Prototheca bovis has been cultured in herds and is emerging as a threat to producers statewide. Prototheca has been linked to mastitis since 1952, however, within the last five years, the prevalence has significantly increased. Similar to Staph aureus and mycoplasma, Prototheca is hard to detect, has no known cure, and is contagious by intermittently shedding from cow to cow.
Heat stress occurs when an environment impacts the ability of a cow to get rid of body heat. Cows need to be raised in an environment where temperatures are within their thermoneutral zones to achieve their maximal genetic potential. Failures to establish adequate environmental temperatures can dramatically alter behavior, health, and productivity of cows.
