“…The mutations in the MC1R gene could affect various feather colors in Korean native chicken breeds (Nam et al, 2021). The same phenomena have been reported in Chinese native chicken breeds (Yang et al, 2019, Zhang et al, 2020, native Japanese chicken (Kabir et al, 2020), blackbone chicken (Khumpeerawat et al, 2021), and so on. Lots of nsSNPs in MC1R gene have been detected in chicken.…”

MC1R plays a crucial role in controlling the type of melanin synthesized in the melanocytes, which greatly affects plumage color in birds. One g.16796362G/T SNP was found in the MC1R gene coding region, which caused a Met120Ile mutation in the amino acid sequence. The Met120Ile mutation was located in the third transmembrane domain of the MC1R protein and decreased protein stability. The g.16796362G/T locus achieved medium polymorphism and had significant association with feather melanin content in Chinese yellow quails. The contents of total melanin and pheomelanin with AA genotype were significant lower than those with AB or BB genotypes in skin tissues, while the expression levels of MC1R mRNA had no significant difference in feathers with different genotypes. This experiment indicated that the Met120Ile mutation could affect the function of the MC1R protein and change the biosynthesis of melanin in Chinese yellow quails.

“…Thus, the meat color value is a grey area due to the black muscle. The difference in the number of melanocytes at different ages may have effects on the skin and meat color for the black-bone chicken [41]. The meat color did not differ for all groups, which may suggest that anthocyanins did not regulate related melanocyte gene expression in chickens but need more investigation to prove in further studies.…”

This study investigated the effects of dietary supplementation with different levels of purple corn pigment (PCP) on the growth performance, blood biochemical indices, meat quality, muscle amino acids, and fatty acids of growing chickens. A total of 288 (8 weeks of age) growing Chishui black-bone chickens (body weight, 940 ± 80 g; mean ± standard deviation) were randomly divided into 4 groups using a completely randomized design. The four diet groups were as follows: (1) control, basal diet; (2) treatment 1, treatment 2, and treatment 3, which were basal diet with 80, 160, and 240 mg/kg PCP, respectively. The results showed that compared with the control group, the feeding of anthocyanins significantly (p < 0.05) increased the average daily feed intake and average daily gain in chickens. Moreover, chickens receiving 80 mg/kg PCP significantly increased (p < 0.05) plasma total antioxidant capacity, superoxide dismutase, glutathione peroxidase, catalase, high-density lipoprotein cholesterol, and albumin concentrations relative to the control group. For meat quality, dietary supplementation with PCP significantly (p < 0.05) reduced the drip loss and water loss rate in breast muscle. Additionally, chickens receiving PCP tended to increase (p < 0.05) the levels of most individual amino acids, essential amino acids, and umami amino acids in the muscle. Specifically, the addition of 80 mg/kg PCP significantly improved (p < 0.05) total polyunsaturated fatty acids in chicken muscle. Accordingly, the consumption of anthocyanin-rich PCP by the growing chickens had the potential to increase the growth performance, enhance antioxidant and immune capacities, increase meat quality, and improve essential and umami amino acids as well as unsaturated fatty acids in the muscle.

“…The difference in feather color in chickens is mainly affected by the production and transformation of melanin, and MC1R plays an important role in this process ( Zhang et al, 2017 ; Khumpeerawat et al, 2021 ; Schwochow et al, 2021 ). MC1R is a highly polymorphic gene, and more than 200 variants have been found ( Zanna et al, 2021 ).…”
