Application of Gisfor Biodiversity Conservation of Indigenous Chickens in Ile-Ife, Nigeria
Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2018, Vol 11, Issue 12
Abstract
Reports of various authors indicate that there is a decline in the number of the Yoruba ecotype indigenous chicken, found in southwestern Nigeria. The geographical distribution of these strains of chicken is poorly documented thereby hampering the implementation of any effective management and sustainable conservation program. Hence this study conducted an open survey among breeders of local fowls in Ile-Ife, a traditional town in southwestern Nigeria to identify some of the attractive characteristics of these chickens that can be included in breeding programs designed for biodiversity conservation of indigenous chickens. Ile-Ife, located on latitudes 7.52°N – 7.57°N and longitudes 4.50°E – 4.57°E, was classified into three zones of core, transition and sub-urban using high resolution satellite imagery. Snowball sampling technique was used to administer questionnaire to breeders of indigenous chickens in all the three zones of Ile-Ife. The GPS coordinates of all the sampled locations were also recorded. The data from the questionnaires were analyzed, within a geographic information system (GIS), for trait preferences, selection and the risk status of the strains that exists among the population of indigenous chicken in Ile-Ife. The study observed that the size of cock and the egg production performance of the hen were the most preferred traits. The comb type of the cock and the plumage colour of the hen were also preferred. The ratings for these traits in the three zones showed heterogeneity. The study also analyzed the selection practice by the chicken breeders to regulate the size of the flocks. The result of this analysis revealed that selection was made to increase the normal feather chickens. However, selection practice did not favor the naked neck, frizzle feather and the short-flight chickens. This was attributable to the cultural significance attached to these strains of chickens. This ignorant action of the breeders of indigenous chickens had facilitated the decline in the number of these strains.A survey on the availability of the different strains revealed that the normal feather chicken constituted 91.7% of the indigenous chickens in the study area. Other strains were available in minute quantities. The frizzle feather and the short-flight feather chickens each represented2.9% while the naked neck chickens were 2.3% of the available stock. The results of this study highlighted the need to breed local fowls, not just to eat as meat, but for the sustainable conservation of the different strains that exist within the Yoruba ecotype chicken. This is to prevent the extinction of these strains.
