equine embryology

Equine embryology is the study of how a horse's embryo develops from fertilization to the beginning of pregnancy. It starts with the fusion of sperm and egg, forming a zygote that divides rapidly as it travels through the fallopian tubes. The cells then organize into layers, establishing systems like the nervous and circulatory systems. By about 14 days post-fertilization, the embryo attaches to the uterine wall, initiating pregnancy. Understanding this process helps in managing horse breeding, detecting pregnancy, and ensuring proper development during early gestation.
