This book was released on 2001-02-09 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This widely used reference has been updated and revamped to reflect the changing face of the dairy industry. New features allow users to pinpoint nutrient requirements more accurately for individual animals. The committee also provides guidance on how nutrient analysis of feed ingredients, insights into nutrient utilization by the animal, and formulation of diets to reduce environmental impacts can be applied to productive management decisions. The book includes a user-friendly computer program on a compact disk, accompanied by extensive context-sensitive "Help" options, to simulate the dynamic state of animals. The committee addresses important issues unique to dairy science-the dry or transition cow, udder edema, milk fever, low-fat milk, calf dehydration, and more. The also volume covers dry matter intake, including how to predict feed intake. It addresses the management of lactating dairy cows, utilization of fat in calf and lactation diets, and calf and heifer replacement nutrition. In addition, the many useful tables include updated nutrient composition for commonly used feedstuffs.

Download or read book INRA feeding system for ruminants written by INRA and published by BRILL. This book was released on 2023-11-27 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: The INRA Feeding System for Ruminants has been renewed to better address emerging challenges for animal nutrition: prevision of productive responses, product quality, animal health and emissions to the environment, in a larger extent of breeding contexts. The new system is mainly built from meta-analyses of large data bases, and modelling. The dietary supply model accounts for digestive interactions and flows of individual nutrients, so that feed values depend on the final ration. Animal requirements account for variability in metabolic efficiency. Various productive and non-productive animal responses to diets are quantified. This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas. The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins. Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes. Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.

It focuses on applications of nanotechnology in packaging and drying of dairy and meat products, nanofiltration use in the dairy industry, and whey processing and dairy encapsulation. In addition, this book will facilitate the necessary understanding of the different aspects and concerns with regard to the new technological advances that nanotechnologies are contributing to the dairy industry. It also addresses several of the challenges that are overcome by the continuing development of nanotechnology applications in the food and dairy industries. Nanotechnology has the potential to provide healthier, safer, and better tasting foods as well as improved food packaging. It will also play a major role in food safety and agricultural sustainability. Nanotechnology application in the food industry has also contributed to the exponential progress in research and new material formulations due to its unique physicochemical properties useful to a number of other fields.
Download or read book Use of Methionine Supplements to Enhance the Protein Fraction of Goat Milk written by Krista Lauren Jacobsen and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of dietary methionine supplements were studied using six lactating does (3 Saanen and 3 Alpine) all expressing alleles for low levels of alpha s1 casein (E/E or E/F) in a replicated Latin square design. Does were fed a basal diet composed of (as a proportion of total dry matter) 56.2% long alfalfa hay, 14.3% alfalfa pellets, and 29.5% concentrate ingredients. Methionine was fed either in the free form (not rumen protected) or rumen-protected to provide an additional 2.3 g methionine/doe daily. Other than effects on animal production performance, milk was analyzed for processing characteristics (rennet clotting time, firmness of rennet-induced gel, cheese yield and firmness), as well as proteomic profile to establish potential relationships between milk proteins, milk urea nitrogen, amino acid contents of plasma and milk, and milk fatty acid profile. Animal Production Results: Average daily milk yield and milk yield as a proportion of body weight (g milk/kg body weight) were improved relative to control by rumen-protected methionine in Saanens (p=0.03, both responses). Relative to control, plasma methionine increased with both supplements, but was only significant for the free-form treatment (p=0.05). Other amino acids (plasma and milk), urea nitrogen (plasma and milk), and content and yield of individual milk components were not affected by methionine supplementation, although a tendency was observed for increased yield of milk protein with methionine supplementation. Of the fatty acids measured in milk, concentrations of C9:0 and C11:0 were increased relative to control with the free-form methionine supplement in Saanens (p=0.02, each fatty acid). Rumen-protected methionine increased yield of C13:0 (p=0.04), compared to control. Yield of C15:0 was increased in Saanen milk with both the free-form (p=0.02) and rumen-protected (p=0.03) supplements, compared to control, and Alpines overall produced higher yields of C9:0 (p=0.04). Concentrations of C16:1 cis, C18:1 cis 11, C18:1 cis 13, and C22:5n3 were higher in Saanen milk while Alpine milk was higher in concentration of C18:2 cis 9 trans 11. Rumen-protected methionine tended to enhance daily yield of total casein; otherwise daily yields of individual caseins, as well as major whey proteins, were not affected by either treatment or breed. Milk Processing Results: Both rennet clotting time (p=0.02) and gel firmness (p=0.02) were improved by rumen-protected methionine, most notably among Saanens. Saanen milk tended to be higher in concentration of alpha s2 casein, alpha-lactalbumin, and lipoprotein lipase, but yields of these proteins did not differ from yields in Alpine milk. Mixed model selection revealed that increasing alpha s2 casein concentration improved rennet clotting time and cheese yield, whereas concentrations of C16:0 prolonged rennet clotting time. Milk urea nitrogen negatively impacted cheese firmness and yield, as well as concentrations of immune proteins in milk. The principal factors influencing concentrations of caseins and major whey proteins were plasma Group 1 amino acids (methionine, phenylalanine, tyrosine, tryptophan, and histidine) and plasma ornithine. Concentrations of butyrophilin and adipophilin were negatively influenced by concentrations of alpha s2 casein and positively by concentrations of kappa casein. Milk Proteomic Profile Results: Liquid chromatography tandem mass spectrometry analysis identified a total of 367 proteins in milk samples, with quantification achieved using intensity-based absolute quantification (iBAQ). Of the most frequently-detected proteins (i.e., in at least 12 out of 18 samples), the top primary function groups represented were immune/stress response (29.2% of the proteins), protein synthesis/folding (22.3%), transport/trafficking (16.9%), and lipid secretion/metabolism (6.9%). These results indicate that Saanens responded better than Alpines to methionine supplementation, and proportions of caseins, rather than concentration of milk protein alone, are important considerations when selecting goat milk intended for cheese production. The complete proteomic profile of whole goat milk contributes to a relatively sparse database. Knowledge of the types of proteins present in goat milk and their relative abundance can lead to the translation of their health promoting benefits.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
