“…Microsatellite markers have been widely used in studies on indigenous and commercial duck population conservation in India, the Philippines, Vietnam, China, and other countries [3][4][5][6][7] because its characteristics of multiple alleles per locus, widely distributed in eukaryotic genomes, not strongly affected by selection, rich in polymorphic information, and low cost [8][9][10]. However, although a few studies have investigated the genetic polymorphisms of duck breeds for conservation, most studies investigated multiple populations at a single time point; no crossgenerational genetic monitoring study on ducks has been conducted.…”

Objective: Few studies have genetically monitored chickens over time, and no research has been conducted on ducks. To ensure the sustainable management of key duck breeds, we used microsatellite markers to monitor Brown Tsaiya ducks over time genetically. Methods:The second, fourth, sixth to eighth generations of the Brown Tsaiya duck selected feeding efficiency and control lines were included in this study to investigate the genetic variations, effective population size, population structure and the differentiation between populations over time with 11 microsatellite markers derived from Brown Tsaiya duck. Results:The results showed there were a slight decrease in the genetic variations and an increase in within-population inbreeding coefficient (FIS) in both line, but no consistent increase in FIS was observed in eacheither line. The effective population size in the second and eighth generations was 27.2 for the selected line and 23.9 for the control line. The change in allele richness (AR) showed a downward trend over time, and the selected line is slightly lower than the control line in each generation. The number of private alleles (Np) in the selected line were higher than in the control line. Moderate differentiation was observed between the second and eighth generations in the selected line (FST = 0.0510) and the control line (FST = 0.0606). Overall, differentiation tended to increase with each generation, but genetic variation and structure did not change considerably after six generations in the two lines. Conclusion:This study will as a reference for poultry conservation and help to implement cross-generation genetic monitoring and breeding plans in other duck breeds or lines to promote sustainable management.

“…Importantly, duck raising is often connected with fish farming, which could provide sustainable development for small farmers (Minh et al, 2006). Recently, we have also indicated a high level of genetic diversity in domestic duck populations in Vietnam (Pham et al, 2021).…”
