We all know that milk goes bad if not refrigerated, but why doesn’t it go bad inside the cow?
<|assistant|>
Milk does not go bad inside the cow because it is naturally preserved by the mammary glands of the cow. As the milk passes through the cow’s first set of mouths, it picks up enzymes and other substances that suppress putrefaction and stop the growth of disease-causing bacteria. These substances also make the milk more palatable to the cow and provide minerals to the calf, helping it to thrive. The exact nature of these agents is still not entirely known, but it is believed they include lactic acid, salts, antibodies, and bacteriophage. In addition, the milk’s high fat content and its transport system help to slow down spoilage as well.
