摘要

Transcervical artificial insemination (AI) after the surgical incision of cervical folds (SICF) could represent a valid alternative to laparoscopic AI when frozen thawed semen is used. The aim of this experiment was to compare pregnancy (PR) and lambing rates (LR) of ewes submitted either to transcervical AI after SICF or to laparoscopic AI using frozen thawed semen. Pregnant at term ewes (n = 80) were allocated in two experimental groups. After lambing, one group (n = 39) was submitted to SICF. The remaining ewes that were regularly lambed were allocated to the group of laparoscopic AI (n = 40). Six months later, oestrous cycle of both experimental groups was synchronised and all ewes were artificially inseminated with frozen thawed semen. Ewes submitted to SICF underwent transcervical insemination and intrauterine deposition of semen was recorded. The remaining animals were submitted to laparoscopic AI. Pregnancy and LR were recorded. Intrauterine deposition of semen was possible in 89.7% pf ewes submitted to SICF. This group showed similar PR and LR compared to the laparoscopic group (respectively: PR, 71.8% vs. 70% and LR, 64.1% vs. 65%; p > 0.05). Transcervical AI after SICF may represent a valid alternative to laparoscopy in AI protocols requiring the use of frozen thawed semen.

宫颈折叠手术切口（SICF）后的患者人工授精（AI）可以代表使用冷冻解冻精液时腹腔镜AI的有效替代物。该实验的目的是将在SICF或使用冷冻过滤精液后的腹腔镜AI进行复晶AI的妊娠（PR）和罕见的母羊和乳液）（LR）进行比较。在两种实验组中分配术语EWES（n = 80）的怀孕。羔羊后，将一组（n = 39）提交给SICF。定期乳纸的剩余母羊分配给腹腔镜AI（n = 40）组。六个月后，两种实验组的令人烦恼的循环被同步，所有母羊都会用冷冻解冻的精液人工苗。记录了对SICF进行的经过诊断的经晶级授精和宫内沉积精液的母羊。剩下的动物被提交给腹腔镜ai。怀孕和LR被记录。在提交给SICF的89.7％PF母羊中，可以进行精液的宫内沉积。该组与腹腔镜组（分别：Pr，71.8％与70％和LR，64.1％vs.65％）显示了类似的PR和LR; p> 0.05）。 SICF后的血管晶状体AI可以代表需要使用冷冻解冻精液的AI协议中的腹腔镜检查的有效替代物。
