Pig Skeletal System: Support, Growth, And Health

The axial skeleton in pigs, which includes the skull and vertebral column, provides support and protection for the central nervous system and vital organs. The appendicular skeleton, consisting of the bones of the limbs, facilitates movement and weight-bearing in pigs. Bone remodeling is a continuous process in the pig skeletal system and helps maintain bone strength and mineral homeostasis. Understanding the developmental stages of the pig skeletal system is crucial for assessing growth and identifying potential skeletal abnormalities.

Ever wondered what keeps a pig, well, a pig? It’s not just the mud baths and snorts! The unsung hero is the skeletal system, the very framework that dictates so much about a pig’s life. From the way they strut around the farmyard to how efficiently they convert feed into, well, bacon, their bones are the foundation. Think of it as the scaffolding of a building, but instead of bricks and mortar, it’s all about bones and cartilage.

Why should you, whether you’re a farmer, vet, or just a curious soul, care about a pig’s skeleton? Because understanding it is key to everything! For farmers, it’s about optimizing growth and ensuring animal welfare. Vets need to know the ins and outs to diagnose and treat bone-related issues effectively. And for researchers, the pig skeletal system provides valuable insights into bone biology that can even translate to human health.

Let’s talk functions, shall we? The pig skeletal system is like a Swiss Army knife. It’s all about support, holding the body upright like a champ. Then, there’s protection, with ribs acting as bodyguards for vital organs. Movement? Of course! Bones and muscles team up for locomotion and general pig shenanigans. And that’s not all! Bones are a mineral storage unit, a blood cell factory, and even play a role in hormone regulation.

To put it into perspective, imagine this: A seemingly healthy pig suddenly starts limping. Is it just a minor stumble, or could it be a developing skeletal issue? Believe it or not, approximately 20% of pigs experience lameness during their lifetime, which significantly impacts their growth and overall well-being. Such alarming statistic underscores the importance of understanding and safeguarding the skeletal health of these animals. It’s these sorts of hidden challenges that highlight how crucial it is to delve into the world of pig bones. Get ready, because we’re about to dive deep into the oink-redible world of the pig skeletal system!

Building Blocks: Bone Tissue and Microscopic Structure

Alright, let’s zoom in and get tiny! We’re diving deep into the microscopic world of pig bones – the real nitty-gritty stuff that makes these amazing structures so darn strong and versatile. Think of it like this: if the skeletal system is the blueprint for the whole pig, then bone tissue is the building material, and we’re about to see what that material is made of.

Two Flavors of Bone: Compact and Spongy

First up, we have two main types of bone tissue: compact and spongy. Compact bone, also known as cortical bone, is the tough outer layer – imagine the hard shell of an egg. It’s dense and provides most of the bone’s strength, keeping everything held together nice and tight. Then there’s spongy bone, or cancellous bone, on the inside. Don’t let the name fool you; it’s still strong, but it’s porous, kind of like a sponge (duh!). This porous structure helps house bone marrow and acts as a shock absorber, protecting the bone from impact. So compact bone is the body-guard, and spongy bone is the springy interior.

The Bone Crew: Osteocytes, Osteoblasts, and Osteoclasts

Now, let’s meet the bone cells – the tiny workers that keep everything in tip-top shape. Think of them as a construction crew, demolition crew, and maintenance team all rolled into one. Osteocytes are the mature bone cells; they’re like the caretakers of bone tissue. These guys maintain the bone matrix and monitor the general health of the bone. Osteoblasts are the bone-forming cells, which are the construction crew responsible for bone deposition. These cells build new bone and help bones grow. Osteoclasts are the bone-resorbing cells; they’re the demolition crew involved in bone resorption. They break down old or damaged bone, making way for new bone growth. It’s a continuous cycle of building and breaking down, constantly reshaping and repairing bones.

The Bone Matrix: Collagen and Hydroxyapatite

The bone matrix is the material that surrounds the bone cells, kind of like the concrete in reinforced concrete. It’s composed of two main ingredients: collagen and hydroxyapatite. Collagen is a protein that provides flexibility – it’s like the steel rebar in concrete, giving the bone its tensile strength. Hydroxyapatite is a mineral crystal that provides hardness – it’s like the cement in concrete, making the bone resistant to compression. Together, collagen and hydroxyapatite make bone strong, resilient, and capable of storing minerals.

