*The mammary gland in the domestic species can be likened to an inverted bunch of grapes i.e. a cluster of secretory acini connected by a duct system to the teats.  

The mammary gland in the domestic species can be likened to an inverted bunch of grapes i.e. a cluster of secretory acini connected by a duct system to the teats. In the cow and ewe the major lactiferous ducts empty into a single teat cistern which drains through one teat orifice (the streak canal). The solitary nature and integrity of the lining of the streak canal are very important in relation to the genesis of infective mastitis in the cow and ewe. In the mare, sow, bitch and queen several (2-20) ducts open through each teat.
