Over the next three months of the second trimester, more major development occurs for the fetus to differentiate between dairying and beefing breeds. Develop coat color patterning and horns if applicable.

Finally, rapid growth continues in the third trimester from 6-9 months old. And birth weight is reached before milk production begins in anticipation of the cow’s birth.
