Once pigs reach market weight, they are processed for pork products, contributing to the supply chain that feeds millions of people.
12. Pigs communicate through grunts.
Pigs have a wide range of vocalizations, with more than 20 different types of grunts, squeals, and snorts that they use to communicate. Each sound can signal something different, from hunger to contentment to warning. Farmers and animal behaviorists can often tell a pig’s mood based on its vocalizations, allowing them to better care for the animals.
13. Pork exports are a major part of the U.S. agricultural economy.
The U.S. exports over two million metric tons of pork each year, with major markets including Mexico, Japan, and China. These exports contribute billions of dollars to the U.S. economy annually, supporting jobs and growth in rural areas. International demand for U.S. pork helps maintain the industry’s profitability and sustainability.
14. Pigs are social animals.
Pigs naturally form close-knit groups called sounders, where they interact and form bonds with other pigs. In their social groups, they engage in behaviors like grooming and playing, which helps reduce stress. Their social nature makes them responsive to human interaction as well, which is why they often thrive in environments where farmers take the time to engage with them.
15. Modern pig farming practices focus on sustainability.
The U.S. pork industry has made great strides in adopting sustainable farming practices that minimize environmental impact. These include better waste management systems, efficient feed conversion, and the use of renewable energy on farms. By reducing the environmental footprint, the swine industry contributes to a more sustainable food system.
16. Pigs are omnivores.
Pigs eat a wide variety of foods, from grains and vegetables to fruits and even small animals (in the wild). On farms, their diets are carefully controlled to ensure they get the right balance of nutrients for healthy growth. The fact that pigs are omnivores makes them versatile animals, able to adapt to different feeding systems based on availability of resources.
17. The average litter size for pigs is 10 to 12 piglets.
Sows usually give birth to 10 to 12 piglets per litter, though some litters can be even larger. Farmers closely monitor pregnant sows and assist with the birthing process to ensure the health of both the sow and her piglets. Managing large litters is essential to maintaining a productive pig farming operation.
18. Pigs have excellent memories.
Pigs have the ability to remember locations, routes, and people for long periods of time. They can recall where food sources are located and recognize familiar individuals, both human and pig. This strong memory makes pigs highly adaptable and capable of learning from their experiences.
19. Pork is a rich source of protein and essential vitamins.
Pork is an excellent source of high-quality protein, as well as important vitamins like B12, B6, and minerals like zinc and iron.
