Contributions to Knowing the Neural Tube Development
Abstract
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 until now. Plymouth Rock breed was imported for the first time to Romania from the Studler Company, France in 1969. This paper is aiming to perform a profound analysis of the development patterns of the neural tube in the two breeds, by measurements carried out at 30, 40, 50, and 60 hours of incubation. Observations show that the closure of the neural canal and its transformation into a tube follows an undulatory pattern, of which positive and negative curls are diametrically opposed in the two breeds, while the development speed during the whole studied period have a relative similar value between the two breeds. 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.
