Resumo
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 thatof 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.(AU)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 Hillyeram 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.(AU)
