Book excerpt: Master's Thesis from the year 2012 in the subject Agrarian Studies, Bahir Dar University, course: animal genetics and breeding, language: English, abstract: ABSTRACT Phenotypic characterization of indigenous chicken ecotypes was conducted in North Wollo from January 2011 to May 2012 with the objectives of characterizing indigenous chicken and their production system. Simultaneously, identification of development intervention for improved utilization of chicken genetic resources was also identified. In the first part of data collection, one focused group discussion per agro-ecological zones was held. Then, administration of well-structured questionnaire and morphometric measurement were employed. Measured quantitative traits of chicken among the three altitudes were analyzed by linear model of SAS 2002 for male and female chickens separately. Subsequently, mean value of each traits were compared using Tukey’s mean comparison method. Multivariate analysis of principal component analysis, canonical discriminant, step-wise discriminant and clustering analysis was performed by SPSS 19.0 for male and female chicken ecotype separately. Nechi (17.6%), Tikur (12.6%) and Key (10.8%) plumage colour were found dominantly all over the study area. Findings of the focus group discussion revealed that there were morphologically differences among chickens of high altitude, mid altitude and low altitude study areas. Similarly, findings from the semi-structured questioner revealed that indigenous chicken ecotypes are dual-purpose. The critical constraints of scavenging chicken production were disease (60.13%) predators (20.59%) and feed shortage (19.28%). Number of egg lay/clutch (37.91%) and plumage colour (37.58%) were the major preferred trait by the farmers in the study area. For qualitative and quantitative study, 715 sample chickens were recorded by category of agro-ecology. Linear measurements on six traits were taken from 210 mature male and 305 mature female chickens. The overall mean body weight of indigenous male and female chickens was 1500.97gm and 1253.36gm respectively. The overall age at sexual maturity for male and female was 24.25 ± 0.04 and 23.84 ± 0.05 weeks respectively. There was highly significant difference (p

This book was released on 2015-11-30 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the important roles of local chickens, rearing them can be considered as a side line agricultural activity. However, the indigenous chicken populations have been neglected by conservation and development programs. Instead high input demanding exotic commercial chicken breeds are introduced and supported by the government to increase poultry productivity.The most dominant chicken types reared in Ethiopia are local ecotypes, which show a large variation in body conformation, plumage color, comb type and productivity.

This book was released on 2015-03-31 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poultry production is the most dynamic sector that signified the rapid growth of all meat sectors during the last decades (FAO, 2010). The global growth of poultry industry reflects an increase of world meat demand and consumption (de Haan et al., 2001; Delego, 2003; Delgado et al., 2008; Narrod et al., 2008; Trostle and Seeley, 2013; FAO 2014). Among the poultry species, chickens are the humankind’s most common and widespread birds. Chicken meat represents 88% of poultry meat output (Global Poultry Trends, 2014). Although the demand of chicken products has increased tremendously due to not only the fast growth of world population but also the increase of per capita global consumption of meat, nearly one third of chicken breeds are reported to be at risk of extinction (Pym, 2010). This is alarming and thereby calls for an assessment of the existing genetic resources, because many of the varieties which are at risk may have traits that can be valuable in future environmental challenges and marketing demands. Genetic variability in chickens is the best insurance for the adaptation and sustainable production for the future unpredictable needs (Simianer and Meyer, 2003). One of the important elements concerning sustainable use of animal genetic resources is to ensure that locally adapted populations remain a functional part of production systems.

Book excerpt: Master's Thesis from the year 2017 in the subject Agrarian Studies, language: English, abstract: The study was conducted in Jimma zone of three Agro-ecology in six-selected farmer's kebele starting from March to June 2017 with the aim to phenotypic ally characterize selected indigenous chicken, identify poultry management and breeding practices in three agro-ecologies of Jimma Zone. A survey was carried out on 180 randomly selected respondent as well as 555 heads of native chickens, (445 females and 105 males) for qualitative and quantitative trait measurements. In Ethiopia, the agricultural sector is a corner stone of the economic and social life of the people. The livestock sector in Ethiopia contributes 12% and 33% of the total and agricultural Gross Domestic Product (GDP), respectively, and provides livelihood for 65% of the population. The sector also accounts for 12-15% of the total export earnings. These livestock genetic resources are important or vital to development of the economic, social and environmental of the one country. The diverse agro-ecology and agronomic practice prevailing in the country together with the huge population of livestock in general and poultry in particular, could be a promising attribute to boost up the sector and increase its contribution to the total agricultural output as well as to improve the living standards of the poor livestock keepers. Poultry production, as one segment of livestock production, has a peculiar privilege to contribute to the sector. This is mainly due to their small size and fast reproduction compared to most other livestock and its well fitness with the concept of small-scale agricultural development. Moreover, it goes eco-friendly and does not compete for scarce land rest.The majority of indigenous chickens in the tropics are maintained under village chicken production systems. These production systems are typically characterized by low input and low output systems, mainly in terms of egg and meat p

This book was released on 2019-08-15 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The poultry sector continues to grow and industrialize in many parts of the world. An increasing human population, greater purchasing power and urbanization have been strong drivers of growth. A clear division is developing between industrialized production systems of large and medium size feeding into integrated value chains, and extensive production systems supporting livelihoods and supplying local or niche markets. The primary role of the former is to supply cheap and safe food to populations often distant from the source of supply, while the latter acts as a livelihood safety net, often as part of a diverse portfolio of income sources. Understanding how poultry production systems and value chains work is essential in order to develop a country’s poultry sector sustainably. This review for Ethiopia is part of a series of Livestock Country Reviews developed by FAO's Animal Production and Health Division (AGA). The reviews aim to support sustainable and effective development interventions and policy recommendations and contribute to informed decision-making and investments in the poultry sector by: (i) providing information and data about national poultry supply chains (with a special focus on poultry production); (ii) analysing strengths, weaknesses and prospects along the supply chain; and (iii) identifying opportunities for poultry sector development.

Download or read book Village Chicken Production Systems in Rural Africa written by Aichi J. Kitalyi and published by Food & Agriculture Org.. This book was released on 1998 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The poultry production systems of Africa are mainly based on the scavenging indigenous chickens found in virtually all villages and households in rural Africa. These systems are characterized by low output per bird. Nevertheless, over 70 percent of the poultry products and 20 percent of animal protein intake in most African countries come from this sector. Therefore, increased rural poultry production would result in a positive impact on household food security both in increased dietary intake and in income generation. ... This study coincided with the World Food Summit, held at FAO, Rome, from 13 to 17 November 1996, where delegations committed their governments and civil society to a global attack on food insecurity and poverty. Poultry, like other short-cycle animal stock, is viewed by the FAO Special Programme for Food Security (SPFS) as a crucial element in the struggle for sustained food production and poverty alleviation. The guidelines provided in this study are particularly pertinent to those countries participating in the SPFS where village chicken production will have a substantial impact on increased household food security and gender equity."--Foreword.
