|Before breeding, make sure that your heifers have reached four important milestones.|
Not sure when to start breeding heifers? Jose Santos, dairy nutritionist at the University of Florida, says heifers should achieve these milestones before you start breeding them:
Sexually mature, with two or more estrous cycles completed since puberty.
At least 12 months of age.
Have attained 55 percent to 60 percent of mature body weight. In
Holsteins, that is about 800 pounds.
Have achieved adequate frame size. In
Holsteins, this equates to a wither height of about 49 inches.
