摘要
本研究评估了使用绒毛膜促性腺激素的青春期前后备母猪输卵管安瓿的形态特征。以屠宰日为D0，后备母猪被分配到四个处理（n = 8）：对照组（未处理）、eCG（D3日200 IU eCG）、eCG+hCG（D6日1200 IU eCG加D3日500 IU hCG）和eCG+hCG+AI（前一处理加D1日人工授精）。屠宰时采集血液和安瓿样本。使用 hCG 处理的后备母猪血清孕酮浓度高于 eCG 和对照组（P 0.05）。各处理的上皮、肌肉和管腔面积以及安瓿内径和较大安瓿直径均无差异（p > 0.05）。因此，用绒毛膜促性腺激素处理不会改变青春期前后备母猪的安瓿形态。
Morphometric Evaluation of the Ampullae of the Oviducts in Prepubertal Gilts Treated With Chorionic Gonadotropins.
This study assessed morphometric traits of the ampulla of the oviducts in prepubertal gilts treated with chorionic gonadotropins. With the day of slaughter as D0, gilts were assigned to four treatments (n = 8 each): control (untreated), eCG (200 IU eCG on D3), eCG+hCG (1200 IU eCG on D6 plus 500 IU hCG on D3), and eCG+hCG+AI (the previous treatment plus artificial insemination on D1). Blood and ampullae samples were collected at slaughter. Serum progesterone concentrations were higher for gilts treated with hCG than for those in the eCG and control treatments (p < 0.001), but estradiol concentrations did not differ (p > 0.05). The epithelium, muscle and lumen areas and the inner and larger ampullae diameters did not differ across treatments (p > 0.05). Therefore, treatment with chorionic gonadotropins did not alter the ampullae morphometry of prepubertal gilts.
期刊介绍：
The journal offers comprehensive information concerning physiology, pathology, and biotechnology of reproduction. Topical results are currently published in original papers, reviews, and short communications with particular attention to investigations on practicable techniques.
Carefully selected reports, e. g. on embryo transfer and associated biotechnologies, gene transfer, and spermatology provide a link between basic research and clinical application. The journal applies to breeders, veterinarians, and biologists, and is also of interest in human medicine. Interdisciplinary cooperation is documented in the proceedings of the joint annual meetings.
Fields of interest: Animal reproduction and biotechnology with special regard to investigations on applied and clinical research.
