The objective of this study was to evaluate the effects of creep feeding during the pre-weaning stage on the performance of piglets at nursery phase, as well as to estimate the economic viability of its application. A total of 125 piglets were exposed to creep feeding and evaluated qualitatively regarding diet intake and quantitatively regarding weight gain. After determining the eaters and non-eaters' piglets, 48 of these animals were evaluated in the nursery phase. Piglets are blocked (initial weigh and sex) and divided into eaters (E, n=24) and non-eaters (NE, n=24). Time to start feed intake, growth performance data and economic viability were analyzed. At pre-weaning phase no weight difference was observed, and only 24.5% of piglets consumed the creep feed after 12 days of exposure. At nursery phase, the E group presented a 250% faster consumption in the first 24 hours of housing, 18.3% greater daily feed intake and 22.0% greater daily gain for whole experimental length, when compared to NE group. The economic evaluation demonstrated a 269% and 225% greater economic profit and return on investment for E. Therefore, the application of creep feeding in pre-weaning improves the piglets' performance during nursery phase and is economically viable. (AU) | |
