Ruda S. Selection and genetic features of mini-chikens with different performance directions

The research object. Process of forming of productive qualities of different population chicken and genetic changes which take place at their breeding. Subject of the research. Egg productivity, living mass, mass of eggs, reproductive ability, selection-genetic parameters of of the main economically valuable traits, mini-chicken genetic structure, economic efficiency of their breeding. The research methods. Zootechnic, generalization and systematizations, immunogenetic, electrophoretic, populational-genetics and statistical, economic. Scientific novelty of the results. The selection-genetics characteristics of meat-eggs mini-chickens of domestic selection were defined Firstly in Ukraine, their reproductive qualities, morphological composition of eggs were investigated. The practical importance of the results. Usefulness of applying the meat-eggs mini-chickens as a parent form for the egg-meat and meat-egg productivity hybrids was determined.
