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.
Many urban children experience animal husbandry for the first time at a petting farm; in Britain, some five million people a year visit a farm of some kind. This presents some risk of infection , especially if children handle animals and then fail to wash their hands ; a strain of E. coli infected 93 people who had visited a British interactive ...
Average calving interval is 391 days, and calving mortality within the first year of life is 5%. [20] Beef calves suckle an average of 5 times per day, spending some 46 minutes suckling. There is a diurnal rhythm in suckling, peaking at roughly 6am, 11:30am, and 7pm. [ 21 ]
They eat a greater variety of plants during the dry season, as fewer plants are available. While they eat grass during the wet season, they have to switch to more abundant reeds during the dry season. [11] The capybara's jaw hinge is not perpendicular; hence, it chews food by grinding back-and-forth rather than side-to-side. [12]
The Texas State Bison Herd is also a useful example of the deleterious effects of extreme population bottlenecking, with an average natality rate of 0.376 offspring per female and a 1st-year mortality rate of 52.6% from 1997 to 2002, compared to an average natality rate of 0.560 offspring per female and a 1st-year mortality rate of 4.2% for the ...

Cattle reared on a primarily forage diet are termed grass-fed or pasture-raised; meat or milk may be called "grass-fed beef" or "pasture-raised dairy". [6] The term "pasture-raised" can lead to confusion with the term "free range" which describes where the animals reside, but not what they eat.
