    The feeding of Cavia porcellus is significant in the development of these animals, it is subject to the quality and contribution of nutrients, for this reason the objective was to evaluate the barley and alfalfa hay on the productive indices in the growth and fattening stages of guinea pigs, it was developed under a DBCA, with 4 treatments T1 3 % barley and alfalfa hay, T2 5 % barley and alfalfa hay, T3 7 % barley and alfalfa hay and T0 control with only green forage; in 3 repetitions, that is, 12 experimental analysis units with 5 animals each, total of 60 animals, it was compared using the Tukey test at 5% in Infostat, with the response variables initial weight in (g), final weight in (g), weight gain in (g), feed consumption, feed conversion, carcass weight in (g), carcass yield in %, mortality rate, cost / benefit ratio. The results for the chemical analysis the percentage of NDF the alfalfa hay in T2R2 with 56.79% and the T2R1 with 55.71%; for the FAD the alfalfa hay in T2R2 with 41.08% and T2R1 with 39.71%; the initial weight of the guinea pigs were T1 = 288.58 g; the T2 = 280.15 g; the T3 = 315.22 g and the T0 = 265.01 g; giving an average of 300 g; final weight in (g) for the T1 treatment with 676.38 g; the weight increase in (g) the T1 treatment with 387.80 g; the feed consumption the T1 treatment with 1848.57 g; the feed conversion the T1 treatment with 4.84 g; Regarding carcass weight, the highest value was found in treatment T1 with 422,75 g; carcass yield was highest in treatment T0 with 80.99%. It was concluded that the best treatment for the response variables was T1, which indicated the highest productive indices; in the cost-benefit ratio, it was found that T1 and T2 reported the highest benefits with 1.27 and 1.20 respectively.

    The study evaluated the effects of different proportions of hydroponic barley green fodder (FVHC) and feed concentrate in the feeding of guinea pigs in the growth and fattening stages. The treatments were distributed in five groups: 100% FVHC + 0% feed concentrate (T0), 75% FVHC + 25% feed concentrate (T1), 50% FVHC + 50% feed concentrate (T2), 25% FVHC + 75% feed concentrate (T3) and 0% FVHC + 100% feed concentrate (T4). The results showed that T2 (50% FVHC + 50% feed concentrate) was the most balanced and effective as it obtained significant weight gain and adequate feed conversion in the growth and fattening stage. On the contrary, T0 (100% FVHC + 0% feed concentrate) and T4 (0% FVHC + 100% feed concentrate) had limitations in which the former obtained higher feed intake and higher feed conversion, demonstrating that it was not sufficient to satisfy the guinea pig's nutritional requirements. On the other hand, T4 presented lower feed efficiency throughout the study because the insufficient amount of fiber negatively affected its performance. Finally, the study emphasizes the importance of a mixed diet to ensure optimal performance and welfare of the guinea pigs.
