Supplementing Antibiotic Mass Treatments May Provide Added BRD

US - Supplementing an antibiotic mass treatment, such as Micotil, with a Pasteurella vaccine, may provide additional protection against Bovine Respiratory Disease (BRD), according to a recent study conducted at Five Rivers Cattle Feeding feedlot (Colorado Beef), in Lamar, Colo. Results showed a combination of Micotil and Presponse SQ from Fort Dodge Animal Health, lowered the morbidity and mortality of light-weight, high-risk calves.

During the study, conducted by Tony Bryant, PhD and Del Miles, DVM, the Micotil/Presponse SQ cattle had a 17 percent lower incidence of first pulls than the Micotil-alone cattle and a 19 percent lower incidence of relapses.

"In the past, it was thought that to benefit from a Mannheimia (Pasteurella) haemolytica vaccination, it needed to be administered during the pre-conditioning period rather than at feedlot arrival," said Frank Prouty, PhD, senior director, Feedlot Services, Fort Dodge Animal Health. "These results demonstrate the real value of administering a Pasteurella vaccine at feedlot initial processing."

The study consisted of nearly 4,000 head of cattle, divided into two treatments. Every calf received the labeled 1.5 mL per hundredweight of Micotil, and every other calf was given a dose of PRESPONSE SQ. The calves were not separated by treatment, allowing them to share common pen conditions, and were managed under standard feedlot procedures.
