“…Meat quality traits have important economic value and are considered to be complex quantitative traits controlled by multiple genes ( Cahyadi et al, 2014 ). For example, many previous studies have shown that the fatty acid binding protein ( FABP ) gene plays an important role in improving overall meat quality ( Cho et al, 2011 ).…”

With increasing societal development and the concurrent improvement in people's quality of life, meat consumption has gradually changed from a focus on “quantity” to “quality”. Broiler production is increasingly used as a means to improve meat quality by altering various characteristics, especially its genetic factors. However, until now, little has been known about the genetic variants related to meat quality traits in Chinese purebred chicken populations. To better understand these genetic underpinnings, a total of 17 traits related to meat quality and carcass were measured in 325 Chinese Ningdu yellow chickens. We performed DNA sequencing to detect nucleotide mutations, after which we conducted association studies between PHKG1 gene polymorphisms and traits related to meat quality and carcass. Results indicated a large phenotypic variation in meat quality traits. More specifically, the single nucleotide polymorphism ( SNP ) rs15845448 was significantly associated with drip loss at 24 h ( P = 8.04 × 10 −6 ) and 48 h ( P = 5.47 × 10 −6 ), pH ( P = 2.39 × 10 −3 ), and meat color L * ( P = 9.88 × 10 −3 ). Moreover, the SNP rs15845448 reduced 24 h and 48 h drip loss by 3.62 and 5.97%, respectively. However, no significant associations were found between rs15845448 and carcass traits ( P > 0.05). Furthermore, a haplotype block containing 2 adjacent SNPs ( rs15845448 and rs15845450 ) was identified. This block displayed 4 distinct haplotypes that had significant association with drip loss at 24 h and 48 h, pH, and meat color L *. Collectively, these results provide new insights into the genetic basis of meat quality in Chinese Ningdu yellow chickens. Moreover, the significance of SNP rs15845448 could be incorporated into the selection programs involving this breed.

“…Carcass traits can be affected by genetics, feed, and environment ( Mansour and Hosna, 2010 ; Cahyadi et al., 2014 ; Arowolo et al., 2019 ). Meat quality is important for consumers and product processing and can be influenced by genetics, age, sex, feed, and management ( Fletcher, 2002 ; Frizzell et al., 2017 ).…”

This study examined the effects of plastic antipecking devices ( PAD ) on the production performance, upper beak length, behavior, and plumage condition of a local Chinese chicken breed. Three hundred sixty 63-d-old Wannan chickens with intact beaks were randomly allocated into 3 groups. Birds were fitted with the PAD at 63 d ( PAD63d ) and at 77 d of age ( PAD77d ). Control birds were not fitted with PAD. The results showed that there were no significant effects of PAD on the BW, carcass traits, and meat quality ( P > 0.05). The mortality in the PAD63d and PAD77d groups was lower than that in the control group. Compared with those in the PAD77d and control groups, the feed conversion ratio ( FCR ) from 63 to 112 d of age was lower in the PAD63d group. The ADFI of birds from 63 to 112 d of age was lowest in birds in the PAD63d group, intermediate in birds in the PAD77d group, and highest in control birds ( P < 0.05). Birds in the PAD63d and PAD77d groups showed a lower frequency of walking and running, a higher frequency of sleeping, and higher plumage scores of the back and tail than those of control birds ( P < 0.05). Birds' daily walking steps in the PAD77d group decreased compared with that of birds in the control group ( P < 0.05). The upper beak length at 91 d and 112 d of age was longest in birds in the PAD63d group and shortest in control birds ( P < 0.05). Overall, PAD appeared to be effective at reducing mortality, FCR, overall activity, and plumage damage and increasing the upper beak length.

“…Other QTL regions were also identified on GGA4 for overall body weight, CW wing weight, drum stick weight, and thigh weight ( Ikeobi et al, 2004 ; Schreiweis et al, 2005 ; Tsudzuki et al, 2007 ). Therefore, along with GGA1, GGA4 is implicated as a chromosome that harbors QTLs for growth-related traits ( Cahyadi et al, 2014 ). Regarding the QTLs for CW in KNC, two QTLs were located at 0 and 70 cM on GGA19.…”

Quantitative trait locus (QTL) is a particular region of the genome containing one or more genes associated with economically important quantitative traits. This study was conducted to identify QTL regions for body weight and growth traits in purebred Korean native chicken (KNC). F1 samples (n = 595) were genotyped using 127 microsatellite markers and 8 single nucleotide polymorphisms that covered 2,616.1 centi Morgan (cM) of map length for 26 autosomal linkage groups. Body weight traits were measured every 2 weeks from hatch to 20 weeks of age. Weight of half carcass was also collected together with growth rate. A multipoint variance component linkage approach was used to identify QTLs for the body weight traits. Two significant QTLs for growth were identified on chicken chromosome 3 (GGA3) for growth 16 to18 weeks (logarithm of the odds [LOD] = 3.24, Nominal p value = 0.0001) and GGA4 for growth 6 to 8 weeks (LOD = 2.88, Nominal p value = 0.0003). Additionally, one significant QTL and three suggestive QTLs were detected for body weight traits in KNC; significant QTL for body weight at 4 weeks (LOD = 2.52, nominal p value = 0.0007) and suggestive QTL for 8 weeks (LOD = 1.96, Nominal p value = 0.0027) were detected on GGA4; QTLs were also detected for two different body weight traits: body weight at 16 weeks on GGA3 and body weight at 18 weeks on GGA19. Additionally, two suggestive QTLs for carcass weight were detected at 0 and 70 cM on GGA19. In conclusion, the current study identified several significant and suggestive QTLs that affect growth related traits in a unique resource pedigree in purebred KNC. This information will contribute to improving the body weight traits in native chicken breeds, especially for the Asian native chicken breeds.
