Indigenous chicken production in South-east Asia
ABSTRACT The poultry industry of South-east Asia has two important types of production. These are: a commercial sector, characterized by its use of highly intensive units and the fact that it has developed very rapidly over the past two decades; and the traditional village-based system which has been little affected by the increasing numbers of commercial birds. The village poultry system relies on minimal resource input and, although secondary to other agricultural activities, has an important role in providing the local population with income and high quality protein. Almost every rural community keeps small flocks of indigenous chickens under a backyard type system. The sheds, when provided, are made from local materials. Whilst the birds are fed kitchen left-overs, sometimes supplemented with cheap, locally available grains, most of their time is spent scavenging. There is no breeding programme and close inbreeding occurs among the indigenous stocks. The high incidence of disease is the greatest constraint on rural poultry development.

ABSTRACT: A study was conducted on growth performance of the Lesotho indigenous chicken (LES) compared to two exotic lines, the New Hampshire (NH) and Rhode Island Red (RIR), from 3-days to 70 weeks of age, when moulting occurred. Growth traits that were under study included 3-day weight, 26-week weight, 70-week weight, average daily gain (ADG), average weekly gain (AWG) and mean feed conversion ratio (FCR). Although the mean body weight, ADG and FCR for the LES were significantly poorer than those for the NH and RIR for all traits except for the FCR and hen weight at 70 weeks of age, the LES hens compared fairly well with the exotic lines for the growth parameters considered. No significant differences were observed in hen weight at 70 weeks of age between the lines. The LES, like the NH showed potential for being a good dual-purpose breed under a semi-intensive production system, as they were able to achieve an acceptable body weight at the end of the egg laying period. However, the LES cocks recorded lower body weight gains and body weight at 70 weeks of age, compared to the exotic breeds. This contributed to the significantly lower weight gains observed in the LES line between three days and 26 weeks of age. Intensive selection in males and the implementation of a planned breeding and an adequate husbandry program could result in an improvement of the traits studied in the LES. _______________________________________________________________________________________ Keywords: Lesotho indigenous chickens, exotic lines, growth performance # Corresponding author.01/2006; 36.

ABSTRACT: Characterizing local chicken types and their mostly rural production systems is prerequisite for designing and implementing development and conservation programs. This study evaluated the management practices of small-scale chicken keepers and the phenotypic and production traits of their chickens in Oman, where conservation programs for local livestock breeds have currently started. Free-range scavenging was the dominant production system, and logistic regression analysis showed that socio-economic factors such as training in poultry keeping, household income, income from farming and gender of chicken owners influenced feeding, housing, and health care practices (p<0.05). A large variation in plumage and shank colors, comb types and other phenotypic traits within and between Omani chicken populations were observed. Male and female body weight differed (p<0.05), being 1.30.65 kg and 1.10.86 kg respectively. Flock size averaged 227.7 birds per household with 4.8 hens per cock. Clutch size was 12.32.85 and annual production 64.52.85 eggs per hen. Egg hatchability averaged 886.0% and annual chicken mortality across all age and sex categories was 161.4%. The strong involvement of women in chicken keeping makes them key stakeholders in future development and conservation programs, but the latter should be preceded by a comprehensive study of the genetic diversity of the Omani chicken populations.
