Better artificial selection

All feedable animals have basic statistics that vary slightly: movement speed, jump strength (for equines), health points, attack damage (for domesticated wolves) loot intensity (for meat animals such as cows, sheep, pigs...). All these attributes can be modified from generation to generation. As the player feeds the animals, they can improve/deteriorate their statistics. In this way, you can have faster horses, stronger wolves and more profitable livestock. BONUS: telescope enchantment: "SCREENING", this enchantment allows you to see all these statistics of a targeted animal.
