Book Description
"The need to preserve farm animal diversity is increasingly urgent, says the author of this definitive book on endangered breeds of livestock and poultry. Farmyard animals may hold critical keys for our survival, Jan Dohner warns, and with each extinction, genetic traits of potentially vital importance to our agricultural future or to medical progress are forever lost."--BOOK JACKET.

Book Description
There are more poultry breeds than most individuals realise and for anyone considering or preparing to get involved in the raising and breeding of poultry, it is vital to understand as much as possible about as many of them as possible. With more than 500 breeds recognised by the American Poultry Association, there are different feed necessities, housing requirements, incubation times, egg information, and costs of raising just about any of these various breeds. This book provides the details that every potential poultry breed needs to start creating detailed plans for purchasing, raising, and breeding their new small farm animals. You will learn about each of the 500+ different breeds of poultry, from chickens to turkeys and ducks. Each breed will be laid out with complete details about everything you need to know to raise them effectively. From how to breed that particular breed to how to raise the chicks, you will be able to breed and gather eggs from chickens and breed for meat the ducks and turkeys you select. You will learn exactly which breeds are best for egg production by volume and quality and which ones are best for meat by taste and quality. You will learn the dietary needs of each breed and what they require from you to stay alive in all four seasons as well. Poultry and small farming experts were interviewed for this book to provide detailed insight into how poultry is selected and raised and throughout the book you will find small bits of information about how each breed is different from the rest, what suggestions are offered for raising that particular breed and which breeds to completely steer clear of. You will learn which poultry breeds have been used for hundreds of years on small farms everywhere and which ones are rarely used and for what reasons. Whether you are starting a farm and need a half dozen good poultry breeds for your coups or are just adding a small area on your property to raise some chickens, this guide will provide everything you need to understand and select the proper breed for your needs.

Book Description
The overall goal of this study was to characterize the genetic diversity of the Vietnamese local chicken breeds and to identify population priorities for conservation. The specific aims were 1) to assess and explain the population genetic structure of the Vietnamese breeds, 2) to characterize the Vietnamese breeds in relation to the Chinese breeds and wild chickens, 3) to estimate conservation potentials for conservation priorities of the Vietnamese breeds, and 4) to define an optimal allocation of limited conservation funds to them. First genetic diversity within and between the Vietnamese breeds was analysed at the autosomal level using 29 microsatellites. A total of 353 individuals of nine Vietnamese local breeds and two breeds of Chinese origin were studied. The Vietnamese breeds were sampled from the northern and southern parts of Vietnam while the two Chinese breeds (NIAS Chinese breeds) have been kept at the National Institute of Animal Sciences, Hanoi. The results revealed a high level of diversity within Vietnamese breeds. Analysing the genetic structure using the software package STRUCTURE suggested an optimal clustering at K = 6. These groups encompassed four homogeneous clusters, one formed by the two Chinese breeds and the other three representing a single breed each: the Mekong Delta breed Ac, the South Central Coast breed Choi, and the Red River Delta breed Dong Tao. The six remaining breeds formed two additional admixed clusters. This finding indicates that sub-structuring of the Vietnamese chicken breeds is related to their geographical distribution. The two NIAS Chinese breeds are genetically distinct from the Vietnamese breeds. Mitochondrial DNA D-loop sequences were used to determine the degree of shared mtDNA haplotypes between the studied breeds. A 455-bp fragment of the mtDNA Dloop region was sequenced in 222 chickens of nine Vietnamese breeds and two NIAS Chinese breeds. As reference, a skeleton was created based on chicken mtDNA sequences taken from the Genbank which assigned clades to suggested regions of domestication in chickens. Haplotypes of the nine Vietnamese and two NIAS Chinese breeds were aligned together with these sequences. The mtDNA haplotypes formed eight clades. The majority of individuals of the two NIAS Chinese breeds grouped together in one clade. Although the Vietnamese breeds were distributed across all eight clades, most of them clustered in three main clades originating from Yunnan, South and Southwest China and/or surrounding regions. The differentiation of Vietnamese breeds from Chinese chickens was characterised. For this, as reference, data of 14 indigenous breeds from China (Reference Chinese breeds) and three Red Jungle Fowl populations (Gallus gallus gallus and Gallus gallus spadiceus) genotyped at the same microsatellite loci in a previous study were included. Analysing the genetic structure indicated that the Vietnamese breeds formed a homogeneous group separated from the other breeds (except for the Chinese Chahua breed). This finding provides additional evidence that the Vietnamese gene pool is genetically different from the Chinese gene pool even when a wider range of breeds is considered. Another analysis was also used to find the degree of uniqueness of the Vietnamese breeds relative to a set of three Red Jungle fowl populations. Compared to the reference Chinese breeds, the contribution of the Vietnamese breeds to the set of Red Jungle Fowl populations is lower. This suggests that the Vietnamese breeds are more closely related to the Red Jungle fowl populations than the reference Chinese breeds. The second objective of this thesis was to estimate the conservation potential of the Vietnamese breeds and to derive optimal allocation of conservation funds to maximize genetic diversity conserved between these breeds. The Weitzman approach for assessing alternative conservation strategies for genetic diversity between breeds was used. The approach combines genetic diversity assessed at the molecular level and extinction probabilities estimated by socio-economic factors to derive conservation priorities of breeds based on their conservation potential. To investigate an optimal allocation of conservation funds, three different models were applied. These models reflect the range of possible functions between costs and effects in typical conservation situations. Under the assumptions made it is expected that half of the genetic diversity of the Vietnamese breeds will be lost within the next 30–50 years if no conservation efforts are taken. Conservation potential of the Vietnamese chicken breeds varies considerably. The optimum conservation strategy to maximise genetic diversity between the Vietnamese breeds should prioritize the breeds with the highest conservation potential. Population priorities for allocation of conservation funds to the Vietnamese breeds do not depend on which cost model was used. The three local breeds Te, Dong Tao and Ac have the highest conservation potential and should be the prime candidates for conservation programs.

Book Description
Popular Poultry Breeds examines forty mainstream breeds of chickens and bantams divided into thirty-five chapters. Most breeds exist in several plumage colour varieties, and in large and bantam (miniature) size versions, all of which are also included in this comprehensive book. Detailed histories of each breed are given, in many cases including the names of the breeders and where they lived. Also, the special management and selective breeding requirements needed for certain breeds is studied, even if they are not going to be entered into shows. The book includes helpful descriptions of the breeds, and is beautifully illustrated in full colour with over 180 photographs of prize-winning birds and nearly ninety reproductions of exquisite old prints of artist's drawings. This painstakingly researched reference work is aimed at smallholders, hobbyist poultry keepers, serious enthusiasts and those researching chicken breeds.
