The present study investigated the effect of a moderate substitution of inorganic mineral sources with chelated mineral sources from four weeks prior to parturition throughout lactation on sow and litter performance. In addition, the aims were to determine whether the mineral source and litter performance affect mineral status and accretion in piglets at birth and at weaning. Forty gestating sows in a commercial pig herd were selected and randomly assigned to two experimental groups, with part of the Cu, Mn, Zn and Fe content of the feed added as either an inorganic mineral source or a chelated mineral source. From each sow, one piglet was randomly selected at birth and at weaning for total body mineral analysis. Neither the performance of the sows and the piglets nor the total body mineral concentrations of the piglets at birth and at weaning were significantly different between the two diet groups (<i>P</i> > 0.05). Fe, Na and P content of piglets at birth were inversely correlated with birth weight (<i>r</i> = –0.447, <i>P</i> = 0.004 for Fe; <i>r</i> = –0.431, <i>P</i> = 0.005 for Na; <i>r</i> = –0.340, <i>P</i> = 0.032 for P). Daily accretion rate of K and Ca of piglets was positively correlated with piglet growth performance during the entire lactation period (<i>r</i> = 0.469, <i>P</i> = 0.008 for K; <i>r</i> = 0.581, <i>P</i> < 0.001 for Ca), and negatively correlated with number of liveborn piglets (<i>r</i> = –0.424, <i>P</i> = 0.014 for K, and <i>r</i> = –0.405, <i>P</i> = 0.027 for Ca). In conclusion, the study documented that partial substitution of inorganic minerals with a chelated mineral source failed to exert significant effects on performance and total body mineral concentrations. The importance of the influence of sow milk production on mineral body stores in piglets warrants further investigation.

Mineral Sources

Trace minerals are constituents of proteins and enzymes that are involved in a variety of metabolic processes, having functional implications in growth, development, reproduction and health. Chelated minerals, are minerals bound to organic ligands, usually amino acids, providing higher levels of bioavailability compared to conventional inorganic mineral sources. In the present study, we investigated the effect of partial substitution of inorganic mineral sources with chelated minerals in sows’ diets, on three important reproductive parameters, the number of liveborn and weaned piglets and the wean-to-first service interval, in three Greek farrow-to-finish herds. Before initiation of the study the sows were on diets supplemented with 15 mg/kg feed Cu (from CuSO4), 125 mg/kg Zn (from ZnO) and 40 mg/kg Mn (from MnO). After exiting the farrowing facilities they were offered diets in which 93.3%, 36.0% and 62.5% of the supplemented Cu, Zn and Mn, respectively, originated from commercially available chelated minerals. For the last farrowing on inorganic minerals diet and the subsequent one or two (for 35.0% and 65.0% of the studied sows, respectively) on chelated minerals, each sow’s reproductive data (total number of parities, number of liveborn and weaned piglets and wean-to-first service interval) were recorded. The reproductive parameters, before and after the supplementation with chelated minerals, were compared in two mixed-effect linear regression models, for the number of liveborn and weaned piglets, and in a zero inflated negative binomial model for the weaning-to-first service interval. There was an improvement of the mean number of liveborn piglets after partial substitution of inorganic source of minerals with chelated minerals by almost half a piglet (P=0.015), whereas there was no effect on the total number of weaned piglets (P=0.15) and the wean-to-first service interval (P=0.65). The increase in the number of liveborn piglets may be directly attributed to improved embryo survival due to increased bioavailability of the organic minerals or indirectly to the beneficial effect of chelated minerals on sows’ hoof health, locomotor ability, feed intake and body condition.

