The present study was planned under the project “Development and Application of Decision
Support Tools to Conserve and Sustainably Use Genetic Diversity in Indigenous Livestock
and Wild Relatives” funded by UNEP-GEF-ILRI-FAnGR (United Nations Environment
Programme-Global Environment Facility-International Livestock Research Institute-Farm
Animal Genetic Resources) to study the production systems along with phenotypic and
genetic characterization of the nine chicken populations in six randomly selected villages
within two agro-ecological zones (Site-I; sandy desert and Site-II; irrigated plains) of Punjab
province involving participatory rural appraisals, household surveys and in-depth monitoring
tools. Information collected through Participatory Rural Appraisals showed that the main
purpose of chicken keeping was home consumption and family income. Preferred chicken
breeds among moderate and poor farmers were Fayoumi (FYM), Rhode Island Red (RIR)
and Desi and were kept for egg production while Aseel (ASL) was the choice of well off and
kept for prestige or hobby. Egg production, size of egg and plumage color was the traits
preferred for FYM and RIR, broodiness, mothering ability, disease resistance and taste of
meat for Desi and Naked Neck (NNK) while aggressiveness and body stature were highly
ranked for ASL. Household surveys showed that most of the farm activities were headed by
the household head yet women were involved in all farm activities generally and in chicken
keeping particularly at both sites. More number of farmers was involved in chicken keeping
at Site-I as compared to Site-II. Semi-intensive chicken production system with free range
during day time and confined under shed at night with birds fed on household grains along
with scavenging was reported in majority of the cases throughout the year. Average prices of
birds were higher at Site-II and were highest for ASL. Health coverage was poor at both sites
with most of the farmers treating birds at the help of their own or with neighbors and friends.
There was almost absence of any formal training from any NGO or any government
department. Sources of information about chicken related issues were poor. Chicken and
eggs were marketed at farm gate, village markets or to neighbors and income obtained from
extra sale of chicken and eggs was mostly kept by women, followed by household heads. Indepth
monitoring revealed higher number of laying hens than other age classes among flocks.
The disease was major reason for exit and bird entries were mainly through household
hatched hatch and purchase. Most of the birds at both sites were multi colored or brown in
plumage with undefined feather pattern. Body weights and linear measurements were higher
for ASL and birds at Site-I than those at Site II. Genetic characterization of nine chicken
populations viz, ASL; NNK; FYM; RIR; FRR (FYM x RIR); FRA (FYM x RIR x ASL); FRU
(FYM x RIR x unknown); OLD (other local Desi) and OCB (other crossbred) using 20
microsatellite markers were found to be polymorphic. The number of alleles per locus within
chicken populations ranged from 2 to 14 with an average of 9.6 alleles per locus. Structure
and Principal Coordinate Analysis was clustered into two distinct groups with two maternal
lineages distributed among the nine populations. These results indicated that although these
nine chicken populations have already been intermixed up to some extent yet most of them
were genetically different enough to be considered as separate breeds or genetic groups. |
