Study Notes
Reticulum in Beef Cattle
- The reticulum acts as a filter, separating solid food particles from liquids, and preventing solid objects from entering the intestines.
Omasum in Beef Cattle
- The omasum's main function is to absorb water and nutrients from the digesta, acting as a water-absorbing organ.
Saliva in Ruminal Fermentation
- Saliva provides buffer agents, such as bicarbonate, to help maintain a stable pH in the rumen, enabling optimal microbial fermentation.
- Saliva also contains enzymes that break down starches, aiding in carbohydrate digestion.
Abomasum in Beef Cattle
- In the abomasum, gastric enzymes and acids break down the digesta, mixing it with stomach acids and enzymes to further digest proteins and fats.
Rumination in Beef Cattle
- Rumination, or 'chewing cud', allows cattle to regurgitate and re-chew previously consumed food, increasing the surface area for digestion and improving nutrient extraction.
- Rumination aids in the mechanical breakdown of cellulose, making it more accessible to microbial fermentation.
