Utilización de zeramec y boldemec como promotor de crecimiento de cuyes mejorados durante la etapa de crecimiento - engorde

Abstract

In the Minor Species Production Unit ESPOCH, the use of two growth promoters (Zeramec and Boldomec) compared to a control treatment (Ivermectin) for the growth - fattening stage was evaluated; we had 96 guinea pigs weaned (48 males and 48 females) aged 30 days and an average weight of 0,314 kg., under a DCA in combinatorial array of two factors, where the factor A was made up of growth promoters and factor B sex-so we had 3 treatments with 8 repetitions and size of experimental unit of two animals. It was determined that the application of Zeramec improved growth performance of guinea pigs, highly significant differences were recorded as well for: final weight (1251.81 g), weight gain (941.97 g), feed conversion (6.37) weight and carcass yield (996 g, 76.53%). By effect of sex, males showed superiority over females, final weight (1239.63 g), weight gain (917.98 g), carcass weight 961 g, carcass yield 74.8%: at once they proved to be more efficient in feed conversion: 6.59. Economic analysis determined that when used Zeramec, the greatest benefit / cost ratio (1.29) was reached, so we suggest using Zeramec since better efficiency in production parameters and also economic profitability had got (29%).
