Intermittent Feeding Of Tylan Reduces Use Of In-Feed Antibiotics While Still Controlling Incidence Of Liver Abscesses In Finishing Steers, H. C. Muller, R. G. Amachawadi, H. M. Scott, J. S. Drouillard
Intermittent Feeding Of Tylan Reduces Use Of In-Feed Antibiotics While Still Controlling Incidence Of Liver Abscesses In Finishing Steers, H. C. Muller, R. G. Amachawadi, H. M. Scott, J. S. Drouillard
Kansas Agricultural Experiment Station Research Reports
Liver abscesses are a cause of concern for many feedlots across the country as they lead to a decrease in feedlot performance of finishing cattle as well as a decrease in the final carcass value. Loss in carcass value is due to not only the abscessed liver being condemned, but also due to trim loss associated with the condemned liver. The macrolide drug tylosin phosphate is the drug of choice for metaphylactic treatment of liver abscesses in feedlot cattle. The Food and Drug Administration approved the drug for over-the-counter use, however, from January 2017 all medically important (used in human …
Supplemental Zinc Sulfate Interacts With Optaflexx In Feedlot Heifers, C. L. Van Bibber-Krueger, R. G. Amachawadi, H. M. Scott, J. M. Gonzalez, J. S. Drouillard
Supplemental Zinc Sulfate Interacts With Optaflexx In Feedlot Heifers, C. L. Van Bibber-Krueger, R. G. Amachawadi, H. M. Scott, J. M. Gonzalez, J. S. Drouillard

Optaflexx is a beta-adrenergic agonist, and is fed to cattle during the final 28 to 42 days on feed to improve growth rate and feed efficiency. Beta-adrenergic agonists are repartitioning agents that stimulate muscle deposition at the expense of fat deposition. Zinc is a trace mineral element that functions as an important component of many enzyme systems, including those associated with nucleic acid synthesis and metabolism of proteins and carbohydrates, thus making it an essential nutrient for growth. The purpose of this study was to evaluate growth, carcass characteristics, and plasma urea nitrogen concentrations in finishing heifers supplemented with Optaflexx …
Antioxidant Feeding Does Not Impact Incidence Or Severity Of Liver Abscesses, H. C. Muller, C. L. Van Bibber-Krueger, J. S. Drouillard

Liver abscesses are a large source of economic loss in feedlot cattle. Not only do liver abscesses lead to a decrease in feedlot performance, but these livers are condemned in the abattoir and can also lead to a further decrease in carcass value due to trim loss. Tylosin phosphate is a metaphylactic macrolide drug that effectively decreases the occurrence of liver abscesses. The drug is approved by the Food and Drug Administration for over-the-counter use. However, in January 2017 the FDA will require a veterinary feed directive for medically important antibiotics (antibiotics that are used in human health) used in …
