Behavioral analyses constitute a logical starting point for discerning
the causes of reproductive failure in captive mammals and should be c
ompleted before moving on to more invasive diagnostic procedures. Beha
vioral inadequacies affecting reproductive performance may be attribut
able to deficient early rearing environments, to the social milieux in
which breeding-age animals are held on a longterm basis, or in the wa
y pairings for mating are staged. Diagnoses may be focused on uncoveri
ng motivational, motoric, social, or communicative deficiencies. A bio
logically based approach which integrates species-typical behavior wit
h concerns for genetics, physiology, and health in designing breeding
programs will improve prospects for success. (C) 1994 Wiley-Liss, Inc.
