A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to cereal-soybean meal based diets on the mineral content in tibia (Ca, P, Fe, Mg, Cd, Zn). Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Supplemental phytase increased the mineral levels in tibia. A statistically significant increase was observed for Fe (P < 0.024) and Mg (P < 0.024), but not for Ca, P, Cd and Zn contents in tibia. In the case of Fe and Mg contents significant cereal × phytase interactions were also observed (P < 0.036 and 0.002, respectively). Cereals influenced the contents of Fe (P < 0.0001), Mg (P < 0.0001), Cd (P < 0.0001) and Zn (P < 0.003) while dietary calcium levels affected only calcium content (P < 0.008).

Lack of calcium and phosphorus minerals in bones can cause decreased bone density, bone becomes brittle and at risk of osteoporosis. The purpose of this study was to analyze changes in mineral levels and functional groups in tibia osteoporosis because of ovariectomy and were treated with a nano-calcium phosphate diet. In this research, dietary formulations containing nano-calcium phosphate made. Diets given to animal models of osteoporosis rats caused by ovariectomy with the aim to balance the mineral content in the rats tibia. Dietary formulations were made of 3 types based on their calcium content, namely the first diet (D1), the second diet (D2) and the third diet (D3) each having a total calcium content of 1.0x, 1.5x and 2.0x normal body needs. Characterization and analysis of mineral content in the tibia bone using Atomic Absorption Spectroscopy (AAS) and Ultraviolet-Visible (UV−vis), while the characterization and analysis of functional groups with Fourier Transform Infrared Spectroscopy (FTIR). Based on the data obtained, ovariectomy rats showed signs of osteoporosis with decreased levels of calcium in the tibia and a decrease in phosphate ion function groups at 9 weeks since ovariectomy. The results of dietary treatment showed that postovariectomy osteoporosis rats fed a diet with a total calcium content of 1.5x normal body needs (D2) and gave more effective and efficient results compared to diets containing 1.0x (D1) and 2.0x (D3) total calcium normal body needs.

Egg producers primarily use oyster shell or limestone as supplemental sources of dietary calcium. This study was conducted to investigate the efficiencies of limestone (CaCo3 ) and oyster shell as calcium sources in the diets of laying hens. Ninety, 58 weeks old Golden Comet Hubbard laying birds were randomly allotted to three treatments of three replicates. Each replicate had 10 birds per replicate. Three different rations were formulated for the study. To include Diet 1 as the control, a diet with bone meal (46%) and oyster shell (54%). Diet 2 had oyster shell and bone meal supplying 82% and 18% of the dietary calcium while Diet 3 had 82% and 18% of the dietary calcium supplied by limestone and bone meal respectively. Feed and water were provided ad-libitum. The parameters measured include: Feed intake (g/d); Hen day production (%); Efficiency of feed utilization (kg); Egg and shell weight (g); Bone weight (g); Ash content of bone (%) and Calcium content of bone (%). The study lasted eight weeks. Results revealed that birds on Diet1 had the highest value for feed intake (0.11 g/d) that differed significantly (P<0.05) from the value (0.10 g/d) obtained for Diet 2 and 3 Hen day production for birds on Diet 2 (57.04) and Diet 3 (56.30) were similar, but differed significantly (P<0.05) from birds on Diet 1 (65.44). Efficiency of feed utilization (EFU kg) was not significantly affected by the dietary treatments as birds on Diet1 had the lowest EFU value (1.80) while birds on Diet 2 had the highest EFU value (2.05). A higher percent of eggs within 50-59g were laid by birds on Diet 3, while eggs of 60g and above were laid by birds on Diet 1 (62 g), significant (p<0.05) variations occurred among treatment means for these egg grade. Egg shell percent was not significant, same trend was observed for bone weight. The effect of dietary treatment on the ash content of bones were similar for birds on Diet 2 and 3, except for bone humerus, however, significant (p<0.05) variation occurred between birds on diets 1 and other two Diets. Calcium contents of the different bones were differed significantly (p<0.05) with birds on diet 3 recording the highest values for all bone investigated. It can be concluded from this study that Limestone can replace oyster shell as a source of calcium in the diet of laying hens without deleterious effect.

A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on nitrogen, calcium, total and phytate phosphorus excretion and retention. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Nutrient intake, excretion and retention were determined in the first three days of the 2nd and 3rd week of trial. The increasing phytase level resulted in reducing phytate phosphorus excretion and increasing its retention. Significant differences were obtained only in the 2nd week (excretion P &lt; 0.024 and retention P &lt; 0.044). Phytase supplementation significantly influenced total phosphorus excretion in the 3rd week (P &lt; 0.048) and retention in the 2nd week (P &lt; 0.015). The effects of 500 and 1 000 PU/kg were not statistically different from each other. No significant influence of phytase supplementation on nitrogen and calcium excretion and retention was observed. &nbsp;

