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.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient utilization of feed protein by cattle, because of its impact on economics and the environment, is a major concern for animal nutritionists and producers. Ruminants play an important role in food production (milk and meat) and are major sources of protein for human livelihoods. Two experiments were conducted to assess the value of guanidinoacetic acid (GAA) with or without methionine (Met) on nitrogen retention, methionine flux, and methylation reactions in cattle. As well, a study was conducted to investigate the effectiveness of 2 ruminally protected methionine sources for lactating dairy cows. Another study evaluated effects of abomasal infusions of casein on dairy cattle production. The first experiment examined the effect of abomasal infusions of GAA (0, 10, 20, 30, or 40 g/d GAA) combined with either 0 or 12 g/d of methionine on creatine synthesis and plasma homocysteine concentrations in 6 ruminally cannulated Holstein heifers (520 kg initial body weight). This study demonstrated that plasma creatine was increased by GAA supplementation. Plasma homocysteine was not affected by GAA supplementation when heifers received 12 g/d methionine, but it was increased when 30 or 40 g/d of GAA was supplemented without methionine (GAA-linear x Met, P = 0.003). This experiment demonstrated that post-ruminal GAA supplementation increased creatine supply to cattle and spares arginine utilization. In the second study, effects of GAA supplementation on nitrogen retention and methionine flux were evaluated in 7 ruminally cannulated Holstein steers (161 kg initial body weight) limit-fed a soybean hull-based diet. Treatments were provided abomasally and included 0 or 6 g/d of L- methionine and 0, 7.5, and 15 g/d of GAA. Steers received continuous abomasal infusions of an essential amino acid mixture devoid of methionine to ensure that no amino acid besides methionine limited animal performance, and energy was supplied by ruminal infusion of volatile fatty acids and abomasal infusion of glucose. Whole body methionine flux was measured using continuous jugular infusions of 1-13C-L- methionine and methyl-2H3-L- methionine. Nitrogen retention was elevated by methionine supplementation (P

Download or read book Recent Advances in Animal Nutrition written by W. Haresign and published by Elsevier. This book was released on 2013-10-22 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Advances in Animal Nutrition-1981 is a collection of papers that discusses the effects of dietary fat on milk composition, relating it to the biochemistry of fat synthesis in the mammary gland. The influence of concentrates on milk composition as well as the pattern and level of concentrate feeding on milk output are also covered. The book describes the need for better utilization of grass and grass products in dairy production, the mineral and trace element requirements of pigs; the importance of anion-cation balance in poultry diets and its effects on performance levels; and the selenium and cobalt requirements of ruminants. The problems of medicinal residues in animal products and the toxicological effects of aflatoxin residues in animal products are also considered. People involved in agriculture, dairy production and animal nutrition will find the book useful.

Download or read book Nutrient Requirements of Dairy Cattle written by National Research Council and published by National Academies Press. 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 Methionine and Methionine Analog Supplementation written by Johanna E. Plank and published by . This book was released on 2011 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Methionine (Met) is one of the first limiting amino acids (AA) for milk and milk protein production in many dairy diets. Before dietary Met can be utilized by the cow, it is first exposed to microbial degradation in the rumen. Met that bypasses ruminal degradation, is absorbed in the hindgut, and is available for metabolism by the cow is termed 'bioavailable' Met. Met flow to the hindgut can be increased by adding supplemental Met to the diet or by supporting microbial protein synthesis (MPS) and subsequently increasing the flow of microbial protein (MCP) to the small intestine. The majority of protein, 50 to 80%, that reaches the hindgut of ruminants comes from MCP, whose AA composition closely resembles that of milk. Two studies were conducted to better understand the effect of Met supplementation on Met bioavailability and the impact on MPS in the rumen. In the first study, Se substitution for Met was used to estimate the change in the flux of methionine at the mammary gland. This method was used to compare the bioavailability of five Met treatments: control, DL-Met, Smartamine (SMA), 2-hydroxy-4-(methylthio)-butanoic acid (HMB), the isopropyl ester of HMB (HMBi), and an experimental rumen protected supplement (ERPM). Met supplements were fed to twenty Holstein cows as a top dressing that provided 18g of Met derivative/d, in a truncated Latin square experiment. In the second study, the effect of supplementation of Met, from Met and Met analogs, on the synthesis of Met de novo versus the incorporation of preformed Met into MCP was determined by dosing 15NH3 and 13C-Met in batch cultures assigned to a randomized complete block experiment. Treatments consisted of control, 0.097% L-Met, 0.097% D-Met, 0.125% HMBi, 0.098% HMB, 0.250% HMBi (2xHMBi), 0.063% HMBi + 0.049% DL-Met (HMBi+MET), and 0.098% HMB + 0.039% isopropanol (HMB+ISO) and treatments were inoculated with faunated or defaunated inocula. Unless otherwise specified, treatments within experiments were equal molar. The calculated metabolizable Met flow in the first study for cows supplemented with DL-Met, SMA, HMB, HMBi, and ERPM was 42.4, 47.0, 52.8, 48.7, and 50.3 g/d respectively. Metabolizable Met estimates were adjusted for reduced DMI with HMBi supplementation (20.4 kg/d versus 21.9 kg/d for control, P
