The weight of fully grown pigs can vary depending on the breed, genetics, diet, and husbandry practices. Here are some approximate weight ranges for fully grown pigs of common breeds:
1. Yorkshire: Yorkshire pigs are large-sized pigs that can reach weights between 500 to 700 pounds (227 to 318 kilograms) or even more, depending on their intended purpose and management.
2. Duroc: Duroc pigs are medium to large-sized pigs. They typically reach weights ranging from 500 to 800 pounds (227 to 363 kilograms) or more, depending on their genetics and management.
3. Hampshire: Hampshire pigs are medium to large-sized pigs. They usually weigh between 500 to 800 pounds (227 to 363 kilograms) at maturity, but some individuals may exceed these weights.
4. Berkshire: Berkshire pigs are medium-sized pigs. They typically reach weights between 400 to 600 pounds (181 to 272 kilograms) or more, depending on their genetics and management.
5. Landrace: Landrace pigs are large-sized pigs known for their prolificacy. They can reach weights ranging from 500 to 700 pounds (227 to 318 kilograms) or more, depending on their genetics and management.
It's important to note that these weight ranges are approximate and can vary depending on factors such as breed variations, specific genetics within a breed, management practices, and the intended purpose of the pigs (e.g., breeding stock, market hogs, etc.). Additionally, individual pigs within a breed can show some variation in size and weight.
