Abstract: [Objective] To assess the application effects of artificial insemination with frozen semen in cashmere goats production. [Methods] Hanshan white cashmere goats were used as experimental animals and were allocated to trail group and control group. Under grazing condition, the cashmere goats in trail group and control group were artificially inseminated with frozen semen and fresh semen, respectively. The pregnant rate and lambing rate of trail group and control group over the experimental period were statistically evaluated. [Results] In the first estrous cycle, the pregnant rate of trail group (64.99%) was 17.83% lower than that of control group (82.82%, P〈0.01); in the first and second estrous cycles, the pregnant rate oftrail group (83.54%) was 8.62% lower than that of control group (92.16%,P〈0.01); taking the first, second and third estrous cycles into consideration, the pregnant rate of trail group (93.10%) was 3.10% lower than that of control group (96.20%, P〉0.05); no significant differences were observed in lambing rate between trail group ( 105.16%) and control group ( 103.82%, P〉0.05) in the three observed estrous cycles. [Conclusion] By appropriately extending its employment duration in estrous cycles, artificial insemination with frozen semen can achieve comparable application effects in cashmere goats to artificial insemination with fresh semen. Results of this study provide basic data for the promotion and application of artificial insemination with frozen semen in cashmere goats breeding.
