Figures & data

Table 1. Chemical composition, dissolvable nitrogen, tocopherol content (mg/kg DM), total FA content (g/kg DM) and FA composition (g FA/kg FA) of raw and micronized rapeseeds.

Figure 1. Effect of micronization and vitamin E on crude fat disappearance. Whole flaked raw rapeseed without vitamin E (RR0), micronized whole flaked rapeseed without vitamin E (MR0), whole flaked raw rapeseed supplemented with 200 mg/kg DM vitamin E (RR200), micronized whole flaked rapeseed supplemented with 200 mg/kg DM vitamin E (MR200). Error bars represent the standard error of the mean. The interaction between micronization and incubation time and the interaction between vitamin E and incubation time were not significant.
