Comment Re:Cows eat Grass (Score 1) 432
Cows did not evolve to eat grass. Cows are adapted to eating a variety of feedstuffs -- the rumen bacteria can break down many things and convert them into rumen bugs which slide out of the rumen and down the line where they are digested. Cows in a state of nature run away from humans. Modern domesticated cows rely on humans to provide them with food. Cows in a state of nature produce a calf a year and are subject to predation and disease which help to keep the population from exploding. Modern livestock agriculture ensures that more calves will survive and that the cows will survive longer. Some are retained in the herd while others -- especially the males -- aren't needed so they are sold as veal calves (from dairy cows mostly) or as feeder calves (from beef breeds) and those calves are fed with an eye toward making money. The only farm I ever saw which varied from this one was the ISKON farm run by the Hare Krishna organization which raised cows for milk and cheese and would not allow any calves to be slaughtered for any purpose. A few of the males were neutered and the oxen used as draft animals. Most of the other males were also neutered -- to make them more docile -- and kept in a separate area where they were feed corn silage and otherwise ignored until they died. At one time they sold the carcases to be processed into meat meal which is used in the manufacture of dog food. Also fed to cows -- until BSE was discovered to be transmissible that way. As for bakery by products including broken cookies with and without chocolate chips, gummy bits, etc. -- they've been fed to cattle for years as have corn distillers grains (high protein, low energy because the starches were turned into alcohol), brewer's grains (similar) and other alternatives. Any feedlot operator (or dairy farm manager) knows about the need to adjust feedstuffs based on what's available -- the computerized ration balancing programs have been around since there were no PC's. The only thing new is that the market for these items is also rising because the demand is up and more farmers have access to ration balancing software.
