Book excerpt: When automatic milking is combined with grazing the cows are given a unique opportunity to choose between being indoors or outdoors. Concerns have been raised about achieving sufficient number of milkings per day since the cows' motivation to be milked is low and cows are expected to go to milking voluntarily. The overall aim was therefore to examine how management routines affect cow motivation to visit the milking unit several times a day. First it was hypothesised that distance to pasture and level of supplements affects the milking frequency. The results demonstrated that cows with a shorter distance to pasture had a higher milking frequency during the first part of the grazing season and a higher milk yield compared with cows pasturing further from the barn. One important finding was that cows on the distant pasture changed their behaviour as the grazing season progressed and almost ceased to walk to their pasture area. A high level of silage supplements compared with a buffer feed offered in the barn had no affect on the milk yield. Also there was no affect on the number of milkings during the first part of the grazing season but during the latter part, cows with a high level of silage had a lower number of milkings. It was also hypothesized that it is possible to strengthen the cows' perception of a feed reward in the milking unit by training the cow to respond to a conditioned stimulus, an acoustic signal. Most of the cows learnt to approach the milking unit following the signal when they were in an enclosed area of the barn, close to the milking unit. However, when receiving the signal out on pasture the response to the signal was variable and comparatively low. Finally, the hypothesis that enhanced sensory stimulation during milking by feeding or stroking the cows' abdomen affects the level of the oxytocin and cortisol during milking was tested. Feeding during milking increased the plasma oxytocin level and milk production whereas brushing during milking d

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a number of experiments where different factors that affect milking frequency have been studied. Although some basic experiments have been performed indoors, focus has been on the pasture season and the grazing situation. Factors of importance to milking frequency that are discussed in this report are feed related factors, water supply, environmental factors and cow locomotion. The report also presents results from experiments studying the learning process of cattle with the objective to teach the animals to respond to an individual auditory signal. A cow-calling apparatus has also been tested during the pasture season to summon the individual cow to the milking unit.

Available in PDF, EPUB and Kindle. Book excerpt: Grazing management might seem simple: just put livestock in a pasture and let them eat their fill. However, as Sarah Flack explains in The Art and Science of Grazing, the pasture/livestock relationship is incredibly complex. If a farmer doesn't pay close attention to how the animals are grazing, the resulting poorly managed grazing system can be harmful to the health of the livestock, pasture plants, and soils. Well-managed pastures can instead create healthier animals, a diverse and resilient pasture ecosystem, and other benefits. Flack delves deeply below the surface of "let the cows eat grass," demonstrating that grazing management is a sophisticated science that requires mastery of plant and animal physiology, animal behavior, and ecology. She also shows readers that applying grazing management science on a working farm is an art form that calls on grass farmers to be careful observers, excellent planners and record-keepers, skillful interpreters of their observations, and creative troubleshooters. The Art and Science of Grazing will allow farmers to gain a solid understanding of the key principles of grazing management so they can both design and manage successful grazing systems. The book's unique approach presents information first from the perspective of pasture plants, and then from the livestock perspective--helping farmers understand both plant and animal needs before setting up a grazing system. This book is an essential guide for ruminant farmers who want to be able to create grazing systems that meet the needs of their livestock, pasture plants, soils, and the larger ecosystem. The book discusses all the practical details that are critical for sustained success: how to set up a new system or improve existing systems; acreage calculations; paddock layout; fence and drinking water access; lanes and other grazing infrastructure; managing livestock movement and flow; soil fertility; seeding and reseeding pastures; and more. The author includes descriptions of real grazing systems working well on dairy, beef, goat, and sheep farms in different regions of North America. The book covers pasture requirements specific to organic farming, but will be of use to both organic and non-organic farms.

