Book Description
Quantitative traits-be they morphological or physiological characters, aspects of behavior, or genome-level features such as the amount of RNA or protein expression for a specific gene-usually show considerable variation within and among populations. Quantitative genetics, also referred to as the genetics of complex traits, is the study of such characters and is based on mathematical models of evolution in which many genes influence the trait and in which non-genetic factors may also be important. Evolution and Selection of Quantitative Traits presents a holistic treatment of the subject, showing the interplay between theory and data with extensive discussions on statistical issues relating to the estimation of the biologically relevant parameters for these models. Quantitative genetics is viewed as the bridge between complex mathematical models of trait evolution and real-world data, and the authors have clearly framed their treatment as such. This is the second volume in a planned trilogy that summarizes the modern field of quantitative genetics, informed by empirical observations from wide-ranging fields (agriculture, evolution, ecology, and human biology) as well as population genetics, statistical theory, mathematical modeling, genetics, and genomics. Whilst volume 1 (1998) dealt with the genetics of such traits, the main focus of volume 2 is on their evolution, with a special emphasis on detecting selection (ranging from the use of genomic and historical data through to ecological field data) and examining its consequences.

Book Description
Nutrition and Lactation in the Dairy Cow is the proceedings of the 46th University of Nottingham Easter School in Agricultural Science. Said symposium was concerned with the significant advances in the field of nutrition and lactation in the dairy cow. The book is divided in five parts. Part I deals with the principles behind nutrition and lactation of cows. Part II discusses the cow's nutrient interactions; responses to nutrients that yield protein and energy; and the influence of nutrient balance and milk yields. Part III tackles the efficiency of energy utilization in cows and its relation to milk production. Part IV talks about food intake of cows and the factors that affect it, while Part V deals with the different feeding systems for cows. The text is recommended for those involved in raising cows and dairy production, especially those who would like to know more and make studies about the relationship of nutrition and lactation of cows.

Book Description
Cheese is a unique food product which requires a significant amount of scientific knowledge to be produced successfully. However, due to the many, complex and interrelated changes which occur during cheese manufacture and ripening, it is still not possible to guarantee the production of premium quality cheese. Written by an international team of renowned contributors, Cheese problems solved provides responses to over 200 of the most frequently asked questions about cheese and the cheese-making process, in a unique and practical question-and-answer format.Opening chapters concentrate on queries regarding the preparation of cheese milk, the conversion of milk to curd, the ripening process, pathogens, cheese analysis and nutritional aspects of cheese amongst other issues. The latter half of the book discusses particular types of cheeses such as Cheddar, Grana-type cheeses, Mozzarella, Dutch-type, Swiss and Blue cheeses, to name but a few.Edited by a leading expert and with contributions from specialists within the field, Cheese problems solved is an essential reference and problem solving manual for professionals and trainees in the cheese industry. - Provides responses to over 200 of the most frequently asked questions about cheese and the cheese-making process - An essential reference and problem solving manual for professionals and trainees in the cheese industry - Benefit from the knowledge of leading specialists in the field

Book Description
The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded
