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

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

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2017 in the subject Veterinary medicine, language: English, abstract: Indigenous village chicken is the most prominent class of livestock in the country and constitutes about 60-80% of the total poultry population, their productivity is low because of poor nutrition and low genetic potential. The number of flock per household in most Ethiopian communities is small constituting on average of 7-10 mature chickens 20-24 adult hens, a male birds and a number of growers of varies ages. Such production system may result in slow growth and poor layers of small sized eggs. About 40-60% of the chicks hatched die during the first 8 weeks of age mainly due to disease and predators attack. About half of the eggs produced have to be hatched to replace chicken that have died and the brooding time of the laying hens is longer, with many brooding cycles required to compensate for its unsuccessful brooding. Pullets and cockerels reached sexual maturity at an average age of 6.4 months and 5.7 months, respectively. Even though the productivity of local chicken is very poor, they are very important to withstand certain harsh environmental conditions, and can perform better under poor management than cross and exotic breeds, they are also well known to possess desirable characters such as ideal mother, good sister, hatch their own eggs, excellent foragers, resistance to common poultry disease and special meat and egg quality.

Available in PDF, EPUB and Kindle. Book excerpt: Cyclin Dependent Kinase 5 provides a comprehensive and up-to-date collection of reviews on the discovery, signaling mechanisms and functions of Cdk5, as well as the potential implication of Cdk5 in the treatment of neurodegenerative diseases. Since the identification of this unique member of the Cdk family, Cdk5 has emerged as one of the most important signal transduction mediators in the development, maintenance and fine-tuning of neuronal functions and networking. Further studies have revealed that Cdk5 is also associated with the regulation of neuronal survival during both developmental stages and in neurodegenerative diseases. These observations indicate that precise control of Cdk5 is essential for the regulation of neuronal survival. The pivotal role Cdk5 appears to play in both the regulation of neuronal survival and synaptic functions thus raises the interesting possibility that Cdk5 inhibitors may serve as therapeutic treatment for a number of neurodegenerative diseases.
