Effects of steam conditioning at low and high temperature, expander conditioning and extruder processing prior to pelleting on growth performance and nutrient digestibility in nursery pigs and broiler chickens

In conclusion, hydro-thermal processing, in particular extruder processing, improved G:F for nursery pigs due to improved digestibility. For broiler chickens, all hydro-thermal processing increased starch digestibility, but due to reduced feed intake of the expanded and in particular the extruded diets, only steam conditioning before pelleting improved growth rate and feed utilisation.
