- ... A common practice for assessing livestock weight gains from grazing animals on rangelands is to confine animals overnight without feed or water to reduce variation in weight loss and percent shrink. Advances in remote sensing of vegetation, such as the Normalized Difference Vegetation Index (NDVI) provide opportunities to estimate greenness (an indicator of both the quality and quantity of the pla ...

- ... Ranching is a challenging and sometimes risky business, with cattle production (and associated enterprise income) largely being dependent on seasonal weather patterns and corresponding forage production. To help reduce this risk, the USDA–Agricultural Research Service performed a multistate study of seasonal weather effects on cattle production across the Northern Great Plains (Wyoming, North Dako ...
