    “Feed makes up one of the biggest expenses in grazing a cow-calf herd, so keeping track of the amount of feed being fed each day is crucial to the bottom line. This was a fact recognized in 1989 when GSL was using a scale on its haystack mover, so researchers knew exactly how much hay was being fed. The same fact drives new technology today, such as the Smart Feeder being tested at GSL last summer.”

The Gudmundsen Sandhills Laboratory (GSL) is a research ranch located in the heart of the Nebraska Sandhills. It is comprised of 11,600 acres of upland native range and 1,200 acres of sub-irrigated meadow. It was gifted to the University of Nebraska Foundation in 1978.
Since GSL’s inception, research and educational programs have become more ecologically diverse and team oriented. Joint projects with animal, range, soil, veterinary, economics, entomology, geology, hydrology, forestry and wildlife have increased our understanding of the Sandhill's ecosystem. This has resulted in advances in range livestock nutrition, beef cattle reproduction, grazing systems, rangeland ecology, low cost cattle management, groundwater issues, and wildlife management.
