Diseases can be avoided with proper maintenance of the feed and feeder. A feeder is the device that supplies the feed to the poultry. [8] For privately raised chickens, or chickens as pets, feed can be delivered through jar, trough or tube feeders. The use of poultry feed can also be supplemented with food found through foraging. [9]
The feed mix will be adjusted to meet nutritional needs at each stage. Feed might be restricted to control body weight, for example with "skip a day" feeding, or feeding 5 days out of 7. A vaccination program is carried out, which ensures the longevity of the parent stock, and the immunity may be passed to the broiler progeny.

In the U.S., the average feed conversion ratio (FCR) of a broiler was 1.91 kilograms of feed per kilograms of liveweight in 2011, an improvement from 4.70 in 1925. [18] Canada has a typical FCR of 1.72. [19] New Zealand commercial broiler farms have recorded the world's best broiler chicken FCR at 1.38. [20]
Poultry feed can include roxarsone or nitarsone, arsenical antimicrobial drugs that also promote growth. Roxarsone was used as a broiler starter by about 70% of the broiler growers between 1995 and 2000. [75] The drugs have generated controversy because it contains arsenic, which is highly toxic to humans. This arsenic could be transmitted ...
Selection for fast early growth-rate, and feeding and management procedures to support such growth, have led to various welfare problems in modern broiler strains. [1] Welfare of broilers is of particular concern given the large number of individuals that are produced; for example, the U.S. in 2011 produced approximately 9 billion broiler chickens.
Smithfield Foods hog CAFO, Unionville, Missouri, 2013. In animal husbandry, a concentrated animal feeding operation (CAFO), as defined by the United States Department of Agriculture (USDA), is an intensive animal feeding operation (AFO) in which over 1,000 animal units are confined for over 45 days a year.
In poultry farming, early feeding is the ad lib availability of feed and water for day-old chicks from the moment of hatching from the egg.. Early feeding has a positive effect on chick performance because development and maturation of important organs is not retarded post hatch, but continues.
