The African Chicken Genetic Gains (ACGG) program is built on five “pillars of change”. The first pillar is to make available high producing tropically adapted breeds (hpTAB). The second pillar is to determine farmer-preferred hpTAB. The third pillar is to create public-private partnerships for th...

The red jungle fowl Gallus gallus is the main progenitor of domestic chicken, the commonest livestock species, outnumbering humans by an approximate ratio of six to one. The genetic control for production traits have been well studied in commercial chicken, but the selection pressures underlying ...

Indigenous chicken makes most of the world’s poultry genetic diversity particularly in developing countries. These local breeds, which are well- adapted to extensive husbandry systems and suitable for resource-poor poultry farmers endowed with very limited means, should be thoroughly studied as a...

On-farm test of chicken strains potentially adaptable to semi-scavenging production systems in Sub-Saharan Africa was undertaken in Ethiopia, Tanzania and Nigeria. Twelve (12) chicken strains were tested in 5 zones of each country in 6348 households. Kuroiler and Sasso were common to all countrie...

The African Chicken Genetic Gains (ACGG) project was started in 2014 and implemented over 5 years in Ethiopia, Tanzania, and Nigeria. The program’s vision is to increase smallholder chicken production and productivity growth as a pathway out of poverty in sub-Saharan Africa. The program was led b...

The with-in selection also known as mass-selection has been considered as the less complex approach being applied for many years in livestock species and yielded significant genetic gains. In Africa, the extent to which mass- selection applied in the genetic improvement of chicken for better perf...

Availability of appropriate genetics is important for the development of Smallholder Poultry (SHP) in Sub-Saharan Africa. The biological potential of improved dual purpose chicken strains was evaluated in Ethiopia, Tanzania and Nigeria. A total of 8 strains (Funaab Alpha, Horro, Noiler, ShikaBrow...

Economic contributions of interventions that aims to improve village chicken production through dual-purpose improved breeds-based production system was estimated using recently conducted production and marketing surveys in Ethiopia, Nigeria and Tanzania. The data were collected from sample of vi...

Summarises the critical steps for designing a comprehensive breeding system. Breed (genotype) comparison and utilization are discussed with ref. to breeding policy, environment and management systems, genetic parameters, purebreds, F1 crosses, rotational crossing, and F2 and F3 generations of bre...

Survival of indigenous goats in Kenya is at risk: due to exotic breed importation and indiscriminate crossbreeding. Phenotypic description of goats with an aim of determining their improvement, utilization and conservation is important. Phenotypic characteristics of 139 East African Goats were re...
