Genetics and the Behavior of Domestic Animals by Temple Grandin,Mark J. Deesing Pdf
Behavior is shaped by both genetics and experience--nature and nurture. This book synthesizes research from behavioral genetics and animal and veterinary science, bridging the gap between these fields. The objective is to show that principles of behavioral genetics have practical applications to agricultural and companion animals. The continuing domestication of animals is a complex process whose myriad impacts on animal behavior are commonly under-appreciated. Genetic factors play a significant role in both species-specific behaviors and behavioral differences exhibited by individuals in the same species. Leading authorities explore the impact of increased intensities of selection on domestic animal behavior. Rodents, cattle, pigs, sheep, horses, herding and guard dogs, and poultry are all included in these discussions of genetics and behavior, making this book useful to veterinarians, livestock producers, laboratory animal researchers and technicians, animal trainers and breeders, and any researcher interested in animal behavior. Includes four new chapters on dog and fox behavior, pig behavior, the effects of domestication and horse behavior Synthesizes research from behavioral genetics, animal science, and veterinary literature Broaches fields of behavior genetics and behavioral research Includes practical applications of principles discovered by behavioral genetics researchers Covers many species ranging from pigs, dogs, foxes, rodents, cattle, horses, and cats
Genetics and the Behavior of Domestic Animals by Peter J. Chenoweth,Antonio J. Landaeta-Hernández,Cornelia Flöercke Pdf
This chapter describes the reproductive and maternal behaviors of different livestock species (cattle, horses, pigs, goats, and water buffalo) with an emphasis on those traits which are genetically conserved. All of the species discussed are polygynous and promiscuous, and females undergo estrous cycles in which males are mainly attracted by movement and posture cues. Major differences in both reproductive and maternal behaviors are observed between “prey” and “predator” type species. Genetic variation also occurs within species, with breed and line differences being observed in all of the behaviors discussed, allowing selection for optimal reproductive and maternal behaviors. However, modern livestock systems, which emphasize production traits, can diminish reproductive and maternal traits and increase detrimental behaviors, such as piglet crushing and savaging in sows. With modern selection tools, greater emphasis on positive reproductive and maternal traits is achievable within the context of profitable production.
Polymeric Nanoparticles for Bovine Mastitis Treatment by Ali Haider,Muhammad Ikram,Iram Shahzadi,Muhammad Asif Raza Pdf
This book features an in-depth examination of the ongoing problem of bovine mastitis and the potential solutions offered by polymer nanoparticles. With extensive research and analysis, the book delves into the causes and consequences of bovine mastitis, including the shift in the relevance of various infections and the increasing problem of antibiotic resistance. The authors explore the use of nanoparticles as a potential alternative to traditional antibiotics and the importance of tailoring their characteristics for specific uses. Detailed discussions of the pros and cons of different manufacturing procedures and characterizations of bovine mastitis, drug-resistant bacteria, and resistance development make this monograph an invaluable resource for researchers and experts in the field of veterinary medicine, and an excellent resource for those interested in investigating the viability of nano-materials as future antibiotic alternatives.
Progress in Research on Energy and Protein Metabolism by W.B. Souffrant,C.C. Metges Pdf
"This book compiles the scientific content of the International Symposium on Energy & Protein Metabolism and Nutrition, in Rostock-Warnemünde 13th-18th September 2003. Specialists from all over the world working in energy and protein metabolism research were assembled to discuss scientific matters of physiology, nutrition, immunology and genetics. All scientific contributions, presented as oral communications or posters, are published in this book. Additionally to these more than 150 articles and 10 review papers, presented by invited speakers, give an overview of the state of the art in special research areas of energy and protein metabolism. The book presents latest results in topics of energy metabolism such as environmental aspects of energy homeostasis, dietary and genetic aspects as well as tissue, organ and whole body energy metabolism and methodology. Furthermore this compilation also gives insight in current affairs of protein research, i.e. protein metabolism and microbiology in the gastro-intestinal tract and requirements and post-absorptive metabolism of amino acids. Apart from these specific questions other topics concerning genes and nutrition or modelling and regulation of energy and protein status were of common interest. The intention of these proceedings is to disseminate latest perceptions of energy and protein research and with this to attempt the connection of areas in animal and human life sciences."
This book is the most complete, accessible, and up-to-date resource for Ethiopian geography, history, politics, economics, society, culture, and education, with coverage from ancient times to the present. Ethiopia is a comprehensive treatment of this ancient country's history coupled with an exploration of the nation today. Arranged by broad topics, the book provides an overview of Ethiopia's physical and human geography, its history, its system of government, and the present economic situation. But the book also presents a picture of contemporary society and culture and of the Ethiopian people. It also discusses art, music, and cinema; class; gender; ethnicity; and education, as well as the language, food, and etiquette of the country. Readers will learn such fascinating details as the fact that coffee was first domesticated in Ethiopia more than 10,000 years ago and that modern Ethiopia comprises 77 different ethnic groups with their own distinct languages.
Calculation of Demographic Parameters in Tropical Livestock Herds by Matthieu Lesnoff,Renaud Lancelot,Charles-Henri Moulin,Samir Messad,Xavier Juanès,Christian Sahut Pdf
Having indicators to assess the effect of zootechnical, sanitary, economic or political intervention or the impact of environmental risks makes it possible to draw up strategies for improving domestic animal populations. This handbook is a compilation of the main concepts relating to the definition and calculation of demographic rates for largely non-intensive tropical animal farms. It is intended to be educational, and should help students, technicians, engineers, researchers and development staff to understand the definitions and formulas encountered in the literature more clearly and make them more self-sufficient in terms of analyses.
This title was first published in 2001. This study indicates that researchers have far to go in understanding and assessing how development projects work. The author shows that, often, the perception of failure is not shared by those whom were intended to benefit. She uses a case study of Samoan villagers introduced to cattle farming to examine the wider development process and challenge the conventional theories. By drawing on people-centred perspectives that give much greater weight to the role of culture in development, the volume does not simply criticize development project management, but suggests practical and positive ways forward, encouraging spontaneous indigenous development which should be supported by projects where appropriate.