Bone Membranes: Periosteum and Endosteum

Bones also have membranes that help protect and nourish them. The periosteum is the outer membrane that covers the bone. It’s like the skin of the bone, providing protection and a pathway for blood vessels and nerves. The periosteum also contains cells that are important for bone growth and repair. The endosteum is the inner membrane that lines the bone cavities. It’s a thin layer of cells that helps regulate bone remodeling.

Bone Marrow: Red and Yellow

Finally, let’s talk about bone marrow, the soft tissue found inside bones. There are two types of bone marrow: red marrow and yellow marrow. Red marrow is responsible for hematopoiesis, which is the formation of blood cells. It’s like the factory for red blood cells, white blood cells, and platelets. Yellow marrow is mainly responsible for fat storage. It’s like a reserve energy source that can be used when needed.

And that, my friends, is a peek into the microscopic world of pig bones! Understanding these basic building blocks is essential for understanding how bones function, how they grow, and how to keep them healthy.

Cartilage: The Unsung Hero of Smooth Moves

Imagine your joints without cartilage – it would be like metal grinding on metal, a surefire recipe for discomfort! Cartilage is a specialized connective tissue that plays a crucial role in the skeletal system, primarily by facilitating smooth movement and providing support. Let’s break down the different types:

• Hyaline Cartilage (Articular Cartilage): Think of this as the Teflon on your favorite frying pan. It’s the slick, smooth covering on the surfaces of your joints, allowing bones to glide effortlessly against each other. This type is predominantly found at the ends of bones in joints, ensuring friction-free movement.
• Fibrocartilage: These cartilage are the shock absorbers in your car. You can find them located in intervertebral discs. It’s tough and resilient, providing cushioning and support in areas that experience a lot of stress. The intervertebral discs in the spine and the menisci in the knee are prime examples.
• Elastic Cartilage: Think of this cartilage as a flexible yet supportive framework. Unlike hyaline or fibrocartilage, elastic cartilage is highly flexible due to the presence of elastic fibers within its matrix. This type is commonly found in structures like the external ear, providing support while allowing them to maintain their shape and flexibility.

Joints: Where the Magic Happens

Joints are the meeting points between two or more bones, and they are essential for movement. They come in various forms, each designed for a specific range of motion:

• Synovial Joints: These are the freely movable joints, the rockstars of the skeletal system. They include hinge joints like the knee and elbow, allowing movement in one direction (like opening and closing a door), and ball-and-socket joints like the hip and shoulder, offering a wide range of motion in all directions.
• Cartilaginous Joints: These joints are connected by cartilage, allowing for some movement, but not as much as synovial joints. An example is the joints between vertebrae in the spine.
• Fibrous Joints: These are the immovable joints, the strongholds of the skeletal system. They’re connected by fibrous tissue, providing stability and protection. The sutures in the skull are a classic example, where the bones are tightly interlocked and don’t allow movement.

Ligaments and Tendons: The Unsung Heroes of Joint Stability and Movement

Joints wouldn’t function effectively without their supporting structures. Think of ligaments as strong ropes connecting bone to bone, providing stability and preventing excessive movement, thus avoiding dislocations. Tendons, on the other hand, are like cables that transmit the force from the engine (muscles) to the wheels (bones), enabling movement. They connect muscles to bones, allowing us to flex, extend, and rotate our limbs.

The Six Pillars: Detailed Functions of the Pig Skeletal System

Alright, let’s dive into the meat (pun intended!) of why a pig’s skeleton is so darn important. It’s not just a frame to hang bacon on; it’s a multi-tasking marvel that keeps our porky pals strutting, protected, and generally thriving. Think of it as the unsung hero of the pig world!

Support: The Pig’s Inner Scaffolding

First up, support. Just like a building needs a strong frame, a pig needs a skeleton to hold everything together. It’s what gives them their shape, keeps them upright, and allows them to strike a pose (even if that pose is usually face-down in a mud puddle). Without it, well, they’d be a puddle of something else entirely!

Protection: A Built-In Bodyguard

Next, we’ve got protection. Those bones aren’t just for show; they’re like a built-in bodyguard for all the important stuff inside. The rib cage, for example, is like a fortress protecting the heart and lungs from any accidental oinks and shoves. Imagine a pig playing football without that rib cage…ouch!

