Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The goals of the modern dairy producer are much higher than those of past producers. Therefore, emphasis on vitamins and dietary supplements is required to ensure that dairy cows are healthy and are able to meet the high production demands placed upon them. This project is very much a part of this ultimate goal as it examines the effects two rumen-protected choline products have on the dry matter (DM) and nitrogen (N) disappearance in rumen digesta. In this experiment, 2 rumen-protected choline products, [ProCholine[TM] 50 (P-50), Probiotech, Inc., St-Eustache, QC, Canada; and Reashure®, Balchem Encapsulates, New Hampton, NY] were incubated in situ in 2 rumen cannulated cows. Dacron bags containing the product samples were placed into the rumen of each cow. Two bags per product (~ 2.5 g of product) per cow were removed at the same time intervals: 0, 2, 4, 6, 12, 24, and 48 hours. The material remaining in the bags after incubation were analyzed for DM (105oC oven overnight), N (Kjeldahl, strong acid method). DM analysis showed that Reashure® is a much more rumen-stable product, as its rate of disappearance was 1.15% per hour with a rumen degradation of 2.62% over 48 hours. ProCholine[TM] 50, however, had a 27.50% per hour disappearance and degraded 38.70% over 48 hours. Nitrogen analysis reaffirmed this trend: Reashure® had a 1.75%per hour rate of disappearance and a 12.54% degradation over 48 hours. Pro-Choline [TM] 50 had a 16.85% rate of disappearance and a 57.30% degradation over 48 hours.

Download or read book Supplementation of Rumen protected Forms of Methionine Betaine and Choline to Early Lactation Holstein Cows written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Methionine (Met) is frequently the first limiting amino acid or co-limiting with lysine in dairy rations, and Met metabolism is closely linked to that of betaine and choline. Methionine, betaine, and choline are all degraded by microbes in the rumen, so rumen-protected (RP) forms were used to perform two experiments. The objective of these experiments was to investigate the impact of supplementing RP forms of methionine, betaine, and choline to a Met-limited total mixed ration (TMR) on performance, metabolism and ruminal fermentation in early lactation Holstein cows. Experiment 1 utilized 80 lactating Holstein cows from 21 to 91 days in milk (DIM) that were fed a corn silage-based TMR formulated to meet National Research Council (2001) recommendations, except the Met content was limited (42 gD). One of four supplements was blended into the TMR to produce four dietary treatments: 1.) control, 2.) 20 gD RP-Met, 3.) 45 gD RP-betaine, and 4.) 40 gD RP-choline. Calcium salts of fatty acids were used to protect the RP-betaine and RP-choline supplements and were added to the control and RP-Met supplements so that equal amounts of fat were supplied to all treatments. Consequently, dry matter (DM) intake, body weight, and body condition score were not significantly different among treatments (P> 0.2). The treatment by parity interaction tended to be different (P = 0.06) for milk yield with 44.3 kgD produced in multiparous (MP) cows fed RP-choline compared to MP cows fed all other treatments (37.8, 40.0, and 38.7, respectively) while there were no differences among treatments in primiparous cows. Cows fed RP-met or RP-choline had higher milk crude protein yield than cows fed control or RP-betaine (P = 0.02). However, there were no differences in milk fat yield or milk urea nitrogen (P> 0.2). Experiment 2 utilized 4 dual-flow continuous culture fermentors (700 ml) to determine the effects of supplementation of rumen-protected forms.

Available in PDF, EPUB and Kindle. Book excerpt: With the dramatically rising sophistication of biological methods and products and the increasing use of recombinant DNA technology, now is an apt time to review the status of biotechnology in animal feeding. This book gives succinct yet comprehensive coverage of products of biotechnology and allied sciences used in animal feed and feeding industries. Particular emphasis is placed on: - Conservation and upgrading of feeds and feed components - Increasing the protein value of feeds - Antimicrobials - Microbial feed additives - Increasing the energy value of feeds. Moreover, increasing environmental concerns are reflected in chapters describing dietary products which may help to reduce environmental hazards from animal feeding enterprises. A discussion of social and legislative aspects relating to biotechnology and animal feeding rounds off this useful compilation of timely articles.

Download or read book Advanced Dairy Chemistry Volume 2 written by Paul L. H. McSweeney and published by Springer Nature. This book was released on 2020-12-08 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Advanced Dairy Chemistry series was first published in four volumes in the 1980s (under the title Developments in Dairy Chemistry) and revised in three volumes in the 1990s and 2000s. The series is the leading reference on dairy chemistry, providing in-depth coverage of milk proteins, lipids, lactose, water and minor constituents. Advanced Dairy Chemistry Volume 2: Lipids, Fourth Edition, is unique in the literature on milk lipids, a broad field that encompasses a diverse range of topics, including synthesis of fatty acids and acylglycerols, compounds associated with the milk fat fraction, analytical aspects, behavior of lipids during processing and their effect on product characteristics, product defects arising from lipolysis and oxidation of lipids, as well as nutritional significance of milk lipids. In the years since the publication of the third edition there have been significant developments in milk lipids and these are reflected in changes to this volume. Most topics included in the third edition are retained in the current edition, which has been updated; in some cases, new authors have given their perspective on certain topics. Chapters on nutritional significance of dairy lipids have been considerably revised. This authoritative work summarizes current knowledge on milk lipids and suggests areas for further work. It will be very valuable to dairy scientists, chemists and others working in dairy research or in the dairy industry.

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.
