A few suggestions for features I'd like to see in the mod:

• Another pig breed, the Husum Red Pied, AKA the Danish Protest Pig. This has become one of my favorite pig breeds due to its history, which greatly amuses me in its subversiveness. Bonus points because it could raise awareness about an heirloom breed that currently has a very small population.
• Another cow breed, Jersey Cow. Milk breed with a unique coloration, whereas most of the current breeds are some flavor of spotted.
• Config options to enable obtaining color variants of animals by breeding, probably on a species-by-species basis. This could be implemented either as a small random mutation chance regardless of parent color or by breeding tree similar to the Chickens mod or Forestry bees (minus the resource drops or advanced trait aspects, obviously), if still as a random chance. This is probably primarily applicable to species where color variants are truly color variants, not distinct breeds, so draft horses and peafowl (along with ferrets/hedgehogs if breeding for them is implemented at some future point).
