    Study Notes

    Horse Anatomy and Digestive System

    • The most common site of feed impactions in horses is the esophagus.
    • The horse lacks a gallbladder.
    • The equine hoof has a sensitive laminae located within it.

    Ruminant Anatomy and Digestive System

    • Ruminants have a type of placentation called epitheliochorial placentation.
    • Adult cattle have a dental pad instead of upper incisors, with no upper incisors or canines.
    • Ruminants gain energy from volatile fatty acids (VFAs), a product produced by microbes during fermentation.
    • Fermentation occurs in the rumen and large intestine in horses.
    • The largest organ in the equine body is the liver.

    Horse Limbs and Movement

    • The equestrian term for the 'knee' in the forelimb of a horse is the carpus.
    • The equivalent of the 'knee' in the forelimb of a horse in humans is the carpus.
    • The most distal structure on a horse's leg is the hoof.

    Ruminant Digestive Process

    • Ruminants rely on volatile fatty acids (VFAs) for energy production from fermentation.
    • Fermentation occurs in the rumen and large intestine in horses and ruminants.

    Ruminant Health

    • The condition commonly known as 'Bars Founder' in horses is laminitis.
    • Most microbial fermentation takes place in the rumen in ruminants.
    • The rumen is the digestive compartment that collects sharp objects, causing hardware disease.
    • The reticulum is the smallest ruminant forestomach and is most involved in hardware disease.
    • The omasum is the ruminant forestomach responsible for dehydration and grinding feed.
    • The abomasum is the compartment in ruminants considered the true stomach.

    Reproduction

    • The gestation period in mares is approximately 320-340 days.
