Available in PDF, EPUB and Kindle. Book excerpt: This book is an up to date reference work covering all aspects of macro and trace element nutrition in farm livestock. Sufficient information is given on metabolism, functions and interactions to explain why needs, feeds and imbalances are not always easy to define or anticipate. The major emphasis is on the mineral nutrition of ruminant livestock since they are most likely to be affected by imbalances but where pigs and poultry are the more vulnerable, extensive coverage of the non-ruminant is given. This new edition of a highly successful text has been thoroughly revised and significantly expanded. Many chapters have been extensively updated and several chapters on new topics introduced. * Calcium, phosphorus, sodium and potassium are now treated separately * Over 40 new figures are presented, and extensive use made oftables to summarise important data * Chapters on trace elements have been drastically revised * Claims for enhanced availability for new chelated sources arecritically reviewed * Completely new chapters focus on: The unique need of the ruminant for elemental sulphur Occasionally beneficial elements and essentially toxic elements The improved conduct and interpretation of supplementation trials

Available in PDF, EPUB and Kindle. Book excerpt: "This book deals with trace elements, such as cobalt, copper, iron, manganese, selenium and zinc which are essential to modern animal nutrition, but are increasingly detrimental to soil and water quality in today's globalized production. The goal in finding a sustainable balance between trace element use in animal nutrition and its impact on the environment is addressed by focussing on the following questions: - What is the trace element flow on farm, regional or national scale and which tools are available to influence the flow? - What are today's and future soil and water quality in regards to trace minerals? - What are the trace mineral loading limits in soil and water from a health and legal standpoint? - Which technologies exist to modify slurry trace element contents? - What is today's knowledge on quantitative and qualitative trace element requirements and recommended supplementation for ruminants, swine, poultry, fish and crustaceans? - What is trace element bioavailability and how can it be determined? - To which extent are trace minerals related to immune response? - What are the future issues to be addressed in trace element nutrition? This book contains the peer-reviewed papers of the first International Symposium on Trace Elements in Animal Production Systems. It is a valuable resource for researchers and professionals in the life sciences of animal nutrition, soil and water quality, for actors in the feed industry and policy making."

Available in PDF, EPUB and Kindle. Book excerpt: Experiments were designed to study the effects of Cu, Zn, and Mn supplementation on production, gene expression of trace mineral transporters expressed in the milk fat globular membrane (MFGM), milk fatty acid (FA) profiles, digestibility, and fecal bacteria relative abundance in lactating dairy cattle. In experiment 1, 30 Holstein cows were fed diets devoid of supplemental Cu, Zn, and Mn (basal diet provided 8, 41, and 41mg/kg, respectively) for 30 d and were then split into three treatment groups: one group remained on the unsupplemented diet; the second and third groups were fed a diet supplemented with Cu, Zn and Mn from sulfates (assayed total dietary concentrations = 17, 60, and 55mg/kg, respectively) or glycinates (assayed total dietary concentrations = 20, 66, and 58mg/kg, respectively) for 30 d. Milk yield (averaged 29.2 kg/d), DMI (averaged 3.55% of BW or 22.5 kg/d) as a percent of BW, and milk components were not affected by treatment. Feeding supplemental minerals decreased iso-15:0, anteiso-15:0, iso-17:0, and 16:1+anteiso-17:0 branched-chain fatty acids (FA) and tended to increase trans-10 18:1 as percentages of total FA in milk fat. Trans-10 18:1 was greater (0.76 vs 0.50%) for cows fed sulfate minerals compared to glycinate sources. Gene expression (via qPCR) of metallothionein (1.51 vs 0.77 2(-delta Ct)) in MFGM were greater for multiparous cows than primiparous. Expression of a zinc transporter, ZIP8, was greater (3.37 vs 2.06 and 2.65 2(-delta Ct)) for cows not fed supplemental minerals compared to cows fed sulfate and glycinate sources, respectively. In experiment 2, Eighteen multiparous cows were used in a split-plot replicated Latin square with two 28 d periods to evaluate the effects of Cu, Zn, and Mn source (sulfates or hydroxy; Micronutrients Inc., Indianapolis, IN) and dietary neutral detergent fiber (NDF) source (forage-based control diet = 26% NDF vs byproduct = 36%) on total-tract nutrient digestibility, mineral balance, and gene expression of trace mineral transporters in the MFGM. During the entire experiment (56 d) cows remained on the same fiber treatment but source of supplemental trace mineral was different for each 28 d period so all cows were exposed to both mineral treatments. During each of the two 28 d periods cows were fed no supplemental Cu, Zn, or Mn for 16 d followed by 12 d of feeding supplemental Cu, Zn, and Mn from either sulfates or hydroxy sources. Basal Cu, Zn, and Mn concentrations for the control diet were 9, 30, and 38mg/kg, respectively; while basal concentrations were 11, 50, and 47mg/kg, respectively for the byproduct diet. Supplemental concentrations of Cu, Zn, and Mn fed were approximately 9, 30, and 30mg/kg, respectively. Treatment had no effect on DMI (averaged 24.2 kg/d) or milk production (34.9 kg/g). No mineral source x fiber interactions were observed for production measures or macronutrient digestibility; however apparent Cu balance and Cu retention was increased for cows fed the control diet with hydroxy minerals compared to the control diet with sulfate minerals (+11 vs -3 mg/d), but retention of Cu was decreased for the byproduct diet when cows were fed hydroxy minerals compared to sulfates (-5 vs +29 mg/d). Cows fed the byproduct diet had decreased DM digestibility (65.9 vs 70.2%), OM digestibility (67.4 vs 71.7%), CP digestibility (58.8 vs 62.1%) and starch intake (4.3 vs 8.8kg), and increased starch digestibility (97.5 vs 96.3%), NDF intake (8.6 vs 6.0kg) and NDF digestibility (50.5 vs 44.4%) compared with cows fed the control treatment. The control diet had increased TDN concentration (70.2 vs 65.3%) compared to the byproduct diet. Measured NDF digestibility and TDN treatment effects were consistent regardless of the method used to determine NDF. Multiple (>12) milk FA concentrations were affected by fiber source and mineral source. In experiment 3, 24 cows were fed diets devoid of supplemental Cu, Zn, and Mn for a 16 d preliminary phase (basal diet provided 9, 29, and 32mg/kg of Cu, Zn, and Mn, respectively), and then were randomly assigned to one of three treatment diets (n=8 cows/treatment): supplemental Cu, Zn, and Mn from sulfate mineral; or glycinate minerals; or Cu and Mn sulfate with glycinate Zn. Assayed total dietary concentrations were approximately 21, 73, and 72 mg/kg for Cu, Zn, and Mn, respectively. Body weight, milk production (averaged 38.8 kg/d), DMI (averaged 25.8 kg/d), and analyzed milk components were not affected by treatment. Fecal DNA was extracted, amplified using the 16S rRNA gene to quantify total bacteria, and microbial populations were sequenced to compare populations between treatments. Relative abundance of phyla Spirochaetes, family Spirochaetaceae, genus Treponema, and uncultured or other treponema species were less abundant for cows fed Cu and Mn sulfate with glycinate Zn compared to those fed sulfates, but were similar to cows fed glycinate mineral sources, and responses for cows fed either exclusive glycinate mineral or sulfate mineral treatments were similar.

