Demonstration and performance evaluation of dual purpose chicken “Potchefstroom Koekoek” under agro pastoral management condition at Asayta districts of Afar regional state in Ethiopia

Dual purpose poultry package demonstration was undertaken at Awsi resu zone, Asayta district, Korodora kebele agro pastoral association with the objectives of demonstrating and evaluating the performance of chicken under agro pastoral management condition. Agro pastoral association and participant were selected purposively from the district, on the basis of experience and willingness to construct poultry house and cover all the associated package costs. A total of ten households were selected based on the package requirements. Training was given on poultry house & housing, health care, feeds & feeding systems. Finally one hundred eighty (180) Koekoek of two month old chicks (18 chicks to each agro pastoral) were distributed with two month feeding and medication materials at the agro pastorals gate. The average survival rates of chicken up to 24 weeks of age were 98.3%. But after 24 weeks of age later the total number of chicken declined to 93.3%. The average survivability rates of the chicken per household at 52 weeks of age were 91.7 %. Chicken mortality rate were observed 1.7% in the fi rst 24weeks of age but after 24 weeks of age later the rate had increased to 6.7%, That could be due to the onset of the hot season, difference in management and feeding condition. The average weight at 20 weeks of age under agro pastoral management condition was 2.23kg and 1.91kg for male and females respectively. The average egg weight at initial laying stage (5% production stage) was observed 39.4g while the average weight (49.7g) recorded at pick stage.The average egg production performance of the breed in the study area was 182 eggs per year. The variable costs and income earned the average income generated per individual agro pastorals were 8987.00 birr.

Chicken are the most important avian species for the resource challenged families of the developing world, because they are sources of income and animal protein, and can be raised in varying agro climates with limited resources, feed and housing [5]. In sub Saharan Africa, 85% of all households keep chicken under free range system, with women owning 70% of it; providing cheap/affordable animal protein in the form of meat and eggs as well as being a reliable source of cash income [6]. Besides the sector signifi cantly constitutes to human livelihood and food security of poor households and can be considered an initiative enterprise owing to its low cost [6].
In Ethiopia, like other African countries, attempts have been made at various times by the Ministry of Agriculture and Rural Development (MOARD) and several other institutions including research, higher learning institutions and NGOs to improve village poultry production systems through introduction of exotic breeds and fertile eggs [7]. Distribution of a day-old and 2 months old improved chicken breeds, has been some of the livestock extension packages implemented by the ministry of agriculture.

Objectives
To demonstrate and evaluate the performance of the chicken under agro pastoral condition To promote and disseminate the approved full-fl edged poultry packages to the users To build the skill of participant community of the study area on chicken production.
To aware the contribution of poultry technologies to household income and food security

Description of the study area
The study was conducted at Asayta district ( Figure 1) (Awsi resu) of the Afar national regional state. The research was conducted under agro pastoral household management condition at Korodora kebele. The target kebele's (Korodora) was located 10 km far from the town of Asyata district. The target kebele and participants were selected in consultation with the respected districts administration and Pastoral agriculture development offi ces.

Climate
Asyta districts is climatically characterized as largely arid and some of semi-arid agro-ecological area, where livestock production is the main occupation of the community. The average temperature of the area is about 32 o C while during the hot season (May, June, July, August and September) the temperature reaches 42 o C and the rainfall is bimodal with erratic distribution, with the long rainy season (Kerma) between Mid-June to Mid-September and short rainy season (Sugum) occurs between March and April, and the average annual rainfall is between 200 and 250 mm [8].
The altitude range of the area is between 400-420 m [8] and most of the rangeland of the study area falls under below 450 m above sea level. The dominate soil types in these areas are vertisols, sandy, and deposits of silt and fi ne sand particles occur in the plain fl at areas where cultivation is practiced [8].
In most of the study area, the topography is lowland plains.

