Broilers are usually kept at high stocking densities. [14] This can reduce feed intake and growth. [2] Management conditions (litter quality, temperature and humidity) are however more important than stocking density. [23] Many broilers die during the processes of catching, packing and transport. [14]
A FCR (kg feed dry matter intake per kg live mass gain) for lambs is often in the range of about 4 to 5 on high-concentrate rations, [19] [20] [21] 5 to 6 on some forages of good quality, [22] and more than 6 on feeds of lesser quality. [23]
Broiler chicks. The broiler industry is the process by which broiler chickens are reared and prepared for meat consumption. Worldwide, in 2005 production was 71,851,000 tonnes. From 1985 to 2005, the broiler industry grew by 158%. [1] A key measure of performance is the feed conversion ratio (FCR), the
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.
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.

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.
Animal feed is food given to domestic animals, especially livestock, in the course of animal husbandry. There are two basic types: fodder and forage. Used alone, the word feed more often refers to fodder. Animal feed is an important input to animal agriculture, and is frequently the
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 ...
