Biogenetically related groups of rare geese breeds
Authors studied the genetic parameters of the reproductive traits (mortality, egg production, egg weight, egg fertility and hatchability, hatch of goslings) in geese depending on breed and bloodline. The original analysis of these traits in biogenetically related groups of breeds was performed. The comparative study of 21 breeds showed that the reproductive efficiency in a group of several breeds (marked as the 1st bloodline) related to the common ancestral breed (Chinese Brown) was higher in compare to other breeds and groups of breeds studied. The data of this analysis will be used for the advancement of conservation programs for these rare breeds.
