The effects of a supplemental feeding strategy during mid-gestation on lean gilts body reserves, productive and reproductive performance were assessed. A total of 90 gilts were allocated into two treatments (Control, C, and Supplemented, S). Control sows (n = 43) were fed according to the level routinely used on farm (2.5-3.0 kg d, 2.9 Mcal metabolizable energy kg feed and 0.6% of lysine) throu...

However, measures of reproductive traits are not usually collected; consequently, correlated traits that could be used as indicators would be useful. We examined associations between measures of reproductive and productive efficiency that could be used as selection indicators. Data from 194 dams of the genetic groups Angus x Nelore, Carac...
