Antecaca

Antecaca- The first defecation made by a "milking cow" immediately after being milked. The term came about in the late 18th century when a dairymen in Pennsylvania wrote a short editorial on his observation that most of his cows would defecate soon after being milked out. The observation was widely noted thereafter, and the term, antecaca, became the named standard. It is believed, though little research has been made, that the pressure from the udder of a cow once relieved by a milking shrinks so that the colon of the cow then relaxes. This in turn promotes an antecaca. Antecacal defecations have been recorded in 82.5% of all dairy cows within 3 minutes of being milked. This is why in many states it is illegal to use a milk cow, in lactation in a cow plop bingo, as the owner of the cow could give an unfair advantage in the gambling event. Holsteins, Milking Shorthorns and Ayshires are the three breeds most likely to have an antecaca. Guernseys are almost never known to have an antecaca, largely believed because the unique carotene of their "Golden Guernsey" milk is a soothing agent for the milk glands and surrounding viscular tissue. Thus the relief from a milking is not as tangible as in other breeds.
