Grazing is an agricultural term to describe the natural behavior of cattle moving across pastures and rangelands as they consume different plants. Surprisingly, grazing cattle are selective about where and which plants they will eat, and land managers consider grazing distribution an essential factor in deciding how to manage their herds, including how to prevent overgrazing for conserving biodiversity of the land.

Agricultural Research Service (ARS) scientists are developing an innovative approach to address a major environmental challenge facing the nation's animal farmers: the accumulation of nutrients in the manure.
Manure produced in livestock and poultry operations has been increasing since the 1950s when large-scale feeding operations, along with large-scale crop farms, began to replace many of the nation's small, family-run farms that traditionally produced both crops and livestock and used the manure as fertilizer to boost crop yields.

Calves are young and vulnerable animals. In a short period, calves have to develop from a monogastric into a ruminant animal. This transition requires them to grow in both size and mass, while dealing with transportation, man handling and changing environments. All these challenges together cause a lot of stress that may lead to a lower immune system.

Maximizing efficiency and minimizing environmental impact
In a drive towards sustainable solutions, PANCOSMA, ADM’s global feed additives business, have developed a range of XTRACT® bioactive products to address methane emissions of livestock ruminants. According to FAO 2013*, these emissions represent 5% of all greenhouse gases released into the atmosphere.

Predicting grassland productivity is a major challenge for ranchers and other land managers with grazing livestock. This productivity is key each spring when they are trying to decide how many cattle to turn out to pasture, how long to graze an area, or where forage might be abundant.

An Agricultural Research Service (ARS)-led team has completed a comprehensive life-cycle analysis quantifying the resource use and various environmental emissions of beef cattle production in the United States. The aim is to establish baseline measures that the U.S. beef industry can use to explore ways of reducing its environmental footprint and improve sustainability.

Using high-tech tools, Agricultural Research Service (ARS) scientists and their cooperators have taken a deep dive into the microbial "soup" of the cow's rumen, the first of four stomach chambers where tough plant fibers are turned into nutrients and energy.
Ultimately, such efforts could lead to new ways of ensuring the health and wellbeing of cows as well as improving their production of milk, meat and other products, noted Derek Bickhart, a research microbiologist with ARS' U.S. Dairy Forage Research Center in Madison, Wisconsin.

Despite a successful program to eliminate cattle fever ticks during the first half of the 20th century, these ticks still manage to cross the Mexican border into Texas. A new vaccine developed by Agricultural Research Service (ARS) scientists with the U.S. Department of Agriculture (USDA) could control these pests and help prevent a reinfestation of cattle fever ticks in the United States. These ticks can transmit pathogens that cause bovine babesiosis and anaplasmosis—diseases that can kill cattle.
