In the present study, we used an F2 chicken population in a genome-wide association study (GWAS) to detect potential genetic variants and candidate genes associated with daily feed intake (FI) and feed efficiency, including residual feed intake (RFI) and feed conversion ratio (FCR). Methods: ...
Although it sounds esoteric, the feed conversion rate is at the heart of raising a sustainable chicken. Also known as the feed to meat ratio, this number is simply the pounds of feed given to a chicken divided by the weight of the cleaned carcass. ...
ChickenFeed efficiencyPolymorphismsGHRLGHSRIGF1RThe ghrelin ( GHRL ), ghrelin receptor ( GHSR ), and insulin-like growth factor 1 receptor ( IGF1R ) genes have crucial effects on body weight (BW), body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) in many ...
Feed conversion ratio (FCR) was determined by dividing the amount of feed consumed in each period by the amount of weight gained, on a pen basis. Bird mortality was 2.2% for the duration of the study. Table 1. Starter, grower, and finisher diet compositions. Empty CellComposition (%1) ...

The SAA is a major acute-phase protein of the chicken, and is produced predominantly by the liver as a systemic manifestation of the body’s response to inflammation (Eckersall, 2000). The very low concentration of SAA was in agreement with Chamanza et al. (1999) and showed that no ...
Wannan Yellow chicken was selected as experiment material. It is a famous native chicken breed and popular in the southeast of China for its delicious meat and unique flavor. There is considerable variation in feed efficiency between commercial broilers and native chickens. In addition to extrinsic...
Poultry, especially chicken, is one of the most widely consumed meats globally. The demand for poultry products, such as meat and eggs, is consistently high due to factors like affordability, versatility, and nutritional value. Nutritional value is a significant driver of the demand for poultry ...
