Abstract

A total of 43 Philippine White Mallard and Pekin ducks were compared and evaluated based on their growth performance and carcass yield. The experiment was laid out using the Completely Randomized Design with duck breeds as the treatments. The brooding and growing periods lasted for 30 and 60 d, respectively. Results of the study indicated that Pekin ducks showed a significantly higher growth rate (0.45 vs. 0.19) and feed consumption (11.49 vs. 7.65 kg) than Philippine White Mallard ducks at 12 weeks of age. Therefore, Pekin ducks were more efficient in converting consumed feeds into body weight. Body length (58.70 vs. 50.45 cm), chest circumference (41.43 vs. 31.30 cm), breast percentage (33.92% vs. 32.01%), breast fat (21.94% vs. 17.60%) and bone (13.22% vs. 12.24%) and leg fat (30.03% vs. 27%) were found to be significantly higher in Pekin ducks than in Philippine White Mallards. However, parameters such as hot carcass dressing percentage (82.29% vs. 77.69%), leg with thigh percentage (17.61% vs. 16.27%), breast lean (70.16% vs. 64.84%), leg bone (21.11% vs. 18.92%) and lean to fat ratio in both breast (4.02 vs. 2.98) and leg with thigh (1.93 vs. 1.71) were significantly higher in Philippine White Mallard ducks. Differences on portions of chilled carcass, wing, rib back and leg lean were found to be not significant (P>0.05). Pekin ducks were better than Philippine White Mallards with regard to physical attributes of dressed carcasses. Generally, Philippine White Mallard ducks are not highly recommended to be used in duck meat production due to its poor growth performance and feed conversion ratio.
