Effect of Different Rumen-degradable Carbohydrates on Rumen Fermentation, Nitrogen Metabolism and Lactation Performance of Holstein Dairy Cows

Four multiparous lactating Holstein cows fitted with rumen cannulae were fed diets varying in the amount and source of rumen-degradable carbohydrates (starch vs. sucrose) to examine their effects on rumen fermentation, nitrogen metabolism and lactation performance. A 4×4 Latin square with four diets and four periods of 28 days each was employed. Corn starch and sucrose were added to diets and c...

Effect of dietary forage sources on rumen microbiota, rumen fermentation and biogenic amines in dairy cows.

BACKGROUND Fifteen lactating Holstein dairy cows were assigned to three diets in a 3 × 3 Latin square design to evaluate the effects of dietary forage sources on rumen microbiota, rumen fermentation and biogenic amines. Diets were isonitrogenous and isocaloric, with a forage/concentrate ratio of 45:55 (dry matter basis) but different main forage sources, namely cornstalk (CS), Leymus chinensis ...

Effect of dietary concentrate on rumen fermentation, digestibility, and nitrogen losses in dairy cows.

The objective of this experiment was to investigate the effect of level of dietary concentrate on rumen fermentation, digestibility, and N losses in lactating dairy cows. The experiment was a replicated 3x3 Latin square design with 6 cows and 16-d adaptation periods. Ruminal contents were exchanged between cows at the beginning of each adaptation period. Data for 2 of the diets tested in this e...

effects of different levels of sucrose and starch in total mixed rations on rumen fermentation, nitrogen metabolism and performance of holstein dairy cows

to examine the effects of different sources of rumen-degradable carbohydrates on rumen fermentation, nitrogen metabolism and performance of holstein dairy cows, four lactating holstein cows fitted with rumen cannulae in a 4×4 latin square with four diets and four 28 day periods each, were employed. experimental diets contained different levels of pure sucrose and corn starch in which sucrose wa...

Effect of direct-fed microbials on performance, diet digestibility, and rumen characteristics of Holstein dairy cows.

The objective of this study was to determine the effect of feeding direct-fed microbial (DFM) products containing Lactobacillus acidophilus and Propionibacteria freudenreichii on the performance, nutrient digestibility, and rumen fermentation of Holstein dairy cows in midlactation. Experiments were conducted from February to May 2003. Cows were fed 1 of 3 dietary treatments: 1) 1 x 10(9) colony...
