Hybrids (a combination of breeds) are bred for either meat or egg production and the latter such as âBovan Goldlineâ (the type of hens used in most battery systems) can lay up to 320 eggs per year.
Electrocardiogram records the electrical activity of your heart. An EKG (or electrocardiogram) is an electrical representation of the cardiac activity as detected by surface electrodes placed in specific locations across the chest and extremities. These electrodes detect the electrical activity occurring in the heart and these are depicted as deflections of a line.
An electromyogram (EMG) is a test that is used to record the electrical activity of muscles. When muscles are active, they produce an electrical current. This current is usually proportional to the level of the muscle activity.n EMG is often performed when patients have unexplained muscle weakness. The EMG helps to distinguish between muscle conditions in which the problem begins in the muscle and muscle weakness due to nerve disorders.
