Sulphur and sulphate in diets: is it a concern?

Sulphur-containing compounds are essential elements for pigs. However, there is a rising concern about the excess of sulphur sources in the diet, as sulphates could serve as a substrate for increased hydrogen sulphide production by sulphate-reducing bacteria, with effects on gut health as well as effluent composition. Based on the French feed database, the total sulphur content of raw feedstuffs can range from less than 0.5g/kg to over 10g/kg. Those different sulphur values depend on the compos
