A great familiarity with the physiology of the systems has permitted the growth of an unique way of semen collection and insemination adjusted specifically to geese (see area on synthetic Insemination). This is certainly somewhat distinctive from the strategy employed for almost every other avian species, e.g. Gallus gallus .
MALE REPRODUCTIVE SYSTEM
FIGURE 12. Reproductive organs associated with gander
The system that is reproductive of gander consist of three distinct components:
There are two main bean-shaped testicles within the human body cavity which create both spermatozoa and male hormones. They have been highly vascularized and alter in size and place relating to perhaps the gander is intimately active or otherwise not. The chronilogical age of intimate readiness for ganders is straight associated with their illumination programme. Nonetheless, spermatozoa manufacturing doesn’t frequently start before the ganders are in minimum 30 months of age. The spermatozoa move to the epididymis from the testicles.
The vas deferens
These (there are two main) stick to the urethras and transport the spermatozoa from the testicles and also the epididymis into the organ that is copulatory. Their obvious size is 15 cm, however they have actually many bends and twists plus in reality measure significantly more than 30 cm. The vas deferenes will be the location of spermatozoa maturation and storage. They terminate during the seminal vesicles found in the cloaca wall surface.
The organ that is copulative
As opposed to your rooster, Gallus gallus, the copulatory organ associated with the gander is extremely ripped. It really is invaginated, spiral-like and it is about 15 cm in total. a furrow that is spermatic across the whole duration of the organ and transports the semen after ejaculation.
