Abstract

Abstract. Yaemkong S, Tuan NN. 2019. Diversity of phenotypic characteristics of White Tailed-Yellow Chicken populations reared under free-range system in Phitsanulok Province, Thailand. Biodiversitas 20: 1264-1273. The objective of this study was to evaluate phenotypic diversity of White tail-yellow chickens in Mueang District, Phitsanulok, Thailand. A total of 200 male chickens from the purposive samples were collected, and then analyzed by using descriptive statistics, correlation and least squares mean for subclasses of each factor. The results showed that the phenotypic of White tail-yellow Chickens had the highest white-yellow beak (60.29%), hin comb (65.50%), golden-yellow neck plumage (95.69%), back plumage (96.17%) and wing plumage (67.94%), white-black long curving tails (70.11%), black back tails (71.14%) and white-yellow shank (59.81%) for qualitative traits. The quantitative traits such as body weight, body height, body length, body width, wing length, shank length, and toes length were 2.78±0.58 kg, 61.95±3.77 cm, 24.93±1.66 cm, 16.62±1.91 cm, 41.85±2.52 cm, 12.72±0.77 cm, and 8.39±0.66 cm, respectively. The highest positive correlation was recorded between neck plumage and back plumage (r=0.70; p<0.01). Moreover, body weight was the highest correlation with wing length (0.58; p<0.01) whereas body length was the highest positive correlation with wing plumage (0.21; p<0.01). However, beak and comb had no significant effect on all traits (p>0.05) except for neck, back and wing plumage, long curving tail, back tail and shank color (p<0.05).

Indigenous Lien Minh chicken of Vietnam: Phenotypic characteristics and single nucleotide polymorphisms of GH, IGFBP and PIT candidate genes related to growth traits

“…The observed results of neck plumage color were in agreement with those of Amnueysit et al (2000), the author reported that the neck and wing plumage color had a few mixing from other colors such as red, black, and whiteyellow color. Back-plumage color and wing plumage color results were also similar to the result of Suphawadee et al (2019). A study of Daikwo et al (2011) on the Dekina hen native chicken breed found that hens with brown plumage accounted for the highest percentage (41.8%) of the chicken population surveyed.…”

Discriminant Canonical Tool for Differential Biometric Characterization of Multivariety Endangered Hen Breeds

“…Previous studies have reported that phaneroptic features are somehow correlated in native chicken breeds, provided they may derive from the expression of the same gene background across the body parts [ 40 ]. Additionally, it has been suggested that these qualitative traits have significant effects on other quantitative traits such as body weight and daily gain in chicken [ 40 , 41 ].…”

Qualitative and quantitative phenotype of Kai Tor-Kai Tang (Gallus gallus) in the lower-northern region of Thailand

“…Data were collected for a total of 100 adult male KT chickens from 35 farmers. The data for the phenotypical characteristics of KT chickens in the lower-northern region were described through field observations, direct measurements, and photography (Yaemkong and Ngoc 2019), and animal genetic resources under field conditions for qualitative and quantitative traits following FAO standard descriptors (FAO 2012). The qualitative phenotypical characteristics included the comb type, earlobe color, color around the eyes, beak color, neck plumage color, back plumage color, wing plumage color, long curving tail color, back tail color, shank color, spur type, and scale type (Figure 2).…”

“…Compared to other types of Thai native chickens, an understanding of the current state of the qualitative and quantitative phenotype of the KT chicken is very minimal due to the low impact on commercialization. There is a lot of literature reporting the diversity of the phenotypic characteristics of indigenous chicken breeds in Thailand, such as the White Tailed-Yellow chicken (Yaemkong and Ngoc 2016;Yaemkong and Ngoc 2019), the Khiew-Phalee chicken (Phromnoi et al 2022), the Black-bone chicken (Buranawit et al 2016), and other breeds of native chicken in Thailand (Akaboot et al 2012;Laenoi et al 2015;Maw et al 2015). However, chicken identification has been done mainly on the phenotype, both qualitatively and quantitatively (Ismoyowati and Susanto 2012).…”
