When it comes to bovine respiratory disease (BRD), time is of the essence. Whether controlling or treating BRD, it’s important to kill bacteria to let the calf’s immune system get back to work. It’s not about how long a drug stays “on board” the cattle’s system, but how effectively the drug works to eradicate the bacteria that cause BRD. Use Baytril 100 first to reduce the bacteria load in high-risk cattle right off the truck.
Stressors such as weaning, shipping, processing, ration change, overcrowding, commingling and adverse weather compromise a calf’s immune system. A variety of viruses (IBR, BVD, BRSV and PI3) can invade and damage the calf’s respiratory tract, which compromises its natural defense mechanisms, including the ability to expel bacteria and dust from the lungs. This damage, along with a suppressed immune system, permits the invasion of BRD-causing bacteria such as Mannheimia haemolytica, Pasteurella multocida, Histophilus somni and Mycoplasma bovis.
