ASSESSMENT OF PRODUCTION SYSTEM, EGG QUALITY AND CARCASS CHARACTERISTICS OF VILLAGE CHICKEN IN BENCH MAJI ZONE, SOUTH WESTERN ETHIOPIA

Abstract

The study was conducted in three districts of Bench Maji Zone in Southern Ethiopia with the objective of assessing the production system, egg quality traits and carcass characteristics of indigenous chicken. A total of 270 households were selected by multi-stage purposive random sampling technique and interviewed using semi-structured questionnaires. A total of 450 eggs and 45 adult male chickens were also purchased to evaluate the egg quality traits and carcass characteristics, respectively. The results revealed that the flock size per household was 10.4 with cock to hen ratio of 1:2.9. Scavenging with occasional supplementation was the major feeding system (80.7%). Maize (91.1%), sorghum, Taro and Kocho were the types of supplementary feeds used in their order of importance. Seasonal disease outbreak and predation were the most challenges of village chicken productivity. The average age of cockerel at first mating and pullet at first egg laying was 5.9 and 6.4 months, respectively. The average number of eggs per clutch and the annual egg number of local chicken in the study area were 14.8 and 54.6, respectively. The mean number of eggs incubated by local hen was 11.8 with 82.2% hatchability and 48.8% survivability of hatched chicks. The purpose of rearing chicken and the egg produced was primarily for selling as a source of cash income followed by hatching and home consumption. The average egg weight and shape index of local chickens was 43.9 g and 72.7%, respectively. The average shell thickness of local chickens was about 0.33 mm. The respective average albumen height and the HU score was 3.4 mm and 61.2. The average yolk height and yolk color were 14 mm and 10.9, respectively. The average slaughter weight of local male chicken was about 1449 g. The edible carcass yield was 966 with 66.7% dressing. The proportions of breast meat, thigh, drumstick and wing were 25.4%, 19.5%, 15.4% and 10.2%, respectively. The study revealed variations in different production traits which might be due to management difference and genetic dissimilarities of local chicken ecotypes in the studied districts. Further research is recommended to evaluate their performance potentials under improved feeding and management systems
