When the late Reg Scott wrote the first edition of this book in 1981, his intention was 'to produce a script generally interesting to those readers requiring more information on cheese'. It was not conceived as a book that covered the most recent developments with respect to lipid or protein chemistry, for example, but rather it was hoped that the text would reveal cheesemaking as a fascinating, and yet technically demanding, branch of dairy science. The fact that the author had some 50 years' experience of cheesemaking gave the book a very special character, in that the 'art' of the traditional cheesemaker emerged as a system that, in reality, had a strong scientific basis. Today, cheesemaking remains a blend of'art and science' for, while much cheese is made in computer-controlled factories relying on strict standard ization to handle the large volumes of milk involved, the production oftop quality cheese still relies on the innate skill of the cheesemaker. It was considered appropriate, therefore, that this revised edition ofCheesemaking Practice should include, at one end of the spectrum, details of the latest technology for curd handling and, at the other, simple recipes for the production of farmhouse cheeses. Obviously a student of dairy science will need to consult other texts in order to complete his/her knowledge of the cheesemaking process, but if this revised edition stimulates its readers to delve more deeply, then the task of updating the original manuscript will have been worthwhile."

This open access book provides the first critical history of the controversy over whether to cull wild badgers to control the spread of bovine tuberculosis (bTB) in British cattle. This question has plagued several professional generations of politicians, policymakers, experts and campaigners since the early 1970s. Questions of what is known, who knows, who cares, who to trust and what to do about this complex problem have been the source of scientific, policy, and increasingly vociferous public debate ever since. This book integrates contemporary history, science and technology studies, human-animal relations, and policy research to conduct a cross-cutting analysis. It explores the worldviews of those involved with animal health, disease ecology and badger protection between the 1970s and 1990s, before reintegrating them to investigate the recent public polarisation of the controversy. Finally it asks how we might move beyond the current impasse.

How do we achieve food security for a global population now over 7 billion people and trending towards 10 billion by 2050? This study of the global dairy industry examines how to balance our needs with those of animals and the environment. It scrutinises ruminant bovines' worrying exhaling of methane, a greenhouse gas which, fortunately, evidence shows can be reduced by adding seaweed to cattle feed. Are the multi-thousand-cow mega-dairies of the USA appropriate models for Africa and Asia's high-growth dairy regions, where so many women are smallholders? Is it ethical to keep cows in confined animal feeding operations (CAFOs), eating unnatural high-energy/low fibre diets when they prefer grazing pasture? Other issues include hormones for oestrus stimulation, and GMOs for milk yield, stressing cows' immune systems and drastically shortening longevity. This book offers multifaceted discussion of the central and ancillary issues relevant to dairying, and consumption of plant- and laboratory-based foods in the 21st century. No book to date offers such a comprehensive overview, linking ethics, environment, health and policy-making with in-depth coverage of the major dairy farming regions of the world.

Livestock Ration Formulation for Dairy Cattle and Buffalo provides an interdisciplinary, integrative perspective and optimization on dairy cattle feed formulation problem solving. It helps dairy farmers by introducing them the right frequency and right amount of balanced diet to be fed to cattle's and buffaloes at different body condition so that their feeding cost should be decreased and there should be increase in income for dairy farmers, as they don't have enough knowledge of feeding practice. It helps animal nutritionist to work for dairy farmers which have very limited feed resources to fulfil nutrients requirement in terms of crude protein (CP), total digestible nutrient (TDN), calcium (Ca) and phosphorus (P) by developing a software programme to plan a balanced low budget diet. It includes the Linear and Goal programming model for non-pregnant dairy buffalo is been solved using Hybrid Real Coded Genetic Algorithm and the results are compared with Real Coded Genetic Algorithm (RGA) considering different versions like RGA without crossover, RGA without Mutation, RGA with crossover and mutation. These models can also be applied with other nutritional models like CNCPS, INRA. This book is a step forward in that direction to provide least cost diet formulation based on nutrient requirement of the cattle and buffalo, which is been calculated according to Indian Council of Agricultural Research (ICAR, 2013) and NRC (2001) on dry matter basis, provides a clear and precise platform for other researcher in Animal Nutrition field which also give initial platform to build a software and android application to formulate least cost ration Based on data and algorithm used in this book, which helps Dairy farmers directly to feed balanced diet at cheap rate. Features: It is a good reference to local dairy farmers by introducing them to the right frequency and right amount of balanced diet to be fed to cattle and buffaloes at different production cycles. It will provide basic platform and some solutions to built-up software about cattle nutrition development and least cost formulation for end-user. It has several techniques for optimizing animal diet formulation but a good balance between coding/programming and animal nutrition is incorporated towards application of soft computing technique to improve the quality of the solution due to rigidity of the constraints.

