Abstract

The current study aimed at investigating the hypothesis that breeding schemes that adopt Artificial Insemination with sexed semen (AI-XS) could realize higher response to selection compared to an AI scheme of the same size using conventional semen (AI-CS). Data was obtained from literature on dairy cattle production systems both in Kenya and the tropics. The computer program ZPLAN was used to model and evaluate the breeding systems. The simulated population was monitored for a period of 25 years. From the results, the annual genetic gain and returns per cow per year for AI-CS was146.38 and 1384.15 respectively. The AI-XS scheme realized annual genetic gain and returns of 146.38 and 1384.15 respectively. The results clearly indicate that AI-CS and AI-XS realize the same response to selection in terms of genetic gain and returns per cow year. This implies that dairy farmers are better off if they adopt the AI-CS breeding scheme if the objective is to achieve genetic gain.