Farming system
The study area of Asayta districts consisted of 13 kebeles of these 2 were in the city, 6 were pastoralist entirely dependent on livestock production and the remaining 5 were agropastoralists practicing both crop production and extensive livestock rearing.

Design of the experiment
The study was conducted to demonstrate and evaluate performance of Potchefstroom koekoek chichen under agro pastoral management system. For this study, ten female house headed were selected on the bases of previous experience in poultry rearing, willingness to construct or modify poultry house. Training was given on all management aspects and data to be collected. Accordingly, 8 weeks age of 15 pullet and 3 cock koekoek chicken along with other inputs (housing materials, feeder, drinker, and medicaments) were given per households.
Technical backup, data collection, monitoring and evaluation were under taken by researcher and wereda's developmental agents (DAs) in a regular base. Data was collected from day of chick's delivery up to start of the fi rst egg lay and continued until 52 week of age.

Disease prevention and control
The health follow up were undertaken using the respected

Feeds and feeding system
A balanced ration provided from Kaliti animal feed factory was fed to the chicken in the fi rst 20 weeks of age. Prior to end of this commercial balanced ration, the agro pastorals were getting started feeds preparation from locally available crops like maize, sorghum, salt and home food refusals. In this study the average amount of supplemental feed used were recorded 80gm/day/chicken. Browsing improved forages (grasses and legumes) in the backyard and scavenging home wasted was the major means of satisfying their nutrient requirements.

Data analysis
Descriptive statistic such as mean and percentage were used to summarize the data (mean egg production, weight gain and profi t earned compared) using Microsoft Excel.

Results and discussion
Dual purpose Koekoek breed technology package demonstration and evaluation were properly employed in the target kebele. The data revealed that, the average survival rates of chicken up to 24 weeks of age were 98.3% but after 24 weeks of age later the total number of chicken declined to 93.3%.
This mortality and predator attacked could be due to difference in management from household to household (especially for predator attacked in some households); poor management and feeding condition were the main reason for dropped of chickens. This result is slightly lower than that of Araka area (20.2%) southern Ethiopia [9]. Status of chickens and cause of mortality on the distributed chicken presented in table 1.
The average survivability rates of the chicken per household at 52 weeks of age were 91.7 %, which presented in Figure 2 and Table 2. The reason might be the developments of managerial skill of the participants and the adaptability of the chickens were increased from time to time. In some households hatching were started with using local breed this indicated that, the breeds were well adapted to the area and the managerial skill of the participants were increased.
Chicken mortality rate were observed 1.7% in the fi rst 24weeks of age but after 24 weeks of age later the rate had increased to 6.7%, That could be due to the onset of the hot season, difference in management and feeding condition were the main reasons for dropped of chickens. Mortality rate at different age of weeks (  [9]. Similarly this result was higher as compare to reports of Aman et al., [9], (1.04kg and 1.01kg for male and

Egg weight
The average egg weight at initial laying stage (5% production stage) was observed 39.4g. This is almost similar to the weight achieved at Araka area (40.2gm) [9]. As indicated in table 5, the increases in egg weight were observed as the production stage increases from 5% to pick stage (49.7gm). The average weight (49.7g) recorded at pick stage in this study was slightly similar to DZARC (51.9g) under intensive production system.

Egg production
The average egg production performance of the breed in the study area was 182 eggs per year. This is production yield were similar to [10], in East Showa zone, Lume distric under farmers management condition who reported 187.04±13.49. While the average age of fi rst lying in the study area was recorded 24.5 weeks. This result also similar to Ada"a district under farmers management condition which was reported 5.3 months age at fi rst egg laying for the same breed. Production performance and average age of fi rst laying presented in table 6 [11,12].

Partial budget analysis
In calculating the partial budget analysis includes all variable costs, change in net income and change in net profi t.
In this study feed, medication and chicken cost were considered as variable costs whereas the sale of eggs and the existing chicken/egg also used as an income source. In this study the

Conclusion and Recommendation
The result of the current demonstration showed a good
