Book Synopsis Improving Animal Welfare through Genetic Selection by : Wendy Mercedes Rauw
Download or read book Improving Animal Welfare through Genetic Selection written by Wendy Mercedes Rauw and published by Frontiers Media SA. This book was released on 2016-07-12 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In livestock species, breeding goals are aimed primarily at improvement of production traits. However, there are a number of examples where selection for high production efficiency has resulted in reduced welfare through unfavorable outcomes in health and fitness characteristics. These effects raise questions about what is ethically acceptable in animal breeding. Welfare problems may be experienced when physiological balance is disturbed by genetic selection for high production alone, by a mismatch between the environmental challenges and the range of coping responses available to an animal, or from a mismatch between the animal’s needs and their degree of satisfaction. This may be resolved by either improving the environment to support the animal, but also by providing the animal, through genetic selection, with means to adapt to the production environment. The Standing Committee of the European Convention for the Protection of Animals kept for Farming Purposes emphasizes that breeding goals should include health and welfare. The Farm Animal Welfare Council pleas for a greater emphasis in breeding programs on traits associated with good welfare. However, although breeding goals in most farm animal species have been broadened beyond production traits to include functional traits, behavioral traits are rarely included despite their potential to improve animal production and welfare. It is the goal of the present Research Topic to bring together experimental and theoretical research focusing on the genetics of welfare traits and the possibility to improve animal welfare through selection. This topic presents an overview of the relationship between selection for high production and livestock robustness, examples of improving robustness through the introduction of novel traits in livestock breeding, and a discussion on selection methods to address welfare issues. The discussion on sustainability of breeding practices is very alive today and will remain to be an important part of the debate in the future.

This book was released on 2013-04-22 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: In these classic experiments, quail chicks were selectively bred for the behavioral traits of fear and social reinstatement. Over a period of 20 generations, four separate genetic lines were created. They were high and low fear and high and low social re-instatement. The duration of tonic immobility was used as a measure of fear and social reinstatement was measured with a treadmill test. In this test, the time that a bird will walk on a treadmill to stay close to its flockmates is measured. Since the publication of this chapter in 1998, many scientists have carried out with these genetic lines. Duration of tonic immobility does not all measure all types of fear. Fear maybe multidimensional because selection for tonic immobility has little effect on behavioral reactions to novelty. More recent research has also discovered linked traits such as low social reinstatement birds have stronger ultradiam rhythms.

Available in PDF, EPUB and Kindle. Book excerpt: Over-selection for production traits has caused animal welfare problems such as feather pecking in hens, tail biting in pigs, and overly aggressive animals. In dogs, over-selection for appearance traits has caused neurological problems such as deafness. Both feather pecking and tail biting may be displaced foraging behaviors, because these behaviors are reduced by providing foraging materials such as straw. Another problem is hunger in broiler breeder hens and breeding sows. Animals that have been selected for rapid growth are also selected for a huge appetite. If breeder animals eat to satiation, they will become obese and have health problems. High-roughage feeds may improve welfare. Researchers suggest that new genetic breeding tools could be used to select against harmful behaviors and still have a productive animal. Breeders must avoid creating animals that will have poor welfare even when they are housed in the best environment.

Available in PDF, EPUB and Kindle. Book excerpt: This newly updated and revised volume of the Encyclopedia of Sustainability Science and Technology (ESST) details the role of Animal Breeding and Genetics in the sustainability of animal agriculture. The volume covers scientific principles and applications includes the current science used to advance cattle, poultry, swine,sheep, and equine populations, as well as the future role of techniques such as gene editing. International leaders in the field explain foundational concepts such as heritability, the covariance between relatives, statistical approaches to predicting the genetic merit of individuals, and the development and advancement of molecular techniques to elucidate changes in the DNA sequence that underly phenotypic variation. The use of genetic-based tools to improve animal agriculture and meet consumer demands across species is treated in detail. Readers will gain an understanding of how global livestock producers have implemented advanced genetic selection tools and used them to improve reproduction, production, efficiency, health, and sustainability. The interactions of genetics and production environments, and the genetic components of the complex interactions among animals are also discussed. The future of Animal Breeding and Genetics, including the challenges and opportunities that exist in feeding a growing world population, are addressed.
Book Synopsis Genetics and the Behavior of Domestic Animals by : William M. Muir
Download or read book Genetics and the Behavior of Domestic Animals written by William M. Muir and published by Elsevier Inc. Chapters. This book was released on 2013-04-22 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many behaviors in poultry can be modified by genetic selection. Selection of laying hens for maximum egg production had the unfortunate side effect of increased rates of beak inflicted damage on other birds. Selective breeding has eliminated broodiness and has either increased or decreased other behaviors, such as hysteria, fearfulness, appetite in broilers, social dominance, ability and damage to other birds. Genetic selection can be used to reduce behaviors that cause welfare problems. However, it must be approached with caution to avoid unintended consequences that would be detrimental to welfare. A calm, docile bird that appears behaviorally calm, may take longer for its heart rate to return to normal after it is frightened. The use of group selection instead of single-bird selection can be effectively used to reduce undesirable behaviors such as feather pecking and to maintain high egg production. An entire group of birds is selected instead of selecting individuals.

Book Synopsis Genetics and the Behavior of Domestic Animals by : Alain Boissy
Download or read book Genetics and the Behavior of Domestic Animals written by Alain Boissy and published by Elsevier Inc. Chapters. This book was released on 2013-04-22 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter provides an overview of the current behavioral and cognitive aspects of emotions in animals and explore the impacts of emotional experiences on the animal's adaptation to its current challenging circumstances. There is evidence that animal welfare results from the animal's perception of its environment and its background. The chapter is structured in four complementary sections. The first one addresses the nature of emotions that the animals can feel which is validated from commonalties in physiological and behavioral responses to dangers across and within species. The second section presents advanced features of the relationships between cognition and emotions originally studied in humans, which are now developed in animals to better access their affective states. The third section is devoted to the relevance of the personality concept, as resulting from both genetics and developmental experience, for assessing animal individuality in emotional behaviors and stress. The last section explores some approaches that can alleviate fear and induce positive affective states, with the potential to mitigate detrimental stress-induced effects on the welfare and health status by eliciting positive emotions in animals.

Download or read book Improving farm animal welfare written by H.J. Blokhuis and published by Springer. This book was released on 2013-05-31 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do you define the quality of life of a farmed animal? This timely book addresses the complex and often controversial issues surrounding the assessment and improvement of farm animal welfare. Based on a large, multi-disciplinary EU funded research project called Welfare Quality, it discusses the relevance of science based welfare assessments and the importance of establishing a fruitful dialogue between science and society. An outline is given of the development of a workable welfare assessment system for cattle, pigs and chickens as well as practical ways of improving the animals' quality of life. This book synthesises the huge body of work carried out by the largest ever international network of scientists and stakeholders in Welfare Quality. It describes some of the obstacles encountered and their solution and why particular paths were chosen. It also clearly sets out what still needs to be done and presents selected strategies and technologies (automation, proxy indicators, targeting of risk factors, etc.) designed to ensure the continued improvement of welfare and its assessment. The book provides a valuable source of knowledge on farm animal welfare for social and animal scientists, students, teachers, policy makers, lobby groups and the animal industry.
