Summary

1. In two experiments the nutritive value for the growing pig of wheat which had been micronized at temperatures of 155°, 190° or 220°C, flaked (rolled) and then ground was compared with wheat which had either been ground, or rolled and then ground.

2. In the first experiment 60 pigs offered individually, restricted amounts of feed were used in a growth and efficiency of conversion study. In the second experiment 15 pigs were used in digestibility and nitrogen retention studies.

3. The highest micronization temperature gave a significant depression in growth rate and in efficiency of conversion of dietary dry matter as compared with the other treatments for which there were no significant differences.
