The thermal gelatinization of starch, modification of fibre and denaturing of protein improves ration digestibility. Natural binding properties of feedstuffs are enhanced which increases flexibility in ingredient selection and combination. Feed is very uniform and consistent due to the process and the automated controls running the equipment. Vitamin stability is ensured through formulation and the relatively short time that the feed is being processed at a higher temperature. More information will be available in the next few months as we gain experience with feed expander technology.
Results show improvements in feed conversion consistently.
Other benefits include increased weight gain, improved intake and lower diarrhea incidence. There are advantages in starter, grower and finisher rations. Complex starter rations need to be handled carefully to ensure that the heat process does not damage specialized ingredients. The table below offers some information on results comparing regular pelleted rations and expanded feeds for swine. Advantages will be closely linked to the well established benefits of feeding high quality pelleted rations.
