The influence of supplementation of a lecithin emulsifier (0.1%) to the commercial feed mixture for piglets after weaning was studied. Twenty-eight control and 28 experimental piglets were monitored in a 28-day experimental period after weaning at 28 days of age. The weight of piglets and feed consumption were monitored in weekly intervals. Faeces were collected from the floor of pens on the last two days of each week to determine the digestibility of different nutrients. The average daily weight gain (C = 383.3, E = 399.5 g) of the experimental group was statistically insignificantly higher, whereas the feed conversion ratio (C = 1.959, E = 1.808 kg/kg) was found to be statistically significantly lower. The positive influence on the digestibility of crude fat and ash was more significant in the first half of the experiment, whereas the influence on the digestibility of crude protein, crude fibre and organic matter persisted during the experiment. The supplementation of lecithin emulsifier to the feed mixture for piglets has a positive impact on the utilisation of dietary nutrients.
