Uso de drogas en ganado lechero
Discúlpeme pero yo no hablo español. Entonces mi respuesta está en inglés. Si no lea o entienda bien, favor de decirme y voy encontrar alguien que escriba español. Gracias por su paciencia!
Since 2003, the U.S. Food and Drug Administration (FDA) has outlawed any use of phenylbutazone (fenilbutazone or “bute”) in dairy cattle older than 20 months. This is because of evidence that bute can cause adverse events in humans, including various blood disorders, bleeding, toxicity, cancer and death. If bute is used in dairy cattle over 20 months of age, there is a potential risk to public health because harmful levels of bute residues can be found in these animals at slaughter.
It is legal to use this medication in beef cattle in the U.S., however. Bute is used as an anti-inflammatory, meaning it reduces heat, pain, redness and swelling in areas that have been damaged by trauma or infection. It does NOT kill bacteria, but it does reduce some of the damage they cause tissues. It can reduce fever.
I hope this is the information you needed. Best wishes,
