Effects of normal and low calcium and phosphorus levels and 25-hydroxycholecalciferol supplementation on performance, serum antioxidant status, meat quality, and bone properties of broilers

Consequences of varying dietary calcium and phosphorus levels on lipid profile, antioxidant and immunity parameters of growing Egyptian geese

“…Related to the interaction among Ca and P levels effects, antioxidant indices levels were not significantly changed due to Ca and P interaction levels (p > .05). These results were partially agreement with Zhang et al (2020) who reported that serum concentrations of T-AOC and CAT were decreased by dietary Ca and P deficiencies without 25-OH-D 3 (Interaction, p < .05) and unaffected by dietary deficiencies of Ca and P with 25-OH-D 3 at 42 days of age. In the present study, antioxidant parameters (SOD, CAT and GSH) were elevated numerically at 0.85% Ca and 0.45% P interaction and 0.70% Ca and 0.45% P interaction.…”

“…Also, MDA levels were numerically decreased at interaction supplementation of these Ca and P levels. Dietary supplementation of 25-OH-D 3 decreased (p < .05) serum concentration of MDA in broilers (Zhang et al 2020). Oxidation of lipid is a fundamental indicator for poor meat quality and more rancidity%, moreover development of forbidden alterations in colours, flavour and odour (Gray et al 1996).…”

Effect of Feeding a High Calcium: Phosphorus Ratio, Phosphorous Deficient Diet on Hypophosphatemic Rickets Onset in Broilers

“…Low blood P concentration is an indication of hypophosphatemic rickets [8]. Consistent with our study, Li et al [26] and Zhang et al [10] reported that the serum P was decreased by dietary P deficiency. The primary reason for low serum P may be due to the high Ca:NPP ratio, as serum P levels were not affected when a balanced Ca:NPP ratio was maintained in a low-P diet [26].…”

“…The blood samples were transferred into tubes containing a coagulation promoting agent and maintained at room temperature for two hours, before centrifuging at 1000× g at 4 • C for 10 min for serum collection. Serum P was determined in duplicate via phosphomolybdic acid methodology using commercial kits (Zhongsheng Beikong Bio-technology and Science Inc., Beijing, China) [26] analyzed using a Beckman Coulter AU5800 unit (Beckman Coulter Inc.; Brea, CA, USA).…”

Effects of high-intensity interval training in more or less active mice on biomechanical, biophysical and biochemical bone parameters

“…For example, we have used a proper procedure for biomechanical assessment, but not gold standard method for biophysical analysis (dual-energy X-ray absorptiometry—DXA) and for fracture prediction (the high-resolution peripheral quantitative computed tomography—HR-pQCT) like suggested recently by Mikolajewicz et al 64 . Nevertheless, as shown by Tie et al 65 , the Archimedes ’Principle is an ancient and valid method for this purpose, and it have been used a lot nowadays 66 , 67 , but not always capturing small changes in bone size at specific locations. A final point to be discussed is that the present results were obtained with mice trained at light period, and therefore caution must be taken when interpreting and generalizing our findings to humans.…”
