The pygmy hog (Porcula salvania), until recently was classified as a critically endangered suid facing the threat of extinction due to habitat degradation. Efforts are being made to protect the pygmy hog from extinction and breed them in captivity under the Pygmy Hog Conservation Programme (PHCP). However, very little information is available on the reproductive physiology of pygmy hogs. Therefore, the present study aims to standardize enzyme immunoassays (EIAs) for monitoring pregnancy and reproductive status using progesterone and testosterone metabolites. A total of 785 fecal samples were collected from five females and two males over a period of one year from the PHCP Research and Breeding Centre, Guwahati, Assam. High-pressure liquid chromatography (HPLC) analysis revealed the presence of immunoreactive progesterone and testosterone metabolites in feces. Mating was observed in all five females, and four of them gave birth successfully. We were able to detect pregnancy using fecal progesterone metabolites. The mean gestation period, based on mating and parturition, was estimated to be 153.25 days from the four females studied. The breeding center recorded 172 births between 1996 and 2000 and found strong seasonal patterns in the birth rate, with most of the births occurring between May and June. In the males, fecal testosterone metabolites were significantly higher in the breeding season than in the non-breeding season. This is the first study on the subject and will help with future breeding programs in other captive breeding centers and with reproductive monitoring of reintroduced populations.

濒临灭绝的侏儒猪(Porcula salvania)的非侵入性生殖激素监测

侏儒猪(Porcula salvania),直到最近才被归类为因栖息地退化而面临灭绝威胁的极度濒临灭绝的suid。根据“ y格米养猪计划”(PHCP),人们正在努力保护py格米猪免于灭绝,并圈养它们。但是,关于侏儒猪的生殖生理的信息很少。因此,本研究旨在标准化利用孕激素和睾丸激素代谢产物监测妊娠和生殖状况的酶免疫测定法(EIA)。在一年的时间里,从阿萨姆邦古瓦哈提的PHCP研究与育种中心收集了785份粪便样本,其中包括5名雌性和2名雄性。高压液相色谱(HPLC)分析显示粪便中存在免疫反应性孕酮和睾丸激素代谢产物。在所有五名女性中均观察到交配,其中四名成功分娩。我们能够使用粪便孕酮代谢物检测怀孕。根据所研究的四名女性,基于交配和分娩的平均妊娠期估计为153.25天。繁殖中心在1996年至2000年之间记录了172例出生,并发现出生率呈明显的季节性变化,大部分出生在5月至6月之间。在雄性中,粪便睾丸激素代谢物在繁殖季节明显高于非繁殖季节。这是该主题的第一项研究,将有助于其他圈养繁殖中心的未来繁殖计划以及对再引入种群的生殖监测。我们能够使用粪便孕酮代谢物检测怀孕。根据所研究的四名女性,基于交配和分娩的平均妊娠期估计为153.25天。繁殖中心在1996年至2000年之间记录了172例出生,并发现出生率呈明显的季节性变化,大部分出生在5月至6月之间。在雄性中,粪便睾丸激素代谢物在繁殖季节明显高于非繁殖季节。这是该主题的第一项研究,将有助于其他圈养繁殖中心的未来繁殖计划以及对再引入种群的生殖监测。我们能够使用粪便孕酮代谢物检测怀孕。根据所研究的四名女性,基于交配和分娩的平均妊娠期估计为153.25天。繁殖中心在1996年至2000年之间记录了172例出生,并发现出生率呈明显的季节性变化,大部分出生在5月至6月之间。在雄性中,粪便睾丸激素代谢物在繁殖季节明显高于非繁殖季节。这是该主题的第一项研究,将有助于其他圈养繁殖中心的未来繁殖计划以及对再引入种群的生殖监测。繁殖中心在1996年至2000年之间记录了172例出生,并发现出生率呈明显的季节性变化,大部分出生在5月至6月之间。在雄性中,粪便睾丸激素代谢物在繁殖季节明显高于非繁殖季节。这是该主题的第一项研究,将有助于其他圈养繁殖中心的未来繁殖计划以及对再引入种群的生殖监测。繁殖中心在1996年至2000年之间记录了172例出生,并发现出生率呈明显的季节性变化,大部分出生在5月至6月之间。在雄性中,粪便睾丸激素代谢物在繁殖季节明显高于非繁殖季节。这是该主题的第一项研究,将有助于其他圈养繁殖中心的未来繁殖计划以及对再引入种群的生殖监测。
