A TMR diet achieves a wide distribution of nutrients in uniform feed rather than switching between several types. A cow's ration should include good quality forages, a balance of grains and proteins, vitamins and minerals. [1]
This is because feeding grain to cattle makes their normally pH-neutral digestive tract abnormally acidic; over time, the pathogenic E. coli becomes acid resistant. [40] If humans ingest this acid-resistant E. coli via grain-feed beef, a large number of them may survive past the stomach, causing an infection. [41]
In 1997, in response to outbreaks of Bovine spongiform encephalopathy, commonly known as mad cow disease, the United States and Canada banned a range of animal tissues from cattle feed.

Since cattle are herbivores and need roughage in their diet, silage, hay and/or haylage are all viable feed options.

[15] Cattle weighing 1000 lbs. will drink an average of 41 L a day, and approximately 82 L in hot weather. [16]
