COMPOSITIONS FOR DEODORISING ANIMAL EXCRETA, AND DEODORISING METHOD THEREFOR

摘要

A composition for deodorising animal excreta such as liquid manure, particularly from pigs, including (a) at least one simple superphosphate; (b) at least one compound selected from undecylenic acid and esters and polyoxyalkylene esters thereof; and optionally (c) sodium perborate. In particular, component (a) is a simple superphosphate with around 16-18 wt % of P2O5 and component (b) is methyl undecylenate. The composition is formulated so that animal excreta may be treated wtih, for instance, up to around 10,000 ppm of component (a), up to around 1000 ppm of component (b) and up to around 500 ppm of the active O2 of component (c), these amounts being determined on the basis of the weight of animal excreta to be treated.
