▼a This thesis comprises three experiments that aimed to study effect of ruminal acidosis, dietary manipulation, and residual feed intake on methane (CH4) emission in lactation dairy cows. |
| 520 | |
▼a The first experiment investigated the impact of subacute ruminal acidosis (SARA) challenge feeding on enteric CH4 emission from lactating dairy cows fed diets differing in forage level, thus to determine the potential of using enteric CH4 measur |
| 520 | |
▼a The second experiment evaluated the effects of readily rumen-available carbohydrate source (refined starch vs. dextrose) and its interaction with level of rumen degradable protein (RDP) on lactation performance, ruminal parameters, CH4 emission, |

▼a The third experiment studied if genotypic RFI was reliable to reflect feed conversion efficiency, and if differences in RFI may be explained in part by differences in CH4 emission, general behavior (including standing vs. laying down), feeding b |
| 520 | |
▼a Results indicated that differences in RFI may not be explained by CH 4 emission, feeding, or chewing behavior. Results from the experiments suggested that ruminal pH may have a lag effect on CH4 emission, cows fed a diet of 28.1% starch and 4.6% |
