the effects of adding a high intensity sweetener (his) to feed and of the combination of adding a milky flavor (mf) in drinking water and in feed on the performance of weanling pigs were investigated. one hundred and twenty newly weaned 26 d-old pigs (landrace x pietrain) in 24 pens of 5 animals each were used. the animals were offered free access to 4 experimental diets consisting of a basal diet (t-1) and the same diet with three different flavour preparations: his (t-2), mf (t-3) and the same mf enhanced with an orosensorial supplement (t-4). the composition of the basal diet changed from a pre-starter to a starter specification on day 13 of trial. additionally, the animals from each experimental treatment had free access to different water supplies that in the case of treatments t-3 and t-4 contained the same mf up to d 22 of trial. for the first 4 d after weaning the animals on t-4 had a higher (p<0.05) adfi than those on t-2 (90 vs 41 g/d). for the whole pre-starter phase, the animals on t-3 and t-4 also had a better (p<0.05) g:f ratio than those on t-2 (0.484 and 0.532 vs 0.303 g/g, respectively). during the starter phase, the animals on t-2 and t-4 had a higher (p<0.05) adfi than those on t-3 (698 and 682 vs 586 g/d, respectively). overall the 28 day trial, the animals on t-4 had a higher (p<0.05) adfi than those on t-3 (463 vs. 394 g/d) while t-1 and t-2 were intermediate (435 and 449 g/d). final average body weights at the end of the trial were 17.43, 16.79, 16.65 and 16.06 kg for animals on t-4, t-2, t-1 and t-3 respectively. it is concluded that, treatment with a his may reduce adfi during the pre-starter phase. the addition of a milky flavour in the drinking water after weaning together with an enhanced milky flavour in the feed improved adfi and g:f in the pre-starter phase as well as adfi in the overall experiment resulting in apparently heavier piglets
