Comparative Reproductive Performance of Dairy Cows and Buffaloes

Abstract

Dairy cattle (Bos taurus and Bos indicus) and water buffaloes (Bubalus bubalis) are important contributors to global milk production, food security, and rural livelihoods. However, differences in reproductive physiology, endocrine regulation, environmental adaptation, and management practices influence their reproductive efficiency and lifetime productivity. This review comparatively examines the reproductive performance of dairy cows and buffaloes, with particular emphasis on age at puberty, estrous cycle characteristics, follicular dynamics, postpartum reproductive recovery, and conception outcomes. Although both species share fundamental reproductive mechanisms, buffaloes commonly exhibit less conspicuous estrus, greater seasonal variation in reproductive activity, and delayed puberty under suboptimal nutritional and management conditions. Conversely, reproductive performance in dairy cattle is frequently compromised by metabolic stress associated with high milk production, postpartum negative energy balance, and heat stress. In both species, postpartum anestrus, uterine disorders, ineffective estrus detection, suboptimal insemination timing, and early embryonic mortality contribute to reduced fertility and prolonged calving intervals. Advances in reproductive ultrasonography, hormonal synchronization, timed artificial insemination, activity-monitoring systems, and emerging precision livestock technologies offer opportunities to improve reproductive management. Nevertheless, their effectiveness depends on species, breed, physiological status, season, nutrition, and farm management. Future research should prioritize comparative studies, validated fertility biomarkers, optimized synchronization protocols, climate-resilient reproductive strategies, and the application of genomic and epigenetic approaches to improve reproductive resilience. Overall, integrating reproductive biotechnology with appropriate nutrition, environmental management, and systematic fertility monitoring is essential for sustainable improvements in cattle and buffalo reproduction. Species-specific, evidence-based management strategies are therefore preferable to uniform reproductive interventions across different dairy production systems.
