Phosphorus in Pig Nutrition
In order to reduce P excreted by pigs, P dietary supply should be better adjusted to the requirements and strategies to improve P availability should be implemented. The use of a feeding system relying on P apparent digestibility is recommended. This allows the reduction of safety margins when formulating pig diets, resulting in a decrease in P excretion. Low digestibility of P in feed ingredie...
متن کاملPhosphorus Nutrition of Ruminants
Most Australian soils are derived from parent material which is low in phosphorus. Soils of low phosphorus status support early maturing, grass dominant pastures with a short summer growth period and hence lengthy period of senescence. Phosphorus in these grasses may be as low as 0.02 g P/100 g OM during senescence (Robinson and Sageman 1967) and may only reach 0.15 g.P/lOO g OM during active g...
متن کاملPhosphorus nutrition of mycorrhizal trees.
Globally, phosphorus (P) limits productivity of trees in many forests and plantations especially in highly weathered, acidic or calcareous profiles. Most trees form mycorrhizal associations which are prevalent in the organic and mineral soil horizons. This review critically examines mechanisms that enhance the acquisition of P by tree roots. Mycorrhizal roots have a greater capacity to take up ...
متن کاملPrecision nutrition for Merino ewes
Automatic monitoring of liveweight and weight change is now possible with walk–through weighing systems. Computer–based drafting can incorporate a range of measurements such as pregnancy status, past performance, value–for–wool and value–for–meat to implement decisions on supplementary feeding. The combination of these technologies will provide the option of allocating animals likely to give th...
متن کاملBariatric Surgery and Precision Nutrition
This review provides a literature overview of new findings relating nutritional genomics and bariatric surgery. It also describes the importance of nutritional genomics concepts in personalized bariatric management. It includes a discussion of the potential role bariatric surgery plays in altering the three pillars of nutritional genomics: nutrigenetics, nutrigenomics, and epigenetics. We prese...
