Sažetak

Over several past years, the weather in Croatia in the autumn was unfavourable, causing increased mycotoxin levels in corn used in duck feeding. On Croatian market, there are several products for elimination of the negative effect of mycotoxins. The aim of this trial was to investigate the efficiency of Mycosorb and Sel Plex in duck fattening, through body weight gain, feed conversion, mortality and covering variable costs of production. In the trial there were 1140 one day-old Cherry Valley ducklings randomly assigned to two groups (control K and experimental P) of 570 birds. The trial period of 47 days was divided into two phases: phase 1. from day 1 to 21 and phase 2 from day 22 to day 47. Both starter and finisher feed for group P were supplemented with 0.05% of Mycosorb and 0.03 % of Sel Plex. At the age of 47 days ducks from group K achieved the average body weight of 3060 g, while birds from group –P had finishing body weight of 3150 g. Feed conversion in group K was 2.51 kg/kg and in group P 2.45 kg/kg. Mortality in group K was 7.02% and in group P 5.97%. Variable costs for one hundred ducks in group K were 1,234,69 kn and in group P 1,423,70 kn. Better production results achieved in group P justify the use of Mycosorb and Sel Plex in duck feed.
