The guinea pig (Cavia aperea porcellus) is an alternative to improve human nutrition because its meat is of excellent taste and quality. Thus, it is an important nutritional source. The feed conversion index was determined under the basic (forage) and mixed (forage and concentrate) diets during the growth phase. This was done with both sexes located in the Tamborada and MEJOCUY populations, using the AUQUI, and San Luis lines. This was done in order to quantify how many kilograms of feed an animal must eat to gain one kilogram of live weight. The animals were randomly distributed into individual pools based on population, line, and sex for the period from 14 to 56 days old. Depending on the feeding system used, they received alfalfa forage and/or concentrated feed. In addition, they were weighed before and after feeding so the difference between food eaten and food rejected could be calculated. At the end of the 42 days of investigation, the feed conversion indexes were 5, 5.1, 4.8, and 4.6 for the basic diet and 5, 5.5, 4.9, and 4.9 for the mixed diet for the guinea pigs of the Tamborada and MEJOCUY populations and the AUQUI and San Luis lines respectively. The male and female animals had indexes of 4.7 and 5.3 respectively. Generally speaking, the San Luis line has the best feed conversion index, followed by the AUQUI line, the Tamborada population, and lastly the MEJOCUY population.
