This all depends on what country, state or province you're referring to. Some areas have more dairy farms than beef farms, other places it's the other way around.
In terms of popularity in North America though, beef cattle farms are more popular than dairy.
Both are, though the dairy industry seems to be more popular than the beef industry, but probably only by a margin.
Dairy.
There are under 13, 000 dairy farms in New Zealand. See related link below for more info.
Dairy cattle
Mainly beef, however, more farms are beginning to use Shorthorns for dairy production.
Both (they drink milk there as well as eat beef) but there are more beef cattle.
Yes they definitely are. They have a more pronounced masculinity about them than beef bulls do because of the extreme selection for more maternal and milking traits in the dairy females.
Dairy cattle require more higher nutritive feeds than beef cattle do, and so need to be raised in an area where these higher nutritive feeds can be raised and fed to them. Dairy farms are located on or near the "corn belt" or an area of land on the North American continent where crops can grow and have high quantity and quality yields. Pastures in this area where some dairy farms allow their cows and heifers to graze during the summer months (or those months where grass grows the lushest) also need to have this high quantity and quality of grasses. The area also needs to be level and flat enough that barns and silos can be built and that are easily accessible to farm equipment used on the dairy farm. Beef cattle, on the other hand, are raised in areas where they are on pasture all the time and do not require much human input. Beef cattle can be raised in areas where dairy cattle are raised, or in much more rougher terrain like down in the desert of southern California, Nevada, Arizona, New Mexico and West Texas. Beef cows have a much lower nutritive requirement to thrive and feed a calf than dairy cows do, and so are much more flexible where they can be raised.
Charolais are the worst breed you can think of for dairy purposes! They are a beef breed, not a dairy breed. When they were originally developed they were used for milk, but they were found to be more suitable for being raised for beef and a draft animal than for dairy production. Charolais cows don't give much milk anyway.
Dairy cows have larger udders than beef cows, are typically a bit thinner, and tend to have a less blocky appearance than most beef cows. Dairy cows also have more feminine characteristics to them than beef cows do.
No. The biggest type of bovine is typically the beef cow. There are beef cows around that weight more than a big dairy cow, and that can be upwards of 2000 lbs or more.
To grow food for people, milk wheat and product used to make more products beef cows make beef there is a HUGE list of things farms can be used for
