Dairy cattle grazing in Germany. In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming.
Grazing behaviour is a type of feeding strategy within the ecology of a species. Specific grazing strategies include graminivory (eating grasses); coprophagy (producing part-digested pellets which are reingested); pseudoruminant (having a multi-chambered stomach but not chewing the cud); and grazing on plants other than grass, such as on marine ...
Ruminating animals have various physiological features that enable them to survive in nature. One feature of ruminants is their continuously growing teeth. During grazing, the silica content in forage causes abrasion of the teeth. This is compensated for by continuous tooth growth throughout the ruminant's life, as opposed to humans or other ...
A bison mother and calf grazing on the prairie. Today, cattle, pronghorn and white-tailed deer are the most abundant mammals on the shortgrass prairie. Domestic cattle were placed in the prairie and have essentially replaced the native species that used to live in the shortgrass prairie such as bison and elk.
Browsing is a type of herbivory in which a herbivore (or, more narrowly defined, a folivore) feeds on leaves, soft shoots, or fruits of high-growing, generally woody plants such as shrubs. [1] This is contrasted with grazing , usually associated with animals feeding on grass or other lower vegetations.
Yellowstone National Park was established in 1872, when market hunting of all large grazing animals was rampant. Not until after 1886, when the United States Army was called in to protect the park and wildlife slaughter was brought under control, did the large animals increase in number. [ 12 ]
The harsh terrain and climate of hill farms are hard on the animals, causing them to be relatively very unproductive. [4] Because of this, hill farming can have economic strains on the farmers who generally have low income. [4] Wet weather, as often experienced in the uplands, create additional animal feed costs for farmers. [9]
Rangelands account for an estimated 70% of the earth's landmass; thus, many cultures including those of the United States are indebted to the economics that the world's grasslands have to offer, from producing grazing animals, tourism, ecosystems services such as clean water and air, and energy extraction.
