Canine osteoarthritis (OA) is a prevalent condition affecting dogs of all ages, with higher incidence observed in senior dogs and some large breeds. As OA is a slowly progressive degenerative joint disease, early management through nutritional strategies is of significant importance. Spray-dried animal plasma (SDAP) is a soluble, concentrated protein source known for its high nutritional value and immune-supporting properties. However, there are few studies about its effects on joint health in dogs. To investigate the impact of adding SDAP to food of senior dogs with OA, 24 dogs with OA were divided into two groups and fed either a basal diet or a diet supplemented with SDAP for a period of 42 days. The results indicated that dietary SDAP supplementation can alleviate the symptoms associated with canine arthritis by modulating inflammatory factors, antioxidants, and matrix metalloproteinases in canine serum and synovial fluid.
