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 measures the electrical activity of a muscle. It detects any signs of blocking or slowing down of responses to nerve stimulation. The test provides information about the muscle itself and shows how well it receives stimulation from the nerve.
