In modern livestock industry, the use of antibiotics in the diets was strictly prohibited. Currently many additives are studied and used as antibiotic substitutes. Among them, we reviewed the effects of supplement charcoal in monogastric livestock`s feed additives. Supplement charcoal in diets showed improvement of growth performance and improved immune response to mycotoxin. Moreover, in faeces of fattening pigs, charcoal reduced emission of noxious gases and faecal pH and fecal microflora. The use of charcoal as feed additives has a positive benefit on livestocks.

The objective of this study was to investigate the effects of Essential oils (EO) on the storage and improvement of quality of dog food. These treatments were as follows : CON (ether extract (EE)/ crude protein (CP) ratio 〈 0.5), and TRT (EE/CP ratio > 0.5). In the test for antioxidant effect, EO was sprayed to the food surface to observe the delay of corruption by external observation. In the test for quality improvement, the sample was diluted and the microorganism was observed. With regard to decayed time, storage time was improved in EO treatment than CON on 1.1 days. Lactobacillus content was significantly increased (P 〈 0.05) in EO treatment than CON. Salmonella and E. coli contents were significantly decreased (P 〈 0.05) in EO treatment than CON. In conclusion, antioxidant function and storage stability of the feeds with the EE/CP ratio above 0.5 were improved by EO supplementation on dog diets. The quality of the feed was improved by controling contents of pathogen microorganisms.
