CONTRIBUTIONS TO KNOWING THE SEGMENTED MESODERM DEVELOPMENT IN TRANSYLVANIAN NAKED NECK BREED
Keywords:
mesoderm segmentation, embryos, Transylvanian Naked Neck, Plymouth RockAbstract
In Romania, the Transylvanian Naked Neck hen breed is considered to be an
“endangered” population, reason for which we consider that a special attention
should have been given then until now. Plymouth Rock breed was imported for the
first time to Romania from the Studler Company, France in 1969. The present work
is aiming to study profoundly the development model for development at 26, 30, 40,
50 and 60 hours incubation age, in Transylvanian Naked Neck hen breed and
compare it to Plymouth Rock breed. The observations are proving that in the first 60
incubation hours the segmented mesoderm morphogenesis in the two breed, is
different, dictated by the two different genetic structures. It is noticeable that
Transylvanian Naked Neck is characterized by a vigorous embryonic development,
overcoming, the other breed tested by the age of 40 incubation hours. We estimate
that the two breeds have a good combinative capacity, which recommend the
utilization of these genetic materials to obtain hybrids for producing “peasant-type”
chicken meat, very well-appreciated by the Europeans between the two World Wars.
