Available in PDF, EPUB and Kindle. Book excerpt: Dairy products have always constituted an essential component in the Mediterranean diet. In addition to their nutritional values, they represent also a part of the cultural heritage of the people. Prospects for a sustainable dairy sector in the Mediterranean, preconditions for its development and the future consumers' demand were some of the issues covered by the papers presented at the EAAP - CIHEAM - FAO Mediterranean symposium. It was organised by the Tunisian Office for Livestock and Pastures and the National Agronomic Research Institute and sustained by the Government of Tunisia, FAO, ICAR and CIRVAL. Over 280 participants from 25 countries participated. The symposium identified a variety of technically viable and scientifically sound policy options and defined the main fields requiring further scientific research and the development of new sustainable technologies. The available technologies to address intensive, semi intensive and extensive production systems and the existing institutional framework (research, education, extension systems, organisation of the sector), although requiring continuous adjustments and improvements, have proved to be in a position to meet a variety of demands and challenges. In this respect, the Symposium called for an increase in research for the semi-intensive farming systems in the South and emerging issues resulting from changes in agricultural policies in the North. It emphasised the importance of producers1 associations as representatives of the interests of the sector and partners in the overall dialogue on policy matters and in the identification of research needs. The Symposium confirmed the wish and capacity of the dairy sector in the Region to contribute to the sustainable rural development, to the creation of new employment opportunities and to the reasonable and harmonious management of the natural resources.

This book was released on 2011-05-02 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 30 years, modelling has been an important method for integrating, in a flexible, comprehensive and widely applicable way, basic knowledge and biological concepts on digestion and metabolism in farm animals. The purpose of this book is to present the 'state of art' in this area. The chapters are written by leading teams and researchers in this field of study, mainly from Europe, North America and Australasia. Considerable progress has been made in topics dealing with: modelling methods, feeding behaviour, digestion and metabolic processes in ruminants and monogastric animals. This progress is clearly illustrated by the emergence of a new paradigm in animal nutrition, which has moved from the aim to cover the requirements of the animal to explaining and predicting the responses of the animals to diets (e.g., productivity and efficiency, impact on quality of products, environmental aspects, health and well-being). In this book several chapters illustrate that through empirical models, meta-analysis is an efficient tool to synthesize information gathered over recent decades. In addition, compared with other books on modelling farm animal nutrition, two new aspects received particular attention: expanding knowledge of the individual animal to understanding the functioning and management of herds, and the consideration of the environmental impact of animal production. This book is a valuable source of information for researchers, nutritionists, advisors, and graduate students who want to have up-to-date and concise information on mathematical modelling applied to farm animals.

Available in PDF, EPUB and Kindle. Book excerpt: Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavours, and colours. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut Red Delicious apples whether by hand or mechanical methods. This book presents the recent research from around the world in this field.

Available in PDF, EPUB and Kindle. Book excerpt: Agricultural English is a collection of essays on the English of Agriculture. The approach is a linguistic one: the different aspects of the English used in the field of agriculture (agricultural practices, agricultural systems) and in some fields related to agriculture (agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, zoology) are analysed from a morphological (combination, derivation), syntactical (nominal phrases, verbal phrases), lexical and lexicographical, semantic (homonymy, semantic fields, synonymy, terminology), pragmatic (academic discourse, idiom, metaphor), etymological (etymon, Latin heritage), and contrastive (English–Croatian, English–French, English–German, English–Romanian, Romanian–English) points of view. The book will appeal to agriculturists, animal breeders, professors, researchers, students, and translators from Croatian-, English-, French-, German-, and Romanian-speaking countries, active in their own countries or abroad. The types of academic readership it would appeal to include academic teaching staff, researchers and students in the fields of agriculture and related fields – agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, and zoology.

Book excerpt: Breeds of livestock on British farms are changing constantly. New breeds emerge, foreign breeds are imported, while some native breeds lose popularity and become endangered. More than half the native breeds in Britain are rare and potentially threatened with extinction, yet they are an integral part of our history and heritage. Many of them are distinctive animals, and some possess special characteristics that could be of value to the livestock industry. A return to more traditional values was seen towards the end of the twentieth century, and this will serve to enhance the value of native breeds.

This book was released on 2015-09-22 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les resultats obtenus ont mis en evidence l'existence d'un stress thermique qui se manifeste entre les mois de juin et septembre. Ce stress est tres severe dans les regions de Kebili et de Tozeur au sud du pays ou les valeurs THI depassent 78. Mais il est intense pour le reste du pays avec des valeurs THI variant entre 72 et 78. Le THI a significativement affecte la production, l'ingestion et les parametres physiologiques de la vache laitiere. En effet, lorsque le THI passe de 68 a 78, la production chute de 21 % (4 kg) et l'ingestion de la matiere seche de 9,6 % (1,73 kg). En outre le THI presente des correlations negatives avec la production laitiere (-0,76) et avec l'ingestion (-0,24). Pour une meme variation de THI (68 a 78), la temperature rectale et les rythmes cardiaque et respiratoire ont augmente de 0,5 C, 6 battements et 5 inspirations/mn respectivement. Cet effet de stress thermique est plus prononce a 13: 00 h ou on assiste a une elevation des valeurs des differents parametres physiologiques mesures. En outre, la concentration plasmatique en cortisol est passee de 21,75 a 23,5 nmol/l, alors que celle de la thyroxine libre a chute de 15,5 a 14,5 pmol/l."
