Why are no cows spawning?
Make sure you're not looking for cows in biomes they don't spawn in at all for example. But this shouldn't affect any tests that just look for passive animals regardless of species. And animals are less likely to spawn in: Dark Forests because the animals require a light level of 8 or higher to spawn.
You need to be in a plains or forest biome in order for them to spawn, a rain forest biome doesn't work. If you are looking at a desperate resource for milk you can always use spawn eggs to bring in cows and pigs.
Your server's view-distance setting is set too low.
If your server's view-distance setting is too small, it'll cause fewer mobs to spawn. We recommend increasing the view-distance setting in your server.
Their spawn rate varies per biome. Herds of two to three cows spawn in grass blocks at a light level of 9 or higher with at least two blocks of space above in Bedrock Edition, except in snowy taigas, snowy plains, meadows, mangrove swamps and wooded badlands.
Cows are common around Villages, Jungle Biomes, and Plains Biomes. When bred with Wheat, they produce calves.
Minecraft's brown Mooshroom cow is so rare that many veteran players don't even know. About its existence. This adorable creature is so rare that it has a 0.09765625% (1/1024) chance of spawning from breeding two Red Mooshroom Cows. They don't spawn without player interverence in any other way.
However, this is quite a difficult process, as each bred axolotl only has a 0.083% chance of being of blue coloration. Combining the relative rarity of lush cave biomes with an incredibly low percentage of getting a blue axolotl from breeding makes this color variant the rarest animal in all of Minecraft.
No, they do not. Animals are naturally generated entities in the game, and run on code. Once they die, their existence is erased from the face of the world, never to be seen again. Now the passive mob cap is not at the top, so there will be a higher chance that a passive mob will now spawn.
Mobs cannot spawn on buttons, levers, pressure plates, and all types of rails. Mobs other than water mobs are unable to spawn in water. Mobs other than striders are unable to spawn on lava.
Hold some of their favourite food out (wheat for sheep and cows; carrots for pigs; seeds for chickens). When they notice the food, they will look at you and follow you.
Do cows only spawn on grass?
Cows only spawn on grass, even if they're coming from a mob spawner. You need to surround the spawner with a nice 9x9 field to get maximum output.
Cows usually spawn in grassy biomes in small herds during world generation. Their spawn rates vary from one biome to another. For Bedrock Edition players cows spawn on grass blocks with a light level of 9 or higher, whereas for Java Edition players cows required only a light level of 7 at the lowest to spawn.

Mooblooms were a rare mob drop obtainable from cow tappables with a very low 0.6% chance of getting it, making it the rarest cow variant to obtain in Minecraft Earth. It was also obtainable by purchasing the "Roadside Inn" buildplate.
According to the Minecraft wiki: no, animals cannot spawn underground. newly generated chunks will contain mobs... They will always spawn on the highest available block in a column i.e. the one that can see the sky. For an animal to spawn on it, this block must be opaque and the two blocks above it must be transparent.
Soul Cows are slow, passive animal mobs that spawn in the Nether. They are the sources of Soul Hide, Soul Beef, & Blood.
No, you cannot turn a regular cow into a mooshroom, you can breed two adult mooshrooms wheat to produce a calf mooshroom. Mooshrooms only spawn in mooshroom island biomes.
A wheat crop has a total of eight stages (0-7) from the time it is planted until it can be harvested. If a crop is harvested before it is fully grown, it just drops one seed. Wheat needs light to grow; a seed is destroyed if planted without light.
Cows don't despawn, and that goes for all passive mobs.
In Minecraft, you can make an auto-cow farm by breeding a pair of cows and then guiding them to a farm. You can do this by feeding them wheat, and you can even breed them by requesting asexual cows from the game's developers. The cows can then be milked to get both hide and meat.
After players breed the cow, there is a significant cooldown period. This gap lasts five minutes, after which the animals will be ready to breed again.
How much XP do cows drop?
Cows can drop anywhere from one to three XP orbs when killed by a player or tamed wolf.
Cows kill more than 20 people in the United States each year, and the cause of death is most often blunt force trauma to the head or chest. Most victims are farm workers who are trampled, crushed or gored.
Remain calm and continue walking on quietly and quickly, trying to pass around them without making any startling movements. Cows will most likely leave you alone once they realize you are not a threat. If you detect an aggressive cow or a threatening group of cows, keep moving calmly and do not make direct eye contact.
Even though we can't ask cows how they're feeling, research has shown that cows have complex emotional lives. They don't just experience the two basic emotions—stress and contentment—they experience a full spectrum of complex emotions, including excitement, love, sadness, and fear.
Out of all different sheep, pink sheep are the rarest in Minecraft. Adult white sheep are the most common and have a 77.7442% chance of naturally spawning. On the other hand, pink sheep only have a 0.1558% chance of spawning in Minecraft.
