Abstract(s)
O principal objetivo deste estudo foi caracterizar fenotipicamente as galinhas nativas e conhecer os seus sistemas de produção nalguns municípios da província angolana do Huambo. A caracterização fenotípica implicou a avaliação de parâmetros morfológicos qualitativos e quantitativos. Os sistemas de produção foram caracterizados através da realização de inquéritos aos criadores de galinhas nativas dos municípios Huambo (distrito do Dango), Caála (comuna do Cuíma) e Longondjo (comuna do Lépi). As galinhas nativas mostraram-se morfologicamente muito heterogéneas, particularmente entre as fêmeas. Não foram encontradas diferenças morfológicas significativas entre municípios de criação. Pelo contrário, o dimorfismo sexual foi evidente. Os criadores de galinhas nativas estudadas viviam em áreas rurais, eram pobres e sem escolaridade. A criação era feita tanto por homens como por mulheres, seguindo métodos tradicionais, sem incorporação de qualquer tecnologia e sem grande intervenção humana. Nenhum deles tinha um sistema de registros da exploração. Neste estudo não foi possível avaliar a produtividade das galinhas nativas.
This document provides a literature review on native chicken production in various African countries, outlining current issues and future challenges, particularly in conservation and animal genetic improvement programs. The primary aim of this study was to phenotypically characterize native chickens and investigate their production systems in various municipalities of the Angolan province of Huambo. Phenotypic characterization includes the assessment of both qualitative and quantitative morphological parameters. The production system was evaluated by surveying native chicken breeders in three municipalities of the Huambo province: Huambo (Dango district), Caála (Cuíma commune), and Longondjo (Lépi commune). Native chickens showed considerable morphological differences, especially among females, with clear sexual dimorphism observed. The breeders, living in rural areas often facing poverty and illiteracy, practiced traditional chicken breeding methods without technology or detailed record-keeping. Both men and women participated in this activity. Native chickens were raised for both meat and eggs, serving a dual purpose. The facilities for their housing were limited or basic. Their diet consisted solely of what nature provided at different times of the year. The water they accessed came from wells. The hens were mated naturally with roosters from the village, with no intervention from the breeders. The farmers incubated the eggs to produce the next generation of birds. However, they were unable to determine the productivity of their chickens or the reasons for any illnesses or deaths among them. None of the farmers implemented a preventive health program. Both the poultry and the eggs were sold at local markets to customers from outside their villages. Selling these products was relatively easy, as they were highly desired by consumers. All the breeders indicated that the income generated from selling these products was essential for their families' well-being. Further research is needed to clarify important aspects such as the genetic characterization of native chickens raised in Huambo province and their productivity. Afterward, decisions on methodologies and programs to preserve and enhance this vital Angolan genetic and socio-cultural legacy should be made.
