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 2013 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution and density of birds vary from place to place. Local chickens, which are not properly characterized, have been found to vary widely in body size conformation, plumage colour and other phenotypic characteristics (Mogesse, 2007). The productivity of indigenous birds under the rural production systems has been reported to be very low (Teketel, 1986). This low productivity may be attributed to lack of improved poultry breeds, the presence of predators, the incidence of chicken diseases, poor feeding and management factors(Alemu, 1995; Alemu and Tadelle, 1997). Hence, the FAO of the United Nations has proposed an integrated programme for the global management of genetic resources on an international level. This is being developed by FAO, with the main objective of assisting countries by providing extensive searchable databases and guidelines for better characterization, utilization and conservation of animal genetic resources. Accordingly, this study sought to unearth the variation among local chickens in other part of the country in terms of feather distribution and structure, the presence of genes responsible for such variation and other morphological features.

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 Molecular Diagnostics Promises and Possibilities written by Mousumi Debnath and published by Springer Science & Business Media. This book was released on 2010-01-29 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rapid development in diverse areas of molecular biology and genetic engineering resulted in emergence of variety of tools. These tools are not only applicable to basic researches being carried out world over, but also exploited for precise detection of abnormal conditions in plants, animals and human body. Although a basic researcher is well versed with few techniques used by him/her in the laboratory, they may not be well acquainted with methodologies, which can be used to work out some of their own research problems. The picture is more blurred when the molecular diagnostic tools are to be used by physicians, scientists and technicians working in diagnostic laboratories in hospitals, industry and academic institutions. Since many of them are not trained in basics of these methods, they come across several gray areas in understanding of these tools. The accurate application of molecular diagnostic tools demands in depth understanding of the methodology for precise detection of the abnormal condition of living body. To meet the requirements of a good book on molecular diagnostics of students, physicians, scientists working in agricultural, veterinary, medical and pharmaceutical sciences, it needs to expose the reader lucidly to: Give basic science behind commonly used tools in diagnostics Expose the readers to detailed applications of these tools and Make them aware the availability of such diagnostic tools The book will attract additional audience of pathologists, medical microbiologists, pharmaceutical sciences, agricultural scientists and veterinary doctors if the following topics are incorporated at appropriate places in Unit II or separately as a part of Unit-III in the book. Molecular diagnosis of diseases in agricultural crops Molecular diagnosis of veterinary diseases. Molecular epidemiology, which helps to differentiate various epidemic strains and sources of disease outbreaks. Even in different units of the same hospital, the infections could be by different strains of the same species and the information becomes valuable for infection control strategies. Drug resistance is a growing problem for bacterial, fungal and parasitic microbes and the molecular biology tools can help to detect the drug resistance genes without the cultivation and in vitro sensitivity testing. Molecular diagnostics offers faster help in the selection of the proper antibiotic for the treatment of tuberculosis, which is a major problem of the in the developing world. The conventional culture and drug sensitivity testing of tuberculosis bacilli is laborious and time consuming, whereas molecular diagnosis offers rapid drug resistant gene detection even from direct clinical samples. The same approach for HIV, malaria and many more diseases needs to be considered. Molecular diagnostics in the detection of diseases during foetal life is an upcoming area in the foetal medicine in case of genetic abnormalities and infectious like TORCH complex etc. The book will be equally useful to students, scientists and professionals working in the field of molecular diagnostics.
