NOTE

ANATOMY AND PHYSIOLOGY OF FARM ANIMALS

Anatomy is the branch of agricultural biology that deals with the study of the form and structure of the body.
Physiology refers to the function of the forms and structures of the body.

PARTS OF FARM ANIMALS
This is divided into four major groups as follows,
1. HEAD
This is the upper part of the body. The major organs found in the head region are brains, eyes, tongue, ears, mouth and nose.

  1. THORACIC CAVITY
    The thoracic cavity refers to the chest region of the body. The major organs found her are heart, lungs and trachea.
  2. ABDOMINAL CAVITY
    This refers to the stomach region of the body. The Organs in those region are pancreas, liver, uterus, stomach, oviduct, kidneys etc.
  3. LIMBS
    The limbs include the fore limbs and the hind limbs. The limbs are used for walking.

Digestive system
This refer to all organs and tissues associated with breaking down food in the body. It includes the teeth or beak, tongue, alimentary canal, and the associated glands including the secretory enzymes.

CLASSIFICATION OF FARM ANIMALS BASED ON THE DIGESTIVE TRACTS.

Farm animals are grouped into two main classes,
1. MONOGASTRICS OR NON RUMINANT ANIMALS
These animals possess only one stomach and do not chew cud. These non-ruminants have simple
stomach and cannot digest cellulose and fibers properly. Examples are the pig, rabbit, and poultry

  1. POLYGASTRICS OR RUMINANT ANIMALS
    These farm animals which possess four chambered stomach or complex stomach, hence the chew cud.
    The four chambered stomach includes the Rumen, Reticulum, Omasium and Abomesum

EVALUATION:   1. Define anatomy and physiology

  1. State and explain the major parts of the body
  2. Define digestive system
  3. Classify farm animals based on their digestive                              system/mode of feeding

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
