I have looked into this a lot and there is no answer anywhere on the internet for your question but it does happen that i live on a farm in jersey and we get around 2467L of milk from approximately 58 cows.
Holstein cows produce an average of 3.5% butterfat with an average of 17,000 pounds of fluid milk per year. That would be 595 pounds of butterfat per year. Holsteins are the highest total fluid milk producers, but are on the low side of percent butterfat and percent protein. Even so, if you compare Holsteins to breeds that produce higher butterfat (like Jerseys and Guernseys), the Holstein will produce more total butterfat in a year due to the higher volume of fluid milk that they produce.
A typical Jersey would produce around 15 kg (~4 gal.) of milk per day on good feed and pasture. A typical Jersey cow will produce 5000 kg per year (or 1319 gal per year).
Not much after this past year.
5,000 Litres per year
7billion a year
A Superior Court judge in New Jersey earns about $165,000 per year.
not much mate.
around 10 billion

None.
A year old Jersey steer typically weighs between 400 to 600 pounds, depending on genetics, diet, and overall health.
Not as much as he would do nowadays, but I would say around 2 million a year.
