Preventing and Managing Mastitis in Goats

By Maci Guay

Homesteads and other dairy goat operations are increasing in popularity, as demand for fresh, unique milk products continues to rise. Goat milk is used to make various products such as butter, desserts, soaps, and lotions. However, as the dairy goat industry grows, so does the expectation for herd health surveillance, which is closely correlated with milk quality.

A common threat to milk quality is mastitis, a bacterial infection characterized by inflammation in the mammary gland. Because mastitis can escalate quickly if left untreated, early recognition, proper veterinary care, and diagnostic testing are crucial for herd health. By offering quick and precise diagnostic options, the Texas A&M Veterinary Medical Diagnostic Laboratory, TVMDL, helps goat producers and veterinarians stay ahead of mastitis.

Understanding Mastitis in Goats

Mastitis in goats resembles the condition observed in dairy cattle. It occurs when pathogens invade the mammary gland and cause inflammation. Common bacterial agents include Streptococcus, E. coli, and Mycoplasma.

Mastitis often begins when bacteria enter the udder through the teat canal. The risk of infection increases when animals are exposed to stress, overcrowding, sudden weather changes, or poor hygiene during milking. Goats infected with Caprine Arthritis Encephalitis, CAE, may also be more susceptible to bacterial infections.
