Experiments were carried out to evaluate the use of autoclaving diets for growing rats. To evaluate the performance, rats born from females receiving or not autoclaving diets during the gestation were distributed in a randomized experimental design, with two treatments and a one-animal experimental unit. The diet used for female rats in gestation did not influence the weight of the rats either at birth or during the weaning period. As for digestibility and performance assays, rats from both kinds of females (with and without autoclaving diets during gestation) were distributed in a 2x2 factorial outline (normal or autoclaving diets until weaning versus normal or autoclaving diets after weaning). There was a reduction in the digestive use of the autoclaving diet gross energy after weaning and a worsening in the alimentary conversion in the period up to 42 days. The protein solubility in KOH test is a good indicative of the diet's nutritional quality loss
