Phosphorous Supplementation: Insights from Recent Research
Phosphorous Supplementation in Preterm or Low Birth Weight Infants
Phosphorous supplementation in preterm or low birth weight infants has been studied to assess its impact on various health outcomes. A systematic review and meta-analysis evaluated the effects of calcium or phosphorous supplementation compared to no supplementation in human milk-fed preterm or low birth weight infants. The findings indicated a reduction in osteopenia at 38 weeks, but no significant effects on weight, length, head circumference, alkaline phosphatase, serum calcium, or serum phosphorus at different follow-up periods. The certainty of the evidence was rated from very low to low, and no studies reported on mortality or neurodevelopment outcomes.
Phosphorous Supplements in Poultry and Livestock
Rock Phosphates for Growing Chicks
Research on the use of defluorinated rock phosphates as a phosphorous supplement for growing chicks has shown that the phosphorus from amorphous calcium meta phosphate is as available as that from tri-calcium phosphate. However, results have been inconsistent when using calcium meta phosphate, suggesting variability in the effectiveness of different phosphate sources.
Dietary Supplements in Pullets
A study on the effects of vitamin C and D supplementation in pullets found that while these vitamins did not significantly affect the deposition of phosphorus, iron, or vitamin C in eggs, certain combinations of vitamin C and D did enhance phosphorus deposition. This suggests that specific dietary combinations can optimize phosphorus levels in eggs, potentially benefiting consumer health.
Organic Phosphorus in Ewes
In anoestrous Farafra ewes, organic phosphorus supplementation significantly improved reproductive performance, including shorter intervals to oestrous resumption, increased antral follicle development, and higher pregnancy rates. This indicates that organic phosphorus can be beneficial in restoring ovarian activity and enhancing reproductive outcomes in livestock.
Phytase Supplementation in Animal Diets
Weaned Piglets
Supplementation with a novel 6-phytase in weaned piglets fed phosphorus-limiting diets significantly increased phosphorus and calcium availability, improved growth performance, and enhanced bone mineralization and density. This suggests that phytase can reduce the need for inorganic phosphorus supplements while maintaining animal health and performance.
Broilers
Phytase supplementation in broilers fed low-phosphorus diets improved growth performance, mineral digestibility, and bone properties. The addition of phytase, along with propionic acid and sodium citrate, further enhanced these effects, indicating that phytase can be a valuable supplement in poultry diets to optimize phosphorus utilization and reduce environmental phosphorus excretion .
Conclusion
Phosphorous supplementation, whether through direct dietary sources or enzymatic aids like phytase, plays a crucial role in the health and performance of various animal species. While the benefits in preterm or low birth weight infants remain inconclusive, significant positive impacts have been observed in poultry and livestock. These findings highlight the importance of optimizing phosphorus sources and supplementation strategies to enhance growth, bone health, and reproductive performance in animals.
