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

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.

This book was released on 2013-01-09 with total page 105 pages. Available in PDF, EPUB and Kindle. 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

Download or read book Diatoms written by F. E. Round and published by Cambridge University Press. This book was released on 2007-12-04 with total page 1208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a wide-ranging introduction to the diatoms together with an illustrated description of over 250 genera. Diatoms are important as perhaps the commonest group of autotrophic plants on earth and are abundant in all waters and on soils and moist surfaces. The introduction describes the diatom cell in detail, the structure of the wall (often extremely beautiful in design), the cell contents and aspects of life cycle and cell division. The generic atlas section is the first account of diatom systematics since 1928 (Karsten in Engler and Prantl: Die Nauturlichen Pflanzenfamilien) and each generic description is accompanied by scanning electron micrographs to show the characteristic structure. Most of the latter have been prepared specially for this work from the authors' own collections. The Diatoms will be the standard reference work on the group for years to come and is an essential reference volume.

This book was released on 2013-06-29 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 25 years have witnessed a revolution in the way ecologists and evolutionary biologists approach their disciplines. Modern molecular techniques are now reshaping the spectrum of questions that can be addressed while studying the mechanisms and consequences of the ecology and evolution of living organisms. "Molecular Ecology and Evolution: Approaches and Applications" describes, from a molecular perspective, several methodological and technical approaches used in the fields of ecology, evolution, population biology, molecular systematics, conservation genetics, and development. Modern techniques are introduced, and older, more classic ones refined. The advantages, limitations, and potentials of each are discussed in detail, and thereby illustrate the widening range of cross-field research and applications which this modern technology is stimulating. This book will serve as an important textbook for graduate and advanced undergraduate students, and as a key reference work for researchers
Download or read book DNA Fingerprinting State of the Science written by Sergio D. Pena and published by Springer Science & Business Media. This book was released on 1993-07-01 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA fingerprinting had a well-defined birthday. In the March 7, 1985 issue of Nature, Alec Jeffreys and coworkers described the first develop ment ofmu1tilocus probes capable of simultaneously revealing hypervari ability at many loci in the human genome and called the procedure DNA fingerprinting. It was a royal birth in the best British tradition. In a few months the emerging technique had permitted the denouement of hith erto insoluble immigration and paternity disputes and was already heralded as a major revolution in forensic sciences. In the next year (October, 1986) DNA fingerprinting made a dramatic entree in criminal investigations with the Enderby murder case, whose story eventually was turned into a best-selling book ("The Blooding" by Joseph Wambaugh). Today DNA typing systems are routinely used in public and commercial forensic laboratories in at least 25 different countries and have replaced conventional protein markers as the methods of choice for solving paternity disputes and criminal cases. Moreover, DNA fingerprinting has emerged as a new domain of intense scientific activity, with myriad applications in just about every imaginable territory of life sciences. The Second International Conference on DNA Fingerprinting, which was held in Belo Horizonte, Brazil in November of 1992, was a clear proof of this.
