Bone, or osseous tissue, is a dense connective tissue that forms the majority of the adult skeleton, providing essential support for the body. In areas where bones allow movement, such as the ribcage and joints, cartilage a semi-rigid form of connective tissue offers flexibility and creates smooth surfaces for ease of movement.
The skeletal system, composed of bones and cartilage, performs several critical functions for farm animals, including support, movement facilitation, organ protection, blood cell production, and the storage and release of minerals and fats.

Support, Movement, and Protection Functions of the Skeletal System
The most noticeable functions of the skeletal system include support, movement, and protection, which are easily observed. The bones and cartilage of the skeletal system act as the structural framework that supports the weight of farm animals, similar to how steel beams support a building. Without this system, farm animals would lack the rigidity required to maintain posture and structure.
Bones also aid in movement by serving as attachment points for muscles. In some cases, bones serve primarily as support, while in others, they transmit the forces generated by contracting muscles. From a mechanical perspective, bones act as levers, and joints serve as fulcrums.
For effective movement, muscles must span a joint and contract to cause bone movement. Additionally, bones provide protection for vital internal organs. For example, the ribs protect the lungs and heart, while the vertebral column safeguards the spinal cord.

Orthopedics in Farm Animals
Orthopedists specialize in diagnosing and treating issues related to the musculoskeletal system in animals. These professionals address bone and joint injuries, as well as conditions such as spinal curvature.
In animals, scoliosis, kyphosis, or other spinal deformities may result from injury, growth abnormalities, or aging-related issues. Orthopedists may treat these conditions through medication, physical therapy, or surgical intervention.
Some orthopedists also focus on sports medicine, which covers a range of injuries from simple sprains to complex joint issues. In working animals or livestock, injuries such as muscle strains or ligament tears can be managed through various treatments depending on the severity of the injury.
Mineral Storage, Energy Storage, and Hematopoiesis in Bone Tissue
On a metabolic level, bone tissue serves important functions in storing minerals like calcium and phosphorus. These minerals, crucial for muscle contractions and nerve impulse transmission, are stored in the bone matrix and released into the bloodstream as needed to maintain physiological balance.
In addition to mineral storage, bones act as a site for fat storage and blood cell production. The inner portion of most bones contains bone marrow, which comes in two types: yellow marrow and red marrow.
Yellow marrow contains adipose tissue, which stores triglycerides that can be used as an energy source. Red marrow is where hematopoiesis—the production of red and white blood cells, as well as platelets—occurs.
Major Functions of the Skeletal System in Farm Animals
The primary functions of bones in farm animals include providing structural support, facilitating movement, protecting internal organs, storing minerals and fat, and producing blood cells. Together with the muscular system, the skeletal system forms the musculoskeletal system, which is essential for the overall health and mobility of farm animals.
