The main achievements of the scientific activity of the Laboratory of Biochemical Bases of Wool Formation during the period of its existence, for 42 years (1970–2012) are presented. It is shown that during this period the laboratory developed the theoretical basis of wool formation processes, which are based on the identified patterns of relationship between the level and direction of metabolic processes in sheep, especially in the skin, with morphogenesis, structure, chemical composition and physical characteristics of wool. The research results have been widely published in various scientific journals, including foreign ones (more than 700 articles). 13 monographs and manuals, 23 methodical and one practical recommendations, several information communiqué were published, 34 dissertations were defended, including five doctoral dissertations. Scientific developments are protected by copyright certificates (five certificates) and patents of Ukraine.
