CCKAR, Chicken, FCR, RFI, SNPBackground: The feed conversion ratio(FCR) and residual feed intake(RFI) are common indexes in measuring feed efficiency for livestock. RFI is a feed intake adjusted for requirements for maintenance and production so these two traits are related. Similarly, FCR is...
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. ...

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) ...
Chicken BW and feed intake (FI) were recorded each week to calculate weight gain (WG), feed conversion ratio (FCR), and production efficiency factor (PEF) = (Survival rate (%) × BW (kg))/(age (d) × FCR) × 100. When the chickens died, the FI and BW were recorded, and the ...
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...

It was proposed that ghrelin as a GH-releasing peptide may cause growth stimulation in chicken embryo and subsequent greater initial body weight for hatched chickens that is an important factor for broiler production. In past studies, administration of growth stimulatory peptides such as insulin-like...
Regression analysis indicated that the feed conversion ratio (FCR) determined for the NI birds was constant (slope not significantly different from 0) over the course of the infection (Figure 1 B). The relationship between FCR and d PI was nonlinear for the EM infected birds with an elevated...
