Abstract

Early attainment of puberty in dairy heifers is critical for improving reproductive efficiency and ensuring sustainable dairy production systems. This study explores targeted management practices that can accelerate puberty onset, contributing to enhanced productivity and economic viability in dairy farming. Key factors influencing puberty in heifers include nutritional management, genetic potential, health care, environmental factors, and behavioral interventions. Adequate nutrient supply, especially energy and protein, along with balanced mineral and vitamin supplementation, plays a pivotal role in ensuring optimal growth rates and hormonal regulation. Stress-free housing environments, proper photoperiod management, and controlled exposure to social interactions further enhance reproductive maturity. Health care interventions, such as timely deworming and vaccinations, coupled with regular monitoring of body condition and growth parameters, also contribute significantly to advancing puberty. Additionally, innovative practices, such as precision feeding and environmental control, address the challenges associated with climatic stress and resource optimization. This review synthesizes recent advancements in understanding the physiological and management aspects of puberty in dairy heifers, offering practical solutions to overcome associated challenges. The study emphasizes the need for integrative approaches combining nutrition, management, and genetics to achieve sustainable development in dairy farming while improving the overall efficiency and welfare of dairy heifers.
