Measured egg weight, Haugh unit, albumen height and yolk color with digital egg scales and egg quality analyzers, and used candling equipment to screen for cracked shells and abnormal air cells, providing baseline data for egg quality assessment.
Extracted genomic DNA from frozen poultry serum samples, becoming proficient in lysis, centrifugation and purification, to obtain high-purity DNA supporting downstream genotyping and population genetic diversity analysis.
Took part in performance testing of the domestic white-feathered broiler (Wode 188): body measurements, slaughter and cutting, viscera processing and weighing, collecting phenotypes at both the farm and slaughterhouse ends.
