Thats great, glad they are trying to save you money. The product does work well! Just a FYI, I did a cost comparison at our feedlot, as we were using the GENERIC product called Duramycin 200 or Terra-Vet 200(these are generics to the LA-200), but they only last 3 days per injection instead of the 5 days like Noromycin.
If you give 2 doses of Duramycin/Terra-vet 200(for a total of 5-6 days coverage) to a 550# calf, or ONE DOSE of Noromycin 300, for 5 days coverage, it only costs you approx .50c more per calf to use the Noromycin 300. Research shows it costs approx $3.00/head everytime you run an animal through the chute due to lost weight gain, injuries to feet, shoulders, etc. Hope this helps everyone.
