The scales used for measuring the weight of the domestic animals are called the live stock scales. These scales come in different sizes. Some small animals like dogs etc can be measured with the small scales. The bigger domestic animals like cow etc can be measured with big scales. The smaller ones measure in kilograms and the bigger ones measure in tons. To keep a record of the health these animals have to be weighed regularly. The veterinary doctors have these scales to measure the animals which come to them for health problems. In Zoo also the animal’s weight is regularly recorded to see into their health. The animal which stands on the weighing machine will not stand still. So the live stock scale is designed in such a way that the weight is recorded in an average manner.
