Elaboración de bloques nutricionalesmediante el uso de origanum vulgare y thymus vulgaris (orégano y tomillo) como promotores de crecimiento natural para la alimentación de cuyes.

Abstract

Nutritional blocks were developed through the use of Origanum vulgare and Thymus vulgaris (oregano and thyme) as natural growth promoters for guinea pig feeding, the productive behavior of guinea pigs was evaluated when different levels of oregano and thyme were used in their diet, 10, 20, 30% in the elaboration of the nutritional blocks, during the stages of growth and fattening of guinea pigs, analyzing the production cost of each treatment; with an experimental methodology, in the sector of Chimbacalle of the canton Quito in the province of Pichincha, under a completely random design in combinatorial arrangement of two factors, for which six treatments and a control treatment for Factor A were used, which corresponds to the different levels of natural promoters with three repetitions each and for Factor B, the effect of the natural promoters under the sex of the animals was analyzed, each experimental unit conformed by 2 guinea pigs giving a total of 84 ones under study in a period of 75 days. Regarding to the factor A, significant differences were recorded (P<0.01) for the productive parameters, such as the consumption of green forage (Kg/FV) and weight to the carcass (Kg), being the best treatment the one with 20% of inclusion of oregano (T2) with values of 2.46 ± 0.03 kg/FV and 0.88 ± 0.03 kg respectively, for the factor B under study, significant differences were recorded (P<0.01), for the consumption of green fodder (kg/FV), being better the consumption of the males with 2.42 ± 0.01 kg/FV; in turn, the best cost benefit was the Treatment with 20% of inclusion of oregano (T2) with 1,23 USD and a profitability of 23%. It is concluded that regarding the productive variables of the guinea pig, the best treatment is the one including 20% of oregano, since the quality of the guinea pig is increased and it is obtained a better profitability of it. It is recommended to the cunicultural producers the implementation of natural growth promoters in their rations since it allows a better development of the guinea pig, assuring a better price of the carcass.
