AusScan Energising Feed Grain Evaluation

AusScan calibrations for pig faecal digestible energy and ileal DE for cereal grains have been upgraded on completion of Pork CRC Project 4B-117, ‘Strengthening the AusScan pig DE, DE intake index NIR calibrations’. The project determined pig ileal and faecal DE and faecal DE intake index of 67 new grains: 22 wheat, 13 barley, 8 triticale, 4 sorghum and 20 maize samples. Improved accuracy and robustness were also achieved by adding this data, according to Charles Rikard-Bell, Manager Commercialisation and Research Impact, with Australasian Pork Research Institute Limited (APRIL). “The NIR calibrations show significant improvement due to the larger number of new samples and range of cereals added,” Dr Rikard-Bell said. Since the last update in 2013, significant new cereal data has been added to the calibration dataset. The revised calibrations have improved the faecal DE prediction by 22 per cent and can now also predict the faecal DE of maize.
