Animals with chronic anemia have had time to accommodate, and their clinical presentation is usually more indolent with vague signs such as: These animals may have similar physical examination findings such as pale mucous membranes and weak peripheral pulses. An M:E ratio of <1 indicates that red cell production is greater than white cell production; with an M:E ratio >1, the opposite is likely. RBC size is expressed by the mean corpuscular volume (MCV) in femtoliters and can reflect the degree of regeneration. In sheep and goats, the presence of anemia is best assessed by checking the color of the mucous membranes of the eye (easy to do with a FAMACHA© card, Figure 1). Common symptoms in sheep include depression, paler-than-usual gums and eyelids, weakness, anorexia, diarrhea and an accumulation of fluid under the jaw called "bottle jaw. Anemia is an absolute decrease in RBC numbers, hemoglobin concentration, or PCV. This site complies with the HONcode standard for trustworthy health information: Sheep become infected with worms when they graze.

Presence of petechiae or ecchymotic hemorrhage suggest significant thrombocytopenia or thrombocytopathy. This particular worm lives in the sheep’s true stomach, the abomasum. Microcytosis (a decrease in the MCV) is the hallmark of iron-deficiency anemia and can also be heritable in Akitas. Splenomegaly, abdominal distention, and/or heart murmur may be present, depending on the underlying cause of anemia. Because anemia is the principle clinical problem, mucous membrane pallor is one of the easiest ways to monitor sheep, and has proven effective as a diagnostic approach. Terms used for description of abnormalities with MCHC include normochromia and hypochromia. Anemia Caused by Blood Loss If you suddenly lose a large volume of blood, you may be treated with fluids, a blood transfusion, oxygen, and possibly iron to help your body build new red blood cells. Questions might include duration of clinical signs, history of exposure to toxins (eg, rodenticides, heavy metals, toxic plants), drug treatments, vaccinations, travel history, and any prior illnesses. Bruising or bleeding may be signs of a coagulopathy and indicate the need for a coagulation profile. His complete blood count (CBC) shows a decreased packed cell volume (PCV), decreased mean corpuscular volume (MCV), and decreased mean corpuscular hemoglobin concentration (MCHC). Biopsies and aspirates are complementary: biopsies are better to evaluate the architecture and degree of cellularity of the marrow, and aspirates allow for better evaluation of cellular morphology. It thrives there by the thousands by piercing the stomach and sucking blood. Anemia is a life-threatening illness to goats from which they will not recover until you have administered the appropriate dewormer to kill the worms causing the problem and begin a long-term treatment with Vitamin B 12 injections and iron supplements.

Also see Pet Health content regarding anemia in dogs, anemia in cats, and anemia in horses. This value should be corrected for the degree of anemia to evaluate the degree of regeneration. If hemolytic disease is suspected, blood can be evaluated for autoagglutination, or a direct Coombs’ test might be indicated. Abnormalities in RBC morphology, such as basophilic stippling, can indicate lead intoxication. Treatment: Give selenium and vitamin E by injection. FAMACHA scores are given to determine the severity of anemia. Producers should assess the herd or flock’s general health on a regular basis, including vital signs, body condition, and coat. Anemia is classified as regenerative or nonregenerative (see Table: Assessment of Regeneration in Anemia). Most infections are not symptomatic! Diagnosis can be made by CBC, but may be refined by additional tests. Underdosing promotes the development of drug-resistant worms. A complete history is an important part of the evaluation of an anemic animal. Again, the level or severity of anemia in goats and sheep can be determined with a FAMACHA test. If the CBC reveals a decrease in more than one cell line, possibly indicating hypoplastic marrow, a biopsy would be indicated along with an aspirate. Treatment and Recovery. After they consume the infective larvae on the pasture, the larvae develop into adult worms and lay eggs inside of the sheep's digestive tract. Plasma protein can be useful in classifying the underlying cause of anemia. Exceptionally large numbers of worms were recovered from seven of the 14 sheep that were culled because of age at the end of the trial, but these were reflected neither in their faecal worm egg counts, nor, with one exception only, in clinical signs. Anemia can be defined as regenerative or nonregenerative and is based on classic findings noted on a CBC or blood smear evaluation. Iron stores can also be evaluated by Prussian blue staining. Acute anemia can result in shock and even death if more than a third of the blood volume is lost rapidly and not replaced. The principal stomach worms of sheep and goats are Haemonchus contortus, Teladorsagia (Ostertagia) circumcincta, Ostertagia trifurcata, Trichostrongylus axei (see Gastrointestinal Parasites of Cattle), and in some tropical regions, Mecistocirrus digitatus. A blood smear should be evaluated for abnormalities in RBC morphology or size and for RBC parasites. Yes. Anemia, however, can be caused by various other forms of internal blood loss. An absolute reticulocyte count (measured by RBCs/μL × reticulocyte percentage) of >50,000/mcL in cats or >60,000/mcL in dogs is considered regenerative. disproportionate to the anemia seen in chronic disease situations in adult camelids and small ruminants.
