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]
In a "higher welfare" system, chickens are kept indoors but with more space (around 14 to 16 birds per square metre). [39] They have a richer environment for example with natural light or straw bales that encourage foraging and perching. The chickens grow more slowly and live for up to two weeks longer than intensively farmed birds.
Halevy et al. (2000) concluded that sufficient feed directly post hatch may be critical for later muscle development. [7] A study of Noy and Sklan (1999) [8] also showed that early feeding increased body weight and breast size at marketing age in chickens and poults. They showed that early feeding reduced mortality numerically.
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 ...

Broiler breeder farms raise parent stock which produce fertilized eggs. A broiler hatching egg is never sold at stores and is not meant for human consumption. [9] The males and females are separate genetic lines or breeds, so that each line can be selected for optimal traits for productivity in either females or males, rather than a single line in which a compromise is reached between female ...
