Monitoring changes in the genetic structure of Brown Tsaiya duck selected for feeding efficiency by microsatellite markers.

ABSTRACT:

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 for 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