Movement: Pig-Powered Locomotion

Then there’s movement. Now, pigs might not be known for their graceful ballet moves, but they do need to get around, and their skeleton is key to this. The bones act as levers, with muscles pulling on them via tendons to create motion. And let’s not forget the ligaments, those trusty connectors that keep everything stable and prevent any unwanted wobbly bits.

Mineral Storage: A Calcium and Phosphorus Piggy Bank

Mineral storage is another crucial function. Bones are like a piggy bank for essential minerals like calcium and phosphorus. When the body needs a top-up, it can withdraw from this bone bank, keeping everything balanced and harmonious. It’s all about maintaining that sweet, sweet homeostasis.

Blood Cell Formation (Hematopoiesis): The Bone Marrow Factory

Time for blood cell formation (hematopoiesis). Deep inside the bones, in the bone marrow, red and white blood cells are produced. Red blood cells are vital for oxygen transport, and white blood cells are essential for the immune response.

Endocrine Regulation: The Bone-Hormone Connection

Lastly, endocrine regulation. Who knew bones could talk to other organs? Well, they do! Bones release hormones that can influence other organs, like the kidneys. This shows the pig skeletal system is a team player, contributing to the bigger picture of pig health.

From Piglet to Adult: Bone Development and Growth Processes

Ever wondered how a tiny, wobbly piglet transforms into a robust hog? A big part of that magic lies in the amazing process of bone development! It’s not just about getting bigger; it’s about building a strong foundation for a lifetime of rooting, wallowing, and generally living the pig life. Let’s dive into the fascinating world of how those bones come to be.

Ossification: From Blueprint to Bone

Think of ossification as the construction phase of bone building. There are two main ways this happens:

• Endochondral Ossification: This is the star player when it comes to long bones like the legs and ribs. Imagine cartilage as the initial blueprint. Over time, this cartilage is gradually replaced by bone tissue. It’s like replacing a temporary scaffolding with solid brick and mortar. It’s the main process for long bone development.

• Intramembranous Ossification: This is the direct approach and it happens primarily with skull bones. Instead of cartilage first, bone forms directly from mesenchymal tissue – a type of embryonic connective tissue. Think of it as skipping the blueprint and building straight from the ground up!

Growth Plates (Epiphyseal Plates): The Fountain of Youth (for Bones!)

These are special zones of cartilage found at the ends of long bones in growing pigs. Consider growth plates as the engine of bone elongation. New cartilage cells are constantly produced here, pushing the older cells towards the middle of the bone where they get ossified. It’s like a conveyor belt of growth! But alas, all good things come to an end. Eventually, these growth plates “close” as the pig matures, marking the cessation of bone lengthening.

Bone Remodeling: The Ultimate Makeover

Bone isn’t static. It’s constantly being remodeled, which is a continuous process of Bone Resorption (breakdown) and Bone Deposition (formation).

This dynamic process ensures that bone remains strong, repairs damage from everyday wear and tear, and adapts to the stresses placed upon it. It’s like a construction crew that’s always on call, fixing potholes and reinforcing weak spots!

The Nutritional Foundation: Building Bones from the Inside Out

Just like any construction project, bone development needs the right materials. Calcium, phosphorus, and vitamin D are the superstar nutrients when it comes to building strong bones. These nutrients are the building blocks that ensure bone grows at the proper rate. Without them, bones can become weak and prone to fractures and this is why it’s so important to make sure your pigs are getting enough of these nutrients in their diet, especially during their rapid growth phases.

The Central Axis: Exploring the Axial Skeleton of Pigs

Think of the axial skeleton as the pig’s central support system, the sturdy core around which everything else is organized. It’s like the main trunk of a tree, providing stability and protection. This crucial part is comprised of the skull, vertebral column, and rib cage. Let’s break it down bone by bone!

Decoding the Pig Skull: More Than Just a Pretty Face

The skull, that hard helmet encasing the pig’s precious brain, is more complex than it seems. It’s divided into two main parts:

Cranium

This is the braincase, the fortress protecting that all-important control center. It’s made up of several bones, including the:

• Frontal Bone: Forming the forehead.
• Parietal Bones: Making up the sides and roof of the cranium.
• Occipital Bone: Forming the back of the skull.
• Temporal Bones: Housing the ears.
• Sphenoid Bone: A complex, bat-shaped bone at the base of the skull.
• Ethmoid Bone: Located between the eyes and nasal cavity.

