Dairy Farm

The Dairy Farms are buildings available on FarmVille. This building can be purchased at the market for either coins or FarmVille Cash. However, you need to have at least 8 neighbors to be able to buy one with coins. A Dairy Farm will hold up to 20 - 40 cows (or 19 - 39 cows and 1 bull) and lets a farmer collect from them all at once. A farmer can own up to five Dairy Farms paid by coins, but more can be purchased with 20 cash each. To place a cow in a Dairy Farm, a farmer must select the move option and move the cow to the Dairy Farm. Clicking on the building will put the cow into the Dairy Farm. When a Dairy Farm has 6, 10 or 15 cows inside, a farmer will receive extra fertilizer when fertilizing his neighbor's crops (this happens each time they reach a number).

If a Dairy Farm contains a bull, then every time milk is collected there is a chance that there will also be a Baby Calf produced. The odds of producing, for example, a Pink Calf are slightly higher if all the pink cows are in a single Dairy Farm, instead of spread among several. The Dairy Farm can now also hold Referee Cows.

Expanding
Dairy Farms can now be extended after the June 21st update. Dairy Farms are extendable,, first to 30, then to 40 cows. The procedure is similar to a barn raising. Extension of dairy farms causes 1 milk jug to appear on the side per extension. If you have 5 Dairy Farms, the total cows that you can put in the Dairy Farm is 200 cows.
