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.

Cette composition pour la désodorisation des déjections animales telles que les lisiers, en particulier les lisiers de porc, est caractérisée par le fait qu'elle comprend: (a) au moins un superphosphate simple; (b) au moins un composé choisi parmi l'acide undécylénique, ses esters et ses esters polyoxyalkylénés; et éventuellement (c) du perborate de sodium. Le constituant (a) est notamment un superphosphate simple à environ 16- 18 % en poids de P2O5. Le constituant (b) est notamment l'undécylénate de méthyle. La composition est formulée par exemple pour pouvoir traiter les déjections animales par jusqu'à 10000 ppm environ du constituant (a); jusqu'à 1000 ppm environ du constituant (b); et jusqu'à 500 ppm environ en O2 actif du constituant (c), ces quantités étant calculées par rapport au poids des déjections animales à traiter.
