Virtual Chicken: Full Digestive System
zhlédnutí 4,1MPřed 4 lety
Take a tour through the chicken digestion process. For More Information About Chicken Digestion and Nutrition visit virtualchicken.com
Virtual Chicken: The Cloaca
zhlédnutí 167KPřed 4 lety
The large intestine connects to the front part of the cloaca. This organ is a flexible cavity that represents the junction of the digestive and urinary tracts. In hens, the reproductive tract also joins at the cloaca. Here digestive waste mixes with urinary waste and passes out of the body through the vent. The cloaca in chickens is also flexible enough to accommodate an egg passing through it ...
Virtual Chicken: The Proventriculus
zhlédnutí 20KPřed 4 lety
After the food leaves the crop via peristaltic action, it moves into the proventriculus. Also known as the “true stomach”, the proventriculus is where actual digestion begins. The walls of the proventriculus are thick and composed of five layers: a muscle layer, itself composed of three individual layers, a thick layer of glandular tissue, and the inner mucous membrane layer. The glandular tiss...
Virtual Chicken: Small Intestine
zhlédnutí 13KPřed 4 lety
Feed passes from the gizzard into the small intestine where digestion and absorption occur. The small intestine of a mature chicken is more than four and a half feet in length and has three distinct areas; the duodenum or the duodenal loop where the pancreas lies in the center, the jejunum, and the ileum. Collectively the jejunum and ileum are called the lower small intestine. As food leaves th...
Virtual Chicken: The Ceca
zhlédnutí 13KPřed 4 lety
The ceca are two blind pouches located where the small and large intestines join. Some of the water remaining in the digested material is reabsorbed here. Additionally, any remaining course materials are broken down in the ceca through fermentation. During this fermentation process, the bacteria in the ceca produce several fatty acids as well as the eight B vitamins (thiamine, riboflavin, niaci...
Virtual Chicken: The Crop
zhlédnutí 13KPřed 4 lety
In the chicken digestive system, the crop is an extension of the esophagus. It is a thin-walled pouch at the base of the thoracic section of the esophagus. The walls and lining of the crop are made of the same 4 layers as the esophagus: the mucosal, submucosal, muscle tunic, and the serosal layer. The main function of the crop is to hold food in storage until it can be released to the stomach o...
Virtual Chicken: The Esophagus
zhlédnutí 10KPřed 4 lety
The esophagus of a chicken is a thin-walled, expansive tube that transports food from the mouth of the pharynx to the stomach. As food moves towards the back of the tongue, the choana reflexively closes. In the pharyngeal phase, the infundibular mound and glottis close, the tongue is moved backward, and the esophagus is moved forward, decreasing the distance between the oral cavity and the esop...
Virtual Chicken: The Gizzard
zhlédnutí 73KPřed 4 lety
The Gizzard or ventriculus is the muscular stomach where the grinding of food takes place. After being softened by the Proventriculus, food moves into the gizzard. It is a round organ with two lobes, one larger than the other. Each surface in the gizzard is covered by a shiny layer of tendinous tissue which is thicker at the center and thinner out by the edges. Under this outer layer are locate...
Virtual Chicken: The Large Intestine
zhlédnutí 7KPřed 4 lety
The Large Intestine, at 4 inches in length, is actually shorter than the small intestine. It runs in nearly a straight line below the vertebrae and ends at the cloaca. Sometimes this section is referred to as the colon. The last of water reabsorption occurs in this organ creating and storing the undigested waste material that is eventually excreted through the Cloaca. For More Information About...
Virtual Chicken: The Mouth
zhlédnutí 161KPřed 4 lety
The gastrointestinal tract of an avian is unique in comparison to those of mammals; it contains an intestinal tract that is shorter than that of mammals. The digestive tract begins with the mouth. Chickens don’t have teeth or jaw muscles, instead, they have a lightweight beak to swallow food particles whole. These particles are later broken down by the ventriculus, or gizzard, which is located ...

