1. Eating and Digestion:
* Rumination: Cows are ruminants, meaning they have a four-chamber stomach that allows them to digest cellulose (plant material) efficiently.
* Rumen: The largest chamber, where bacteria and other microorganisms break down the food.
* Reticulum: This chamber filters out large particles and pushes food back to the mouth for further chewing (called rumination).
* Omasum: This chamber absorbs water and nutrients.
* Abomasum: This is the true stomach where enzymes break down food further.
2. Elimination:
* Feces: After passing through the stomach, the remaining indigestible material forms feces.
* Solid Waste: Cow dung is primarily composed of undigested plant material, bacteria, and other microorganisms.
* Liquid Waste: Cows also produce urine, which is a liquid waste product containing excess water, salts, and nitrogenous compounds.
3. Excretion:
* Rectum: Feces are stored in the rectum and expelled through the anus.
* Urinary Bladder: Urine is stored in the bladder and expelled through the urethra.
Key Points:
* Manure: Cow dung, also known as manure, is a valuable fertilizer.
* Waste Management: Proper waste management is crucial on dairy farms to prevent environmental contamination and odor problems.
* Health Indicators: Changes in the frequency, consistency, or color of cow manure can indicate health problems.
