From Bulbapedia, the community-driven Pokémon encyclopedia.
The MooMoo Farm (Japanese: モーモーぼくじょう Moomoo Ranch) is a small farm located on Route 39. Its slogan is: "Enjoy Our Fresh and Tasty Milk". The farm keeps Miltank that produce popular milk for humans and Pokémon. There is a sick Miltank named MooMoo there when the player first arrives. After feeding her several Berries, she will get better and her owner will give the player the TM13 (Snore) (Generation II) or the TM83 (Natural Gift) (Generation IV). After MooMoo is healed, the player can also buy MooMoo Milk.
The MooMoo Farm is a small farm located on Route 39. It contains a small paddock where Miltank graze, a barn house, and another house where the owners live. The paddock is located on the south side of the farm, where four Miltank peacefully graze all day. In the barn, lives a sick Miltank named MooMoo. Two children try to nurse the sick Pokémon, but nothing seems to work. If the player gives MooMoo several ordinary Berries in Generation II, or seven Oran Berries in Generation IV, it will gradually get better, and one of the children will give the player the Seal Case in Generation IV. In the building next to the barn is the house where the family who owns the farm lives. It contains two farmers, a man and a woman. The man will sell MooMoo Milk to the player for 500 after MooMoo returns to health. The woman will reward the player with TM13 (Snore) in Generation II, and TM83 (Natural Gift) in Generation IV. In total there are five Miltank that appear on the farm, though there probably are many more, considering the amount of MooMoo Milk the farm must produce.
In the anime
Ash, Misty, and Brock visited the farm in A Dairy Tale Ending with Whitney. In the anime, MooMoo Farm is located outside of Goldenrod City and is overseen by Whitney's Uncle Milton. It is much like the MooMoo Farm in the games, as many Miltank lie around and graze. The farm was the location of Ash's rematch against Whitney where he defeated her Miltank.
There may also be a MooMoo Farm on Route 39 (as in the games) as referenced in Bulbasaur... the Ambassador!.