Facial Bones

These bones give the pig its distinctive snout and facial features. They include the:

• Nasal Bones: Forming the bridge of the nose.
• Maxilla: The upper jawbone, holding the upper teeth.
• Mandible: The lower jawbone, the only movable bone in the skull.
• Zygomatic Bones: Forming the cheekbones.
• Lacrimal Bones: Small bones in the eye sockets.
• Palatine Bones: Forming part of the hard palate (roof of the mouth).
• Vomer: Forming part of the nasal septum (dividing the nasal cavity).
• Incisive Bones: Holding the incisor teeth in the upper jaw.

Don’t forget the Hyoid Bone, a horseshoe-shaped bone in the neck that supports the tongue and helps with swallowing. It’s like a little hammock for the tongue!

The Vertebral Column: A Flexible Backbone

The vertebral column, or spine, is a series of connected bones (vertebrae) that provide support and flexibility. It’s like a strong, flexible chain, allowing the pig to move and bend. It’s divided into regions:

Cervical Vertebrae

These are the neck vertebrae, allowing the pig to turn its head. The first two are special:

• Atlas: The first cervical vertebra, allowing the “yes” movement.
• Axis: The second cervical vertebra, allowing the “no” movement.
• C3-C7: The remaining cervical vertebrae.

Thoracic Vertebrae

These vertebrae have ribs attached to them and form the chest region. They provide a strong anchor point for the rib cage.

Lumbar Vertebrae

Located in the lower back, these vertebrae support the abdomen and bear a lot of weight.

Sacral Vertebrae

These vertebrae are fused together to form the Sacrum, which connects the spine to the pelvis.

Caudal Vertebrae

These are the tail bones, also known as the Coccyx. The number of these bones can vary between pig breeds, which explains why some have longer tails than others.

Between each vertebra are Intervertebral Discs, acting as shock absorbers and allowing for flexibility.

The Rib Cage: Protecting Vital Organs

The rib cage is a bony shield protecting the heart, lungs, and other vital organs. It’s made up of the:

Ribs

These bones form the sides of the chest. They are classified as:

• True Ribs: Connected directly to the sternum.
• False Ribs: Connected to the sternum indirectly through cartilage.
• Floating Ribs: Not connected to the sternum at all.

Sternum

This is the breastbone, located in the center of the chest. It consists of three parts:

• Manubrium: The upper part of the sternum.
• Body: The main part of the sternum.
• Xiphoid Process: The small, cartilaginous tip of the sternum.

Imagine a diagram showcasing the axial skeleton of a pig, carefully labeled with all these bony landmarks. It’s like a map to the pig’s inner structure, guiding you through the complex architecture of its central support system.

Limbs in Action: Understanding the Appendicular Skeleton

Alright, let’s get down to the nitty-gritty of how pigs get around – the appendicular skeleton! Think of this as the chassis and wheels of the pig body. These bones are the ones that allow them to strut their stuff, root around, and generally do all the piggy things we know and love. This section will break down the skeletal structure of those legs and feet, ensuring you have a solid understanding of the engine that drives these animals forward.

Components: Bones of the Forelimb (Thoracic Limb) and Hindlimb (Pelvic Limb)

The appendicular skeleton is conveniently divided into two main sets of limbs: the forelimbs, or thoracic limbs, and the hindlimbs, known as pelvic limbs. The names might sound fancy, but the concept is simple. The forelimbs are the pig’s front legs, and the hindlimbs are the back legs. Each limb is a complex assembly of bones working together, kind of like a well-coordinated dance team.

Forelimb (Thoracic Limb)

• Scapula: This is the shoulder blade. It is the connection point between the forelimb and the rest of the skeleton. You can think of it as the scaffolding that keeps the whole arm from falling off!

• Humerus: The upper arm bone. Imagine this as the long bone that extends from the shoulder to the elbow. It’s like the prime mover for many forelimb actions.

• Radius: On the lateral side (outer side), this is one of the two forearm bones.

• Ulna: On the medial side (inner side) of the forearm, working together with the radius, the ulna helps facilitate movement at the elbow joint.

• Carpals: These are the wrist bones. In pigs, these are a series of small bones that provide flexibility and support to the wrist.

• Metacarpals: Hand bones extend from the wrist to the base of the digits.

