Modify Wideband Emissions: Modify licenses to narrowband emissions on frequencies that only have wideband emissions. Remove Wideband Emissions: Modify narrowband-compliant licenses to only remove wideband emissions. These are transition licenses with frequencies that have both a wideband and narrowband emission.
On a daily basis, most cows average about 70 lbs. of milk per day, or about 8 gallons per day. 8 gallons is about 128 glasses of milk per day. Interestingly, a herd of 800 cows can produce a large tanker truckload of milk each day.
It totally depends on the breeds of cows used for milking. Dairy cow milk yield has increased from an average of 3,750 litres per cow per year (12 litres/21 pints per day) in the 1970s to 7,445 litres (24.5 litres/42 pints per day). One of the highest yielding cow breed is Dutch Holstein Friesian cows.
