Study Notes

Digestive System Overview

  • Mouth facilitates chewing and prehension, with saliva containing the enzyme amylase to begin starch digestion.
  • Esophagus serves as a muscular tube that connects the mouth to the stomach, aiding food transport.

Rumen

  • Largest compartment of the ruminant stomach, characterized by shag carpet-like texture and large finger-like projections called papillae.
  • Functions as a fermentation vat, where microbial digestion occurs and absorbs volatile fatty acids (VFAs).

Reticulum

  • Known for its honeycomb structure, this compartment acts as a site of fermentation and allows for the regurgitation and rechewing of cud, enhancing digestion.

Omasum

  • Contains many folds resembling a book and is responsible for water absorption while beginning the absorption of nutrients.

Abomasum

  • Referred to as the "true stomach," it secretes lysozyme and acid to aid in enzymatic digestion, resembling the stomach of monogastric animals. It's pear-shaped and has a smooth lining.

Small Intestine

  • Divided into three sections: duodenum, jejunum, and ileum, where almost all nutrient absorption occurs, marking the final site of digestion.
  • The terminal ileum specifically absorbs bile salts, acids, and remaining nutrients.

Cecum

  • Acts as a catchment area for large particles, marking the beginning of microbial digestion.

Large Intestine

  • Comprises three sections: cecum, colon, and rectum.
  • Primarily functions in water absorption and the formation of feces, storing waste until disposal.

Stomach

  • Engages in enzymatic digestion, where food is reduced to a liquid state, with the pyloric region secreting mucus to protect the lining from acid damage.

Cattle Classification

  • European cattle are classified as Bos Taurus.
  • Cattle influenced by Brahman genetics are categorized as Bos Indicus.

Digestive Systems

  • Ruminants possess four stomachs, including cattle, goats, and sheep.
  • Non-ruminants or monogastric animals have a single stomach, such as pigs.

Gestation Periods

  • Horses have a gestation period of approximately 11 months.
  • Cattle typically gestate for about 9 months.
  • Sheep and goats have a shorter gestation period of around 5 months.
  • Pigs have the shortest gestation, lasting roughly 3 months, 3 weeks, and 3 days.

Reproduction Terms

  • Parturition refers to the process of giving birth in animals.
  • Colostrum is the initial milk received by newborns right after birth, rich in antibodies and nutrients.

Animal Classifications

  • Cattle are known scientifically as bovine.
  • Sheep belong to the ovine category.
  • Goats are classified as caprine.
  • Horses are identified as equine.
  • Pigs fall under the porcine classification.
