FDA Approves Combination Feeding Of Pennchlor, Rumensin To Beef Cattle

Oct 06, 2022

The Food and Drug Administration on July 28 approved feeding Pennchlor, which contains chlortetracycline, and Rumensin, which contains monensin, in combination under a veterinary feed directive to beef calves 2 months of age and older and to growing beef steers and heifers fed in confinement for slaughter. The drug sponsor is Pharmgate Inc.

“We are very excited about the opportunity and flexibility this new combination claim provides feedlot operators and cattle producers,” said Ed Seed, vice president of global sales and marketing at Pharmgate Animal Health. “We’ve been working over the past month to make the updated labeling and Veterinary Feed Directive forms available to the cattle feed and veterinary industry and are now working collaboratively to roll this out more broadly.”

Pennchlor and Rumensin are Type A medicated articles to be used in the manufacture of Type B and Type C medicated feeds. See the FDA page regarding recent animal drug approvals for additional indications for this combination and other new approvals.

T.K. Cheung Lecture in Animal Science: "Using science to assess and improve the welfare of dairy cattle"

Dan Weary is a Professor at the University of British Columbia. Dan did his BSc and MSc at McGill and Doctorate at Oxford before co-founding UBC’s Animal Welfare Program where he now co-directs this active research group. His research focuses on understanding the perspectives of animals and applying these insights to develop methods of assessing animal welfare and improving the lives of animals. His work has helped drive changes in practices (including the adoption of higher milk rations for calves and pain management for disbudding) and housing methods (including the adoption of social housing for pre-weaned calves). He also studies cow comfort and lameness, social interactions among cows, and interactions between cows, human handlers and technologies like automated millking systems that are increasingly used on farms. His presentation will outline key questions in cattle welfare, highlight recent UBC research addressing them, and showcase innovative methods for improving the lives of cattle and their caretakers.
