Body condition scoring of beef and dairy animals (1993)

Body condition scoring (BCS) of cattle allows cattle producers to assess the level of fat reserves of cows during various production phases. When regularly used, this information can be used to formulate management and feeding decisions.Reviewed September 1993 -- Extension website

Visual coherence of moving and stationary image changes

AbstractDetection thresholds were compared for moving and stationary oscillations with equivalent contrast changes. Motion was more detectable than stationary oscillation, and the difference increased with size of the feature (a Gaussian blob). Phase discriminations between a center and two flanking features were much better for motion than for stationary oscillation. Motion phase discriminations were similar to motion detection and were robust over increases in spatial separation and temporal frequency, but not so for stationary oscillations. Separate visual motion signals were positively correlated, but visual signals for stationary oscillation were negatively correlated. Evidently, motion produces visually coherent changes in image structure, but stationary contrast oscillation does not

Using NDF and ADF to balance diets (1990)

In University of Missouri Agricultural guides G3150 and G3160 we explained how detergent solutions are used to measure forage fiber. The guides show how neutral detergent solution can be used to measure neutral detergent fiber (NDF). NDF represents the total plant fiber or cell wall including hemicellulose, cellulose and lignin. These guides also show how acid detergent solution can be used to measure acid detergent fiber (ADF), which contains cellulose and lignin. Both ADF and NDF data help to more accurately estimate feed intake, energy values and animal performanceNew7/90f7M

Impacts of 40 Years of the Gudmundsen Sandhills Laboratory on Beef Cattle and Range Systems

The University of Nebraska (UNL) Gudmundsen Sandhills Laboratory (GSL) is a 12,800-acre research ranch in the Nebraska Sandhills. In 1978, Elmer “Pete” and Abbie Gudmundsen gifted the former Rafter C Ranch to the University of Nebraska Foundation. Thus, 2018 was the 40th year of UNL oversight of GSL. To the credit of UNL Administration, GSL development for range livestock research was delegated to a team of Research and Extension Specialists chaired by Dr. Don Clanton. Other members of that original team were Jim Nichols, Range Science; Gene Deutscher, Reproductive Physiologist; Dick Clark, Agricultural Economist; and Ivan Rush, Beef Extension Specialist. This team configured the ranch to investigate production and management questions pertinent to the region
