In the beef cattle diet, common roughages include hay, silage and grass. Silage is a crop that has been preserved in a moist, succulent condition by partial fermentation in a tight container (silo) above or below ground. The majority of the food cattle eat comes from this type of feedstuffs.
Birds (some dinosaurs) and mammals have a four-chambered heart. The ventricle is divided by a septum into two compartments completely separating oxygenated from deoxygenated blood and delivering the maximum amount of oxygen to the head and body at the most efficient pressure.
The heart is a four-chambered, hollow organ. It is divided into the left and right side by a muscular wall called the septum. The right and left sides of the heart are further divided into: 1  two atria-top chambers, which receive blood from the veins and. 2  two ventricles-bottom chambers, which pump blood into the arteries.he heart is a four-chambered, hollow organ.