Available in PDF, EPUB and Kindle. Book excerpt: "In 2000 the book Robotic Milking, reflecting the proceedings of an International Symposium which was held in The Netherlands came out. At that time, commercial introduction of automatic milking systems was no longer obstructed by technological inadequacies. Particularly in a few west-European countries, systems were being installed at an increasing rate. However, it was recognised that the changeover from 'traditional' to automatic milking affected the farming operation, herd management and control of milk quality profoundly and that many of the implications were still unknown. So, new challenges in various fields of dairy farming and new research areas emerged. Since this previous International Symposium, much has happened. In general automatic milking has been adopted as a realistic alternative for milking in the 'traditional' milking parlour. Systems have gradually been improved and, maybe even more importantly, farmers have become more familiar with their potential and limitations, both technically and in herd management. The number of farms milking with an automatic milking system has worldwide increased to more than 2.200 by the end of 2003 . From 2000 to now, the level of scientific knowledge on various aspects and consequences of automatic milking has increased largely as well because of research efforts all over the world. A significant share of these efforts has been made within the framework of a EU-granted project on the implications of the introduction of automatic milking on dairy farms. Some seven research institutes and six industrial companies from six countries joined their expertise and experience in order to facilitate a widespread adoption of automatic milking without undesirable side effects. This book reflects the knowledge on automatic milking generated all over the world in the last few years. Its contents can therefore be regarded as the present state of knowledge in the field of automatic milking, for a better understanding."

Available in PDF, EPUB and Kindle. Book excerpt: This is the Second Edition of a well-received book that reflects a fresh, integrated coverage of the concepts and scientific measurement of stress and welfare of animals including humans. This book explains the basic biological principles of coping with many forms of adversity. The major part of this work is devoted to explaining scientifically usable concepts in stress and welfare. A wide range of welfare indicators are highlighted in detail with examples being drawn from man and other species. The necessity for combining information from disciplines is emphasized with a one-health, one-welfare approach. This information forms the basis for a synthesis of new ideas. Among the issues covered are: - How brain and body systems regulate using feelings, physiological responses, behaviour and responses to pathology - Limits to adaptation - Assessing positive and negative welfare during both short-term and long-term situations - Ethical problems and suggested solutions A proper assessment of animal welfare is essential to take informed decisions about what is morally acceptable in terms of practice and in the development of a more effective legislation. This work encapsulates a very wide body of literature on scientific aspects of animal welfare and will thus prove a valuable asset for animal welfare scientists, psychologists, students and teachers of all forms of biology, behaviour, medicine, veterinary medicine and animal usage.

Download or read book Devil in the Milk written by Keith Woodford and published by Chelsea Green Publishing. This book was released on 2009-03-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking work is the first internationally published book to examine the link between a protein in the milk we drink and a range of serious illnesses, including heart disease, Type 1 diabetes, autism, and schizophrenia. These health problems are linked to a tiny protein fragment that is formed when we digest A1 beta-casein, a milk protein produced by many cows in the United States and northern European countries. Milk that contains A1 beta-casein is commonly known as A1 milk; milk that does not is called A2. All milk was once A2, until a genetic mutation occurred some thousands of years ago in some European cattle. A2 milk remains high in herds in much of Asia, Africa, and parts of Southern Europe. A1 milk is common in the United States, New Zealand, Australia, and Europe. In Devil in the Milk, Keith Woodford brings together the evidence published in more than 100 scientific papers. He examines the population studies that look at the link between consumption of A1 milk and the incidence of heart disease and Type 1 diabetes; he explains the science that underpins the A1/A2 hypothesis; and he examines the research undertaken with animals and humans. The evidence is compelling: We should be switching to A2 milk. A2 milk from selected cows is now marketed in parts of the U.S., and it is possible to convert a herd of cows producing A1 milk to cows producing A2 milk. This is an amazing story, one that is not just about the health issues surrounding A1 milk, but also about how scientific evidence can be molded and withheld by vested interests, and how consumer choices are influenced by the interests of corporate business.

Book excerpt: Milk has played a major contribution to the human diet in many different countries across the world since the dawn of time. The dairy cow was domesticated over 6000 years ago, she was the object of worship in the Middle East 2000 years before Christ, and milk and milk products are mentioned more than 50 times in the Bible. Milk and dairy products have become a major part of the human diet in many countries. It is not surprising therefore, that over many years considerable attention has been paid to improving the quality of milk. We have worked to improve the yield, the compositional quality and the hygienic quality, and have striven to minimise the level of contaminants which can find access to this, perhaps our most natural, unrefined and highly nutritious foodstuff. The chain of people involved in the milk industry extends from milk production-farmers, veterinarians and farm advisors-through transport to processing-quality controllers, manufacturers-and on to retailers, legislators, nutritionists, dairy educators and consumers. All will be interested in the quality parameters of milk which are reg ularly measured for commercial reasons, for trade, for legal requirements and for reasons of nutrition.