Introduction. Trends in developing Ukraine’s metallurgy in the context of using its mineral raw base indicate prospects for mining hematite quartzite deposits. Problem Statement. The problem of producing high-quality hematite ore concentrates is associated with the fact that aggregates of martite, goethite, marshallit quartz, and other low hard minerals can be easily reground while crushing and grinding. This results in increased content of fine particles (slimes), which decreases selectivity of separating ore and non-metallic minerals. One of the ways to solve this problem is gentle ore grinding Purpose. Developing a technology of dry and wet concentration for hematite quartzite from Kryvyi Rih Iron Ore Basin. Materials and Methods. While conducting the research, a set of methods are used including generalization of research data; chemical and mineral analysis of ore and concentration products prior to and after concentrating by magnetite and gravitation methods; mathematical modeling of processes; technological testing in laboratory and industrial conditions. Results. Magnetic and gravitation separation is used for hematite ore concentration. Sintering ore with Fe content of 55.1% and concentrates of 62.32-64.69% Fe have been produced from hematite ore. Iron extraction in marketable products makes up 73.6-80.49%. Conclusions. There have been developed technologies for dry and wet concentration for hematite quartzites of Kryvyi Rih Iron Ore Basin. For the first time, magnetic separation has been suggested to be used for hematite ore concentration. This has enabled producing concentrates with an iron content over 64.0%, decreasing ore grinding front by at least 40% as compared with the initial one, and reducing operation and capital expenses by over 30%.

We measured total body insulin-mediated glucose uptake, carbohydrate oxidation, storage (nonoxidative disposal), muscle glycogen synthase activity, and muscle glucose 6-phosphate (G-6-P) content in response to five levels of insulinemia (means 16, 52, 152, 573, and 5,550 microU/ml) in 16 male glucose-tolerant volunteers. Insulin dissociation constants (KDs) for disposal, storage, and synthase activity (but not for oxidation) are coincident, suggesting that storage via glycogen synthesis could be a major determinant of glucose disposal. Increases in glucose disposal were associated with decreases in muscle G-6-P concentration. These data suggest that the principal control over carbohydrate disposal is exerted after G-6-P. The coincidence of insulin sensitivities for disposal, storage, and synthase activity suggest that storage via glycogen synthesis could be a major determinant of glucose disposal.

In this study, the responses of 20 different bean genotypes (13 pole and 7 dwarf) to salt (NaCl) stress at 0 mM, 25 mM and 50 mM were investigated. Salt application was performed together with irrigation water in the same time every day during 4 days. In the study, which was prepared according to randomized plot design with 3 replications, the plants were grown in the pots containing peat-perlite in a ratio of 2:1 under climatic conditions of 23±2°C. Root dry matter, root fresh and dry weight and some nutrient contents (Phosphorus-P, Copper-Cu, Zinc-Zn, Manganese-Mn, Iron-Fe and Magnesium-Mg) were investigated in order to determine salinity tolerance in bean genotypes. The data obtained from the study revealed that salt stress responds differently in both genotypes and applications. When the average of applications of 25 mM and 50 mM salt stress was examined, it was found that while root fresh and dry weight, root dry matter (%) and Fe content increased compared to control group, Mn and P content decreased. Among the genotypes exposed to salt stress, while four genotypes [two pole (numbered as 13 and 19) and two dwarf (numbered as 8 and 11)] were determined to be tolerant to salt, 3 genotypes [one pole (numbered as 14) and two dwarf (numbered as 18 and 20)] were evaluated as sensitive.

Abstract Objectives It has been estimated that 90 mg of iron (Fe) is retained by a ∼600 g term placenta to support placental needs, but this value is based on limited data. While there has been an increase in studies evaluating placental Fe content (p[Fe]), there is also substantial variability in published values. Our aims were to characterize p[Fe] in pregnant women at risk of Fe deficiency and to identify determinants of p[Fe]. Methods Placentae were collected at 39.8 ± 1.2 weeks of gestation from 132 neonates born to teens carrying singletons (≤18 y) and at 35.3 ± 2.4 weeks of gestation from 101 neonates born to 48 women carrying multiples (20–46 y). Maternal and cord blood samples were collected and maternal and neonatal Fe status indicators (hemoglobin, serum ferritin (SF), transferrin receptor (sTfR), serum Fe, total body Fe (TBI)) and regulatory hormones (erythropoietin (EPO), hepcidin) were measured. Inductively coupled plasma-mass spectrometry was used to measure p[Fe]. Results Mean placental weight per fetus was 290 ± 74 g in the multiples and 619 ± 149 g in the teens (p &lt; 0.001). Mean p[Fe] was 23 mg per placenta [95%CI 15–33] in the multiples and 40 mg per placenta [95%CI 31–51] in the teens (p = 0.03). Mean μg of Fe per g of placental wet tissue did not differ between the two cohorts. Maternal anemia had opposite effects on p[Fe] in the two cohorts. In women carrying multiples, mean μg of Fe per g of placenta was higher in anemic compared to non-anemic women (p = 0.02). In contrast, mean μg of Fe per g of placenta was lower in anemic compared to non-anemic teens (p = 0.04). These divergent observations were supported by observed associations between p[Fe] and maternal Fe status markers at delivery. In women carrying multiples, low maternal Fe status [lower SF (p = 0.002) and lower TBI (p = 0.01)] was associated with higher μg of Fe per g of placenta, while in teens, improved Fe status [lower sTfR (p = 0.03) and higher TBI (p = 0.03)] was associated with higher μg of Fe per g of placenta. Conclusions These human data show that p[Fe] is significantly associated with maternal Fe status but determinants of p[Fe] differ between adult women and teens who may still be growing. Using current methodology, the average p[Fe] was found to be ∼50% lower than previously estimated. More data are needed to characterize p[Fe] and understand maternal and neonatal determinants of p[Fe]. Funding Sources The USDA and Gerber Foundation.

