Download or read book Breeding for robustness in cattle written by Marija Klopcic and published by BRILL. This book was released on 2023-09-04 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has revealed unfavourable trends in e.g. fertility, udder health and locomotion in some major dairy cattle breeds due to a large increase in production and insufficient consideration of functional traits in the breeding goals. Such unfavourable trends in some functional traits increase costs. Additionally, the enlargement of herds leads to less available labour time per individual cow. This asks for cows that are easy to handle. At the same time, society is demanding a higher welfare standard of animals. These contradicting developments have increased the desire for so called more robust animals. Robustness can be defined as 'the ability to maintain homeostasis in commonly accepted and sustainable herds of the near future'; or 'the ability of the cow to function well in the environment she lives in as well as in a wide range of climates and production systems'. This book contains a series of articles (26) dealing with the concept of robustness, including aspects like evolution, genetics, environment, animal health and welfare, and integrity. Besides the major functional traits also the links to energy balance, hot climatic conditions, and the attitude and input of stakeholders towards robustness as part of the breeding program are discussed. This book is the first attempt to summarise the available knowledge concerning this topic in cattle, making this book unique. The contributions are from authors of 16 countries from all over the world. However, the focus is presently on farm animal level, while in future robustness of the whole production system may also require additional attention.

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.

Download or read book Animal Breeding written by Gerald Wiener and published by MacMillan Education, Limited. This book was released on 1994 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide to animal breeding in tropical countries explains what can and cannot be achieved. It starts by dealing with basic genetics and then deals with the various techniques used in animal breeding - selection, crossbreeding and inbreeding, and the effects that each of these can have on the animal populations. The author gives examples of each and points out their limitations when applied in the tropics. He also identifies systems of potential value, such as the use of multiple ovulation and embryo transfer. The book deals with specific considerations, such as the effect of climate on animals, the problems faced when dealing with tropical species, such as buffalo, and factors to take into consideration when dealing with individual traits.

Available in PDF, EPUB and Kindle. Book excerpt: Bringing together the experience of three top academic experts in breeding procedure, this up-to-date edition of Managing Breeds for a Secure Future examines breeding and genetics at a level accessible to all. This new edition has been revised to cover emerging debates in animal breeding and includes domestic species, such as dogs and horses. The authors skillfully use a clear discussion of theoretical genetics to explain its practical applications to a wide audience of livestock and domestic animal breeders. Specific examples are provided throughout to illustrate how decisions regarding breeding and management relate back to genetic theory. Advice is given on all areas pertaining to the process of responsible breed management from selecting pairs and mating systems to registry functions and long-term management. Current topics of interest covered include: breeding for robustness and disease resistance, international movement of livestock, and preserving endangered breeds. Breed associations are also discussed in depth with particular emphasis on how reducing common conflicts can secure the future of breeds for generations to come. This practical book offers a comprehensive examination of breeding practices aimed at livestock and dog breeders of all abilities and experience levels. The first edition was published by The Livestock Conservancy. *** "...an excellent resource for breed conservation and management. ...many examples from both rare and populous breeds. ...provide[s] practical recommendations that cover theoretical, political, and organizational aspects of breed preservation.... This book is important reading for any veterinarian, breeder, or owner interested in the hands-on management of breeding and breed conservation. ...accompanied by many photographs, figures, tables, and diagrams of breeds and breeding schemes. It allows readers to understand the different goals and emphases of various domestic animal species, as well as the market forces that affect breed management." --Journal of the American Veterinary Medical Association, Vol. 251, No. 12, December 15, 2017 [Subject: Farm Life, Animal Breeding & Management, Animal Husbandry, animal conservancy, genetics]

Download or read book INRA feeding system for ruminants written by INRA and published by BRILL. This book was released on 2023-11-27 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: The INRA Feeding System for Ruminants has been renewed to better address emerging challenges for animal nutrition: prevision of productive responses, product quality, animal health and emissions to the environment, in a larger extent of breeding contexts. The new system is mainly built from meta-analyses of large data bases, and modelling. The dietary supply model accounts for digestive interactions and flows of individual nutrients, so that feed values depend on the final ration. Animal requirements account for variability in metabolic efficiency. Various productive and non-productive animal responses to diets are quantified. This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas. The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins. Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes. Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transition phase of dairy cows is marked by severe metabolic stress resulting from a discrepancy of a high energy demand for rapidly increasing milk production and limited feed intake. Here, a failure in metabolic adaptation results in an increased susceptibility to health problems. However, even under the same environmental factors and production lev-el, the variability of how each cow deals with metabolic load is substantial, leading to the hypothesis that there might be an underlying genetic basis. The main goal of this thesis is to study this genetic basis from different points of v...
