The Effect of Forage Source and Concentrated Liquid Feedstuff Supplementation on Improving the Synchronization of Ruminant Dietary Energy and Nitrogen Release In Vitro

This study aimed to investigate the effect of supplementation with a mixture molasses and condensed fermentation solubles (M-CMS) in different synchronization diets formulated forage sources an attempt improve efficiency by M-CMS. In first experiment, three levels M-CMS (N: 0%; L: 1.75%; H: 3.50%) were supplied or without corn silage evaluate on diet synchrony index (SI) 0.80. second containing (60 30% source) used effects higher SI (at 0.88). The vitro digestibility, products, microbial crude protein (MCP), gas kinetic parameters determined after 48 h fermentation. results demonstrated that improved MCP synthesis both low high SI, but did not enhance digestibility. was beneficial stability extent. It also affected fast- slow-degradation fractions during less silage. source degradation rate individual ingredients should be considered simultaneously rumen efficiency. provided practical choice further stability, even SI.
