This study examines the behavioral patterns, eating habits, mating behaviors, and egg-laying productivity of Crested Philippine Mallard Ducks in comparison to ordinary Mallard Ducks. The research aims to determine the influence of the crested gene on these aspects, with a focus on genetic predispositions, mobility, and reproductive performance. A total of 11 Crested Mallard Ducks and 11 ordinary Mallard Ducks were observed over a 10-day period, documenting their daily activities, feeding patterns, and egg production. Results indicate that while both groups exhibit similar general behaviors, Crested Mallard Ducks show slight neurological impairments that may affect their foraging efficiency and overall productivity. Mating behaviors were comparable, but variations in dominance and pair bonding suggest that specific breeding management may be required for crested ducks. Egg production data reveal that Crested Mallard Ducks lay slightly fewer eggs than their ordinary counterparts, with fluctuations attributed to genetic and environmental factors. The study concludes that while the Crested Philippine Mallard Duck remains a viable breed for poultry farming, careful breeding strategies, optimized nutrition, and improved housing conditions are essential for maximizing its productivity. Further research is recommended to explore long-term genetic interventions that could enhance the viability of this breed in the Philippine duck industry.
