“…The genetic correlation found for FI and FCR, considering the period from 35 to 41 days, were different than those found for these traits by other authors 28,33 , but similar to that found by Cruz et al 32 (0.39 ± 0.23). These differences may be due to the nature of the pleiotropic relationship between FI and FCR, which may be dependent on age.…”

Chicken feed efficiency (FE) traits are the most important economic traits in broiler production. Several studies evaluating genetic factors affecting food consumption in chickens are available. However, most of these studies identified genomic regions containing putative quantitative trait loci for each trait separately. It is still a challenge to find common gene networks related to these traits. Therefore, here, a genome-wide association study (GWAS) was conducted to explore candidate genomic regions responsible for Feed Intake (FI), Body Weight Gain (BWG) and Feed Conversion Ratio (FCR) traits and their gene networks. A total of 1430 broilers from an experimental population was genotyped with the high density Affymetrix 600K SNP array. A total of 119 associated SNPs located in 20 chromosomes were identified, where some of them were common in more than one FE trait. In addition, novel genomic regions were prospected considering the SNPs dominance effects and sex interaction, identifying putative candidate genes only when these effects were fit in the model. Relevant candidate genes such as ATRNL1, PIK3C2A, PTPRN2, SORCS3 and gga-mir-1759 were highlighted in this study helping to elucidate the genomic architecture of feed efficiency traits. These results provide new insights on the mechanisms underlying the consumption and utilization of food in chickens.

“…A medium genetic correlation (0.18) between BrW and ThW was found, with a high negative correlation (−0.52) between BrP and ThP. Similar results were reported by Cruz et al, a high correlation was found among BW, BrW, and ThW ( Cruz et al, 2020 ). Herein, we found AbFW to be genetically correlated with BW (0.13), although the relationship was close to zero between AbFP and BW (−0.06).…”

“…The heritability of body weight, average daily feed intake and average daily gain was at a medium to low level (0.21-0.44), which was similar to that of other varieties [32][33][34]. The phenotypic and genetic correlations between RFI and ADFI were 0.92 and 0.63, indicating that the heritability of ADFI and RFI was closer, which provides a reference for the subsequent breeding process [35].…”

Background Wenchang chickens are one of the most popular local chicken breeds in the Chinese chicken industry. However, the low feed conversion efficiency is the main shortcoming of this breed. Therefore, we urgently need to find a more precise breeding method to improve the feed efficiency of Wenchang chickens. In this study, we explored important candidate genes and variants for feed efficiency and growth traits by genome-wide association study (GWAS) analysis. Results Estimates of genomic heritability for growth and feed efficiency traits, including residual feed intake (RFI), average daily food intake (ADFI), average daily weight gain (ADG), body weight at 87, 95, 104, 113 days of age (BW87, BW95, BW104 and BW113), ranged from 0.05 to 0.44. Important candidate genes were screened related to feed efficiency and growth traits were screened, including PLCE1, LAP3, MED28, QDPR, LDB2 and SEL1L3 genes. Conclusion The results identified important candidate genes for feed efficiency and growth traits in Wenchang chickens and provide a theoretical basis for development of new molecular breeding technology.
