19 Changes in skull proportions of cattle during ontogeny LÁSZLÓ BARTOSlEWICZ OSSA Ontogenetic changes were studi ed in 21 cattle /Red Pied Hungarian/ skulls from a museum sample. A previously developed system of 14 cranial measurements was used. The differen- tial growth of skull measurements was descrihed with allometric equations. The results have shown that the main skull dimensions do not change significantly relative to one another, whi le the halance of the head is in continuous interaction wi th the strong changes in the viscerocra- nia 1 region. Differential growth could be observed not only between parts wi th different functions but also in the longitudinal planes of the head.

ISSN 0345-8865 Received June 5, 1980 Introduction While the heyday of craniometric investigations was in the last century, almost a ll detailed ontogenetic studies began in the first half of this century. The gene ra 1 theories of growth and development, all required the existence of more advanced scientífíc methodology and more adequate tools of evaIuation. It was the research of Brody (Br'ody, 1927), Schmalhausen (SchmaIhausen, 1928), and Hammond (Hammond, 1952) among others, which developed into fundaments in the fieId of growth theory. Correlations of linear growth were demonstrated for seve- ral species. Brody' s calculations were particularly noteworthy in this consideration describing the differential growth of bodymass and line ar measurements of cattle (Brody, 1945). This study is based on the connection of craniometry and of growth studies. The two disciplines were often synthetised within the framework of genetic studies con- cerned with inter- and intraspecific phaenoanalyses of several species (Fábián, 1959, 1969a; Széky, 1969).
