Evaluation of the Utilization of Waste bread meal as an Alternative Energy Feed on the Performance and Meat Quality of Male Peking Ducks

Abstract

This study aimed to evaluate the utilization of waste bread meal  flour as an alternative energy feed ingredient on the performance and meat quality of male Peking ducks (Anas platyrhynchos domesticus). The experiment was conducted at the Poultry Production Laboratory, Feed Production Unit, and Nutrition and Feed Science Laboratory, Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru, from March to June 2025. A total of 80 male Peking ducks were reared for 8 weeks using a Completely Randomized Design with four treatments and five replications: P0 (0%), P1 (10%), P2 (20%), and P3 (30%) waste bread meal  flour in isoprotein diets by partially replacing corn and rice bran as energy sources. Observed parameters included feed intake, body weight gain, feed conversion ratio, final body weight, abdominal fat percentage, and meat cholesterol content. Data were analyzed using ANOVA followed by Duncan’s test. The results showed that waste bread meal  flour significantly (p<0.05) affected body weight gain, feed conversion ratio, final body weight, and meat cholesterol content, but had no significant effect (p>0.05) on abdominal fat percentage. The best performance was obtained at the 30% inclusion level with body weight gain of 856.10 g/bird, feed conversion ratio of 4.11, and final body weight of 1323.42 g/bird, while the lowest cholesterol content was observed at the 20% level (70.57 mg/100 g). In conclusion, waste bread meal  flour up to 30% can improve growth performance and reduce meat cholesterol content of male Peking ducks, indicating its potential as an alternative energy feed ingredient.
