“…The bending moment was calculated according to the formula: bending moment = F × L/4, where F is the failure load, and L the length (m) between the two fulcrum points supporting the bone. It is expressed in N × m. This parameter was selected because of its great sensitivity to mineral nutrition in the pig [8,35,38,39].…”

“…L -1 and the intra-and inter-assay coefficients of variation were both near 5%. A modified radioimmunoassay kit (OstkPr, Oris, Gif-sur-Yvette, France) was used to determine osteocalcin, with purified bovine osteocalcin as the standard and tracer, rabbit antiserum to bovine osteocalcin, and an internal porcine standard [39]. Calcitriol was measured by a radioreceptor assay using a kit (Nichols Institute Diagnostics, San Juan Capistrano, USA) after extraction on modified C 18 OH columns.…”

“…The growing pig is a useful experimental model in which changes in bone and mineral metabolism caused by diets with varying mineral content may be investigated [8,31,37,39,45]. Clearly, it is much more feasible to work with young growing animals, whose calcium metabolism is very active, than to attempt such studies on children.…”

-Dairy products provide abundant, accessible calcium for humans, while some calcium sulfate-rich mineral waters could provide appreciable amounts of calcium. But there is little evidence that this calcium is as available as milk calcium for making bone. The availability of calcium was studied by monitoring bone parameters in 2-month-old pigs fed restricted amounts of calcium (70% RDA) for 2.5 months. The 3 main (≥ 50% Ca intake) Ca sources were either CaCO 3 or CaSO 4 or skim milk powder (29% of the diet). The bones of the pigs fed the "milk" diet had higher (P < 0.01) ash contents, breaking strength and density (DEXA) than those of the two others groups, in which the bone values were similar. Thus, the calcium provided by a diet containing milk appears to ensure better bone mineralization than do calcium salts included in a non-milk diet. The calcium restriction may have enhanced some milk properties to stimulate calcium absorption in these young, rapidly growing pigs.calcium availability / calcium sulfate / milk calcium / bones / pigs Résumé -Biodisponibilité comparée du calcium du lait, du sulfate et du carbonate de calcium pour la minéralisation osseuse: étude chez le porc. Le sulfate de calcium, dont certaines eaux minérales sont riches, est-il aussi bien utilisé pour la minéralisation osseuse que le calcium des produits laitiers ? Trois lots de 8 porcs, de 2 mois, recevaient pendant 2,5 mois, trois régimes dont au moins 50 % de l'apport calcique était fourni par CaSO 4 , CaCO 3 ou la poudre de lait. Bien que différents dans leur composition, les trois régimes étaient formulés pour avoir la même valeur nutritionnelle et leur teneur en Ca était restreinte (70 % des recommandations). Avec le régime « lait », les cendres, la résistance à la rupture et la densité minérale des os étaient supérieures à celles des deux autres groupes, non différents l'un de l'autre. L'analyse des paramètres circulants liés au métabolisme osseux (en particulier au collagène), des 3 groupes, exclut l'hypothèse d'un effet direct de la source Reprod. Nutr. Dev. 40 (2000) 49-61 49

At 45 days of age, 40 male Wistar rats were castrated, then randomly divided into four groups, S.C. injected for 60 days after surgery either with 17beta-estradiol (E) 10 microg/kg BW/48 hours, progesterone (P) 140 microg/kg BW/48 hours, dihydrotestosterone (D) 2 microg/kg BW/48 hours, E + P + D same doses, or solvent alone (CX). Ten other rats were sham-operated (SH) and used as controls. Animals were put in balance to determine Ca and phosphorus (Pi) intestinal apparent absorption (IA Ca, IA Pi) and urinary pyridinium crosslinks excretion. Plasma was collected for measurement of intact-parathyroid hormone (PTH), calcitonin (CT), insulin-like growth factor I (IGF-I), 1,25 dihydroxyvitamin D (1,25(OH)(2)D), Ca, and Pi. Orchidectomy induced marked seminal vesicles atrophy and increased plasma CT, PTH, and Ca concentrations. IA Ca was significantly higher in P rats, however, neither castration nor any other treatment had significant effects. Orchidectomy decreased femoral length, dry weight, and Ca content, whereas E or D given alone or together with P improved endochondral growth and enhanced femoral Ca content. Again, bone mineral density was lowered by orchidectomy and reestablished by both E and EPD, even above SH values, this effect being more important at the metaphyseal levels. Urinary pyridinium cross-links excretion and plasma osteocalcin concentrations were higher in the CX animals than in the controls. Although E and D given alone did reduce both biochemical turnover markers, they showed additive effect when given together (EPD). In conclusion, in the young castrated male rat, E was more efficient than D for preventing bone loss, the most important effect being induced by a combination of E+P+D.
