COSTA, Lúcio Laudares et al. Flavours in the diets for piglets from 6 to 18 kg. R. Bras. Zootec. [online]. 2003, vol.32, n.6, suppl.1, pp. 1633-1638. ISSN 1806-9290. http://dx.doi.org/10.1590/S1516-35982003000700012.
A total of 192 weaning crossbred Landrace x Large White piglets weighing 6.9 kg and 23 days old was used to determine the effect of addition of flavours in simple or complex diet on the performance, blood parameters and the organs weight of piglets. A randomized block design, in a 2 x 3 factorial scheme, with two diets (simple or complex) and addition or not of two flavours (F1 and F2), was used. It was observed that the flavour addition did not affect weight gain, feed intake and feed conversion. The complex diet showed better feed conversion than the simple diet. The blood glucose concentration was higher in the pos-prandial period. The simple diet showed higher effect on the glucose levels. The blood glucose concentration was not influenced by the tested flavours. The insulin showed higher levels in the pos-prandial period, although it was also not influenced by both diets, as well as the tested flavours. The weight of liver, pancreas and kidneys was not affected by the addition of flavours, therefore, simple diet showed higher weight, when compared to the complex diet. It was concluded that the used flavours showed no effects on the piglet performance, blood parameters and organs weight.
