The primary emphasis in dairy cattle selection is for yield traits because highest producing cows usually are more profitable. Selection on yield traits alone could decrease merit for other traits. Selection on type traits associated with increased herd life may be benefical to decrease involuntry culling and increase profitability. One of the primary reasons for collecting and utilizing information on type is to aid breeders in selecting profitable, functional cows. So that early culling for causes unrelated to yield (involuntry culling) can be avoided [Misztal et al, 1992]. The objectives of the present study were to evaluate the effects of some environmental factors on and to estimate genetic parameters of some type traits.