    I used the transcript to make a worksheet for homeschool, just wanted to share here in case anyone else wants to do the same. 1. OVARY When a hen is actively laying, nutrients from the food she eats are converted into the building blocks of egg yolk. These building blocks, one-third protein, one-third fat and one-third water, are then carried by the bloodstream from the liver to the ovary. In the ovary, tiny tissue bags called, follicles, fill with yolk and grow. The largest follicle on the ovary will release the yolk of the egg the hen will lay tomorrow, while the next largest will produce the next day's yolk, and the next largest will yield the next day's yolk and so on. In one to two weeks, a follicle grows from less than one millimetre in diameter to the mature size of 25 millimetres. When a yolk matures, the follicle ruptures along a line relatively free from blood vessels, the stigma, and the yolk is released. If any blood vessels cross the stigma a drop of blood may spot the yolk as it is released from the follicle. 2. INFUNDIBULUM Called the infundibulum, the funnel-shaped upper end of the oviduct envelops the ovary and catches the most mature follicle as it reaches maturation and ovulates, then the yolk embarks on a 24-hour journey down the oviduct. When the yolk emerges from the follicle and moves into the upper part of the infundibulum, it's the only time in its progress when it is not covered by a layer of albumen. Fertilization, if it is to occur, will take place here. Some bacterial pathogens, such as salmonella enteritidis, are able to colonize the reproductive tracts of infected hens. If these bacteria become associated with a developing egg as it passes along the tract, and before it is surrounded by a shell, they can cause disease in a human consumer of the contaminated yolk or albumen. 3. MAGNUM The yolk spends about 15 minutes in the infundibulum before it passes into the magnum, in the magnum over a period of about three hours, it will be covered by a dense shock absorbing layer of albumen or egg white. As the albumen forms around the yolk, spiral ridges which run the length of the magnum, cause the yolk to spin like a bullet in a rifle barrel. This spinning twists the protein fibres in the albumen, just in front of, and just behind the yolk, and makes two pigtail-like structures called the chalazae. The chalazae keep the yolk suspended in the centre of the albumen and ultimately prevent it from moving around inside the egg. 4. ISTHMUS The magnum gives way to the next section of the oviduct, the isthmus, here the shell membranes are deposited. These thin layers of protein wrap loosely around the albumen covering the yolk. It is as though the yolk and its layer of albumen are a blob of jello wrapped with two sheets of cellophane. The process does not result in a smooth egg-shaped structure, in fact, an egg leaving the isthmus probably looks more like a prune than a plum. 5. SHELL GLAND The partially formed egg then enters the shell gland, here over the next 20 hours the shell will form. First, a thin albumen is secreted, this thin albumen is mostly water and it moves by osmosis through the two shell membranes into the highly concentrated thick albumen surrounding the yolk. This plumps the egg into a normal shape and stretches the shell membranes tight around it. Next, a highly concentrated solution of calcium carbonate is secreted by the shell gland and crystals of calcite form and grow on the outer shell membrane. As the crystals expand they grow into one another to form a solid shell. Very tiny spaces left in between the crystals leave pores in the shell. Lastly, a special protein solution, called the cuticle, is deposited onto the eggshell. Gas can pass through the proteinaceous cuticle and through the pores in the shell, but the two layers protect the egg from harmful bacteria. 6. VAGINA Finally, in a process called ova position the egg flips end over end. This occurs through contractions of the uterus, synchronized with relaxation of the muscular vagina, and pushes the egg out of the hen's body. 7. EGG An important part of the egg does not form until after it is laid. When an egg is laid it fills the shell, however, a hen's body temperature is 106°F and eggs are generally laid into environments that are 20 to 40 degrees cooler. As the egg cools, the inner portion contracts and forms an air cell between the two shell membranes. A chick would puncture and breathe through the air in this cell before hatching. The fully formed egg now begins another journey, if it has been fertilized it will go to a hatchery, if not, it will go to one of two places: an egg processing and packaging plant for distribution to grocery stores, or to an egg breaking plant where once processed the egg will be included in one of countless food products such as mayonnaise cake mixes or salad dressing.
