Questions and Answers

What is the main difference in the stomach structure between pseudo-ruminants and monogastric animals?

Pseudo-ruminants have enzymes for protein digestion, while monogastric animals lack these enzymes.

Pseudo-ruminants have multiple stomach compartments, while monogastric animals have a single stomach compartment.

Pseudo-ruminants have a simple stomach, while monogastric animals have a complex stomach.

Pseudo-ruminants can regurgitate their food, while monogastric animals cannot. (correct)

Which type of animal does not produce enzymes for protein digestion?

Omnivores

Ruminants (correct)

Carnivores

Herbivores

Study Notes

Ruminant Animals

Stomach is sectioned into rumen, reticulum, omasum, and abomasum, enabling digestion of leaves, grasses, shrubs, and other herbage high in cellulose and hemi-cellulose.
Fibre fractions of these plants are broken down into three short-chain volatile fatty acids (VFAs: acetic, propionic, and butyric acids) by bacteria and protozoans through fermentation.
Four-chambered stomach: cattle, sheep, goats, deer, and giraffes.
Three-chambered stomachs: okapis, pronghorn, camels.

Advantages of Ruminant Pre-Gastric Fermentation

Breaks down fibrous feeds into VFAs, synthesizes vitamins and amino acids, and protein in the rumen.
Synthesizes rumen microbial protein by rumen microbes.
Selective retention of particles occurs at the reticulo-omasum orifice, and mechanical breakdown of fibres during rumination enhances digestion of coarse foods.
Large quantities of gas produced can be readily released from the system by eructation (belching).

Pseudo-Ruminants and Monogastric Farm Animals

Pseudo-Ruminants: animals with simple stomachs that feed on grasses and other materials but do not regurgitate.
Examples: okapis, pronghorn, camels.
Monogastric Farm Animals: have a simple stomach with a single stomach compartment.
Examples: pigs, poultry (chickens, ducks, turkeys, guinea-fowl, and geese).

Non-Ruminant Herbivores

Herbivores that feed on plant materials, but do not have a four-chambered stomach.
Examples: horses, rabbits.
Have a complex large intestine and mono- and poly-gastric capabilities.
Digest cellulose by microbial fermentation in the large intestine and cecum.

Carnivores and Omnivores

Carnivores: obtain their food by feeding on other animals.
Examples: dogs, cats.
Omnivores: feed on both plants and animals.
Examples: pigs, poultry.

Coprophagy/Caecotrophy

Process of re-ingestion of a special kind of faeces (soft faeces), allowing food to pass through the entire digestive tract a second time.
Enables complete digestion and utilization of feed material.
Common in the rodent family (e.g., rabbits, hares).
Prevention of coprophagy/caecotrophy results in:
- Rapid development of deficiencies of vitamin K, biotin, and other vitamins.
- Reduced growth rate, protein utilization, and nitrogen retention.

Types of Farm Animals

Meat Animals: cattle, sheep, goats, poultry.
Dairy Animals: cow, doe, ewe.
Work Animals: bull, mules, bullocks, buffaloes.
