METHOD FOR DETERMINING THE AGE AND SEX OF CATTLE BY OSTEOMETRIC PARAMETERS OF NASAL AND BACKSKULL SECTION

摘要

A method for determining the age and sex of the cattle by osteometric parameters of nasal and backskull section comprises cleaning the same from soft tissue, performing osteometric measurement of linear bone parameters and calculation of absolute values ​​of the animal's age according to the equation of nonlinear regression of the 3 order, carrying out osteometric measuring of nasal and backskull section linear parameters and calculating, based on absolute values there​​of, the age of animals of both sexes at the same time, and then, by comparing the age calculation results for several skull measurements, a final expert opinion is made on the age and sex of the animal.
