Available in PDF, EPUB and Kindle. Book excerpt: One central aspect in milk production is the removal of the milk by the milking machine. In the present study the regulatory background of milk secretion and milk removal were intensively studied. The focus of interest was the interaction between dairy cow physiology and milking technology. A study on the interaction between the teat anatomy, teat functionality and milk flow profiles showed that the teat anatomy and the vacuum required to open the teat canal could partly explain quarter specific milk flow characteristics. In various experiments the effects of milking routines on oxytocin release, milk ejection and milking performance were investigated. Minimal mechanical impulses on the teat were sufficient to induce oxytocin release and to start the milk ejection. An individually adjusted pre-stimulation according to the actual degree of udder filling improved the milk flow rate and reduced the vacuum load to the teat. At the end of milking a quarter specific removal of teat cups reduced quarter specific machine-on time by approximately 20 %. Automatic milking systems (AMS) differ considerably from conventional systems. The adaptation during the changeover from conventional to automatic milking was studied in cows with and without previous experience in AMS. The heart rate during the first visits to the AMS was remarkably elevated in the latter group and the milk yield was reduced by 15 % due to the changeover. Unexperienced cows entered the AMS voluntarily at day 12 after the changeover. The adaptation capacity between individuals differed and was related to the adrenal cortex sensitivity. Experienced cows immediately visited the AMS voluntarily without human intervention. Furthermore the heart rate was not elevated during their first AMS visits after the changeover. The milk production and the milk fat content were reduced when milking intervals were prolonged while protein and lactose contents as well as somatic cell counts were not affected. These relationships.

This book was released on 2011 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current experiments were conducted to look at the impact of differing pre-milking routines on milking time parameters, milk quality and oxytocin profiles. All experiments were performed on Holstein cows milked 3X daily and producing 13-16 Kg/milking. Lag times of 0, 60, 90, 120 and 240 s along with forestripping or not forestripping were applied to 786 Holstein cows. Cows in early to mid-lactation had the highest milk yield in the first 2 min when lag time was 60 s and forestripping was included; however, lag time or forestripping had no impact on unit on-time for early to mid-lactation cows. The combination of forestripping with lag times of 90 and 120 s increased the amount of milk harvested in the first 2 min to>60% of the total and of milk and lag times beyond 60 s reduced milking unit on-time for late-lactation cows independent of forestripping. The quantity and quality of foremilk was analyzed to evaluate the relationship between foremilk and harvested milk plate loop count (PLC) and somatic cell count (SCC). The SCC and PLC of foremilk were not good predictors of the SCC and PLC in the harvested milk fraction. The foremilk represents 0.12% of the total milk harvested and the somatic cells and bacteria found in the foremilk represent

Download or read book Dairy Microbiology Handbook written by Richard K. Robinson and published by John Wiley & Sons. This book was released on 2005-03-11 with total page 781 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world, milk and milk products are indispensable components of the food chain. Not only do individual consumers use liquid milk for beverages and cooking, but food manufacturers use vast quantities of milk powder, concentrated milks, butter, and cream as raw materials for further processing. Effective quality assurance in the dairy industry is needed now more than ever. This completely revised and expanded Third Edition of Dairy Microbiology Handbook, comprising both Volume I: Microbiology of Milk and Volume II: Microbiology of Milk Products, updates the discipline’s authoritative text with the latest safety research, guidelines, and information. Pathogens have become a major issue in dairy manufacturing. Escheria coli is a concern, and milk-borne strains of Mycobacterium avium sub-sp. paratuberculosis have been identified as a possible cause of Crohn’s disease. Even little-known parasites like Cryptosporidium have caused disease outbreaks. Consequently, a hazard analysis of selected control/critical points (HACCP) in any manufacturing process has become essential to prevent the contamination of food. This volume also: -Discusses new diagnostic techniques that allow a pathogen to be detected in a retail sample in a matter of hours rather than days -Provides thorough coverage of dairy microbiology principles as well as practical applications -Includes the latest developments in dairy starter cultures and genetic engineering techniques -Offers completely updated standards for Good Manufacturing Practice Quality control and product development managers, microbiologists, dairy scientists, engineers, and graduate students will find the Third Edition of Dairy Microbiology Handbook to be a vital resource.

Download or read book Milk Quality written by F. Harding and published by Springer. This book was released on 2013-12-14 with total page 178 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book The Use of Drugs in Food Animals written by National Research Council and published by National Academies Press. This book was released on 1999-01-12 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of drugs in food animal production has resulted in benefits throughout the food industry; however, their use has also raised public health safety concerns. The Use of Drugs in Food Animals provides an overview of why and how drugs are used in the major food-producing animal industriesâ€"poultry, dairy, beef, swine, and aquaculture. The volume discusses the prevalence of human pathogens in foods of animal origin. It also addresses the transfer of resistance in animal microbes to human pathogens and the resulting risk of human disease. The committee offers analysis and insight into these areas: Monitoring of drug residues. The book provides a brief overview of how the FDA and USDA monitor drug residues in foods of animal origin and describes quality assurance programs initiated by the poultry, dairy, beef, and swine industries. Antibiotic resistance. The committee reports what is known about this controversial problem and its potential effect on human health. The volume also looks at how drug use may be minimized with new approaches in genetics, nutrition, and animal management.
