<b>An ex situ study on body characteristics and effect of plumage color on body weight of indigenous chicken (<i>Gallus domesticus</i>) in Bangladesh</b>

Abstract

ABSTRACT. The study was conducted at the Bangladesh Livestock Research Institute (BLRI), Savar, Dhaka, Bangladesh with the objectives of comparing the body characteristics and body weight of three Indigenous chicken genotypes namely Common Desi, Hilly and Naked Neck. Of the four hundred and eighty nine birds analyzed the proportion of Common Desi, Naked Neck and Hilly chicken were 49.49, 24.95 and 25.56% respectively. The most predominant plumage color was reddish black (33.13%). Four types of shank colors were most frequently observed, i.e. white (39.87%), yellow (37.22%), black (20.04%) and mixed (2.87%). The earlobes were mainly reddish white (44.79%) followed by white (29.24%) and red (25.97%). The most predominant skin color was white (92.22%). Most birds had a single comb (96.12%). Hilly birds were heavier than the other Indigenous chicken groups (p < 0.05). The mature weight between Common Desi and Naked Neck did not differ significantly (p > 0.05) but significantly differed from that of Hilly chicken. In terms of shank length and circumference, there were no significant (p > 0.05) differences between Common Desi and Naked Neck chicken, but Hilly chicken had significant (p < 0.05) differences from both.Keywords: indigenous chicken, morphological characteristics, body weight.Investigação ex situ sobre as características do corpo e os efeitos da cor das penas no peso corporal de frangos indígenas (Gallus domesticus) em Bangladesh RESUMO. O estudo foi conduzido no Instituto de Pesquisa Animal (BLRI) em Savar, Dhaka, Bangladesh, para comparar as características corporais e o peso corporal de três genótipos de frangos indígenas, Common Desi, Hilly e Naked Neck. A proporção dos genótipos Common Desi, Naked Neck e Hilly foi respectivamente 49,49, 24,95 e 25,56% num total de 489 aves analisadas. A cor predominante das penas foi preto avermelhado com 33.13%. Foram observados os quarto tipos de cores mais frequentes das pernas: branca (39,87%), amarela (37,22%), preta (20,04%) e mista (2,87%). A cor das orelhas era geralmente branca avermelhada (44,79%), seguida por branca (29,24%) e vermelha (25,97%). A cor da pele mais predominante era branca (92,22%). A maioria das aves tinha uma só cresta (96,12%). As aves Hilly eram mais pesadas do que os outros grupos de aves indígenas (p < 0,05). Não havia diferença significativa entre o peso maduro entre as aves Common Desi e Naked Neck (p > 0,05), mas havia diferença significativa do peso das aves Hilly. Em termos de cumprimento de perna e circunferência, não havia diferença significativa (p > 0,05) entre Common Desi e Naked Neck, embora as aves Hilly diferissem significativamente (p < 0,05) dos outros dois.Palavras-chave: aves indígenas, características morfológicas, peso corporal.

Diversity of phenotypic characteristics of White Tailed-Yellow Chicken populations reared under free range system in Phitsanulok Province, Thailand

“…And red wing plumage color had the highest body length (25.40 ± 0.99 cm), followed by orange color (24.71 ± 0.45 cm) and golden-yellow color (24.11 ± 0.46 cm). These results were similar with Tabassum et al (2014) who reported that plumage colors did not affect body weight, back length, body circumference, and pelvis width significantly but Sarker et al (2014) found significant effect of plumage color on body weight of Indigenous chicken in Bangladesh. Moreover, several investigators who found significant effect of plumage colors on back length and body circumference in Senegalese chicken (Apuno et al 2011) and also found significant effect of specific plumage colors and age groups (p<0.05 and p<0.01, respectively) on egg production (Shahjahan et al 2011) Long curving tail color had significant effect on body weight, body height, body width, wing length and toe length (p<0.05), except for body length and shank length (p>0.05).…”

Phenotypic and Morphometric characterization of indigenous chickens at Jhenaigati upazila of Sherpur district in Bangladesh

“…On the other hand bird types (full feathered, naked neck and cap headed indigenous chicken) had no significant effect (p>0.05) on eggs per clutch (Shahjahan, 2010). However, among three types of indigenous chickens in present study, Naked Neck had comparatively lower body weight, back length, body circumference and pelvis width than Non-descript Deshi and Cap headed chicken and this findings was in line with the research work of Sarker et al (2014).…”

“…Plumage colors did not affect body weight, back length, body circumference and pelvis width significantly but Sarker et al (2014) found significant effect of plumage color on body weight of Indigenous chicken in Bangladesh. On the other hand, Apuno et al (2011) found significant effect of plumage colors on back length and body circumference in Senegalese chicken.…”

Body Conformation, Morphometry Indices and Inheritance Pattern of Indigenous Dwarf Chickens of Bangladesh

“…Chest girth of IDM and IDF were 3.53-9.51% and 2.20-5.71% reduced than their NSC counterparts in the present investigation. Sarker et al (2014) have stated that the average chest girth of indigenous chicken was 29.98 cm at 30 weeks of age which was much closer to the current study.…”
