Beak consists of two mandibles

Lower mandible, Upper mandible

secretes saliva to lubricate food for easy swallowing

Salivary gland

dagger-like structure with very rough surface to help force the food into the esophagus

Tongue

Saliva contains an enzyme for starch digestion called?

Amylase

A-pouch-like structure found anterior to the proventriculus for temporary storage of food

Crop

Passage of food from mouth to the crop.

Esophagus/Gullet

An enlargement of the gullet just before the gizzard

Proventriculus

also called the muscular stomach

Gizzard

site for absorption or assimilation of digested nutrient

Small intestines

is also known as the common sewer

Cloaca

functions for water resorption to increase water content of the body cells and maintain water balance in the bird

Large intestines

is also known as anus, the external opening of the cloaca.

Vent

Supplementary digestive organ

Pancreas, Liver, Gall bladder, Salivary glands

composed of two large lobes. It secretes bile acid that enters in the lower end of the duodenu

Liver

composed of two large lobes. It secretes bile acid that enters in the lower end of the duodenum.

Liver

secretes pancreatic juices that pass through the duodenum via pancreatic ducts Pancreatic enzymes are used for digestion of starches, fats and proteins.

Pancreas

found in the buccal cavity which secretes saliva that contains amylase

Salivary glands

Functions for the temporary storage of bile.

Gall bladder

The main function of this is to transfer blood from the heart to the cells of the body and back.

Circulatory System

Sn of pigeon

Columbia livia

Sn chicken

Galus galus domesticus

Shell

encloses the albumen and prevents bacteria to penetrate the eggs interior part.

chalazae

is spherical, yellow to orange in color, and located near the center of the egg.

Yolk

commonly done using incubator machines

Artificial incubation system

done by the mother hen

Natural system

a small building with heat generated on one side from a burning fuel (wood) and conveyed into the whole building.

eggs are pre-heated under the sun or with the use of heated unhulled rice or “palay” in a metal cauldron.

Balutan system

air or forced-draft incubators which can be box-type to mammoth room-like incubator with 50 to hundred thousands of egg capacity, fuelled by electricity or petroleum, or coal and with hot air or hot water circulating from the source of heat.

Modern incubators

any feed constituent, or a group of feed constituents of the same general chemical composition that aid in the support of life

Nutrients

the series of processes by which an animal takes in and assimilates food for promoting growth and replacing worn out tissues

Nutrition

transfer of substance from the gastro-intestinal tract to the circulatory (blood or lymph) system

Absorption

breakdown of feed particles into suitable products for absorption; may include mechanical forces, chemical action, enzyme activity

Digestion

an organic catalyst that speeds up the rate of chemical reaction

Enzymes

combination of anabolic and catabolic reactions occurring in the body with the liberation of energy

Metabolism
