The IVOMEC® for Swine HM/LE Program.

Protocol #1

  1. Contact your swine veterinarian for an HM/LE program outline, participation requirements and supervision.

  2. Complete the HM/LE Agreement form and order the IVOMEC for Swine Brand Products needed to complete the two dose implementation through Merial. Fax a copy of your agreement form to Merial for approval and to initiate the order of IVOMEC for swine. (Fax # 1-678-638-3500)

  3. Market all hogs reaching market weight or greater.

  4. Treat all pigs on all sites of the farm with IVOMEC for Swine Injection product at the label-recommended dosage on Day 1 of the program.

  5. On days 18 - 21, market all hogs reaching market weight or greater.

  6. On days 18 - 21 retreat all pigs on farm with IVOMEC for Swine Injection product at the label-recommended dosage.

  7. Pigs born between the initial and second treatment should be injected on the day the second treatment is administered to entire herd. Use IVOMEC Injection 0.27% for Grower and Feeder Pigs for accurate dosing on piglets. (Make sure you have a good syringe that can deliver an accurate 1/4 Ml dose.)

  8. All replacement breeding animals (gilts and boars) entering the premises or coming out of the finishing area, must be isolated and treated with 2 doses of IVOMEC Injection for Swine 18-21 days apart before being placed with the other breeding stock. Isolate for at least 7 days following the second injection.

    This is critical for maintaining a mange and lice-free herd. Most re-infestations occur due to improper treatment and isolation of new incoming or replacement animals.

Practical Tips for HM/LE Implementation

    For IVOMEC Injectable products use a 16 gauge 3/4 inch needle to be administered subcutaneously in the neck region. An 18-20 gauge needle may be more appropriate for small pigs.

    When determining proper dosage with IVOMEC, follow label instructions. Pigs must not be treated within 18 days of slaughter with IVOMEC Injection for Swine.

    It is encouraged to weigh a few pigs to get a good idea of animal weights. When estimating the weight of a group of hogs, set your syringe for the largest animal in the group.

    Do not under-dose. If a sow weights 450 lb. and your syringe is a pistol grip model, delivering a maximum dose of 5 mL per squeeze, set your syringe at 3 mL and squeeze twice. If they weigh 600 lb., set the syringe at 4 mL and squeeze twice.

    Consider any animal coming to the herd from an outside source to be infested. All new arrivals must go through the two-dose treatment and isolation as outlined in the HM/LE guidelines. Isolation relative to external parasites requires no physical contact of infested animals with uninfested (clean) animals. This means a solid partition (wall, building) between animals free of parasites and those that may be infested.

    Basic herd biosecurity practices should be followed to prevent re-introduction of lice or mange. Herd biosecurity procedures include proper isolation, pig flow, workers clothing and boots, and traffic from potentially infested areas to uninfested areas.1-4