• Phalanges: Ah, the finger bones! Pigs don’t exactly give high-fives, but their phalanges are essential for digging, walking, and general ground exploration. The number of phalanges varies between digits, adding to the uniqueness of each hoof.

Hindlimb (Pelvic Limb)

• Pelvis: The hip bone. This is actually a fusion of three bones – the Ilium, Ischium, and Pubis. Think of it as the strong foundation connecting the hindlimb to the axial skeleton. It’s like the architectural base upon which the entire leg is built.

• Femur: The thigh bone. As the largest bone in the body, the femur bears a lot of weight and is crucial for movement.

• Patella: The kneecap. It sits in front of the knee joint, providing protection and leverage. Without the patella, a pig’s jump would be as effective as a screen door on a submarine.

• Tibia: The shin bone. It’s one of the two bones in the lower leg, and it’s on the medial side (the inside of the leg).

• Fibula: The other bone in the lower leg, located on the lateral side (the outside of the leg). It is thinner compared to the tibia.

• Tarsals: These are the ankle bones. Like the carpals in the wrist, tarsals allow for a range of motion and shock absorption.

• Metatarsals: Foot bones extend from the ankle to the toes.

• Phalanges: Just like the forelimb, the hindlimb ends with phalanges, or toe bones. Essential for balance and propulsion!

Supporting Cast: Muscles, Nerves, and Blood Vessels

Let’s not forget the supporting cast! Bones can’t do it alone; they need the help of muscles, nerves, and blood vessels to function correctly.

• Muscles: These are the engines that drive the skeletal system. Attached to the bones, muscles contract to create movement.
• Nerves: Nerves are the messengers that transmit signals between the brain and the muscles, telling them when and how to move.
• Blood Vessels: Delivering essential nutrients and oxygen to the bones and removing waste products.

Bone Features: Foramen and Processes

Even the bones themselves have unique features that contribute to their function:

• Foramen: Think of these as tiny tunnels in the bone. Blood vessels and nerves pass through these holes to keep the bone alive and functioning.
• Processes: These are bony projections where muscles attach. The size and shape of these processes can tell you a lot about the muscle’s strength and function.

Visual Aid: Labeled Diagram of the Appendicular Skeleton

To tie it all together, a labeled diagram is super helpful. Seeing all these bones in their proper places can make a world of difference in understanding their functions. This visual guide will help you identify each bone and understand its role in the pig’s overall anatomy.

And there you have it! A tour of the pig’s appendicular skeleton. These bones work together to help pigs do what they do best: move, explore, and, of course, look adorable while doing it. Next time you see a pig, take a moment to appreciate the complex machinery working beneath the surface!

When Bones Go Wrong: Common Skeletal Conditions in Pigs

Let’s face it, nobody wants to see a pig hobbling around. It’s bad for the pig, bad for your bottom line, and frankly, just a bit depressing. So, let’s dive into some common skeletal issues in our porky pals, so you can spot them early and take action. It’s not all doom and gloom, but being informed is the first step to keeping your pigs happy and healthy!

Leg Weakness and Lameness: A Pain in the Hoof!

Imagine trying to run a marathon with shoes two sizes too small. Not fun, right? That’s kind of what leg weakness and lameness feel like for a pig. This is super common in pig farming, and there are loads of reasons why it might be happening. Think about it:

Causes:

• Rapid Growth: These guys grow FAST. Sometimes their bones just can’t keep up with the speed of their ever growing body!
• Poor Nutrition: Bones need the right building blocks, like calcium and phosphorus. If their diet is lacking, their legs can suffer.
• Genetic Factors: Some pigs are just predisposed to weaker bones. It’s like drawing the short straw in the gene pool.
• Environmental Conditions: Slippery floors are a HUGE culprit. Imagine trying to do the Macarena on ice! Falls and strains are inevitable.

Symptoms:

• Difficulty Walking: This one’s pretty obvious.
• Reluctance to Move: If they’re avoiding walks, something is definitely up.
• Abnormal Gait: A limp, shuffle, or any unusual way of walking is a big red flag.

Prevention:

• Balanced Diet: The foundation for strong bones! Talk to a nutritionist to get it right.
• Proper Flooring: No more ice rinks! Provide good traction to reduce slips and falls.
• Genetic Selection: Choose breeding stock with strong legs and sound conformation. It’s like building a house on a solid foundation.

