A study with the aim of evaluating the reversibility of the nutritionally induced changes in the scrotal and testicular characteristics of young rams was conducted. Thirty-six Dorper rams, 11 to 12 months of age were randomly divided into three groups of 12 rams each and fed at different energy levels for 127 days. At the end of this period, half of the animals from each group (n = 6) were slaughtered. In the second phase of the trial, the energy level of the diet was standardised and all animals were fed on the same low energy diet for 90 days, before being slaughtered. The carcass, scrotal and testicular characteristics of the slaughtered animals were assessed at the end of each phase and the results compared within groups to evaluate the reversibility of the nutritionally induced changes. Results indicate that scrotal fat deposited during periods of high-energy intake was mobilised during periods of restricted energy availability.
