... diet types and breed of steers on rumen fermentation and bacterial community composition in Korea during the summer seasons. Three Holstein and 3 Jersey steers were fed a high forage (HF) and a high concentrate (HC) diet for two subsequent periods of 21 days under 2 × 2 factorial arrangements. The steers received HF diet had higher pH (P < 0.05). Higher acetate concentration was ...

...roduction performance of steers. Both experiments utilized a completely randomized design. In Trial 1, maximum gas production (Gmax) and methane production decreased by 25% and 43% with the 2% calcium nitrate supplementation respectively compared to the control (P<0.05). In Trial 2, final weight and average daily gain (ADG) increased by 4.8% and 13%, respectively, with T3 compared to the control (P<0.05). A similar 43% reduction in methane production was...
