Effect of using vanilla sweet aroma in diets for weaning pigs

The trial was conducted on 108 piglets of crossbreeds Landrace x Large White. Aim of this study was to determine influence of this aroma on production parameters of growing pigs. Whole trial was in total 57 days, and it was split in three trial periods. Piglets were weaned on day 27, when the trial started. First trial period was 18 days (27-44 day), second was 28 days (45-72 day) and third was 11 days (73-83 day). The control groups received standard farm mixtures, and the trial groups had added aroma Vanilla Sweet in different concentrations (0.02; 0.04%, respectively). During the first period, there was statistical difference (p<0.05) in all three prameters between the groups. Feed intake (FI), average daily gain (ADG) and feed conversion (FCR) differed between C and T1 group. T1 had best ADG of 261.53 g/d and FCR of 1.89 g/g. In the second period statistical significance was noted in FI and ADG, between T1 and other two groups. T1 had lower FI and ADG, but better FCR compared to control group. In the final period second experimental group had the best results in both FI (1309.29 g/d) and ADG (696.43 g/d). And eventualy for whole trial T2 had better results in all three production parametars compared to other two trial groups. In general, obtained results showed that use of Vanilla sweet aroma can be recommended in the nutrition of weaned pigs. Further investigation should be conducted to determine the effect of this flavour on fatteners.
