| dc.description.abstract | Phenotypic characterization of animal genetic resources is the basis for any breed improvement program. It includes information on population size, flock size and composition, production estimates, and information on the production environment and husbandry practices which are known to play vital roles in trait expression. Breed characterization was based on phenotypic description of qualitative and quantitative traits. The study was conducted in selected districts of north-Wollo zone, Ethiopia in 2020 to phenotypically characterize and assess the breeding and husbandry practices of the indigenous goat populations. A total of 180 household heads were interviewed for the survey questionnaire data. Data for qualitative and quantitative characteristics characterization were collected from a total of 550 goats. Questionnaire and qualitative characteristics data were analyzed using SPSS, whereas, quantitative data (measurement) were analyzed using the GLM procedures of SAS. Ranking data were calculated in Microsoft Excel software. A mixed crop livestock production system was the main production system in the study area. Natural pasture, shrubs and bushes, and crop residue were the major feed resources both in dry and wet seasons with the overall mean of 37.53% and 54.26, respectively. There was a decreasing trend of communal grazing land which is due to the increasing human population, settlement, and increasing the need for cultivation areas which in turn lead to decreasing the trend of livestock population. Almost all farmers practiced natural and uncontrolled mating systems. Even if the index value is different, body conformation/appearance, coat color, and growth rate were the first, second, and third selection criteria for a breeding buck, respectively, in all agro-ecologies. While body conformation/appearance, coat color, and litter size were the first, second and third selection criteria’s for breeding does, respectively. Feed shortage, labour/manpower for keeping, drought, and predator were the major constraints for goat production in the study areas. The overall observed indigenous goat coat color patterns was | en_US |
