The aim with this work was to evaluate a progeny selection strategy that considers not only the progenies means, but also the mean from the population from which the progeny came. It uses several inbreeding generations information in order to mitigate the interaction effect. |

The aim of this study was to gain understanding of local chicken farming system from the Western Highlands of Cameroonian. Interviews and structure questionnaire were applied to 156 household.
The main results showed that local chickens are bred by all the tribes in the area. Chicken farming is practiced by 58.3% of women, aged 30 to 50 years (51.3%) who provide 100% of the manpower. Farmers are from all religions, literacy level is relatively high (74.4%) although about 91% of farmers have never been trained in poultry farming, and 14.7% of them have been rearing local chickens for more than 20 years. Local chicken rearing has multiple purposes in 84.6% of farmers (self-consumption, markets, gift and savings). Local chickens farming contribute annually by more than 100.000F CFA to household income. Chicken farming is associated with small ruminants (26.3%), cattle (3.8%), pigs (3.2%) and other animal species (43.1%; dog, cat, commercial chicken broilers, ducks, rabbits guinea pigs). Farmers identified four main genetic types of local chicken, namely normal feathered chickens (98%), crested chickens (44%), naked-neck chickens (26.9%), feathered tarsus chickens (22 %) and frizzle chickens (4.5%). The size of the flocks varied from 7 to 70 with an average of 16 chickens per farm. The structure consists of 8.85% cocks, 23.35% adult hens, 22.1% growers and 45.6%chicks. Chickens were generally raised under free-range and extensive system (96.1%). They were kept overnight in kitchens (50.6%), locally made poultry houses (16.7%), huts (12.2%), abandoned houses (4.5%) while 16% of chickens slept on trees. Kitchen waste (98.7%), free scavenging (96.8%) and cereals (76.9%) were the main sources of feed. The average number of eggs produced in a year varied from 38 to 45 with a hatching rate of 79.6%. The main challenges in chicken farming were diseases (51.9%), predation (48.7%), financial issues for inputs acquisition and lack of equipment (44.2%), feed (41.02%), housing (33.9%), lack of improved genetic material (30.8%) and stock theft were the main constraints. Despite these challenges, most of local poultry farmers were planning to increase their flock size, improve housing, and acquire improved genetic material. This study suggest that more technical support to local chicken farmers could booster the productivity.
