Genome‐wide association study to identify genetic loci associated with gastrointestinal nematode resistance in Katahdin sheep

Animal Genetics, Volume 51, Issue 2, Page 330-335, March 2020., 2020
Summary Resistance to gastrointestinal nematodes has previously been shown to be a moderately heritable trait in some breeds of sheep, but the mechanisms of resistance are not well understood. Selection for resistance currently relies upon faecal egg counts (FEC), blood packed cell volumes and FAMACHA visual indicator scores of anaemia.

Identification of genomic regions and candidate genes of functional importance for gastrointestinal parasite resistance traits in Djallonké sheep of Burkina Faso [PDF]

Archives Animal Breeding, 2019
A total of 184 Djallonké lambs from Burkina Faso with phenotypes for packed-cell volume (PCV), log-transformed fecal egg count (lnFEC), and FAffa MAlan CHArt (FAMACHA©) eye scores were typed with the OvineSNP50 BeadChip of Illumina to contribute to the ...

Field evaluation of FAMACHA in detecting haemonchosis in indigenous sheep of Tamil Nadu: Correlation with volume of packed red cell and faecal egg count

Journal of Veterinary and Animal Sciences
The FAMACHA system was developed in South Africa and has been tested in various geographical regions on sheep for targeted selective treatment with anthelmintics against gastrointestinal parasitism, particularly Haemonchus contortus.

Genetic parameters for body weight, worm resistance, packed cell volume and FAMACHA@ under natural infection in Corriedale sheep.

, 2022
.Gastrointestinal parasites (GIP) are one of the main constraint for sheep production worldwide. In Uruguay, the most prevalent and pathogenic parasite is Haemonchus contortus. One approach to control parasite infection is to select genetically resistant

Implementation of Targeted Selective Treatment (TST) in a Commercial Smallholder Sheep Flock: Reduction in Anthelmintic Expenditure

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
ABSTRACT The adoption of targeted selective treatment (TST) is an alternative for the sustainable management of gastrointestinal nematodes in sheep. TST mitigates the development of anthelmintic resistance by reducing the number of animals drenched while preserving the parasite refugia population.

The FAMACHA system for managing haemonchosis in sheep and goats by clinically identifying individual animals for treatment [PDF]

Veterinary Research, 2002
Escalating anthelmintic resistance has made it essential to develop alternative ways of worm management for reducing selection for worm resistance, and one of the most promising approaches is to treat only those animals unable to cope with worm challenge, thus favouring unselected worms originating from untreated animals.

FEC Check: Development of a decision support tool to aid interpretation of gastrointestinal nematode faecal egg counts in sheep

Veterinary Record, Volume 198, Issue 9, Page e373-e384, 2/9 May 2026.
Abstract Background Gastrointestinal nematode infections are ubiquitous in grazing livestock worldwide impacting animal health and production. Faecal egg count (FEC) is an accessible diagnostic test that can guide the need for treatment. However, interpretation of FECs can be challenging.
