Dosage and Administration

Dosage and Administration

Oestrous (estrus, oestrus, estrous) is likely to occur 36 hours to 48 hours following sponge removal and ovulation after a following 24 hours. Induction of oestrous (estrus, oestrus, estrous) is enhanced following the use of PMSG 2 days before or at the time of sponge removal.

Insert the sponge by using the applicator. Disinfect the applicator in either a 10% benzalkonium chloride solution or 5g/L chlorhexidine gluconate solution. Do not immerse the sponge in disinfectant. Using a gloved hand insert the sponge into the end of the applicator so that the sponge is just behind the end of the applicator tube, leave the string hanging free. Insert the applicator 10cm to 15 cm into the vagina and gently eject the sponge by pushing the applicator
plunger. Remove the applicator so that the drawstring is hanging outside the vagina. Wipe the applicator clean and re-immerse in disinfectant after each use.

Sponge removal – gently pull on the string to remove the sponge. Some discharge may occur which is normal. If no string is visible carefully examine the vagina to locate the string and remove the sponge.

Mating

• Does – Mate or AI 36 to 48 hrs after sponge removal. If AI is
  used preferably administer a double dose of semen.

• Sheep – Mate at 48 hrs and 60 hours after sponge removal, or AI
  55 hours (48hrs to 60 hrs) after sponge removal. Preferably increase
  the number of rams in the flock to at least 1 ram per 10 ewes. Where
  teaser rams are used, inseminate any unmarked ewes at 72 hours after
  sponge removal.

• Do not use alcohols, cresols, phenols or sheep dips as disinfectants
  on the sponges or applicator.

• Goats may resent sponge insertion, take care and insert the sponge
  gently to avoid the doe moving suddenly and injuring herself.

• If the sponge appears to have adhered to the vaginal wall, carefully
  reinsert the applicator and remove the sponge by exerting tension
  on the sponge through the applicator.

• To avoid animals eating the sponges, burn or bury sponges once
  removed from the animal.
