Abstract
En la crianza de cuyes, la alimentación representa el 80% de los costos de producción, que al irse encareciendo dificultan la adecuada provisión de nutrientes, con su subsecuente decaimiento del potencial productivo. Por ello, el estudio busca evaluar la influencia del suero de leche sobre nivel de consumo, ganancia de peso y conversión alimenticia en cuyes. Se trabajó con 36 cuyes machos de tres semanas de edad, 333 g de peso vivo en promedio, raza Perú, los que fueron distribuidos aleatoriamente en tres tratamientos, cuatro repeticiones de tres cuyes cada una, alimentados con alfalfa (Medicago sativa) + concentrado, ración base que se complementó para tratamiento 1, con agua potable; tratamiento 2, con suero de leche; y tratamiento 3, con agua potable + suero de leche. Durante ocho semanas se evaluó el consumo de alimento, realizando el análisis de varianza correspondiente a un diseño completamente al azar. El consumo de suero de leche solo o en adición al agua, mejora la ganancia de peso y la conversión alimenticia; el incremento de peso (750 y 729 g) en los tratamientos 2 y 3, estadísticamente similares entre sí, fueron superiores (P˂0.05) al incremento (622 g) en el Tratamiento 1; la conversión alimenticia de 3,4 y 3,8 en estos tratamientos resultaron superiores (P˂0.05) a 5,2 del tratamiento 1. Se concluyó que, sobre el nivel de consumo de alimento, el suero de leche no ejerce influencia; mediante su complemento solo o en adición al agua, se disminuye costos de producción y el periodo de engorde.
In guinea pig breeding, feed represents 80% of production costs, which, as it becomes more expensive, hinders the adequate supply of nutrients, with a subsequent decline in productive potential. Therefore, the study seeks to evaluate the influence of whey on the level of consumption, weight gain and feed conversion in guinea pigs. We worked with 36 male guinea pigs of three weeks of age, 333 g live weight on average, Peru breed, which were randomly distributed in three treatments, four replicates of three guinea pigs each, fed with alfalfa (Medicago sativa) + concentrate, base ration that was supplemented for treatment 1, with drinking water; treatment 2, with whey; and treatment 3, with drinking water + whey. Feed intake was evaluated for eight weeks, performing the analysis of variance corresponding to a completely randomized design. The consumption of whey alone or in addition to water improved weight gain and feed conversion; weight gain (750 and 729 g) in treatments 2 and 3, statistically similar to each other, were higher (P˂0. 05) to the increase (622 g) in Treatment 1; feed conversion of 3.2 and 3.8 in these treatments were higher (P˂0.05) than 5.2 in Treatment 1. It was concluded that whey has no influence on the level of feed consumption; by supplementing it alone or in addition to water, production costs and fattening period are reduced.
