Sheep Eye Colour Chart
6. Immediately hold the FAMACHA color chart next to the exposed eyelid and compare the color of the animal's membrane to the color blocks on the card. Do this in good light (preferably natural daylight).
Decide which color category (1 through 5) the eye color matches best. A. FAMACHA© is a color eye chart that estimates the level of anemia (blood loss) in sheep/goats (and camelids).

Anemia is the primary symptom of barber pole worm (Haemonchus contortus) infection. It is also a symptom of liver fluke disease. The FAMACHA© card displays five color and treatment categories.
The study was undertaken to develop and evaluate a colour chart to identify degree of anaemia in sheep of Rajasthan for management of haemonchosis and maintaining the anthelmintic susceptibility. The FAMACHA© card is a tool that matches the color of the eye mucous membranes of small ruminants. It contains a colour chart showing 5 colour categories that correspond to different levels of anaemia.

The FAMACHA© card, developed in South Africa, was introduced to the U.S. by the American Consortium for Small Ruminant Parasite Control (www.acsrpc.org). It is a tool that matches the color of the eye mucous membranes of small ruminants with a laminated color chart showing 5 color categories that correspond to different levels of anemia.
Category 1 represents "not anemic" with category 5. The FAMACHA chart refers to an anemia guide developed by Dr. Faffa Malan.

A chart of five different colors, it corresponds directly to the color of a goat or sheep's lower eyelid. If your sheep's eyelids are pale pink to white, they are severely anemic and need to be dewormed ASAP. The scale works from there.
Sheep with white eyelids are believed to be possessing fatal levels of parasites. The FAMACHA© eye anemia system was developed almost 30 years ago by South African researchers in response to increasing dewormer resistance. FAMACHA© is a color eye chart that estimates the level of anemia (blood loss) in small ruminants.
Anemia is the primary symptom of the barber pole worm (Haemonchus contortus), the primary worm affecting small ruminants in warm, moist climates. To. The Famacha (FAffa MAlan CHArt) system was developed in South Africa by Drs Francois Malan, Gareth Bath and Jan van Wyk after the emergence of drug-resistant worms.
It involves studying the colour of the mucous membranes of the eye in sheep or goats. Anaemia is assessed using a chart (see Table 1. The "FAMACHA" chart (Fig.
1) assigns a number from 1 to 5 to each level of colour in the eyelid. A normal eyelid of a healthy sheep or goat is dark red, indicating that no anaemia is present and the animal is presumed to be free of dangerous levels of parasites. The percentage of sheep recommended for treatment decreased from 44.6% for eye scores of 3,4 and 5 to 12.9% for eye scores of 4 and 5 [(true positive + false positive)/total number of sheep x 100].
A similar trend was seen with goats, but percentage of goats requiring treatment was higher.
