Milking cows: Now that nearly all cows are housed fulltime and eating silage, milk yield has dropped significantly on most farms.

Some farmers are considering going once-a-day milking. Generally speaking, the volume of milk drops by 30% when you go to once-a-day milking, but the volume of milk solids drops by 20% as fat and protein percentage increases. So if you’re doing 1kg MS/cow/day on twice a day, you’ll probably do 0.8kg MS/cow on once a day.
