The reproductive tract of a mare is suspended by the broad ligament. If you're a veterinarian in training, or just curious of the anatomy of the female equine reproductive tract, then these two video dissection tutorials are for you.
You'll see the mesometrium is the mesentery of the uterus. It constitutes the majority of the broad ligament of the uterus, excluding only the portions adjacent to the uterine tube and ovary. You'll see the mesovarium of the horse, which is the portion of the broad ligament of the uterus that covers the ovaries. And you'll see the mesosalpinx, which is the portion of the broad ligament that stretches from the uterine tube to the level of the ovary of the horse.
