The spiral colon, despite its similarity in ovine and bovine species is only the site of pellet formation in sheep. This peculiarity is associated with a permanent and localized contractile activity of the ovine spiral colon instead of 5-min periods of continuous activity migrating slowly aborally in cattle.
螺旋结肠,尽管在绵羊和牛的物种中相似,但仅在绵羊中是粪粒形成的部位。这种特殊性与绵羊螺旋结肠的永久性局部收缩活动有关,而不是像牛那样有持续5分钟的活动并缓慢向口侧迁移。
