What would cause blood in bovine colostrum?

Blood in bovine colostrum can be caused by several factors, including trauma to the udder, mastitis, or other inflammatory conditions affecting the cow. It may also result from a ruptured blood vessel during the calving process or due to nutritional deficiencies. In some cases, infections or systemic diseases can lead to blood contamination in the colostrum. If observed, it’s important to consult a veterinarian for proper diagnosis and treatment.
