Some deaths may occur as long as 3 weeks after a herd episode of overeating and acidosis. Less severe rumen lining damage may lead to liver abscesses and growth impairment. Laminitis, or founder, may follow acute acidosis, and evidence of subacute laminitis in the form of overgrown and deformed hooves may be present 30-60 days later. The only overt signs of subacute acidosis may be reduced gains and the presence of diarrhea in the form of flat gray stools. Because rumen lining damage may still occur in the absence of severe signs, these animals may develop chronic rumen damage and liver abscesses.
Weather conditions can cause fluctuations of intake of an otherwise acceptable ration.
Storm conditions can cause cattle to consume a greater amount of feed before and after the storm. Muddy conditions which can alter feed intake. A drop in barometric pressure can indicate oncoming storm conditions. Conditions that promote intake of the regular ration in a shorter amount of time can cause acidosis. Hot, humid weather will cause cattle to eat a greater proportion of their feed at night, rather than during the day.
