We used deterministic simulation to investigate hypothesis that breeding schemes that adopt Multiple Ovulation and Embryo Transfer (MOET) with X-sorted semen could realize high response to selection compared to an AI scheme of the same size. We used a breeding scheme resembling that of dairy cattle in Kenya to investigate this hypothesis. The response to selection in each scheme was computed and compared based on monetary annual genetic gain, returns, costs and profitability per cow per year. The findings confirmed our hypothesis, as the MOET scheme realized annual genetic gain, returns, profitability per cow per year of KES 710.82, 2781.23 and 2568.52 compared to corresponding values of 410.68, 2470.20 and 2384.98 in AI scheme. The high response to selection in MOET scheme was attributed to increased reproductive rate in both sexes resulting to high intensity and accuracy to selection. The findings of this study demonstrates that, even though MOET scheme had high costs of production, the returns could cover the costs and result in high profitability than when X-sorted semen is used in an AI scheme. Key words: conventional semen; sexed semen; reproductive technologies
