Male animal mob counterpart + herd of animals

Animal mobs having a male counterpart to protect same species from players/mobs. Imagine having herds of animals like cows roaming a grass plains, and having the added challenge to fight the bull/bulls protecting their herd. This could also be used with sheep and giving them rams to fight off wolves. Animal mobs have already been added to the game that attack the player (mountain goat, llama). Adding animal herds could make it more challenging for players as they would have to find or track the herd and fight off males to receive a bounty of meat and hide. The herds can be constantly moving together across the map still giving random probability of encounters. Herds moving across grass should have a foot step trail that eventually fades depending on how far the herd has moved. This feature could be used for hunting and tracking and a new use for horses and lassos to capture animals. This also gives a more realistic nature to animal mob entities and a new challenge for players.
