattening stage.
