Swine
Live weight of swine can be estimated by measuring the body length (from the back of the head to the tail head) and the heart girth of the animal with a tape measure. Using the table below, an approximate weight can be calculated. For example, if the body length is 130 cm and the heart girth 110 cm, the swine weighs about 105 kg.
