Art and Science in Breeding by Margaret Elsinor Derry Pdf

Chickens are now the most scientifically engineered of livestock. How have the methods used by geneticists differed from those employed by domestic breeders over time? Art and Science in Breeding details the relationship between farm practices and agricultural genetics in poultry breeding from 1850 to 1960. Margaret E. Derry traces the history and organization of chicken breeding in North America, from craft approaches and breeding as an 'art,' to the conflicts that had emerged between traditional and scientific methods by the 1940s. Derry assesses links between the 'scientific' revolution of chicken farming and the development of corporate breeding as a modern, international industry. Using poultry as a case study for the wider narrative of agricultural genetics, Art and Science in Breeding adds considerable knowledge to a rapidly growing field of inquiry.

Beauty or Statistics by Bert Theunissen Pdf

In the 1970s, scientists claimed that farm animal breeding was finally evolving from an art into a science. In their view, the switch to scientific breeding was as inevitable as the ongoing process of agricultural modernization. However, the art-to-science scenario is too simplistic to do justice to the complex dynamic that characterized the transformation of the field. The livestock breeds that take centre stage in this book – dairy cattle, chickens, pigs, sheep, and horses – were products of the twentieth century. The methods used by breeders to improve their animals, however, were much older. Tracing the history of practical stockbreeding, the role of Mendelism in scientific breeding, and the emergence of quantitative genetics, Beauty or Statistics shows that the story of the scientific modernization of livestock breeding can be more fruitfully analysed from the perspective of changing cultures of breeding, taking practical, commercial, normative, and aesthetic considerations into account.

Breeding Dendrobium Orchids in Hawaii by Haruyuki Kamemoto,Teresita D. Amore,Adelheid R. Kuehnle Pdf

Dendrobium orchids have been among Hawaii's most popular plants since Dendrobium anosmum, with its hanging pseudobulbs and delightfully fragrant flowers, was introduced from the Philippines in 1896. Four decades later the Islands' first Dendrobium hybrid was registered, and by the 1950s, coinciding with the advent of the University of Hawai'i's orchid research program, Hawaii was established as the center for Dendrobium hybridization. Dendrobiums have since become the single most valuable commercial flower in Hawaii, given their combined use for cut-flowers, leis, and blooming potted plants. Breeding Dendrobium Orchids in Hawaii summarizes for easy reference research on cytogenetics and breeding of dendrobiums conducted over the past 47 years, mainly at the University of Hawai'i. A lavishly illustrated section on species important to Hawaii's orchid industry is followed by a description of the origin of many popular hybrids. Throughout, information on cross-breeding, seed propagation, flower color and form, and controlling disease is presented in language readily understood by the layperson. A total of 175 color photographs showcase registered hybrids, cut-flower cultivars, potted plant cultivars, and novelties. The authors share valuable tips on counting Dendrobium orchid chromosomes, germinating seeds, and cloning plants and provide a comprehensive glossary. Breeding Dendrobium Orchids in Hawaii will be an essential reference for anyone associated with orchids-growers, hobbyists, breeders, tissue culture propagators, plant geneticists, and horticultural scientists.

Horse Breeds and Breeding in the Greco-Persian World by Thomas Donaghy Pdf

Although there are many publications which discuss the history of the ancient horse, few focus their attention on the origin and development of the various breeds. Most publications examine the horse’s contribution to human history through its role as transport facilitator and military machine, and concentrate mainly on subjects such as the origin and development of chariot and cavalry equipment and changes in military tactics over time. This book examines what happened when humans took the horse from the wild and domesticated it for their own use. This focus was taken as it was felt that the understanding of the huge role which the horse played in human history can only be improved by gaining an understanding of the equally huge role which humans played when they took horses from the wild and, through many hundreds of years of daily interaction, cross-breeding, and training, facilitated the development and spread of many breeds across the ancient world. This book takes as its chronological focus the Greco-Persian world of the second and first millennia BC. This time period was selected for examination as it was during these two millennia that the vital role which the horse was to play in human history became fully apparent. The second millennium BC saw the development of the vast chariot forces which were to form an important part of the armed forces of numerous lands, from Mycenaean Greece in the West to India and China in the far East, while the following millennium saw the gradual replacement of chariots with cavalry forces, which continued to play a vital role in military warfare right up until the beginnings of the twentieth century AD. Part One traces the history of the horse from its evolution to the development and spread of chariot and cavalry forces. Parts Two and Three examine the famous horse-breeding regions of the ancient world and, through an analysis of archaeological, iconographical, and literary evidence, attempts to determine why these regions were famed for horse breeding and what were the physical characteristics and given attributes of the various breeds.

Animal Breeding, Welfare and Society by Jacky Turner Pdf

The determination of when, how, how often and with whom an animal breeds is moving rapidly away from evolutionary pressures and towards human purposes: these include the breeding of around 50 billion mammals and birds for food production annually, the breeding of pedigree dogs and cats, racing dogs and horses, specialised laboratory animal strains and the use of reproductive science to conserve endangered species or breeds and to limit unwanted populations of pests and non-native species. But the ethics and sustainability of this takeover of animals' reproductive lives have been insufficiently examined by either professionals or the public. This book discusses the methods, the motivations and the consequences of human intervention in animal breeding in terms of animal health, behaviour and well-being. It explores where we are now and the choices ahead, and looks to a future where we have more respect for animals as sentient beings and where we could loosen the reins of reproductive control.

A Taste for the Beautiful by Michael J. Ryan Pdf

"In A Taste for the Beautiful, Michael Ryan, one of the world's leading authorities on animal behavior, tells the remarkable story of how he and other scientists have taken up where Darwin left off, transforming our understanding of sexual selection and shedding new light on animal and human behavior. Drawing on cutting-edge science, Ryan explores the key questions: Why do animals perceive certain traits as beautiful and others not? Do animals have an inherent sexual aesthetic and, if so, where is it rooted? Ryan argues that the answers lie in the brain--particularly of females, who act as biological puppeteers, spurring the development of beautiful traits in males."--Back cover
