TL;DR: The effects of water supplementation of chelated trace minerals (CTM) on growth performance, apparent total tract digestibility (ATTD) of minerals, and some blood metabolites, TM, and antioxidant enzyme values in African ostriches were investigated from 8 to 12 months of age as mentioned in this paper.
Abstract: The effects of water supplementation of chelated trace minerals (CTM, which is named Bonzaplex designed with chelate compounds technology) on growth performance, apparent total tract digestibility (ATTD) of minerals, and some blood metabolites, TM, and antioxidant enzyme values in African ostriches were investigated from 8 to 12 months of age. A total of 20 8-month-old ostriches (five birds in five replicate pens) was randomly allocated into one of the following four treatments: (1) control (basal diet + tap water), (2) low CTM (basal diet +100 mg/bird/day CTM powder in tap water), (3) medium CTM (basal diet +1 g/bird/day CTM powder in tap water), and (4) high CTM (basal diet +2 g/bird/day CTM powder in tap water). Compared with control, medium CTM improved (P < 0.05) daily weight gain and ATTD of phosphorous, zinc, and copper in 12-month-old ostriches. Furthermore, the feed conversion ratio was lower, and ATTD of magnesium was higher in the medium- and high-CTM groups than that in the control group (P < 0.05). At the end of the trial, ostriches receiving high-CTM treatment exhibited the lower (P < 0.05) serum triglyceride and very low-density lipoprotein cholesterol concentrations and higher copper levels compared to those of the control treatment. Supplementation of higher amounts of CTM (medium and high CTM) also increased the activity of serum superoxide dismutase (P < 0.05). No differences were detected for other blood parameters including glucose, total protein, albumin, cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, iron, magnesium, and glutathione peroxidase values. In conclusion, supplementation of CTM at the level of 1 g/bird/day to the drinking water can be recommended for improving growth performance, mineral absorption, and antioxidant status of ostriches fed diets containing the recommended levels of inorganic TM.

TL;DR: In this article, the effect of oils and HVCO on minerals absorption was carried out on 25 male rats, weighing approximately 150–200 g. The results showed that minerals absorption in rats given with dietary oils is significantly lower than the control group (51.79% for calcium and 42.34% for magnesium).
Abstract: Objective: The objective of this study was to investigate the effect of coconut oil (virgin coconut oil; VCO), corn oil, palm oil, and hydrolyzed VCO (HVCO) on minerals (calcium and magnesium) absorption in rats.Methods: The oils used were corn oil, palm oil, VCO, and HVCO. VCO hydrolysis was done using lipase from Rhizomucor miehei (active on sn-1,3 position). The effect of oils and HVCO on minerals absorption was carried out on 25 male rats, weighing approximately 150–200 g. Rats were housed in air-conditioned room at 22–25°C, under 12-light/dark cycle, fed on basal diet and tap water ad libitum. After 1-week acclimatization, rats were given oils and HVCO for 21 days. The effect of oils on the minerals absorption were determined over the 4-day metabolic balance study. Mineral concentrations in diet, feces, urine, and serum were measured using atomic absorption spectrometry. Minerals absorption are expressed as apparent minerals absorption, apparent minerals absorption rate, and apparent minerals balance.Results: Calcium absorption in rats given with VCO, corn oil, palm oil, and HVCO is 47.09%, 45.46%, 44.48%, and 49.33%, respectively, whereas, magnesium absorption in rats given with VCO, corn oil, palm oil, and HVCO is 34.87%, 32.08%, 29.39%, and 37.11%, respectively. The results of this study show that minerals absorption in rats given with dietary oils is significantly lower than the control group (51.79% for calcium and 42.34% for magnesium). Mineral absorption in rats given with HVCO results in the highest rate of all rats given with the other oils tested.Conclusion: Corn oil and palm oil, which belong to the long chain triglycerides oil, lower calcium, and magnesium absorption more significantly than VCO as a medium chain triglyceride oil does. HVCO results in significantly higher calcium and magnesium absorption compared to non-HVCO.

TL;DR: It has been confirmed that AGH-Ringer, manufactured with vitamin C as a substrate, is a fertilizer with excellent efficacy that increases growth and harvest simultaneously, solving the existing problems of chemical fertilizers such as sedimentation and lack of mineral absorptivity in nutrient solution systems.
Abstract: Mineral fertilizers are expensive and last only a relatively short time. Proper handling of fertilizers has a direct impact on crop quality and profitability. Currently, straight fertilizers are divided into types, A and B, based on the fertilizer’s sedimentation properties when mixed. Therefore, to solve these flaws, we developed a vitamin C-substrate organo-mineral fertilizer, AGH-Ringer. This study consisted of a fertilizer equivalency test, which lasted 15 weeks of soil cultivation in a farm field, using lettuce (Lactuca sativa L., ‘Jeok Chi Ma’) with AGH-Ringer as a test fertilizer. This fertilizer was based on powder compound-type fertilizer r-Ringer and manufactured by chelating essential minerals with a vitamin C substrate to have NPK contents in a ratio of 18.9:14:4.0. In the onsite evaluation, the superiority of AGH-Ringer was demonstrated through an effect of growth stimulation in both aerial and rhizosphere parts of the plants at suitable soil temperatures. This fertilizer also increased yield, even in inadequate low-temperature conditions. In addition, AGH-Ringer increased the absorption and bioavailability of minerals in lettuce leaves at harvest. The mineral absorption ability showed a uniform pattern during the entire harvest period. It has been confirmed that AGH-Ringer, manufactured with vitamin C as a substrate, is a fertilizer with excellent efficacy that increases growth and harvest simultaneously, solving the existing problems of chemical fertilizers such as sedimentation and lack of mineral absorptivity in nutrient solution systems.

