Layer 4: Stocks and flows
4.11. Stocks: Livestock
How much livestock is present within the territory? Think of cattle, sheep, goats, pigs, chickens, and any other type of livestock. These numbers are possibly available from the agricultural authority, or from industry associations. For some animals these numbers will constantly fluctuate, as they are killed at a high rate. Obtaining information of the average lifespan is therefore also beneficial.
