The cattle cycle is the approximately 10-year period in which the number of U.S. beef cattle is alternatively expanded and reduced over several consecutive years in response to perceived changes in profitability by producers.

The mixer plays a vital role in the feed production process, with efficient mixing being the key to good feed production. If feed is not mixed properly, ingredients and nutrients will not be properly distributed when it comes time to extrude and pelletize the feed, or if the feed is to be used as mash. This means that not only would the feed ...
The adjacent western provinces and northern US states are similar, so the use of corn as cattle feed has been limited at these northern latitudes. As a result, few cattle are raised on corn as a feed. The majority are raised on grass and finished on cold-tolerant grains such as barley. [61] This has become a marketing feature of the beef. [9]

The regular feed conversion ratio, i.e. output fish mass divided by total feed mass. The conversion ratio only taking into account the fish-based component of fish feed, called the FIFO ratio (or Fish In – Fish Out ratio). FIFO is fish in (the mass of harvested fish used to feed farmed fish) divided by fish out (mass of the resulting farmed ...
Intensive animal farming, industrial livestock production, and macro-farms, [1] also known as factory farming, [2] is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. [3]
In 1997, in response to outbreaks of Bovine spongiform encephalopathy, commonly known as mad cow disease, the United States and Canada banned a range of animal tissues from cattle feed. Feed bans in United States (2009) Canada (2007) expanded on this, prohibiting the use of potentially infectious tissue in all animal and pet food and fertilizers.
