Chicken were possibly domesticated in South and Southeast Asia. They occur ubiquitously in East Africa where they show extensive phenotypic diversity. They appeared in the region relatively late, with the first undisputed evidence of domestic chicken in Sudan, around not, vert, similar 700 BC. We...

The experiment was done at estate management unit in Sebele, Gaborne. Ten 23 weeks old laying Tswana chickens were bought from a local farmer and divided into two groups of five each, using complete randomised design. Group one was fed on layer mash and the other group was fed on composite local ...

Understanding the complex origin of domesticated populations is of vital importance for understanding, preserving and exploiting breed genetic diversity. Here, we aim to assess Asian contributions to European traditional breeds and western commercial chickens for mitochondrial genetic diversity. ...


Dana, N.Megens, H.-J.Crooijmans, R.P.M.A.Hanotte, Olivier H.Mwacharo, Joram M.Groenen, M.A.M.Arendonk, Johan A.M. van[East Asian contributions to Dutch traditional and western commercial chickens inferred from mtDNA analysis]East Asian contributions to Dutch traditional and western commercial chickens inferred from mtDNA analysis

This study describes the variations in the physical features and the useful attributes of different populations of indigenous chickens. Five populations of chickens in different regions of Ethiopia were studied based on 13 qualitative traits recorded for a total of 1 125 chickens. Additional meas...

1. White leghorns at the Central Poultry Farm averaged egg production than 50% white Leghorn x Baladi crosses (148 to 132 eggs) under controlled test conditions for a 10 month period in the year 1958/59, but the latter survived slightly better (52% as compared to 65%). 2. White Leghorns lived and...

This study was carried out to investigate the productivity and the natural disease resistance potential of free-ranging local chickens in Tanzania. A total of 84 adult free-ranging local chicken ecotypes were studied, namely: Mbeya, Morogoro-medium, Ching’wekwe, Kuchi and Singamagazi. Adult body ...

In the tropics, a large number of smallholder farms contribute significantly to food security by raising pigs and poultry for domestic consumption and for sale on local markets. The high cost and, sometimes, the lack of availability of commercial protein supplements is one of the main limitations...

Poultry are important for many poor households in developing countries, but there are many constraints to poultry production, including disease. One of the most important diseases of chickens is Newcastle disease (ND). Even though there are effective vaccines against this disease available in mos...
