Flashcards

Cecum function

The cecum is a part of the digestive system that produces lactic acid and releases volatile fatty acids, important for digestion in some animals. It also has a specific pH to digest indigestible fiber.

Coprophagy

Eating one's own feces to recover nutrients and vitamins from microorganisms in the digestive tract.

Colic symptoms

Colic is a gastrointestinal upset characterized by symptoms such as heat, pawing, rolling, sweating, difficulty defecating, and groaning.

Nutrient Requirements

Nutrient requirements are based on standards to formulate animal diets.

Metabolizable Energy (ME)

Energy that's available and usable by an animal's body, mostly absorbed by epithelial cells. Used for living and muscle function.

Study Notes

Homeostasis: Balanced Energy Needs/Neutral Conditions

  • Cecum:
    • Has natural pH (cellulose & hemicellulose).
    • 1.2 meters long, holding 25-30 liters (like a paint bucket).
    • Produces lactic acid.
    • Releases volatile fatty acids.
  • Coprophagy:
    • Eating own feces to regain microbial nutrients and vitamins.
  • Human feeding frequency changes.
  • Nutrient Requirements:
    • Use NRC (National Research Council) to formulate diets for animals.
    • Kilo = 1000
    • Mega = 1,000,000
  • Adjusting energy based on:
    • Amount of feed.
    • Energy density of the food.
    • Dry matter, fat, protein, carbs
  • Energy calculations:
    • Gross energy: the total energy consumed in the feed.
    • Digestible energy: energy absorbed/retained by the body.
    • Fecal energy: energy lost in the feces.
    • Urine energy: energy lost in the urine.
    • Metabolizable energy (ME): usable energy for the cells (epithelial cells)
    • Energy for living and muscle usage.
    • Net energy (NE): energy remaining after all losses (energy = maintenance).

Colic (Gastrointestinal Upset)

  • Symptoms:
    • Pawing
    • Rolling
    • Sweating
    • Failed to defecate
    • Groaning
  • Causes:
    • Idiopathic (unknown cause)
    • Impaction (sand)
    • Gas/fermentation
    • Strangulation (twisted gut).
  • Hooves:
    • Sensitive to the body's pH.
    • Inflammation can lead to colic.
    • Acidic pH associated with inflammation and colic.
  • Hooves:
    • Lamina (tissue below the hoof)
    • Laminitis = "founder"
