A study was conducted to evaluate the impact of feeding soybean meal (SBM) from low-phytate (LP) or traditional phytate (TP) soybeans on performance and excretions from growing swine. Ninety-six crossbred barrows (initial BW = 18 +/- 0.3 kg) were allocated by BW to 24 pens and fed 1 of 4 treatment diets: TP SBM without supplemental phytase; TP SBM plus 500 phytase units of phytase/kg, as-fed ba...

Phosphorus deficiency is a major constraint to crop production due to rapid binding of the applied phosphorus into fixed forms not available to the plants. This work was carried out to explain the release of soluble phosphates and its effect on plant growth as a function of phosphate solubilization by fluorescent Pseudomonas. In the current study, Pseudomonas fluorescens K 34 solubilized trical...

This paper presents data on the distribution of acid-soluble phosphorus compounds in the blood cells of a few apparently normal individuals of each of forty-six species: twenty-two mammalian, twelve avian, six reptilian, four amphibian, and two fish. Since the studies were limited by availability of material, each order is represented by only a few species, and in many instances only one blood ...

MYBURGH, S. J. & DU TOIT, J. DE V. A comparative study on the efficiency of water soluble phosphates and a dry phosphate lick for sheep fed on mature grass hay. Onderstepoort]. vet. R es. (1970), 37 (2), 127-136. In a study with adolescent Merino sheep on a diet of mature grass hay, the supplementation with phosphates alone, either in the drinking water or as a dry lick, did not prevent loss of...

Phosphorus (P) in wastes from piggeries may contribute to the eutrophication of waterways if not disposed of appropriately. Phosphorus leaching, from three soils with different P sorption characteristics (two with low P retention and one with moderate P retention) when treated with piggery effluent (with or without struvite), was investigated using batch and leaching experiments. The leaching o...

Rising temperature causes a process of phosphorus release, which can be characterized well using phosphorus release rates (VP). The objective of the present study was to investigate the major factors affecting sediment phosphorus release rates through a wetland habitat simulation experiment. The results showed that the VP of different wetland sediments were different and changed with the order ...
