Abstract
The population generation matrix method has been used to study the growth of female population in Indian dairy herds. Explicit expressions for the elements of generation matrix in terms of the parameters defining the scheme of selection and vital characteristics of a dairy herd have been derived. Two different approaches for controlling the strength of a herd which is changing over time have been suggested. The theory developed has been illustrated with the help of actual data from five Indian dairy herds.
