Studienarbeit aus dem Jahr 2020 im Fachbereich Agrarwissenschaften, , Sprache: Deutsch, Abstract: This review is done on comparative evaluation of production and reproduction performances and constraints of local and exotic layer chicken in Ethiopia. Poultry is by far the largest group of livestock species in the world and chicken largely dominate flock composition. In Ethiopia; except chickens other poultry species production is not practicing that they are living in their natural habitat. The poultry sector in Ethiopia can be characterized into three major production systems based on some selected parameters such as breed, flock size, housing, feed, health, technology and bio-security. These are large commercial or intensive, small scale commercial or semi-intensive and free range or village back yard poultry production system. However, the majority of chicken production system in Ethiopia remains as village or back scavenging system which consist the indigenous chickens as major. In Ethiopia, poultry industry plays a significant role in the supply of human food (eggs and meat) in rural and urban area and as a source of income, especially to small holder farmers. Mean number of egg production was higher for exotic breed than local chicken ecotypes. Higher egg production and better reproductive life span is obtained from exotic chickens than local ones. Moreover, overall survival rate of exotic and crossbred chickens are found comparable to local chicken. Therefore, introducing Bovans Brown chickens having better productive and reproductive performance is important to enhance productivity. Non-genetic factors should also be considered to improve the performance of existing local chicken population. But, feed shortage, disease and other critical gaps that need to be filled by the institutions of research and development to improve the productive performance of exotic chicken breed in Ethiopia.
"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.
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.
This publication is part of a series which seeks to raise awareness amongst policymakers and agricultural support services in low and middle income countries about sustainable income generation opportunities for small-scale farmers and local communities. It contains guidance on the keeping of poultry, and topics discussed include: the history of domestic poultry production, its contribution to sustainable rural livelihoods, key components of rural poultry production, diversification and intensification issues, utilisation of poultry products. It includes examples of case studies of poultry production schemes in Bangladesh, South Africa, Guatemala, Cambodia and the Philippines.
Commercial Chicken Meat and Egg Production is the 5th edition of a highly successful book first authored by Dr. Mack O. North in 1972, updated in 1978 and 1984. The 4th edition was co-authored with Donald D. Bell in 1990. The book has achieved international success as a reference for students and commercial poultry and egg producers in every major poultry producing country in the world. The 5th edition is essential reading for students preparing to enter the poultry industry, for owners and managers of existing poultry companies and for scientists who need a major source of scientifically based material on poultry management. In earlier editions, the authors emphasized the chicken and its management. The 5th edition, with the emphasis shifted to the commercial business of managing poultry, contains over 75% new material. The contributions of 14 new authors make this new edition the most comprehensive such book available. Since extensive references are made to the international aspects of poultry management, all data are presented in both the Imperial and Metric form. Over 300 tables and 250 photos and figures support 62 chapters of text. New areas include processing of poultry and eggs with thorough discussions of food safety and further processing. The business of maintaining poultry is discussed in chapters on economics, model production firms, the use of computers, and record keeping. Updated topics include: breeders and hatchery operations; broiler and layer flock management; replacement programs and management of replacements; nutrition; and flock health. New chapters address flock behavior, ventilation, waste management, egg quality and egg breakage. Other new features include a list of more than 400 references and a Master List of the tables, figures, manufacturers of equipment and supplies, research institutions, books and periodicals, breeders, and trade associations. Commercial growers will find the tables of data of particular interest; scientists will be able to utilize the extensive references and to relate their areas of interest to the commercial industry's applications; and students will find that the division of the book into 11 distinct sections, with multiple chapters in each, will make the text especially useful.
This book gives an overview of the poultry industry in the warm regions of the world and covers research on breeding for heat resistance. And highlights some of the findings on nutrient requirements of chickens and turkeys.
Seminar paper from the year 2018 in the subject Agrarian Studies, language: English, abstract: This review paper highlights on chicken production in Ethiopia with emphasis on meat production and the aim of delivering summarized information for the beneficiaries and reader. Poultry production is increasing globally due to an increased population number and an increased demand of poultry products. Poultry production plays a great role for the supply of egg and meat from rural and urban area as a source of small holder family income and poultry production is synonymous with chicken production under the present Ethiopian conditions. In Ethiopia, poultry production systems show a clear distinction between the traditional, low input system on the one hand and modern production system using relatively advanced technology on the other hand. Poultry production is very important by supplying nutritional need of humans, alleviating poverty, requiring small space and capital for investment; sources of family income and benefit to female and children and a lot of socio economic and cultural benefit and affected by different factors shortage an high cost of feed; disease and biosecurity and environmental constraints. Due to different constraints the meat production capacity of local or indigenous chicken is low; so it is difficult to supply the meat need humans by using indigenous breed because indigenous breeds are dual purpose with low production capacity and should be genetically upgraded by selecting superior birds and cross breeding with indigenous breeds to cope the low production capacity of indigenous breeds of chickens.
"This guide provides information and advice to those concerned with the production and sale of eggs in developing countries with an emphasis on marketing, i.e. producing in order to meet market demand. Market-led egg production enables long-term business survival, higher profits and a better standard of living for the egg producer."--FAO
