Equine and human chorionic gonadotropins were administered to two female Amur leopard cats to induce estrus and ovulation during non-breeding season. Fresh semen collected from male cats was surgically inseminated into the uterine horn of the females. In one animal, two fetal sacs without heartbeats were observed on abdominal ultrasonography 31 days after insemination, which indicated that embryo death had occurred. In the other animal, fetal heartbeats were detected in two fetal sacs 29 days after insemination, which confirmed as pregnancy. This animal delivered two newborns 68 days after insemination; the one of the kittens was assumed to be stillbirth, and the other grew normally. In this study, we successfully obtained a kitten from an Amur leopard cat by artificial breeding for the first time in Japan.
在非繁殖季节，给两只雌性豹猫注射马绒毛膜促性腺激素和人绒毛膜促性腺激素以诱导发情和排卵。从雄性猫收集的新鲜精液通过手术授精到雌性猫的子宫角。在一只动物中，授精31天后腹部超声检查发现两个没有心跳的胎囊，这表明胚胎已经死亡。在另一只动物中，授精29天后在两个胎囊中检测到胎儿心跳，证实怀孕。这只动物在授精68天后产下两只新生幼崽；其中一只小猫被认为是死产，另一只正常生长。在本研究中，我们首次在日本通过人工繁殖成功地从一只豹猫获得了一只幼崽。
