(cloxacillin benzathine intramammary infusion)
Shortest required dry period with zero milk withhold post-calving.
ORBENIN-DC™ (cloxacillin benzathine intramammary infusion) delivers targeted treatment of Gram-positive bacteria with the shortest required dry period – only 28 days – and no milk withhold. So fresh cows can move into the milking string faster.
Targeting the most common type of subclinical mastitis.
More than 94% of cows with subclinical mastitis at dry-off are infected with Gram-positive bacteria (environmental staphs and streps).1,2 Gram-negative infections such as E. coli usually self-cure during lactation, making ORBENIN-DC an ideal choice at dry-off.
- Reduces the rate of clinical coliform mastitis 2.4-fold greater than ENVIRACOR® J-5 during the first 100 days of lactation.2
- The greatest difference in efficacy over ENVIRACOR J-5 was in cows at higher risk – those third lactation and higher.2
- No negative effect on milk production.2
Orbenin-DC is indicated in the treatment and prophylaxis of bovine mastitis in nonlactating cows due to Staphylococcus aureus and Streptococcus agalactiae.
Because cloxacillin benzathine is relatively insoluble, Orbenin-DC’s activity will be prolonged. Therefore, Orbenin-DC should not be used for the occasional cow which may have a dry period of less than 4 weeks. This precaution will avoid residues in the milk following removal of the colostrum.
Because it is a derivative of 6-amino-penicillanic acid, Orbenin-DC has the potential for producing allergic reactions. Such reactions are rare; however, should they occur, the subject should be treated with the usual agents (antihistamines, pressor amines).
At the last milking of lactation, milk the cow out normally. Clean and disinfect the teats with alcohol swabs provided in the carton or pail, and infuse 1 syringe of Orbenin-DC, which has been warmed to room temperature, into each quarter. Do not milk out. The cow may be milked as usual when she calves.
The extent of subclinical and latent mastitis in a herd is frequently greater than suspected. In untreated herds a significant buildup of subclinical mastitis may occur during the dry period, which results in clinical severity after a few lactations. The adverse influence of subclinical mastitis on milk yield, the risk of cross-infection, and the chance of clinical mastitis flare-up make it necessary to treat the matter as a herd problem. Clinical studies have proven the value of treating all the cows in heavily infected herds as they are dried off. When the herd infection has been reduced, it may be desirable to be more selective in treating infected quarters.
Each carton contains 12 alcohol swabs to facilitate proper cleaning and disinfecting of the teat orifice.
Each pail contains 144 alcohol wipes to facilitate proper cleaning and disinfecting of the teat orifice.
- Infuse one tube of ORBENIN-DC, warmed to room temperature, into each quarter.
- Syringes have a short tip for fewer intramammary infections.
- Compared to full insertion, partial insertion has been shown to reduce new infection risk by 50%.3
Cartons of 12 single-dose (7.5 g), disposable syringes with 12 alcohol swabs.
Pails of 144 single dose (7.5 g), disposable syringes with 144 alcohol wipes.
Each disposable syringe contains 500 mg of cloxacillin as the benzathine salt in 7.5 g of suitable base.
Do Not Store Above 24°C (75°F)
For use in dry cows only. Do not use within 4 weeks (28 days) of calving. Treated animals must not be slaughtered for food purposes within 4 weeks (28 days) of treatment.
ORBENIN-DC is an intramammary infusion containing benzathine cloxacillin that targets Gram-positive bacteria.
Research has shown that ORBENIN-DC is as effective as leading competitors in treating and preventing mastitis in dry cows.
This non-inferiority study found no difference based on clinical mastitis, somatic cell count, reproductive performance and milk production.

The dry period is an important time to minimize mastitis risk and vaccinate cows to protect their calves from scours. Give your dry cows the complete care they deserve.
