Lameness in feedlot cattle.

Area of Science:

• Veterinary Medicine
• Animal Science
• Ruminant Health

Background:

• Lameness is a significant welfare and economic issue in feedlot cattle operations.
• Understanding the multifactorial causes of lameness is crucial for effective management.

Purpose of the Study:

• To provide a comprehensive overview of the primary causes of lameness in feedlot cattle.
• To highlight clinical signs, treatment options, and preventative measures for key lameness conditions.

Main Methods:

• Literature review of scientific articles and veterinary resources on feedlot cattle lameness.
• Synthesis of information on specific conditions including interdigital necrobacillosis, laminitis, and injuries.
• Discussion of Mycoplasma bovis-associated lameness and immune management of the foot.

Main Results:

• Identified interdigital necrobacillosis (foot rot), laminitis, and traumatic injuries as major causes of lameness.
• Highlighted Mycoplasma bovis as a significant pathogen contributing to feedlot lameness.
• Reviewed the importance of immune status and foot health management.

Conclusions:

• Effective management of feedlot lameness requires accurate diagnosis and targeted treatment.
• Prevention strategies should address environmental, infectious, and nutritional factors.
• Integrated approaches to animal health, including immune management, are essential for reducing lameness incidence.