Download or read book Nutrient Requirements of Beef Cattle written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-06-16 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. The cattle industry has undergone considerable changes since the seventh revised edition was published in 2000 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eighth revised edition of the Nutrient Requirements of Beef Cattle builds on the previous editions. A great deal of new research has been published during the past 14 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of beef in all stages of life, this volume includes new information about phosphorus and sulfur contents; a review of nutritional and feeding strategies to minimize nutrient losses in manure and reduce greenhouse gas production; a discussion of the effect of feeding on the nutritional quality and food safety of beef; new information about nutrient metabolism and utilization; new information on feed additives that alter rumen metabolism and postabsorptive metabolism; and future areas of needed research. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.

Download or read book Mineral Supplements for Beef Cattle written by Chad Shawn Hale and published by . This book was released on 2001 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beef cattle require a number of dietary mineral elements for normal bodily maintenance, growth, and reproduction. Minerals that are required in relatively large amounts are called major or macro elements. Those needed in small amounts are classified as micro, minor, or trace minerals. These terms, however, have no relationship to the metabolic importance of a mineral in the diet. A trace mineral can be as essential to the health and performance of an animal as a major mineral. The major minerals include calcium, phosphorus, magnesium, potassium, sodium, chlorine and sulfur. Among those needed in trace amounts are iron, zinc, manganese, copper, iodine, cobalt and selenium. This publication discusses the functions, animal requirements, and special considerations of these minerals.

Download or read book Effect of Mineral Supplementation on Reproductive Efficiency of Beef Cows written by Felipe Guirado Dantas and published by . This book was released on 2018 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive efficiency is the major component for an economically efficient cow/calf operation and can be influenced by a number of factors such as breed, age, health and nutrition. Among the components of the diet, trace minerals are hypothesized to have a major impact reproductive efficiency in beef cattle. In order to test this specific hypothesis, a study directly evaluating the success of reproductive performance in cows fed complexed trace minerals versus inorganic trace mineral was designed. In this study, 68 cows where equally divided into treatment (cows fed with complexed trace minerals) and control (cows fed with inorganic trace minerals) groups. The cows started being fed 30 days prior to AI (d -30). Twenty-eight days after AI (d 28), all cows where diagnosed for pregnancy and non-pregnant cows where removed from the experiment. Twenty-four days after pregnancy diagnosis (d 52), pregnant cows where submitted to ovum pick-up (OPU) and a second OPU was performed on d 67. Although pregnancy rates did not differ (P = 0.33) between treatment and control, cows fed with complexed trace minerals had increased oocyte recovery (P = 0.03), in vitro embryo production (P = 0.06) and more efficient in vitro embryo production (P = 0.06). In summary, the results from this experiment demonstrated that supplementation of beef cows with a complexed source of trace minerals improves reproductive efficiency when compared to cows fed inorganic source of trace minerals.
