Book Description
In most breeding programs of plant and animal species, genetic data (such as data from field progeny tests) are used to rank parents and help choose candidates for selection. In general, all selection processes first rank the candidates using some function of the observed data and then choose as the selected portion those candidates with the largest (or smallest) values of that function. To make maximum progress from selection, it is necessary to use a function of the data that results in the candidates being ranked as closely as possible to the true (but always unknown) ranking. Very often the observed data on various candidates are messy and unbalanced and this complicates the process of developing precise and accurate rankings. For example, for any given candidate, there may be data on that candidate and its siblings growing in several field tests of different ages. Also, there may be performance data on siblings, ancestors or other relatives from greenhouse, laboratory or other field tests. In addition, data on different candidates may differ drastically in terms of quality and quantity available and may come from varied relatives. Genetic improvement programs which make most effective use of these varied, messy, unbalanced and ancestral data will maximize progress from all stages of selection. In this regard, there are two analytical techniques, best linear prediction (BLP) and best linear unbiased prediction (BLUP), which are quite well-suited to predicting genetic values from a wide variety of sources, ages, qualities and quantities of data.

Book Description
This volume presents selected issues in the complex and diverse science of animal husbandry. The use of computer programs provides an opportunity to improve breeding and optimize farm management. At the same time, the use of traditional breeding methods is also of decisive importance. Knowledge of animal welfare and animal wellness is of great help in controlling animal health issues and in economic production. In the biological processes of reproduction of dairy cows, the events of the 100 days after calving are of fundamental importance. Production systems influence the process of product production, in which the relationship between animal products and human health goes far beyond animal husbandry, and to which the issue of greenhouse gases is also connected. The quality of manufactured meat products is influenced by both on-farm and off-farm factors, but good meat cannot be produced from low-quality animals, even with excellent slaughterhouse work. Background knowledge of animal health ‒ including the microbiome in the digestive tract, which makes use of the feed ‒ makes this activity more effective, which is of particular importance in the case of broiler chickens. Knowing the behavioural characteristics of animals (rams) enables better management. Many horse breeds are capable of artificial gaits as a result of breeding and selection processes. Comparative knowledge of the movements of these horse breeds also helps to understand their differences. The quality of life of animals and the quality of manufactured products are also affected by polycyclic aromatic hydrocarbons from the environment, which, being stored and enriched in fat-containing tissues, can also have adverse effects on the human consumer. Each topic presented not only offers specialist knowledge but makes interesting reading in its own right.

Book Description
"TODAY, about 40 percent of households in the United States share their homes with at least one dog, comprising a total of more than 61 million dogs. The multibillion dollar pet food industry and the more than seven billion dollars that pet guardians spend on veterinary care each year provide tangible evidence of the increasing importance that dogs have in our society"--

Book Description
The genetic improvement of fish for aquaculture and related fisheries has seen huge advances over recent years. Building upon the previous two editions of Aquaculture and Fisheries Biotechnology: Genetic Approaches, this 3rd edition offers a presentation of traditional selective breeding, modern genetic biotechnology, genomics, gene transfer and gene editing, and the latest developments in genetic biotechnology such as epigenetics, xenogenesis and genome-wide association study coupled with commercial application, the impact of government regulation and expectations for the future. It provides a firm grounding in relevant aspects of classical genetics, before focusing on particular aspects such as sex reversal and breeding as applied in aquaculture and fisheries. It also explores how more recent molecular genetics, genomics and biotechnology techniques can be used and combined in improvement programmes for fish and aquaculture species. A glossary explains the latest terminology used in biotechnology and genetics. This book will be useful for research scientists and students in marine biotechnology, aquaculture biotechnology, and fish genetics and breeding.

Book Description
This book attempts to present a readable format on plant breeding principles and their application, based on the collective experience of the three authors, but with a heavy dependence on the scientific literature. Modem pedagogy recognizes that teaching can occur when students are motivated to learn. Subject matter must be communicated in an interesting, appealing, and understandable fashion. In preparing the text, every effort has been made to translate pertinent plant breeding references into a clear, logical, and comprehensible format for those studying the challenging and dynamic field of plant breeding.
