The Cobb 500 is a fast-growing broiler chicken breed. They can reach a 2 kg slaughter weight at 33 days old. [1] [2] They make up around half of all globally farmed chickens as of 2016. [3] The Cobb 500 is controversial due to their health problems. Animal rights and animal welfare groups such as Open Cages have called for the industry to stop ...
The quantity of feed, and the nutritional requirements of the feed, depend on the weight and age of the poultry, their rate of growth, their rate of egg production, the weather (cold or wet weather causes higher energy expenditure), and the amount of nutrition the poultry obtain from foraging. This results in a wide variety of feed formulations.
Breed broiler is any chicken (Gallus gallus domesticus) that is bred and raised specifically for meat production. [1] Most commercial broilers reach slaughter weight between four [2] and six weeks of age, although slower growing breeds reach slaughter weight at approximately 14 weeks of age. Typical broilers have white feathers and yellowish skin.
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 ...
This is due to genetic selection and nutritional modifications (but not the use of growth hormones, which are illegal for use in poultry in the US [38] and many other countries, and have no effect). Once a meat consumed only occasionally, the common availability and lower cost has made chicken a common meat product within developed nations.
One indication of the effect of broilers' rapid growth rate on welfare is a comparison of the usual mortality rate for standard broiler chickens (1% per week) with that for slower-growing broiler chickens (0.25% per week) and with young laying hens (0.14% per week); the mortality rate of the fast-growing broilers is seven times the rate of ...
Organic poultry production requires organic management in nutrition, preventative health care, living conditions, handling/processing, and record keeping. [22] The Soil Association standards [ 23 ] used to certify organic flocks in the UK indicate a maximum outdoors stocking density of 1,000 birds per hectare and a maximum of 2,000 hens in each ...
