Animal value comparisons

I want to try to figure out which animals provide the most value when farmed so I can make determinations as to which animals I want to keep. There are a few axes of consideration:

  • Hunger rate — How much food does a single animal consume per day
  • Growth rate — How long until an animal is mature
  • Offspring — How many young are produced per pregnancy carried to term
  • Gestation — How long does a pregnancy take
  • Meat — How much meat is yielded when a single animal is slaughtered
  • Milk — How much milk does a single female animal provide averaged per day
  • Leather — How much leather is yielded when a single animal is slaughtered
  • Wool — How much wool does a single animal provide averaged per day

In addition to how much leather and wool is produced, different leather and wool are valuable for different reasons:

  • Armor
  • Heat Insulation
  • Cold Insulation
  • Sale Value

Given all of these values, I should be able to come up with a set of numbers that allows for general comparison of two animal breeds.
