Sažetak
An investigation upon the daily dynamics of the separate elements of mule ducks behavior has been carried out at the Institute of Fisheries and Acuaculture Plovdiv, Bulgaria, applying the schedule of feeding with partial restriction, at conditions of integrated fish-ducks technology. Our investigation has shown that the fishponds have been suitable for mule ducks rearing – the birds have had a good plumage status without demonstrations of cannibalism and
aggressiveness. Together with the fattening period advance, ducks have spent less time for feeding and have reacted rather weakly to forage supply; the dry land stay time has been on the account of the fish-pond stay, having in mind that the swimming time has increased, as well as the rest time in the fish-pond together with the advance in age.
