Effects of Adding Corn Dried Distiller Grains with Solubles (DDGS) to the Dairy Cow Diet and Effects of Bedding in Dairy Cow Slurry on Fugitive Methane Emissions.

Massé DI, Jarret G, Benchaar C, Hassanat F - Animals (Basel) (2014)

Bottom Line: The specific objectives of this experiment were to investigate the effects of adding 10% or 30% corn dried distillers grains with solubles (DDGS) to the dairy cow diet and the effects of bedding type (wood shavings, straw or peat moss) in dairy slurry on fugitive CH₄ emissions.The inclusion of DDGS30 in the diet increased the daily amounts of excreted DM, volatile solids (VS), fat, neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicellulose by 18%, 18%, 70%, 30%, 15% and 53%, respectively, compared to the control diet.The addition of wood shavings and straw did not have a significant effect on daily fugitive CH₄ emissions relative to the control diet, whereas the addition of peat moss caused a significant increase of 27% (p < 0.05) in fugitive CH₄ emissions.

ABSTRACT
The specific objectives of this experiment were to investigate the effects of adding 10% or 30% corn dried distillers grains with solubles (DDGS) to the dairy cow diet and the effects of bedding type (wood shavings, straw or peat moss) in dairy slurry on fugitive CH₄ emissions. The addition of DDGS10 to the dairy cow diet significantly increased (29%) the daily amount of fat excreted in slurry compared to the control diet. The inclusion of DDGS30 in the diet increased the daily amounts of excreted DM, volatile solids (VS), fat, neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicellulose by 18%, 18%, 70%, 30%, 15% and 53%, respectively, compared to the control diet. During the storage experiment, daily fugitive CH₄ emissions showed a significant increase of 15% (p < 0.05) for the slurry resulting from the corn DDGS30 diet. The addition of wood shavings and straw did not have a significant effect on daily fugitive CH₄ emissions relative to the control diet, whereas the addition of peat moss caused a significant increase of 27% (p < 0.05) in fugitive CH₄ emissions.

animals-04-00767-f001: Effects of feeding strategy (adding 0%, 10%, 30% of corn dried distillers’ grains with solubles (DDGS)) on manure CH4 emissions (L CH4·kg−1 volatile solids (VS)) over a 4-month storage experiment.

Mentions: When compared with the 0% corn DDGS diet, the addition of corn DDGS did not have a significant effect on cumulative fugitive CH4 emissions per kg of VS (Table 2 and Figure 1). The profiles of the cumulative fugitive CH4 production were similar over the four month-storage experiment for all the treatments. However, the total daily fugitive CH4 emissions (L CH4·day−1·cow−1) showed a significant increase of 15% (p < 0.05) in the slurry from the DDGS30 diet compared to the control diet. This can be explained by the fact that the addition of DDGS30 to the diet caused a significant increase (p < 0.05) in the daily amount of feces and slurry excreted. The increase in the masses of feces, VS, fat and hemicellulose excreted were 15%, 17.9%, 70%, and 53% respectively. In this study, fugitive CH4 emissions depend mainly on the amount of VS excreted.
