Moeini Associate Professor, Department of Animal Science, Faculty of Agriculture, Razi University, Kermanshah, Iran M. Sori Associate Professor, Department of Animal Science, Faculty of Agriculture, Razi University, Kermanshah, Iran Journal Article 1970 01 01 In this study the possibility of producing a new compound to prevent ruminal acidosis were studied using common buffers, minerals and herbs, based on parameters such as: ability to maintain pH, acidogenic value (AV), amount of in vitro dry matter disappearance (IVDMD) and the AV/INVDMD ratio in high-concentrate diet in an in vitro batch culture. This study performed in a completely randomized design with four experiments. In the first experiment, the treatments were the buffers (sodium bicarbonate, potassium bicarbonate, magnesium oxide, sodium bentonite and zeolite) in the level of 1% DM of the ration, and the herbs (anise, rosemary, pepper, marjoram, cinnamon and garlic) in the level of 1% DM of the ration and minerals (cobalt, copper, manganese, selenium and zinc) used in one part per million units of the diet. In the second and third experiments, the treatments were the various components of buffers, herbs and minerals, in the level of 1% DM of the ration. The compound 1 (29.5% sodium bicarbonate, 25% magnesium oxide, 18% sodium bentonite, 10% anise, 9% garlic and 8.5% rosemary) had a significant effect on performance in the third experiment which was named "Rumenobuffer". In the fourth experiment, the Rumenobuffer was tested in comparison with sodium bicarbonate and rosemary. The results of the first experiment indicated that sodium bicarbonate, potassium bicarbonate, magnesium oxide and rosemary had significant effects on pH, acidogenic value and IVDMD compared to other treatments (p In this study the possibility of producing a new compound to prevent ruminal acidosis were studied using common buffers, minerals and herbs, based on parameters such as: ability to maintain pH, acidogenic value (AV), amount of in vitro dry matter disappearance (IVDMD) and the AV/INVDMD ratio in high-concentrate diet in an in vitro batch culture.
