Seconds after application |
|
Disinfectants need time to kill bacteria, although they do not completely eliminate them. These products may be applied externally on the animal body (antiseptics), or on milking equipment (disinfectants). |
|
ANTIBIOTICS |
|
Medications administered to the cow to kill disease causing bacteria. |
|
They do not kill either virus or fungi, and need several days of action to achieve good results. |
|
Antibiotics do not differentiate among “good” and “bad” bacteria, thus, they also kill benign bacteria. In such a case, the body of the cow may not be strong enough to fight new infections. |
|
DANGER: ANTIBIOTICS |
|
• Extended use, or poor antibiotic selection lead to development of antibiotic resistance. Poor selection also favor the development of bacteria resistant to antibiotic. • Antibiotics can destroy benign digestive flora. These good bacteria are important for digestion processes. • In mild cases, the cow can fight the infection on her own without antibiotics. • Antibiotics contaminate milk, and that is hazardous to consumers. • Extra-label use of antibiotics is restricted to veterinarians to determine what, how, when and the appropriated dosage of antibiotic to be used. |
