Abstract The study was conducted in Charuhurit kebele in Menit Shasha woreda West Omo Zone, south west region (SWR) Ethiopia. Before the commencement of the study need assessment was done on existing livestock production system and their constraints through conducting group discussion with pastoralists, then the pastoralists were prioritized poultry production system as major problem need immediate intervention. A pastoralist and agro-pastoralist extension research group (PAPREG) which containing 25 pastoralists were established and randomly assigned to different production system (10 intensive productions, 10 semi intensive and five extensive production system). 125 pullets of Bovan Brown chicken breed age 75 days purchased from Bushoftu Alema farm were distributed and before distribution training on housing, feeding, health and overall handling system of animals were given for pastoralists. The study revealed that high mortality rate or low survivability rate was observed before the onset egg production in the study area. There were no significant differences in age of animals before onset of egg lying, but number of egg produced every month was significantly (p < 0.05) higher between production systems. The average age at onset of egg lying was 22.10 weeks. The result shown that significantly (p < 0.05) higher number (23.77) of eggs per month per hen was recorded for intensive production system. Finally, the authors concluded that Bovan Brown chicken breed under village production in terms of their egg production performance were feasible in the study area to enhance family nutrition and income generations.

Introducon Ethiopia is one of the African countries which have pastoralist, agro pastoralist and agronomists in the rural areas (85% of the total population). Most of the livelihoods’ of rural community survive through agriculture practices. Chicken are widespread and almost every rural family owns chickens, which provide a valuable source of both family The Scientific Temper (2023) Vol. 14 (3): 799-805 E-ISSN: 2231-6396, ISSN: 0976-8653 Doi: 10.58414/SCIENTIFICTEMPER.2023.14.3.36 https://scientifictemper.com/ protein and income (Tadelle et al., 2003). The total chicken population in the country is estimated to be 57 million with native chicken type representing 78.85%, hybrid chicken 12.02% and exotic breed 9.11 (CSA, 2021). The most dominant chicken types reared in Ethiopia are local ecotype, which show a large variation in body position, plumage color, comb type and productivity (Halima, 2007). However, the economic contribution of the sector is not still proportional to the huge chicken numbers, attributed to the presence of many productions, reproduction and infrastructure constraints (Halima, 2007; Fikadu, 2021). The chicken production system in Ethiopia can be characterized by not market oriented, low input, scavenging and traditional management system consisting of local breed (Afras, 2018). The indigenous birds are small in body size and low producers of meat and egg. The egg production potential of local chicken is 30 to 60 eggs/year/hen with an average of 38 g egg weight under village management conditions, while exotic breeds produce around 250 eggs/ year/hen with around 60 g egg weight in Ethiopia (Yizengaw et al., 2022).The total chicken egg and meat production in Ethiopia is estimated to be about 78,000 and 72,300 metric tons, respectively (Buli, 2017).
