Automatic cattle sorting

ECM combines multiple objective measurements on each individual. They include weight, ultrasound for internal tissue characteristics like back fat thickness, and video imaging for external dimensions, along with a science-based projection model, to sort finished cattle into a uniform marketing group. “This approach extends to the packing plant as well, with automated live and carcass identification transfer and matching,” Jackson says. “We have enjoyed a surprisingly good track record at matching the correct carcass and feed-yard performance data back to the animal's ranch ID.”

Accurate data
The Calan Broadbent Feeding System provides individual electronic recognition and feed security that is used worldwide, says Douglas Briggs, a spokesman for Calan. In the program, which is used for university research and smaller feeding programs and dairies, each animal wears an electronic sensor key around its neck. The key activates a feed door. The animal pushes open the door and feeds.

“The narrow feed barrier opening prevents other animals from stealing its ration,” Briggs says. “It's one door, one key, one animal and one ration. The system provides absolute animal security [accurate feed intake data].”
