摘要

The integration of quantitative data on growth and reproductive traits in Asian ducks is critical for optimizing production systems, yet existing literature remains fragmented. This meta-analysis synthesized data from 45 eligible studies (selected from 312 articles up to October 2023) encompassing over 10,000 ducks. Based on random-effects models, the pooled body weight at 8 weeks was estimated at 1.20 kg (95% CI: 1.10–1.30 kg), with an average daily gain of 25 g/day. Reproductive parameters showed an average age at first lay of 150 days, a fertility rate of 78%, a hatchability rate of 72%, and production of 120 eggs per cycle. High heterogeneity (I² > 75%) was observed across traits, with breed origin and management practices significantly influencing them. Indigenous breeds exhibited greater reproductive resilience than commercial hybrids, while extended lighting duration significantly accelerated the onset of lay. These findings provide evidence-based benchmarks and highlight the urgent need for standardized reporting to inform future breeding strategies.
