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.

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: 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

Download or read book Effects of Supplemental Trace Mineral Concentration and Source on Liver and Serum Trace Mineral Concentrations Health and Performance of Newly Received Calves from New Mexico Ranches written by Margaret Elizabeth Garcia and published by . This book was released on 2015 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two studies were conducted at the Clayton Livestock Research Center to evaluate Cu, Mn, and Zn source, as well as dietary inclusion to evaluate concentration and source on liver and serum repletion, on health, and overall performance. Mineral treatments were formulated to provide supplemental Cu, Mn, and Zn from inorganic sources at either 100 (INO1X) or 300% of recommended concentrations (INO3X); or a 50:50 blend of inorganic and organic sources of Cu, Mn, and Zn offered at the same two concentrations (OR1X or OR3X). Experiment 1. Eighteen crossbred steers (initial BW 185 ± 24.5 kg) were subjected to a 60-d depletion period and given ad libitum access to cornstalks with no mineral supplement. Then used in a completely randomized design with a 2 x 2 factorial arrangement of treatments to test the effects of supplemental Cu, Mn, and Zn concentration and source on liver and serum repletion. The main effect of source on liver Mn or Zn concentrations did not differ (P >̲ 0.12). Liver Cu concentration tended (P = 0.09) to be greater at d 30 and was greater (P 0.01) by d 60 in steers fed inorganic sources. Conversely, when cattle were placed on a higher plane of nutrition (NEm = 0.44 versus 1.86 Mcal/kg) during the repletion period (ADG = 1.4 kg BW · steer-1 · d-1), liver size may have increased, thus diluting liver mineral concentrations per unit of liver mass. Experiment 2. Five hundred and twenty-seven crossbred cattle (initial BW 255 ± 14.5 kg) originated from New Mexico ranches were used in a randomized block design with a 2 x 2 factorial design for treatments. No interaction effect (P 0.16) of mineral source by concentration was detected for BW, ADG, or G:F. However cattle fed inorganic mineral tended (P = 0.06) to have higher ADG than cattle fed organic mineral for d 29 - 56 as well as d 0 - 56. Source x concentration interaction was observed for liver Cu concentrations at d 28 (P = 0.01). Serum Zn concentrations were greater at d 28 and d 56 (P = 0.004).
