The amount of wool produced by a sheep in a year can vary depending on factors such as the breed of sheep, its health, nutrition, and environmental conditions. Additionally, the shearing schedule can also impact the quantity of wool.
On average, a mature sheep can produce anywhere from 2 to 30 pounds (1 to 14 kilograms) of wool per year. However, certain specialized breeds that have been selectively bred for their wool production can yield higher amounts. For example, Merino sheep, known for their fine wool, can produce 10 to 30 pounds (4.5 to 14 kilograms) of wool annually.
It's worth noting that the weight of the raw wool will differ from the weight of the processed or usable wool due to factors like lanolin (grease) and dirt being removed during the cleaning and processing stages.
