Study on digestibility and energy availability of daily food intake by the Japanese. Part 2. Horse mackerel and milk.
Four male Japanese students were fed a semisynthetic diet including rice and whole egg as protein for seven days (basal-diet period), and in the following seven days milk and then, for seven days, horse mackerel were added at the expense of part of the corn starch and sugar in the basal diet (test-diet period). Urine and feces were collected throughout all periods and the contents of protein, fat and energy in these extra were determined. The results obtained were as follows: 1) Digestibility of protein was 97.3 +/- 4.1% for milk and 96.8 +/- 2.8% for horse mackerel. 2) Digestibility of fat was 96.7 +/- 1.9% for milk and 98.6 +/- 2.6% for horse mackerel. 3) The ratio of the total available energy to intake energy (Net Energy Availability) was 92.5 +/- 2.9% for milk and 88.4 +/- 5.2% for horse mackerel.
