Heifer Fundamentals is a chapter from the book Raising Dairy Replacements.
The primary focus of rearing heifers is to grow and develop heifers as quickly and cost effectively as possible without negatively influencing animal health and lifetime productivity. When developing heifer management plans, it is important to understand key management concepts such as heifer growth, mammary development, puberty, calving age, and body weight at calving.
