다국어 초록 (Multilingual Abstract)

The reproductive traits from 39 pigs farrowed at Dept. of Animal Science, this collage and 580 pigs used in the performance test at National Livestock Breeding Station were analyzed to investigate the effects of Briquette ash addition on the substitutes for Fe injection in sucking pig when fed breeding and sucking pigs with Briquette ash.
The results obtained in this study are as follows:
1. The pig of this college(5.27㎏) had slightly heavier average weight at weaning than the purebred D. J. of National Livestock Breeding Station(5.00㎏).
2. The purebred D. J(8.3pigs, 88.3％) had higher litter size and survival rate at weaning than the pig of this college.
3. The pig of this college had slightly heavier average weight at weaning than the purebred D. J.
4. In the group equal to farrowing season and litter size at sucking, there were nonsignificant(P＞.05) differences for the reproductive traits between Briquette ash addition and Fe injection group.
5. When fed liberally Briquette ash as the substitute for Fe injection in sucking pig, there is relatively a superior tendency to the growth and health conditions in pigs. The results obtained in this study suggest that the Briquette ash addition with the substitutes for Fe be going to possible in the future.
