“…The results of this study are in line with those reported (Bugiwati et al, 2020a) that Gaga chickens (South Sulawesi) have more single comb types (males > 86 %), while the hens are more walnut type. Several studies of local chickens abroad reported (Agarwal et al, 2020;Bibi et al, 2021;Machete et al, 2021;Shuaibu et al, 2020;Wario et al, 2021) that the single comb type is most commonly found in local chickens. The results of this study differ from the research reported (Iskandar and Sartika, 2018) in that the pea comb type is more commonly found in male and female Agrinak chickens (> 89 %), and the rest are single types.…”

An important aspect that determines the productivity of native chickens is the genetic factor. Improving the genetic quality of chickens can be done through a breeding program which involves the selection and arrangement of mating lines. The objective of the research project is to find basic information on the ancestor's qualitative and quantitative traits to produce a new Indonesian native chicken laying-hens strain. The ancestors used as the genetic source are four native chicken lines: White, Lurik, Wareng, and Ranupane (male and female). Qualitative traits were analyzed using descriptive statistics, and quantitative data were analyzed with ANOVA of a two-level Nested Classification followed by the Least Significant Difference test. The results showed differences in plumage and shank color in each chicken line. In cocks, there were differences (P < 0.05) in body weight, wing length, tail length, head circumference, and front-body width. The height, body circumference, shank length, and beak length differed (P < 0.05) between hen lines. Qualitative characteristics (plumage and shank colors) can be used as a marker for native chicken lines. They can be used as a reference for selection according to the objectives of the breeding program. Body conformation (weight and height) can be used as selection criteria for ancestors (male and female) to produce new strains of laying native hens.

Indigenous chickens are an important Farm Animal Genetic Resource (FAnGR) in South Africa as they alleviate poverty and are a source of protein. Climate change and market demand for high-performing exotic breeds threaten and undermine locally adapted village chickens. The current study explored the risk status and signatures of adaptation of village-based indigenous chickens from two provinces and mapped their environmental suitability across the country. A total of 244 village chickens from rural areas of the Capricorn (n = 85) and Sekhukhune (n = 113) districts of Limpopo province; the Harry Gwala (n = 21) and uMzinyathi (n = 25) districts of KwaZulu-Natal province were genotyped using the Illumina 60K BeadChip. The conservation flock comprised Ovambo (OV; n = 10), Potchefstroom KoeKoek (PK; n = 20), and Venda (VD; n = 20). Naked Neck (NN; n = 20), New Hampshire (NH; n = 10), White Leghorn (WL; n = 10), and White Plymouth Rock (WR; n = 10) from the Agricultural Research Council Poultry Breeding Unit were used as reference populations and representative of flocks under conservation. The effective population size (Ne) in village chickens and conserved flocks ranged from 18 to 53 and 26 to 38 at 12 generations ago, respectively. PC1 and PC2 explained 5.64% of the total variation, which resulted in five clusters with the Venda, Naked Neck, and White Leghorn being separated from village chickens. The first three redundancy analysis (RDA) axes capture 46.8% of the total genetic variation used to detect significant outlier SNPs. A total of 386 outlier SNPs associated with all 10 environmental variables were detected. Using ecological niche modeling, chickens from Dipakakeng, Mgababa, and Podu villages, Limpopo, had a localized predicted suitability probability, while chickens originating from Nhlonga village, KwaZulu-Natal, had a broader distribution of predicted suitability habitats with elevation and BIO6 being important variables. The results of this study provide insight into the risk status, geographic suitability, and contributing environmental factors of indigenous chickens that can be used to influence conservation and improvement decisions.
