    The present research evaluated the impact of dietary vitamin C supplementation on productive parameters and body fat accumulation in guinea pigs (Cavia porcellus) during the fattening stage. The study was conducted in Cuenca, Ecuador, using 80 crossbred guinea pigs from the Peru line, distributed in a completely randomized design with four treatments: a control group (T0) without additional vitamin C supplementation, and three increasing levels of pure ascorbic acid: 200 mg/kg (T1), 240 mg/kg (T2), and 280 mg/kg (T3) added to the concentrated diet. The feeding system was mixed, consisting of green forage (ryegrass and alfalfa) and commercial concentrate. The results indicated that supplementation did not produce statistically significant changes in volumetric growth parameters, such as feed intake, total weight gain, final weight, and carcass yield; however, average daily weight gain showed a significant increase with the 280 mg/kg dose regarding the animals' daily growth rate. Similarly, fat deposition increased significantly in visceral and subcutaneous fat, with treatments T1 and T2 showing the highest total fat deposits compared to the control group. These results suggest that ascorbic acid dosages act as a regulator of carcass fat deposits and energy reserves rather than as a primary promoter of total body mass growth.
