Abstract
An attempt has been made to categorize the various factors that may influence the fertility of a dairy herd.
This broad categorization comprises environmental and managerial conditions, managerial factors as such and genetic conditions.
A closer examination of these factors reveals that they seldom exert their influence individually but, rather, in an interacting fashion, making it difficult to identify a single factor for fertility failure.
It is mentioned that, under certain environment and management conditions, management usually falls short. It is advocated therefore, that these failures should be prevented by advising the dairyman, during regular visits (Herd Fertility Programme), so that he will focus his attention on his management practices.
