Insemination

 

Ovary in Post-oestrus

At the start of post-oestrus, the follicle bursts. The egg is collected by the funnel-shaped end of the oviduct. After insemination, the sperms also migrate via the uterus to the oviduct, where they encounter and fertilise the egg. Within 4 to 7 days, the fertilised egg (zygote) passes through the oviduct into the uterus, where it embeds in the mucous membranes (endometrium).
