abstract
The adoption of sex-sorted semen technology has emerged as a promising reproductive intervention for dairy farmers seeking to improve herd productivity, genetic progress, and economic sustainability. For smallholder dairy farms, where financial margins are narrow and investment decisions are highly sensitive to risk, the cost-benefit implications of using sex-sorted semen remain a critical determinant of adoption. This research presents a structured cost-benefit analysis of using sex-sorted semen for improving conception outcomes in smallholder dairy production systems. The analysis considers both direct costs, including semen procurement, handling, and insemination expenses, and indirect benefits such as improved female calf output, enhanced herd replacement efficiency, and long-term gains in milk productivity. Particular emphasis is placed on conception rate variability, which strongly influences economic returns and farmer perceptions of technology viability. The research synthesizes empirical findings from prior reproductive and economic studies to evaluate scenarios under varying conception probabilities and management conditions. Results indicate that although sex-sorted semen entails higher upfront costs compared with conventional semen, these costs can be offset when conception rates are maintained within an optimal range and female calf survival is high. The economic advantage becomes more pronounced in systems prioritizing herd expansion, selective breeding, and reduced dependency on external heifer purchases. Sensitivity analysis further demonstrates that improvements in heat detection accuracy, insemination timing, and overall reproductive management significantly enhance benefit-cost ratios. The findings suggest that sex-sorted semen can be economically viable for smallholder dairy farms when integrated with sound management practices and targeted breeding objectives. This research provides evidence-based insights to support informed decision-making by farmers, extension personnel, and policymakers aiming to promote sustainable reproductive technologies in smallholder dairy systems.
