The onset of puberty in dairy heifers is a critical determinant of their reproductive performance and overall productivity. This study reviews the influence of weaning age on the timing and quality of puberty, synthesizing insights from nutritional, physiological, hormonal, and environmental perspectives. Early or late weaning can significantly impact heifer development, influencing body weight, fat deposition, and metabolic health. Nutrition plays a vital role in shaping growth rates and reproductive readiness, with optimal nutrient intake during key growth phases facilitating earlier puberty. Physiologically, weaning age can affect hormonal profiles, particularly levels of insulin, leptin, and growth hormone, which are crucial for the initiation of reproductive processes. Furthermore, environmental factors, including housing conditions, temperature, and social interactions, also modulate stress responses that may delay or advance puberty. Understanding the multifaceted relationships between weaning age and puberty can inform management strategies aimed at optimizing heifer development, ultimately enhancing dairy farm productivity and sustainability. This review underscores the necessity for integrated approaches that consider the interplay of various factors in establishing best practices for heifer management.

Keywords: Dairy heifer, environmental factors, hormonal regulation, management practices, nutritional strategies, puberty onset, sustainability, weaning practices
