Semen collected from wapiti (Cervus elaphus) in Canada in 1983 was frozen in two extenders. In 1988, the semen was used to inseminate 200 red deer hinds on 2 farms in New Zealand. Oestrus was synchronized in the hinds with progesterone-impregnated intravaginal devices (CIDR); 200 iu pregnant mares' serum gonadotrophin was given to each hind on Day 11. The CIDRs were removed on Day 12 at 20/h, as the numbers of the hinds were recorded. On Day 14, 54-56 h after CIDR removal, the hinds were brought into the yards in the same batches and laparoscopically inseminated. Semen from three sires was used. The overall conception rate was 51%. Gestation length ranged from 239 to 247 days. One hind was lost at calving, 3 calves had to be hand raised and there were 2 neonatal calf deaths.
1983年从加拿大马鹿（Cervus elaphus）采集的精液用两种稀释液冷冻保存。1988年，这些精液被用于给新西兰两个农场的200头母鹿输精。用含孕酮的阴道内装置（CIDR）使母鹿发情同期化；在第11天给每头母鹿注射200国际单位的孕马血清促性腺激素。在第12天以每小时20头的速度取出CIDR，并记录母鹿数量。在取出CIDR后的54 - 56小时，即第14天，将母鹿按批次赶入围场，通过腹腔镜进行输精。使用了来自三头种公鹿的精液。总体受胎率为51%。妊娠期为239至247天。产犊时有一头母鹿死亡，3头犊牛需要人工饲养，还有2头新生犊牛死亡。
