Sixteen bitches were artificially inseminated with either fresh, 24 h-chilled or 48 h-chilled extended semen over 38 estrous cycles. A commercial system for extending, chilling and transporting semen commonly used in the equine industry was used Pregnancy rates and litter sizes of the bitches inseminated with extended, chilled semen (19/20, 95%; litter size = 7.1) were not significantly different from those observed in bitches inseminated with fresh semen (17/18, 94%; litter size = 7.2; P > or = 0.89). These results show that a commercial system for extending, chilling and transporting equine semen is an attractive and efficient method of shipping canine extended chilled semen.
在38个发情周期内，对16只母犬分别用新鲜精液、保存24小时的冷冻精液或保存48小时的冷冻精液进行人工授精。采用了一种在马业中常用的用于精液稀释、冷冻和运输的商业系统。用稀释后的冷冻精液授精的母犬的妊娠率（19/20，95%；窝产仔数 = 7.1）与用新鲜精液授精的母犬（17/18，94%；窝产仔数 = 7.2；P≥0.89）相比，差异不显著。这些结果表明，一种用于马精液稀释、冷冻和运输的商业系统是运输犬冷冻稀释精液的一种有吸引力且高效的方法。