1. The total body calcium (Expt 1) of litter-mate male rats given a diet adequate in phosphorus and high (0·74%) or low (0·13%) in Ca from the age of 3 weeks was determined after 21, 48 and 60 weeks on the diet. In Expt 2, the ash content of ten groups of bones from 10-week-old rats given these same diets for 7 weeks was studied to ascertain whether all groups were equally affected by the difference in dietary Ca level. Four groups of bones, i.e. skull and mandibles, vertebras, the shafts and the ends of long bones, were consequently chosen for examination in Expt 3 where their growth and composition were studied in rats given the Ca diets for 24, 48 or 60 weeks from the age of 3 weeks.2. Total body Ca (Expt 1), expressed as g Ca or as a percentage of the net body-weight or of net dry, fat-free carcass weight, was always significantly higher in rats given the higher level of Ca. The dietary effect was greatest after 21 weeks.3. The higher level of dietary Ca led to a highly significant increase in the weight of the dry, fat-free bone and in the percentage ash content of all ten bone groups after 7 weeks (Expt 2). The greater treatment differences in ash content occurred with the less well mineralized bones.4. In Expt 3, irrespective of diet, the four groups of bones developed at different rates. In rats given the diets for 24 weeks or longer, the vertebras and the shafts of long bones showed the greatest proportional increase in weight of dry, fat-free bone and ash relative to the corresponding values for 3-week-old rats; the greatest change in percentage ash content occurred in the ends of the long bones.5. Increasing the level of Ca in the diet increased the weight of the dry, fat-free bone and its ash content. The effect of diet decreased with increasing time on the diets, in general persisting most strongly in the skull and mandibles and declining most rapidly in the ends of the long bones. The percentage Ca and P content of the bone ash was only slightly affected by diet and, except for the Ca in the ash of vertebras, significant differences were only found in the composition of the ash of bones from 27-week-old rats.

AbstractA multidisciplinary mineralogical, geochemical and biomarker study of Indus Fan sediments cored during International Ocean Discovery Program (IODP) Expedition 355 to the Laxmi Basin was carried out to define the different compositional signatures of sand, silt and clay. Upper Pliocene – lower Pleistocene turbidites from sites U1456 and U1457 were selected as the best candidates for this study. The integrated dataset presented here was obtained by coupling traditional and innovative bulk-sediment and single-mineral techniques on the same samples. Turbiditic deposits mostly consist of medium to fine silt, including rich and diverse heavy-mineral assemblages. Such a fine grain size forced us to push the limits of high-resolution quantitative heavy-mineral analysis down to as low as 5 μm. Heavy-mineral analysis allowed us to establish a Himalayan origin of the detritus in the studied turbidites. Heavy-mineral concentrations are higher in channel-fill than in overbank deposits. Mineralogical and geochemical data concur in revealing that fast-settling ultradense minerals such as zircon are preferentially concentrated in channel-fill deposits, whereas the top of overbank deposits are notably enriched with slow-settling platy phyllosilicates. Biomarker analysis represents a most suitable complementary technique that is able to investigate the provenance signature of the finer sediment fraction, largely consisting of clay. This technique allowed us to identify a largely terrigenous origin of organic matter at Site U1456 and an open marine origin at Site U1457. The latter site lies closer to the Laxmi Ridge, where thermal maturity increases with depth to reach the early oil window (127°C at c. 320 m below the seafloor).
