Utilización de diferentes niveles de regano como promotor natural de crecimiento en la alimentación de cuyes en la etapa de crecimiento, engorde

Abstract

In the farm for Minor Species Program "GUASLAN" (MAGAP), located at San Luis Parish, Riobamba Country, Chimborazo Province, evaluated the effect of 3 levels of regano (0.5, 1.0, and 1.5%) in the feeding of guinea pigs for fattening in the growth stage, to be compared with a control treatment. It applied a completely randomized design (CRD) in a combinatorial arrangement of two factors, It worked with 80 guinea pigs of 15 days old, with an average weight of 0,400 kg. The use of different levels of regano as growth developer of guinea pigs in the stage of growth and fattening influenced in their biological behavior, in which recorded significant differences (P <0.01) and obtained the best results in final weight (1,32 kg), weight gain (0,94 kg), feed conversion (6,24 points), the carcass weight (0,92 kg), and carcass yield (71.71%) with the theatment T3 (1,5% of regano). When evaluating the biological behavior of animals according to sex, it recorded statistical difference (P <0.01) for the variable final weight (1,29 kg), weight gain (0,90 kg), carcass weight was recorded (0,90 kg) and carcass yield (68.41%) in guinea pigs males. The best benefit /cost was recorded with treatment T3, by using (1,5% of regano) with 1.18, What means that for each dollar invested, there is a profit of 0.18 USD. Therfore the use of regano in guinea pigs in the feeding process of guinea pigs did not affect the biological behavior in the animals. That is why; it recommend using the 1.5% of regano in the daily diet of guinea pigs during the growth and fattening stage, due to obtained significant statistical results in the evaluated parameters.
