Dry cow therapy should be used at drying off only. Treatment to be at least 35 days before calving. Orbenin Dry Cow must not be used for the treatment of the lactating cow. If a lactating cow is accidentally infused, milk must be withheld from the bulk supply for 35 days.
Since the period of activity of the formulation is prolonged, it is important that this preparation is not used for the occasional cow which may have a very short dry period of less than 35 days. This will avoid contamination of the milk after the colostrum has been removed. In such cases Orbenin L.A. (ACVM No. A3664) may be used at drying off.
Withholding Periods:
Milk: Milk for human consumption must not be taken from the first 8 milkings after calving. If calving occurs before 35 days after the last treatment, milk to be sold for human consumption may only be taken after the full 35 days from treatment and a further 8 milkings have elapsed. If a lactating cow is accidentally infused, milk must be withheld from the bulk supply for 35 days.
Meat: Cows producing meat and offal for human consumption must not be sold for slaughter during treatment or within 28 days of the last treatment.
Bobby Calves: When a calf is given colostrum from a treated cow that has calved within the 35-day withholding period this calf must, subsequently, be fed milk that does not contain antibiotic residues and withheld from slaughter for 7 days.
