Aim. To investigate the vitamin D status in highly productive cows during winter housing period and effect of cholecalciferol by various ways of vitamin D 3 injection to cows in last days of gestation and after calving. Methods. Enzyme-linked immunoassay, spectrophotometry. Results. It has been stated that intramuscular injection of cholecalciferol into cows caused increase of the vitamin D 3 active metabolite – 25-OHD 3 , calcium, phosphorus and magnesium levels together with decrease of alkaline phosphatase level in pre- and post-natal periods. Oral supplementation makes little infl uence on the studied blood parameters of cows. Conclusions. Extrabuccal administration and oral supplementation of cholecalciferol in winter housing period to high-yield cows in the last days of gestation and after calving is accompanied by increased levels of its metabolites and their effect on mineral metabolism in the postnatal period. The nature of these changes depends on the mode of vitamin D administration and the physiological state of the cows.

Background: Osteoporosis is a common age related problem especially in women, with a consequent increase in bone fragility and susceptibility to fracture. Apart from Calcium, another nutrient that plays an important role in the mineralization of skeleton in Vitamin D. Osteocalcin, which is produced primarily by osteoblasts during bone formation, is considered to be one of the markers for osteoporosis.Methods: 314 women above the age of 40 were included into the study. A thorough physical and clinical examination, assessment of vital parameters, anthropometry evaluation was done for all patients. Bone mineral density was calculated using central DXA osteodensitometer at lumbar spine L1-L4, hip and ultradistal radius (in some cases.). Blood samples were taken for the detection of ionized calcium, phosphorus, alkaline phosphatase, 25hydroxivitamin D (25 ODH) and serum parathyroid hormone (PTH) by chemiluminiscent assay. Bone markers such as osteocalcin were measured as required.Results: Out of the 314 women attending our OPD, 96 of them were diagnosed as having osteoporosis. 24 out of them had fragility fractures, mainly of the hip, and 82 had ostepenia. Elevated levels of calcium (8.96 mg/dl), parathyroid hormone (58.76 pg/ml) and osteocalcin (24.46 ng/ml) were observed. Vitamin D deficiency of ≤ 20 was seen in 59 (63%) of the cases, insufficient in 23 (24%) and only 12 (13%) of these women had normal Vitamin D levels.Conclusions: Osteocalcin is a promising marker for the detection of osteoporosis. There is a considerable Vitamin D deficiency among the women with osteoporosis, and it is under-treated. It is essential to provide Vitamin D supplementation to these women especially those who are at high risk for fragility fractures.

Organic phosphorus is poorly utilized by monogastric animals because they lack phytase, the enzyme that cleaves the ortho-phosphate groups from the phytate molecule. Diets fed to pigs are supplemented with inorganic P, and this can increase environmental pollution and diet costs. Sixty mixed sex, half-breed pigs, were used to evaluate the effect of increasing dietary levels of phytase (253, 759, 1265 and 1748 PU kg-1 feed) on animal performance as compared to a control without phytase but supplemented with dicalcium phosphate. Enzyme levels did not affect daily feed intake, food conversion, average daily weight gain, plasma P and Ca, calcium and phosphorus in bone ash, and the calcium/phosphorus ratio in the plasma and bones. A quadratic relationship between phytase levels and the percentages of P and Ca in bone ash was observed, reaching a maximum at the 880 and 879 PU levels, respectively. Animals fed diets containing phytase presented low plasma P values when compared to the control, but no effects were observed for the regression analysis. Using 759 PU phytase in rations containing corn, soybean bran and defatted rice bran for growing pigs can eliminate the use of traditional sources of P.

Abstract Context: Craniotabes in otherwise normal neonates has been regarded as physiological and left untreated. Objective: Our objective was to investigate the role of vitamin D deficiency in the development of craniotabes in normal neonates. Design and Setting: Newborn screening of craniotabes was conducted at the single largest obstetrical facility in Kyoto, Japan. Follow-up study at 1 month was conducted at Kyoto University Hospital. Subjects: A total of 1120 consecutive normal Japanese neonates born in May, 2006, through April, 2007, were included in the study. Main Outcome Measures: The incidence of craniotabes was scored each month. Neonates with craniotabes were followed up at 1 month with measurements of serum calcium, phosphorus, alkaline phosphatase (ALP), intact PTH, 25-OH vitamin D (25-OHD), urinary calcium, phosphorus, creatinine, and hand x-rays. Results: Craniotabes was present in 246 (22.0%) neonates, and the incidence had obvious seasonal variations, highest in April-May and lowest in November. At 1 month, infants with craniotabes had significantly higher serum ALP compared with normal neonates; 6.9% of them had elevated intact PTH over 60 pg/ml, and 37.3% had 25-OHD less than 10 ng/ml. When separately analyzed according to the method of feeding, 56.9% of breast-fed infants showed 25-OHD less than 10 ng/ml, whereas none of formula/mixed-fed infants did, and breast-fed infants had significantly higher serum PTH and ALP compared with formula/mixed-fed infants. Summary: These results suggest that craniotabes in normal neonates is associated with vitamin D deficiency in utero, and the deficiency persists at 1 month in many of them, especially when breast-fed.
