Breeding sheep genetically resistant to parasites

PARARES – Parasite Resistance

Co-financed by the European Union and Greek national funds

The current situation regarding the subject of the project

The infection of sheep with parasites, especially of the genera Teladorsagia and Haemonchus, is a major problem of Greek farms, with direct consequences in the production of milk and meat. The reckless use of antiparasitic drugs, in the context of deparasitication programs, contributed to the development of resistant strains of parasites. The administration of the same antiparasitic preparations for a long time in combination with the under-dosing of the drugs has accelerated the process of natural selection and results in the prevalence of those parasites, which are now able to survive against the antiparasitic drugs.

Under-dosing due to incorrect weight estimates can mean that too often a small amount of drug is given, which may not be sufficient to act on all the parasites in the sheep’s digestive tract. Therefore, some parasites are exposed to a drug concentration lower than the lethal dose of the anthelmintic, developing resistance to future dewormings.

The Innovation

This Operational Plan concerns innovation in the production process of genetically resistant sheep against parasitism in Greece. The innovative elements of the proposal include: The production of genetically resistant clones of sheep to parasitism will lead to a significant reduction in the use and dependence of Greek sheep farming on chemical antiparasitic drugs.

The production of such animals will lead to a high value of the individuals of these clones to be used as nuclei of future generators in this and other breedings (sale of generators). In addition, gradually the strains of parasites in the Greek area will remain sensitive to chemical antiparasitic drugs, which will be able to be used in cases where their use is required.

The objective of Measure 16 is to strengthen the culture of cooperation between the involved bodies with the aim of:

  • strengthening the competitiveness of businesses in primary production (agricultural holdings) in the food sector, mainly local products but also as well as
  • the search for new cultivation practices and production practices that contribute to the protection of the environment but also to adaptation to climate change.

Through the partnerships that will be developed, the opportunity will be given to utilize new technologies and innovative processes for:

  • the production of safer and healthier food.
  • the reduction of water consumption and in general the cost of inputs for economic and environmental benefit
  • ensuring the uniqueness of certified agricultural products
