Abstract

The dependence of the linear osteometric parameters of cattle’s mandible on the age and sex of the animal has been studied. It has been shown that in regression analysis should to apply two nonlinear third order regression functions from the linear osteometric parameters of mandible: first for sub-threshold period (from birth to threshold criterion) and second for above-threshold period (from threshold criterion to before the deadline for research). The coefficients of determination for a combined equations of regression exceed the value R2 = 0,998, and the standard error of the of the animal’s age is within 3,27 months for the whole age range. The value of threshold age criterion is more for females than for males of cattle. To determine the age and sex of animals can be within the standard error of regression from several values of (at least two) mandible body measurements.
