Available in PDF, EPUB and Kindle. Book excerpt: Adequate trace mineral status is important in beef cow/calf and replacement heifer systems because trace minerals play vital roles in reproduction, immunity and growth. Many experiments have investigated the use of a trace mineral injection containing Cu, Mn, Se and Zn (TMI) on growth and immunity of beef cattle. However, very few have investigated TMI use on reproductive performance. Therefore, five experiments, a two year cow/calf experiment, and four replacement heifer experiments were designed to investigate the use of a TMI on reproductive performance of cows and heifers, calf growth and trace mineral status of cows, heifers, and calves. The use of the TMI at pre-calving and pre-breeding did not consistently improve reproductive performance of heifers and cows with good trace mineral statuses that were receiving supplemental trace minerals. There were no differences (P ≥ 0.36) in the AI pregnancy rate [48 and 38% control (CON) vs 44 and 39% TMI, year 1 and year 2, respectively] or overall pregnancy rate (93 and 93 % CON vs 93 and 90% TMI, year 1 and year 2, respectively) of cows receiving a TMI when compared to control cows during the two year trial. In experiment 1 beef heifers (Angus ́Hereford ́Simmental) were bred to fixed time AI, TMI heifers had increased overall pregnancy rates (83 vs 92%, CON vs TMI, respectively; P = 0.02). In experiment 2 beef heifers were AI bred to synchronization response, TMI had no effect (78 vs 83%, CON vs TMI, respectively, P = 0.46). Conception rates to AI and overall pregnancy were not affected by TMI use in two experiments using Black Angus beef heifers being developed in a dry lot fed adequate trace minerals in a total mixed ration. Growth of suckling calves measured as birth weight, average daily gain, actual weaning weight, and 205 d adjusted weight were not influenced by TMI. However, trace mineral status of all groups of cattle were increased with use of TMI. In heifers liver Cu and Se were increased (P

Ryan and published by . This book was released on 2014 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of studies were conducted to determine the effect of supplemental trace mineral source on growth performance, morbidity, and trace mineral status in growing beef cattle. The first experiment evaluated supplemental trace minerals from sulfate, organic, or hydroxy sources on growth performance and morbidity. Crossbreed beef calves were assigned to 1 of 3 treatments consisting of supplemental zinc (360 mg/d), copper (125 mg/d), and manganese (200 mg/d) from inorganic, organic, or hydroxy sources fed daily over a 42 to 45-d backgrounding phase. After removal of chronic and dead calves from the data set, trace mineral source had no effect on final or intermediate weights (P > 0.55) or average daily gain (P = 0.51). For all calves, dietary treatments had no effect on any morbidity measurements (P ≥ 0.53). Overall, trace mineral source had no effect on total weight gain, average daily gain, or morbidity during the receiving phase in shipping stressed cattle. A second experiment was conducted to study the effect of trace mineral source on trace mineral status, superoxide dismutase activity, and performance in beef heifers fed diets high in sulfur. Crossbreed heifers were stratified into 3 treatments consisting of 1) no supplemental trace minerals; 2) supplemental copper (55 mg/d), zinc (165 mg/d), and manganese (110 mg/d) from sulfate sources; or 3) supplemental zinc, copper, and manganese at isolevels to treatment 2 from hydroxy sources fed daily over a 55-d trial. Final and intermediate weights (P = 0.73), average daily gain (P = 0.70), and plasma copper and zinc concentrations (P ≥ 0.37) were not affected by treatment. Liver copper concentrations on d 55 were greater for the sulfate treatment (P > 0.004) compared to control and hydroxy treatments, however, liver zinc concentrations were not affected (P > 0.29). Treatment had no effect on ( P ≥ 0.36) on total- or manganese-superoxide dismutase activity, however, a day effect (P ≥ 0.002) was observed. Overall, trace mineral source had no effect on growth performance, plasma mineral concentration, liver zinc concentrations, or superoxide dismutase activity. However, liver copper concentrations on d 55 were affected by trace mineral source.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Our objective was to evaluate the effects of pre- and post-partum bolus injections of a trace mineral solution on beef cow reproductive performance, body weight (BW) change, and body condition score (BCS) change and on performance of suckling calves. Mature beef cows (n = 460; initial BW = 497± 89 kg, initial BCS = 5.4± 0.74) were stratified by BCS, parity, and predicted calving date and assigned randomly to 1 of 2 treatments: 1) subcutaneous trace mineral (TM) injection containing 15 mg/mL Cu, 5 mg/mL Se, 10 mg/mL Mn, and 60 mg/mL Zn or 2) subcutaneous injection of physiological saline (SA). Injections were administered to cows (1 mL / 90 kg BW) 105 days before the first projected calving date and again 30 days before fixed-time AI. Calves received the same treatment as their dams and were injected (1 mL / 45 kg BW) at birth and again at 71± 21 days of age. Cows grazed native pastures for the duration of the study; trace mineral supplements and white salt were available to all cattle ad libitum before and during the study. Ovulation was synchronized using a 5-d CO-Synch + CIDR protocol and cows were inseminated 60 to 64 hours after CIDR removal. Cows were exposed to fertile bulls for natural-service breeding 10 days after AI for 35 to 50 days. Conception to AI and final pregnancy rate were assessed 36 days after AI with ultrasound and 120 days after AI via rectal palpation. Change in BW and BCS from initiation of the study to calving and from AI to weaning did not differ (P [equal to or greater than] 0.15) between TM and SA cows. Conversely, TM cows had greater (P = 0.04) BCS increase than SA cows between calving and AI. Calf BW at birth, ADG, and age-adjusted weaning BW did not differ (P [equal to or greater than] 0.36) between treatments. Proportion of cows with estrus cycles 17 and 8 days before ovulation synchronization was similar (P [equal to or greater than] 0.51) between treatments. Conception to AI was greater (P = 0.05) for cows receiving TM (60.2%) than for cows receiving SA (51.2%); however, overall pregnancy did not differ (P = 0.24) between treatments and averaged 92%. Under the conditions of our study, pre- and post-partum TM injections improved conception to fixed-time AI by beef cows.
Book Synopsis Trace elements in animal production systems by : P. Schlegel
Download or read book Trace elements in animal production systems written by P. Schlegel and published by BRILL. This book was released on 2023-08-28 with total page 347 pages. 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."

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.

Download or read book The Mineral Nutrition of Livestock written by Eric John Underwood and published by Oxford University Press, USA. This book was released on 2001 with total page 0 pages. 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
