Interpretive Summary: Stocker steer operations are regaining popularity throughout the Southeast. Increased production efficiency of the stocker enterprise is necessary to increase profitability. Supplementation and steroid implantation of steers increased average daily gain and altered lactate dehydrogenase activity. Altered lactate dehydrogenase activity may be one mechanism by which supplementation and steroid implantation improved steer performance. This information is of interest to beef producers, extension personnel, and agricultural professionals who advise beef producers on beef management practices.
Technical Abstract: The transition period from non-lactating to lactating in dairy cattle is too often unsuccessful. Body temperatures were monitored and metabolic disorders identified in Holstein cows. Cows with fever were orally administered a regiment of four aspirin boluses and one probiotic supplement. This non-antibiotic treatment prevented the recurrence of fever during the first seven days after calving in older cows but not first-calf cows. Fever and metabolic disorders during the first seven days after calving decreased milk production and reduced pregnancy rates in Holstein cows. This information is of interest to extension personnel, dairy consultants, and dairy producers.
