摘要:
The invention relates to methods for pregnancy and non-pregnancy testing and also relates to methods allowing determination of proper insemination time to establish pregnancy. The invention provides method to determine whether an inseminated female mammal is pregnant prior to a point in time at which said mammal would be expected to ovulate if non-pregnant, said method comprising taking a biological sample from said mammal prior to said point in time and testing said sample for the presence of a multiple pregnancy marker pattern (MPMP). It is preferred that said sample is tested for the relative expression of progesterone and of at least one marker selected from a group of marker proteins that each contribute to a significantly differential marker expression pattern related to the status pregnancy and is tested to determine whether said mammal is non-pregnant and may be re-inseminated.

The present invention relates to a method for extracting phosphorus from organic matter, the method comprising (a) providing phosphorus-containing organic matter, wherein the organic matter further contains calcium and/or iron; (b) adding acid and sulphate-containing water to the organic matter provided in step (a) to solubilize phosphorus, allow calcium sulphate and/or iron sulphate to form, and obtain a slurry; (c) separating the slurry obtained in step (b) into a solid fraction having a water content of at most 80 wt.%, and a liquid fraction having a water content of at least 80 wt.%; (d) adding a magnesium-containing base to the liquid fraction as obtained in step (c) to obtain phosphorus precipitate in the form of struvite.
