The fast growth of the Cobb 500 is associated with an increased rate of various health problems. Compared to slower-growing chickens, they have a higher rate of sudden death syndrome, [12] hock burns, [13] Tibial dyschondroplasia, [14] weaker disease resistance and antibody response, [15] bone deformations, and problems with walking.
As of 2011 in the US, broiler chickens has an FCR of 1.6 based on body weight gain, and mature in 39 days. [25] At around the same time the FCR based on weight gain for broilers in Brazil was 1.8. [25] The global average in 2013 is around 2.0 for weight gain (live weight) and 2.8 for slaughtered meat (carcass weight). [26]
Modern commercial broilers, for example, Cornish crosses and Cornish-Rocks, [citation needed] are artificially selected and bred for large-scale, efficient meat production. They are noted for having very fast growth rates, a high feed conversion ratio, and low levels of activity. Modern commercial broilers are bred to reach a slaughter-weight ...
Growing puppies require higher levels of protein than adult dogs of the same breed to promote proper growth and development. [29] Protein should account for at least 25% of energy; however protein requirements also depend on the digestibility of the protein and age of the puppy. [ 29 ]
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 ...
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 ...
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.
In the first week of a broiler's life, it can grow up to 300 percent of its body size. A nine-week-old broiler averages over 9 pounds (4 kg) in body weight. At nine weeks, a hen will average around 7 pounds (3.2 kg) and a rooster will weigh around 12 pounds (5.5 kg), having a nine-pound (4 kg) average. Broilers are not raised in cages.
