Read the first 7 Small Ruminant Herd Health flashcards as text

  1. Which internal parasite is most commonly associated with 'bottle jaw' (submandibular edema) in sheep and goats?

    Answer: Haemonchus contortus

    Haemonchus contortus is a blood-sucking abomasal nematode that causes hypoproteinemia and subsequent submandibular edema known as 'bottle jaw.'

  2. The FAMACHA scoring system in small ruminants is used to assess which clinical parameter?

    Answer: Conjunctival mucous membrane color

    FAMACHA evaluates the color of the ocular conjunctival mucous membranes to estimate anemia caused primarily by Haemonchus contortus infestation.

  3. Caseous lymphadenitis (CLA) in small ruminants is caused by which organism?

    Answer: Corynebacterium pseudotuberculosis

    Corynebacterium pseudotuberculosis causes CLA, characterized by abscess formation in superficial lymph nodes and internal organs of sheep and goats.

  4. Which vitamin deficiency in young small ruminants leads to 'white muscle disease' (nutritional myodegeneration)?

    Answer: Vitamin E and selenium

    Deficiency of vitamin E and/or selenium causes white muscle disease, a degenerative myopathy affecting cardiac and skeletal muscles in young lambs and kids.

  5. What is the primary transmission route of Maedi-Visna virus (ovine progressive pneumonia) in sheep?

    Answer: Close respiratory contact and colostrum/milk

    Maedi-Visna is a lentivirus transmitted mainly through close respiratory contact and ingestion of infected colostrum or milk from dam to offspring.

  6. Which reproductive disorder of ewes results from Campylobacter fetus subsp. fetus and causes late-term abortions?

    Answer: Vibriosis (Campylobacteriosis)

    Campylobacter fetus subsp. fetus causes ovine vibriosis, an important cause of abortion storms occurring in the last trimester of pregnancy in ewes.

  7. A goat herd experiences sudden deaths in does within 24 hours of parturition. Necropsy reveals hemorrhagic abomasitis. Which clostridial disease is most likely?

    Answer: Clostridium perfringens type C

    Clostridium perfringens type C produces beta toxin causing hemorrhagic enteritis and sudden death, particularly in neonates and periparturient does.