India imposes stringent criminal penalties, including life imprisonment in some states, for cow slaughter, based on a Hindu ethic of revering the cow as sacred. And yet India is among the world's leading producers of beef, leather, and milk, industries sustained by the mass slaughter of bovines. What is behind this seeming contradiction? What do bovines, deemed holy in Hinduism, experience in the Indian milk and beef industries? Yamini Narayanan asks and answers these questions, introducing cows and buffaloes as key subjects in India's cow protectionism, rather than their treatment hitherto as mere objects of political analysis. Emphasizing human–animal hierarchical relations, Narayanan argues that the Hindu framing of the cow as "mother" is one of human domination, wherein bovine motherhood is simultaneously capitalized for dairy production and weaponized by right-wing Hindu nationalists to violently oppress Muslims and Dalits. Using ethnographic and empirical data gathered across India, this book reveals the harms caused to buffaloes, cows, bulls, and calves in dairying, and the exploitation required of the diverse, racialized labor throughout India's dairy production continuum to obscure such violence. Ultimately, Narayanan traces how the unraveling of human domination and exploitation of farmed animals is integral to progressive multispecies democratic politics, speculating on the real possibility of a post-dairy society, based on vegan agricultural policies for livelihoods and food security.

Recent IPCC reports have highlighted the environmental impact of livestock production as a major source of non-CO2 emissions: methane (CH4), nitrous oxide (N2O) and ammonia (NH3). The livestock sector must react to these reports and develop or implement methods that can reduce greenhouse (GHG) emissions from livestock production. Reducing greenhouse gas emissions from livestock production provides authoritative reviews on measuring GHG emissions from livestock as well as the range of methods that can be applied to reduce emissions, ranging from breeding to animal health and manure management. The collection also reviews nutritional approaches such as improving forage quality and the use of plant bioactive compounds and other feed supplements to limit emissions by modifying the rumen environment. Drawing in an international range of expert authors, Reducing greenhouse gas emissions from livestock production summarises what we can do to make livestock production more sustainable and viable for the future. It will be a major reference for the livestock (particularly dairy) science research community, environmental scientists, government and other agencies tackling the challenge of climate change, as well as companies involved in livestock production and processing of dairy and meat products.

Biotechnology is expected, by many observers, to have a significant impact on the world dairy industry over the next decade. In this timely volume, Lovell Jarvis analyzes the potential effect of two biotechnologies-multiple ovulation and embryo transfers (MOET) and recombinant bovine somatotropin (rbST-on the dairy industry around the world. According to Jarvis's research, the effects of these two technologies will vary greatly between the developed and developing nations. He predicts that the technologies will be most profitable for the developed nations, where their use will increase milk production and strengthen their positions in dairy export markets. Developing country dairy sectors will probably lose from the use of these two biotechnologies, as their own international trade position will be weakened, though their own consumers should benefit. Jarvis concludes his study with a look at alternative approaches that might improve the competitive position of developing countries in the dairy sector.

This two-volume work was first published in 1987. This second edition covers all the subjects treated in the first edition with many revisions and updates, and the addition of several new topics.

Milk is a highly perishable commodity; heat treatment or pasteurization can be used to make fresh milk safe to drink, but these methods do not destroy the spoilage organisms. Processing milk into ordinary dairy products extends its shelf-life, reduces wastage and adds value to the milk, creating more income for the producer. In addition, processing converts the lactose in milk into lactic acid, making dairy products to those who suffer from lactose intolerance.;This book outlines traditional methods of processing milk to produce cheese, butter, yoghurt and other milk products, and discusses how hygiene and quality control can be improved, essential if the quantities of milk produced are to be increased beyond the household level to give increased income.;"Dairy Processing" avoids introducing completely new products or processes, but suggests low-cost modifications to traditional methods which can be and have been introduced successfully. Case studies describe the introduction of improved businesses around the world, and there is a list of useful organizations. This book is part of the "Food Cycle Technology Source Books Series". Designed for people who have no technical background
