Aim: To avoid abortion due to health risks and infections (management & vaccination)

Description:

Control of abortion in sheep (the common causes), by Kim Hamer VetMB, MRCVS, CertAVP (sheep)

Learn more about controlling abortion online.

This is an easy to access resource for farmers, intended to provide information on major methods of abortion control in sheep in Europe.  

Brief summaries of the abortion causes and links to the relevant control methods can all be accessed from the main menu.

Other information relevant to abortion control:

 Management :

  • Quarantine and test  any new animals coming to the farm (for Toxoplasmosis, Border Disease, Enzootic Abortion)
  • Control any stray animals such as cats and do not use  any bedding/hay bales that may have been in contact with the cat’s faeces (Toxoplasmosis)
  • Isolate, treat or cull any diseased animal, do not breed further from them (especially for Ovine Pulmornary Adenocarcinoma).
  • For OPA, areas that housed suspect sheep should be disinfected.
  • Try and minimise close contact between sheep. Reduce the time they are housed and reduce stocking densities.
  • Trough feeding increases close contact between sheep.  Feeding on the ground with a snacker may be a safer route.  Licks and buckets are another possible way of passing infection between sheep.

Vaccination (if necessary. Note that no vaccine exists for OPA) :

  • Toxoplasmosis : vaccinate breeding ewes with Toxovax® prior to pregnancy (at least 3 weeks prior to mating). The whole female breeding flock should be vaccinated initially, then any replacements vaccinated annually. 

Expected benefits: If risks are controlled, then high barren rates in ewes is reduced

Prerequisites and/or limits (knowledge, training, capabilities, cost, management, facilities, equipment, etc.)

  • Farmers need to be aware of risks on their farm and managed pastures, shed and new animals accordingly to minimize them
  • Farmers need to know when and how to vaccinate
  • Farmers need to keep and administrate  their vaccines properly
