The effect of insemination interval, semen dose and dilution on fertility was investigated. Good fertility was obtained with twice-weekly insemination using 0.01 to 0.05 ml undiluted semen, 0.03 to 0.05 ml semen diluted 1:1 or 0.04 ml semen diluted 1:3, and also with weekly insemination using 0.04 ml undiluted semen. Fertility showed a downward linear trend with dilution and a curvilinear trend with dosage, for all frequencies.
