this is a sad story. but it has a happy ending. it's about a mother dairy cow who kept hiding her calf.
unfortunately most calfs born to dairy cows have a life expectancy only numbered in weeks. they're separated from their mothers a day after birth and spend most of their remaining days tied to a post or kept in a tiny pen being fattened up so they can be slaughtered for veal. most are only kept alive for 16-20 weeks. and some are slaughtered when a few days old to produce a low-grade veal that's often used in tv dinners.
dairy cows are considered "spent" after less than 5 years on average. these are then "retired" [i.e. slaughtered]. usually for the cheap grade of hamburger meat used by fast food chains.
a cow's life expectancy is about 20 years under normal circumstances
