Abstract
The objective of this research was to evaluate the effect of nutritional blocks formulated with different energy sources, inguinea pig feeding (Cavia porcellus) in growth and fattening stages; Evaluating: Food consumption, weight gain, feedconversion, carcass yield, mortality and profitability. Using random block design with four treatments, 10 repetitions; 21experimental units per treatment: T1 control = Fodder (Rye grass + Alfalfa), T2 = Fodder + Nutritional block with cornmeal,T3 = Fodder + Nutritional block with wheat bran, and T4 = Fodder + Nutritional block with rice powder. In thevariable food consumption based on dry matter, the highest consumption in T1 was determined with an average of5312.62 g per week. T2 presented the greatest increase in weight with an average of 702.11 g. T2 reached the best foodconversion, whose ratio is 3.65 to 1. T2 achieved the best yield of carcass, with 73.75%. The highest mortality occurs inT1 and T4 with 19.05%. The treatment two presented the best profitability, with 30.72%.
