Effects of partially replacing dietary corn with sugars in a dual-flow continuous culture system on the ruminal microbiome.

ABSTRACT: The objective of this study was to evaluate the effects of feeding sugars as a replacement for starch on the ruminal microbiome using a dual-flow continuous culture system. Four periods of 10 days each were conducted with 8 fermenters in a 4 × 4 replicated Latin square design. Treatments included: 1) control with corn-CON, 2) molasses-MOL, 3) untreated condensed whey permeate-CWP, and 4) CWP treated with a caustic agent-TCWP as a partial substitute for corn. Sugars were defined as the water-soluble carbohydrates (WSC) concentration. Diets were formulated by replacing 4% of the diet DM in the form of starch from corn with the sugars in byproducts. Microbial samples for DNA analysis were collected from the solid and liquid effluent containers at 3, 6, and 9 h after feeding. Bacterial communi