Within the context of maximizing the use of dietary phosphorus, a growing-finishing pig study was conducted to determine the optimal total dietary calcium (Ca) to digestible phosphorus (dP) ratio and to verify the possibility of mineral phosphate removal during the finishing period on growth performance and mineral status. The potential for replacing chemical and mechanical bone properties by dual energy X-ray absorptiometry (DXA) measures on non-dissected feet was also verified. Three Ca to dP ratios (2.2:1, 2.5:1 and 2.8:1) within two dP levels (P+, P–) were fed during 91 days to 84 pigs. The grower and finisher P+ diets contained 3.0 and 2.4 and P– diets contained 2.5 and 1.7 g dP/kg, respectively. Growth performance and blood serum mineral content were independent of treatments, except that 2.2:1 impaired finisher feed conversion ratio compared to 2.5:1 and 2.8:1. Urinary P concentration increased by 37% in 2.2:1 compared to 2.5:1 and 2.8:1. Maximal load on bone and DXA mineral density were reduced in 2.2:1 compared to 2.8:1. Bone ash and volumetric density were reduced in 2.2:1 and 2.5:1 compared to 2.8:1. Diet P– reduced bone ash, maximal load, volumetric density and DXA bone mineral content and density. No interaction was observed between Ca and dP level. Therefore, 2.2:1 was insufficient for an efficient metabolic use of P, 2.5:1 was sufficient to maximize growth performance and 2.8:1 further improved bone mineralization. Increasing dietary Ca did not impair bone zinc content. Diets P– without supplemented mineral phosphates during the finisher period resulted, per pig, in a decrease of its use by 65% and of the calculated P excretion by 41%, without impaired growth performance. Finally, DXA data responded to dietary treatments as did labor intensive chemical and mechanical bone properties.

AbstractThe aim of this study was to develop an in vitro re-mineralization model in human serum. For this purpose a commercially produced demineralized human bone matrix (DBM) was incubated in samples of human serum pools obtained from two physiologically different groups. The first group consisted of young males and the second of older females. After incubation periods of 4 and 7days at 37°C, changes in the levels of calcium and inorganic phosphate content of the serum and DBM samples were measured. The results of the study showed that the change in mineral content of serum and DBM samples in both study groups was statistically significant. The decrease in serum calcium content and increase in DBM inorganic phosphate content were significant in the young group for longer incubation times. In the older group, both serum calcium and inorganic phosphate decreased and DBM mineral content increased for the same incubation time. When the two physiological groups were compared, statistically significant differences were identified for changes in mineral levels in both serum and the DBM samples. These data indicate that the mineral content of human serum decreases and that of DBM increases when these two materials are incubated together. These changes provide evidence for the re-mineralization of DBM. The model described here could also detect a difference in re-mineralization capability between two different groups of human sera.

Data obtained over three growing years were examined with principal component analysis (PCA) to study how cherry quality was affected by pre-harvest mineral status in leaves, fruitlets and orchard growing factors. Higher foliar levels of calcium were correlated with lower levels of pitting and pebbling in stored cherries, however there was no relationship with these disorders and fruitlet calcium content. Temperature and leaf size were associated with pebbling and pitting levels in stored cherries. Leaf and fruitlet mineral content are not the only factors to be considered in understanding fruit quality; environmental effects and management techniques should also be considered.

Recent epidemiological and animal studies have led to the hypothesis that low dietary calcium intakes contribute to obesity. Here, we evaluated whether calcium influenced the body weight of normal-weight and obese rodents. All experiments involved female C57BL/6J mice or Sprague-Dawley rats fed normal- or high-energy-density diets (3.8 or 4.7 kcal/g). Calcium intake was manipulated by allowing mice to drink sweetened 30 mM CaCl2 solution or feeding mice and rats diets differing in calcium content (0.2%, 0.6%, or 1.8% Ca2+). Blood samples were taken from rats to confirm that the diets had their intended effects on metabolism. There were no effects of the calcium manipulations on energy intake, body weight, or carcass fat content and no simple relation between calciotropic hormones and body weight. One experiment found a significant decrease in body weight gain of lean and obese rats fed the 1.8% Ca2+ diet, but we suspect that this was due to forced consumption of the unpalatable diet, reducing growth. These studies provide little support for the hypothesis that dietary calcium contributes to the etiology or maintenance of obesity.

Three cultivars of Brassica (Westar, Brassica napus; Tobin, B. rapa; Cutlass, B. juncea) were grown in four locations in 4 successive years, with duplicate samples taken from each treatment. Harvested seed was hexane-extracted, ground and analyzed for mineral content. The average contents (mg kg−1) were: Ca, 0.64; P, 1.12; Mg, 0.56%; Cu, 6.2; Zn, 46; Fe, 188; and Mn, 55. Values for Westar and Tobin were generally similar but Cutlass contained less Ca, Mg, Fe and Mn and more Cu and Zn (P < 0.01). Locations affected all mineral levels. One location produced samples lower in Ca, P, Cu and Mn but higher in Zn than the other locations (P < 0.01). Year-to-year variability was of minor consequence.
