Abstract:
... A new audio analysis-based detection method is put forward in this paper to detect avian influenza as early as possible. Because a distinctive difference exists in the short-time auto-correlation functions of recorded chicken sound and ambient noise, the former can be extracted from the record and the latter discarded. The mel-frequency cepstral coefficients (MFCC) are determined by analysing and ...

Abstract:
... Improvements in living standards have resulted in consumers having higher expectations for chicken meat quality. This is particularly true in Asia, where there is high consumer preference for local breeds. Nothing is presently known about the effectiveness of using genomic selection (GS) strategies in chickens to genetically improve meat quality traits that cannot be measured in living potential p ...

Recently, the blue‐breasted quail (Coturnix chinesis), the smallest species in the order Galliformes, has been proposed as an excellent candidate model in avian developmental studies owing to its precocious and prolific properties. However, data on the embryonic devel ...
