This experiment was conducted to investigate the effects of Briquette ash addition as the substitutes for Fe at sucking arid micro-mineral matter at growing after weaning on growth, feed efficiency, heath conditions and palatability in pigs on basis of the obtained from April 1 to May 31, 1982, at pigpen, Department of Animal Sicence, Jinju Agricultural & Forestry Junior Technical College. The results obtained are as follows: 1. When fed liberally Briquette ash as the substitute for Fe at sucking, there is a superior tendency to the growth and health conditions in pigs. 2. The growth in the Briquette ash 3% addition was no significant (p$gt;0.05) differences among the other groups. But the growth in that group was superior. 3. Feed consumption was not significantly (p$gt;0.05) different between the control and the treatments. 4. Feed cost(won) required per ㎏ gain weight were 636.40(T1), 646.72(T2), 672.52(C) and 684.56(T3). 5. Hemoglobin contents in the treatments was higher than those in the control. 6. The palatability of Briquette ash was good and health conditions was nornal, too.
