Sažetak
Duck breeding and production of duck meat and eggs are on the third place the poultry production and between 1993 and 2002, the output of duck meat grew by nearly 90%, from 1.71 to 3.21 million tons. Duck production in Croatia is mostly carried out through cooperation on family farms in several cycles per year. As there is a possibility of using home produced feed in duck feeding family farms, the aim of this investigation was to compare the effect of different composition, form and origin of feeds in ducks fattening. 5 500 day-old Cherry Valley ducks were divided in three groups: A, B and C. Feeds were from different producers, but corn was from the family farm. In group A were 4 000 ducks and they were fed pelleted feed from producer A, 750 ducks from group B were fed non-pelleted feed from producer B and 750 ducks from group C were fed diet prepared on the family farm from corn and concentrate. Ducks from group A had the average body weight of 3298.6 g at 49 days, group B 3118.5 g and group C 3247.0 g. The average feed conversion ratio during a 49-day period was: group A 2.55; group B 2.28 and group C 2.34 kg/kg. The average costs of feed per kg of live weight of ducks were: group A 9.85 kn; group B 9.52 kn and group C 8.23 kn.
