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.
An internal wall of tissue divides the right and left sides of your heart. This wall is called the septum. The area of the septum that divides the atria is called the atrial or interatrial septum. The area of the septum that divides the ventricles is called the ventricular or interventricular septum.
