Abstract

Preceeding report1) showed that addition of the boiled extract of several shell-fishes at about 3% level resulted in a noticeable chick growth response. Since it can be presumed that the response may be most probably due to the APF which was extracted from the viscera, a study has been made to see the effectiveness of an autolyzed viscera to chick growth and further to fractionate the growth-promoting principles. The results can be summarized as follows.<br> 1. Supplementation of an autolyzed viscera at a 1.7 per cent dry basis level gave a remarkable growth response of chicks fed a basal ration of all-vegetable protein.<br> 2. Addition to 100g basal ration of 0.27g of the activated charcoal adsorbate which is equivalent to 2.8g of the dried autolyzate, resulted in growth promotion of one-month old chicks during six-week feeding as contrasted to a negative result on addition of 1.35g of the non-adsorbed fraction.<br> 3. It has been found that the adsorbed fraction promoted both body growth and the development of the gonad, whereas the non-adsobate apparently promoted only the latter.
