EMA’s Recommended Vaccination Schedule

Deworming Schedule (revised 12-5-13)
OPTION #1
Foals:
Every 2 months starting at 1st month of life.
Need to use Strongid (Pyrantel Pamoate) at 2Xs the dose against tapeworms, twice per year.
Rotate dewormer between Strongid, Anthelcide, and Ivermectin.
Yearlings, Adults:
Every 2 months.
Need to use double dose Strongid (Pyrantel Pamoate) against tapeworms, twice per year.
Rotate dewormer between Strongid, Anthelcide, and Ivermectin.
Fecal egg counts should be performed at least twice per year to determine efficacy of deworming program. These fecals should be obtained 10 days after deworming.
*Ivermectin: .09 mg/lb, only one that will kill bots, won’t kill tapeworms or encysted small strongyles.
*Pyrantel Pamoate (Strongid): 3mg/lb won’t kill bots or small strongyles, double dose (6mg/lb) will kill tapeworms, so recommended on first trip to pasture.
OPTION #2
Due to resistance developing on some farms that have been on a rotational schedule for years and due to increasing knowledge about parasites, some farms may be better served by developing a rigorous program of fecal egg count monitoring and selective deworming. Talk to your veterinarian to decide which approach works best for your farm and your horses.
An example of a deworming / fecal monitoring program:
Broodmares, Teasers and Stallions:
Do not need to perform fecal egg counts 10 days after deworming; instead, need to identify the heavy strongyle egg shedders (>500 epg). Therefore, perform fecal egg counts 2 months after deworming – will need to do this once or twice a year until these individuals are identified. About 20% of this group will typically fall into the heavy shedder group. Also, all new shipped-in horses should have fecal egg counts performed.
Deworm this group 4 times yearly – twice with an Ivermectin product, one administration should be plus praziquantel AND alternate with double dose Strongid 2 times. Heavy shedders can add additional deworming as recommended by your veterinarian.
Foals up to 1 year:
At 2 months of age – deworm for ascarids with Anthelcide.
At 4 months of age – deworm for ascarids with double dose Strongid.
Before weaning (2 to 4 weeks prior) – perform fecal egg counts to determine if medication is needed for ascarids and /or strongyles and deworm as recommended by your veterinarian. Also, all new shipped-in foals over 2 months should have fecal egg counts performed.
At approximately 9 months of age (late fall) – deworm for strongyles and tapeworms with Ivermectin plus praziquantel.
Perform fecal egg counts on all yearlings prior to the 11-12 month deworming.
At approximately 11 to 12 months of age (winter – after the New Year) – deworm for strongyles and tapeworms with double dose Strongid.
Yearling to 3 year olds:
Do not need to perform fecal egg counts on this group; unless recommended by your veterinarian. Also, all new shipped-in horses should have fecal egg counts performed.
On May 1st (at start of grazing season) – deworm for strongyles with an Ivermectin plus praziquantel product.
On July 1st – deworm for strongyles and tapes with double dose Strongid.
On Aug. 15th – deworm for strongyles and tapes with Ivermectin.
On Oct. 1st – deworm for strongyles with double dose Strongid.
Vaccination Schedule (revised 12-5-13)

January
- Potomac Horse Fever
*Mares with no history of PHF vaccination need a series of two injections, one month apart, for initial vaccination.
March
- West Nile Virus
*Give to all mares due to foal after March
*Mares that ship in and have no history of having been vaccinated for West Nile Virus should be vaccinated upon arrival to farm, and then given a booster in one month.
July

*Any mares with uncertain vaccination history, not including rabies and botulism, will need two primary immunizations spaced three to four weeks apart.
*M protein strangles vaccine (I.M.) for all horses, regardless of age.
*When a pregnant mare arrives at the farm, we must ascertain what Rhino product was being used previously. That product is to be continued, if at all possible, for the duration of the pregnancy, and then the mare may be changed to the farm product post-foaling.
