The following work was conducted in the community of Socononi, La Paz, in which we analyzed the effects of three different portions of saka or suncho (viguera pascensis) during the growth, and fattening stages in guinea pigs (cavia aparea porcellus). We used 32 mestizo guinea pigs (improved Peruvian creole breed) weaned 21 days after birth. Four treatments were administrated to the 32 animals (16 males and 16 females), the treatments were the following: (R0) or witness, consisting of corn alone, (R2) consisting of 30% of saka, (R3) consisting of 50% of saka, and (R4) consisting of 70% saka. The variables were evaluated under a completely randomized design study with four repetitions. The bromatological analysis of the saka in a dry sample registered the following data: 5.27% of humidity, 13.8% of ash, 29.05% of fiber, 1.5% of lipids, 42.17% of protein, 8.21% of carbohydrates, 1996.75 mg of Ca, and 883.7 mg of P. We collected the following data in a moisturized sample: 86.91% of humidity, 2.065% of ash, 3.065% of fiber, 0.21% of lipids, 6.29% of protein, 1.015% of carbohydrates, 264.6 mg of Ca, and 116.44 mg of P. The weight after weaning was analyzed at the beginning of the study. We could not find any significant difference from the 4 groups in the study, though, the gender factor presented significant differences (p<0.05), males had a greater weight gain than females at the moment of weaning with 219.75 gr in males , and 207.75 gr in females. The final weight and daily food consumption was greater for those who received the R2, R3, R4, in relationship with the witness group. Males presented a greater weight gain with 726.31 gr, while females presented a total weight of 600 gr. The highest amount of weight gain was 39.66 and 37.05 gr/week for those who received the treatments of 30 % and 50% of saka; it is possible that saka had a direct correlation with the weight gain. After performing the economic evaluation, we concluded that feeding guinea pigs with saka at a 50% results in a better economic benefits, obtaining 1.39 Bs per each male, and 1.22 for each female.
