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.
Important Birth-Related Facts
- 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.
