In the classic point of view, it has well known that the tangle is the mineral source, especially iodide. However, there are few reports that the tangle can be used the high-protein source. With the consideration whether the tangle can be used as a protein source as well as one of the foodstuff or not, this studies is done by animal experiment.
The Albino rats to be examined were fed on the basal diet (Table 1) and the others including the polished tangle by weight 2%, 30, 4% and 5%, as experimental diets, for 4 weeks. respectively.
The weight gain(Fig. 1), total amount of diet intake (Fig. 2), total water intake;Fig. feed efficiency ratio (Fig. 4) and protein efficiency ratio (Fig. 5) was measured by each ;reek. respectively. In addition, organ weight (Fig. 6) and blood study (Fig. 7, Fig. 8) was also analyzed at the end of the experiment.
As the results of this study, growth rate, that is, weight gain, feed efficiency ratio and protein efficiency ratio in all experimental groups increased more than those of the contrc group. Moreover, it was also found that weight gain, feed efficiency ratio, protein efficiency ratio by feeding on the 2 percent tangle group was higher than the corresponding values e all experimental groups. However, feed intake and total water gain were the most by feeding on the 5o tangle group. This result may be interpreted to show that the total content of sod ium includes more than enough in the feed intakes.
To obtain further information concerning the effect of the tangle-dietary conditions on the growth rate of Albino rats, it was measured the organ weight. In the adrenal and spleen, the total weight by feeding on the all experimental groups were decreased more than that in the case of the control group. In the other hand, in the liver the weight by feeding on the high ,concentration groups 0%, 5% tangle diets) were not higher than the control group, while in
the case of the low concentration groups (2%, 3o tangle diets) were higher than that of the control group.
When it was observed the blood components, total protein, hemoglobin, sodium, potassium,. white blood cell and red blood cell of rats, the content of white blood cell by feeding on all. experimental groups were lower than that by feeding on the control group, but it was also clear that in the other components except white blood cell in blood the contents by feeding on all experimental groups were similar to that in the case of the control groups.
However, in the 5% tangle group, the content of sodium was the lowest of all experimental groups, where as the content of potassium was the highest of all experimental groups.