Fractures: Ouch!

No one wants to think about a broken bone, but accidents happen. Whether it’s a fall, a fight, or just plain bad luck, fractures can really set a pig back.

Causes:

• Trauma: Getting kicked, stepped on, or slammed against a wall.
• Falls: See “slippery floors” above!
• Aggressive Behavior: Pigs will be pigs, and sometimes those pigs will fight!

Symptoms:

• Swelling: A sure sign of trouble.
• Pain: Obvious if the pig is vocalizing or unwilling to put weight on the limb.
• Inability to Bear Weight: If they can’t stand on it, it’s serious.

Treatment:

• Veterinary Care: A must. Don’t try to be a DIY bone setter!
• Immobilization: Keeping the bone still to promote healing.
• Pain Management: Because, ouch!

The Bottom Line: Economic Impact

Skeletal problems aren’t just bad for the pigs; they hit your wallet too!

• Reduced Growth Rate: A lame pig isn’t eating as much or converting feed efficiently.
• Increased Culling Rates: Severely affected pigs may need to be culled, leading to financial losses.

By taking preventative measures and keeping a close eye on your pigs, you can minimize these issues and keep your operation running smoothly. Think of it as an investment in your pig’s health and your own peace of mind!

Building Strong Bones: It’s Not Just Luck – Nutrition and Genetics Play a HUGE Role!

Ever wonder how some pigs seem to breeze through life with nary a limp, while others are plagued with leg problems? Sure, a bit of luck is involved, but the real secret sauce lies in two key ingredients: nutrition and genetics. Think of it like this: you can’t build a skyscraper with flimsy materials, and you can’t expect a pig to have a rock-solid skeleton if it’s not getting the right building blocks or if it’s got blueprints for weakness. Let’s dig in, shall we?

The Perils of a Piggy Diet Deficient in Key Nutrients

Imagine trying to build a house with only half the bricks you need. That’s what it’s like for a pig trying to develop strong bones without the right nutrients. We’re talking about the big three here: Calcium, Phosphorus, and Vitamin D. These aren’t just fancy names – they’re essential for bone density and overall skeletal health.

• Calcium and Phosphorus are the main minerals that make up bone. Without enough, the bones become weak and brittle, increasing the risk of fractures. It’s like building a wall with crumbly bricks – it just won’t stand up to pressure.
• Vitamin D helps the body absorb calcium and phosphorus. Think of it as the foreman on the construction site, making sure everything is in the right place at the right time. Without enough vitamin D, the pig could be eating plenty of calcium and phosphorus, but it won’t be able to utilize them properly.

The consequences of these deficiencies can be pretty grim: weak bones, a higher risk of fractures, and slower growth rates. No farmer wants that! The solution? Balanced feed formulations are key. Work with a nutritionist to ensure your pigs are getting exactly what they need at each stage of life. And don’t be afraid to consider supplementation if necessary, especially for rapidly growing piglets or sows during lactation. Remember, a well-fed pig is a happy (and sturdy) pig!

It’s in the Genes: Why Selecting the Right Breeding Stock Matters

Now, let’s talk about the other side of the coin: genetics. Just like humans, pigs inherit traits from their parents, and that includes predispositions to certain skeletal issues. One common culprit is osteochondrosis, a fancy word for a condition that affects cartilage and bone development. It’s like having a blueprint for a building with a weak foundation – even with the best materials, the structure is still at risk.

That’s why selecting breeding stock with strong bone structure and good conformation is absolutely crucial. Take a good look at those potential parents! Are their legs straight and sturdy? Do they move with ease and confidence? These are all clues to their underlying skeletal health. And hey, don’t just rely on appearances! Genetic testing is becoming increasingly available and can help identify carriers of certain genes associated with skeletal problems. It’s like getting a detailed structural analysis of the building materials before you even start construction.

By combining smart nutrition with careful genetic selection, you can stack the odds in your favor and build a herd of pigs with strong, healthy skeletons. It’s an investment that pays off in the long run with improved welfare, reduced lameness, and increased productivity. After all, a solid foundation is the key to success, whether you’re building a skyscraper or raising pigs!

So, there you have it! A peek under the hood of our porcine pals. Who knew there was so much going on beneath that curly tail and adorable snout? Next time you see a pig, remember the amazing framework that helps them snuffle, root, and, well, just be pigs!
