Improving the quality of oilmeals through manufacturing technology. - (:unkn) unknown
Research by INRA and EURETEC in France on the effect of technological treatments during production on the nutritional characteristics of rapeseed and sunflower oilmeals is reported. Results indicated that the optimum technology for production depended on whether the oilmeals were destined for feeding ruminants or monogastric species. Experiments with ruminants showed that control of temperature during grinding of rapeseed and sunflower oilmeals improved intestinal digestibility of protein. In poultry there was a correlation between soluble nitrogen and metabolizable energy contents (ME) of rapeseed meal and the amount of heat applied during processing. Values for ME were different in cocks with or without calcium. High temperatures during production decreased ME of the oilmeal in cocks without caecectomized cocks (1624 and 2033 kcal/kg) at temperatures of 130 and 70C, respectively.
