In the previous paper, the use of blood meal as a protein source for artificial diet for the silkworm was outlined. In this paper, chicken commercial formula feed was used as a substitute component to maintain certain physical properties of the artificial diet. The cocoon quality of the silkworms reared on an artificial diet consisting of chicken commercial formula feed and blood meal was found to be superior to that of the controls reared on mulberry leaves. Chicken commercial formula feed was much cheaper in comparison with cellulose powder and starch which were used as shaping and solidifying substances for the artificial diet. Furthermore, it was confirmed that chicken feed mixed with blood meal was economical for use as artificial diet for silkworms.
