The principal field corn varieties are dent corn, flint corn, flour corn (also known as soft corn) which includes blue corn (Zea mays amylacea), [1] and waxy corn. [2] Field corn primarily grown for livestock feed and ethanol production is allowed to mature fully before being shelled off the cob and being stored in silos, pits, bins, or grain ...
Livestock could be fed by grazing on grasslands, integrated or non-integrated with crop production. Livestock produced in stalls or feedlots are landless and are typically fed by processed feed containing veterinary drugs, growth hormones, feed additives, or nutraceuticals to improve production. Similarly, livestock consume grains as the main ...
The oldest type of sweet corn contains more sugar and less starch than field corn intended for livestock. Tends to be heartier in respect to planting depth, germination and growth than other types. Begins conversion of sugar to starch after peak maturity or harvest, and as such is best eaten immediately after harvest.
Most of the corn grown in the United States today is yellow dent corn or a closely related variety derived from it. [2] Dent corn is the variety used in food manufacturing as the base ingredient for cornmeal flour (used in the baking of cornbread), corn chips, tortillas, and taco shells. It is also used to make corn syrup.
Waxy corn or glutinous corn is a type of field corn characterized by its sticky texture when cooked as a result of larger amounts of amylopectin. The corn was first described from a specimen from China in 1909.
Cattle production worldwide is differentiated by animal genetics and feeding methods, resulting in differing quality types. Cattle are basically residual claimants to crop or land resources. Those countries with excess or low-value land tend to grass-feed their cattle herds, while those countries with excess feed grains, such as the U.S. and ...
The production of corn (Zea mays mays, also known as "maize") plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of ...
Livestock production systems can be defined based on feed source, as grassland-based, mixed, and landless. [149] As of 2010, 30% of Earth's ice- and water-free area was used for producing livestock, with the sector employing approximately 1.3 billion people. Between the 1960s and the 2000s, there was a significant increase in livestock ...
