This experiment was carried out to investigate the effect of kaolin supplementation from 1 % to 6 % on the performance of egg type chickens of babcock. The results obtained were as follows 1. Body gain of chicken fed the different levels of kaolin was not affected by the levels of kaolin supplementation. There was no difference on the body gain between control treatment and kaolin-supplemented treatments, and between kaolin-supplemented treatments. 2. Feed intake of chicken fed the different levels of kaolin was slightly increased as the levels of kaolin supplementation were increased. However, there were no statistical differences between treatments. 3. Feed conversion of chicken fed the different levels of kaolin was slightly decreased as the levels of kaolin supplementation were higher. However no statistical differences were found out on the feed conversion between treatments. 4. In the economical analysis, total feed cost was slightly higher as the levels of kaolin supplementation were higher. Feed cost required per ㎏ body gain was slightly decreased till the 3 % supplementation of kaolin and greatly increased above 4 % supplementation of kaolin. Feed cost of the kaolin-supplemented treatments was slightly higher compared with that of control-treatment.
