Six hundred day-old Pekin and Muscovy male ducklings were raised on diets based exclusively on food wastes to market ages of 7 and 11 weeks, respectively. Three dietary treatments were offered to the birds: commercial pellets (control), feeds consisting partially of food waste, and feeds consisting entirely of food waste. The two experimental treatments each had a dry pelleted diet and a wet mash diet. Twenty-four carcasses from each breed were analyzed to determine the effects of the experimental diets compared to those of the control (commercial pellets). In addition to corn and soybean meal, a total of nine food waste ingredients were tested. The precise-feeding technique was performed to establish DM, fat, and fibre digestibility as well as N retention, AME, AMEn, TME, TMEn values for the 11 feedstuff ingredients. The results of this study provide reliable data for formulation of duck diets using the tested food waste ingredients as well as corn and soybean meal in both Pekin and Muscovy ducklings at 2 different ages during growth.
