Differential protein profiles in duck meat during the early postmortem storage period.

The present study was designed to investigate proteomic differences in duck breast muscle during the early postmortem storage period. The meat quality was evaluated at 0 hr and 24 hr postmortem at 4°C in Pekin ducks, black Muscovy ducks and Mule ducks. Differentially expressed proteins were detected by two-dimensional gel electrophoresis (2-DE) and matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF/TOF MS) at 0 hr and 24 hr postmortem in the three duck breeds.

Ovarian transcriptomic analysis of Shan Ma ducks at peak and late stages of egg production.

Objective: To assess the differences in ovarian transcriptomes in Shan Ma ducks between their peak and late stages of egg production, and to obtain new transcriptomic data of these egg-producing ducks.

Methods: The Illumina HiSeq 2000 system was used for high throughput sequencing of ovarian transcriptomes from Shan Ma ducks at their peak or late stages of egg production.

Results: Greater than 93% of the sequencing data had a base quality score (Q score) that was not less than 20 (Q20).
