Animals that are raised for their meat are bred to be efficient in the conversion of feed into meat. Especially with the increased costs of corn and grains, it is important to carefully monitor the weight gain of the animal. Furthermore, for certain farm animals, such as pigs, it is desirable for all of the animals that are being raised in a batch to reach their targeted final weights at the same time. Specialty weighing and sorting devices have been designed by Arlyn Scales for this industry. The pig sorter consists of an inner cage with entry doors and exit doors, along with some sorting gates. The inner cage is suspended from load cells and hung from an outer cage. In normal operation, the entry door starts in the open position. An electric eye detects when an animal enters the cage. [+]
