There are fine hairs on the teats. Blood and lymph systems are similar to the cow's. Horses Glands are located in the inguinal region. Blood and lymph systems are like a cow's. There are two teats that are flat, broad and blunt, each with two streak canals and two teat cisterns, and each leading to a separate gland.
Glands are in two parallel rows, one on each side of the ventral midline.
They may or may not be spatially paired. The number on each side may be even or odd. Each simple gland is separate, that is the secretory tissue is independent from the adjacent gland. Also, there is little relationship between teat number and maternal performance. Nevertheless, gilts are still chosen for breeding based partially on the number of teats.
