Read Entire Package Insert Carefully Before Using This Product
MastiShield is a sterile, antibiotic-free, off-white smooth paste. It is presented, ready to use, in syringes, each containing 4 g of intramammary infusion composed of 65% Bismuth Subnitrate, in a mineral oil vehicle. MastiShield is indicated as an aid in the prevention of new intramammary infection throughout the dry period by providing a malleable barrier in the teat canal. This results in a reduction in the incidence of clinical mastitis in the dry period.
It is recommended that MastiShield be used as part of a herd approach to dry cow management and mastitis control.
WITHDRAWAL INFORMATION: For use in dry cows only. Zero-day milk and meat withdrawal when used alone.
If MastiShield is administered following an antibiotic infusion, the withdrawal periods for meat and milk for the antibiotic must be observed.
PrecautionsKeep out of reach of children. For animal treatment only. If MastiShield gets on skin, wash with soap and warm water. If accidentally administered to a lactating cow, product can be stripped out by hand. An SDS may be obtained by calling Norbrook at 1-866-591-5777 or visiting the Norbrook, Inc. website at www.norbrook.com.
Adverse ReactionsMastitis-causing bacteria introduced into the teat at the time of infusion of MastiShield have been associated with adverse reactions. Each teat must be cleaned and disinfected prior to infusion of MastiShield. See below for instructions for administration of infusion products.
StorageMastiShield should be stored at room temperature 59°-86°F (15°-30°C). In very cold temperatures MastiShield may become difficult to administer and should be warmed to room temperature. Individual tubes should not be immersed in water. The MastiShield bucket can be lowered into a 5 gallon bucket filled with warm water to warm the tubes.
MastiShield is intended as an aid in the prevention of new intramammary infections of dairy cattle throughout the dry period.
Dosage and AdministrationAfter last milking at dry-off, clean and disinfect the teats with the alcohol wipes provided. Gently pinch the base of the teat near the udder attachment to close the teat canal. Infuse entire contents of one syringe of MastiShield into each quarter by inserting the nozzle into the teat and applying gentle continuous pressure to the plunger until the paste is expressed. MastiShield must remain in the teat canal to be effective.
Do not massage teat or udder following infusion. If an antibiotic is infused into the teat, the teat should be re-wiped with the alcohol wipe provided prior to infusion with MastiShield. A clean, disinfected and dry teat is essential, as MastiShield possesses no antimicrobial activity. It is advisable to use an appropriate teat disinfectant following the infusion.
MastiShield is presented in syringes with a 2-Stage tip. This 2-Stage tip allows for either full or partial insertion into the teat orifice. Partial insertion only is preferable, as it may prevent unnecessary damage to the teat orifice and reduce the risk of infection. Full insertion may be needed for large teat orifices.
Option 1: For short tip intramammary administration
Option 2: For long tip intramammary administration
REMOVAL: Do not remove MastiShield by action of the milking machine.
To reduce the potential for MastiShield accumulation in milking machines, aggressively hand-strip MastiShield out of every quarter, 10 to 12 strips per quarter, before milking fresh cows. Bucket-milk fresh cows for a minimum of three milkings, if possible.
Simple steps to avoid introducing infections during administration of intramammary infusions.
1. Do not place individual syringes in warm/hot water during cold weather.
2. Dry cows off abruptly rather than gradually.
3. Clean teat ends as thoroughly as possible with alcohol wipe and leave to air dry. DO NOT use water with or without disinfectant.
4. Clean the two teats furthest away first, followed by the two closest.
5. Ensure the teats are clean and dry before infusing MastiShield.
6. Infuse the teats in the opposite order to cleansing: i.e. infuse the closest two teats first, followed by the two furthest away.
7. After infusing, dip teats in teat dip or spray with disinfectant and leave cows standing in yard for at least half an hour to allow the teat canal to close.
8. Check cows regularly for signs of mastitis during the first week after drying off.
