Male vs Female Guinea Pigs
豚鼠已经成为非常受欢迎的家庭宠物了一段时间。人们不愿从宠物市场购买它们,而是宁愿在房子里繁殖它们。但是,为了进行成功的繁殖过程,知道男性和女性差异将非常有利。但是,通过透过外部形态来验证性别并不是最简单的任务,但是有一些技术可以理解为雄性还是女性。
Male Guinea Pigs
在雄性生殖系统的存在下,应观察到其外生殖器,尤其是阴茎的雄性豚鼠。阴茎不是在豚鼠中放置在体内的,而是在生殖器开口内部,其形状与肛门对外部的形状相似。雄性的生殖器开口是否位于肛门,这有点矛盾,因为许多参考文献都以不同的方式引用。但是,当生殖器周围环境略有压力时,阴茎变得可见。此外,当发生阴囊肿胀时,可以在皮肤下识别睾丸。睾丸可能具有成熟雄性的甜甜圈形状。雄性豚鼠通常比女性生长略多。雄性在笼子的地板上小便,并画了一条尿线以标记自己的领土,这发生在清洁笼子后。这种领土行为在圈养男性中很突出。当他们生活在野生状况时,他们的牛群只有一个男性很少,男性可以与许多女性交配。 Males become sexually matured in about five weeks, and it would be important to know that they emit a deep purring sound during mating with females. The captive male guinea pigs may sometimes have a slight dislike towards the owner. Male guinea pigs are commonly referred as boars, which is the same for the actual pigs.
Female Guinea Pigs
Female guinea pigs are the friendly members of their kind towards the owner when they live as pets. With their likable habits, an adult female (called sow) could be identified with the smaller size compared to an adult male. The location of the genital opening may be slightly close to the anus in the females. A small swelling could be spotted around the genital opening (vagina). One of the most important features in a female guinea pig is the Y-shaped vulvar flaps. The guinea pig sows reach the sexual maturity in about four weeks from birth, and their vagina are remained closed with the membranous hymen until oestrus and parturition. They come to oestrus in every 15 – 17 days and the oestrus lasts up to two days (48 hours). The vulvar region becomes wet during oestrus but seals out otherwise. Sometimes there are instances where the vaginal openings are sealed irreversibly (pubic symphysis), especially in the females that have never been pregnant. Sows do not show aggressive behaviours, but they are very friendly with others including the owner.
