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. In Pokémon Gold, Silver, and Crystal, the Farmer inside the farm house will sell it to the player for 500, but only one can be bought at a time. If the player already has a Moomoo Milk in their Bag, the Farmer will not sell anything. In HeartGold and SoulSilver, the player is able to buy one Moomoo Milk for 500, or a dozen for 6000, regardless of whether the player is already holding one or not.
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 seven ordinary Berries in Generation II or seven Oran Berries in Generation IV it will help her 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.

The Miltank dairy in the anime
Ash, Misty, and Brock visited a Miltank dairy in A Dairy Tale Ending with Whitney. In the anime, it is located outside of Goldenrod City and is overseen by Whitney's Uncle Milton. Much like the Moomoo Farm in the games, many Miltank lie around and graze. The farm was the location of Ash's rematch against Whitney, where he defeated her Miltank, earning him the Plain Badge.
A location named MooMoo Ranch near Ecruteak City was mentioned in Bulbasaur... the Ambassador!.

Moomoo Farm in Pokémon Adventures
In the Pokémon Adventures manga
Moomoo Farm first appeared in Miltank Melee, where the farm couple was trying to cure a sick Miltank. Eusine and his Jumpluff crashed through the roof of the barn, and he proceeded to cure the sick Miltank, though he tricked the farm couple into thinking he did it with magic. Soon after Eusine left the farm, Crystal confronted him about this and revealed that all he did was cleverly slip the Miltank a Berry.
In The Last Battle XIII, the couple was seen sending multiple Miltank to help in the fight with Ho-Oh and Lugia in Ilex Forest.
The farm made a brief cameo in All About Arceus III, where Silver and his Weavile were seen discovering a Plate at the farm meadow.
In the Pokémon Gold & Silver: The Golden Boys manga
Moomoo Farm was first mentioned in A Promise Given to Miltank, when Morty said that all the Miltank on the farm were sick. In Let's Fight! The Mini Pokémon Tournament, Gold entered a Pokémon tournament at the farm.