TL;DR: It is concluded that consumption of a high-fat diet rich in SFA adversely affected bone health, but inulin supplementation in such a diet diminishes this negative effect.
Abstract: Consumption of a high-fat diet, rich in SFA, causes deterioration of bone properties. Some studies suggest that feeding inulin to animals may increase mineral absorption and positively affect bone quality; however, these studies have been carried out only on rodents fed a standard diet. The primary objective of this study was to determine the effect of inulin on bone health of pigs (using it as an animal model for humans) fed a high-fat diet rich in SFA, having an unbalanced ratio of lysine:metabolisable energy. It was hypothesised that inulin reduces the negative effects of such a diet on bone health. At 50 d of age, twenty-one pigs were randomly allotted to three groups: the control (C) group fed a standard diet, and two experimental (T and TI) groups fed a high-fat diet rich in SFA. Moreover, TI pigs consumed an extra inulin supply (7 % of daily feed intake). After 10 weeks, whole-body bone mineral content (P=0·0054) and bone mineral density (P=0·0322) were higher in pigs of groups TI and C compared with those of group T. Femur bone mineral density was highest in pigs in group C, lower in group TI and lowest in group T (P=0·001). Femurs of pigs in groups TI and C had similar, but higher, maximum strength compared with femurs of pigs in group T (P=0·0082). In conclusion, consumption of a high-fat diet rich in SFA adversely affected bone health, but inulin supplementation in such a diet diminishes this negative effect.

TL;DR: In this paper, the effect of germination of soybean and sesame seeds on the bioavailability of minerals of complementary foods was investigated using rats, and formulated diets were significantly higher (p<0.05) in protein, fat and moisture content and lower in carbohydrate and crude fibre than in control.
Abstract: The effect of germination of soybean and sesame seeds on the bioavailability of minerals of complementary foods was investigated using rats. Formulations of complementary diets 1 to 4 were produced from sweet potato, soybean and sesame flours at a ratio of 60:30:10, respectively. Formulated diets were significantly higher (p<0.05) in protein, fat and moisture content and lower in carbohydrate and crude fibre than in control. Diet 4 was significantly higher (p<0.05) in minerals (Ca, Zn and Fe) content than in control. The formulated diets were generally low in phytate and oxalate contents, while phytate content was much lower in the diets from germinated flour blends. Anti-nutritional factor (ANF): mineral molar ratio suggested good mineral absorption from the formulated diets. Mineral content of the tissues of rats fed with the formulated diets indicated good absorption within the rats; rats fed with the germinated flour blends had significantly higher (p<0.05) zinc, iron and calcium contents of tissues when compared. Diet 4 consistently received better rating among the samples. Key words: Complementary food, sweet-potato, germination, anti-nutrient, micronutrient.

TL;DR: A low dietary supplementation of OLE has no effect on the digestibility and retention of major nutrients, although some minor negative effects on mineral digestibility can be present.
Abstract: It is widely accepted that olive (Olea europaea L.) polyphenols (OP) have many favourable properties (e.g. antioxidative, antimicrobial, antifungal). OP can improve the growth and nutrient digestibility of animals via affecting digestion and health, even though they could negatively affect the mineral absorption by forming insoluble complexes with minerals in the intestine. In the present study, the effects of a dietary olive leaves extract (OLE) on nutrient digestibility in pigs were studied. Twenty-four weaned castrated male piglets were fed a no supplemented (C) or a supplemented diet with three different levels of OLE (O1, O2 and O3: 3.84 mg, 38.4 mg, 96 mg hydroxytyrosol equivalents/day, respectively). Retention and apparent total tract digestibility (ATTD) of dry matter (DM), crude protein (CP), crude fat (CF), organic matter (OM), nitrogen free extract (NFE), ash, neutral (NDF) and acid detergent fibres (ADF), gross energy (GE), Ca, P, Mg, Fe, Cu, Zn, K and Na were measured. Results showed that OLE lowered the retention of Fe and K, and revealed a numerical tendency to lower the retention of Cu and ATTD of Fe and Cu. In conclusion, a low dietary supplementation of OLE has no effect on the digestibility and retention of major nutrients, although some minor negative effects on mineral digestibility can be present.

TL;DR: The deficiency or overfeeding of minerals are cause of many problems in body. as discussed by the authors stated that the animals should be provided adequate amount of vitamins and minerals in all stages of life.
Abstract: Mineral feeding is very important for dairy animals. The deficiency or overfeeding of minerals are cause of many problems in body. Minerals are important for growth of calves and clean and more milk production by lactating animals. Animals are provided minerals through food, mineral mixture and mineral blocks. Ca is responsible for development of bones and its function. Iron containing enzymes are worked as immune system in body. In male animals reproductive performance are affected by Cu deficiency. Selenium is responsible for development of immune system and antioxidant status. Zinc directly affects semen volume and its other important parameters. Manganese is a important part of enzymes responsible for digestion of carbohydrate, fat and protein. Iodine is responsible for activity of thyroid gland. The ratio of vitamin and minerals should be maintained. The animals should provided adequate amount of minerals in all stages of life.
