High rumen degradable starch decreased goat milk fat via trans-10, cis-12 conjugated linoleic acid-mediated downregulation of lipogenesis genes, particularly, INSIG1

^a-b Means within the same row with different superscripts differ significantly (P < 0.05)
^cTreatments were the LRDS diet (RDS = 20.52%), MRDS diet (RDS = 22.15%), and HRDS diet (RDS = 24.88%) with similar total starch contents
^dPopulations determined based on quantitative PCR using primers designed to target different members of Butyrivibrio/Pseudobutyrivibrio group, S. bovis, and P. acnes
^eSEM Standard error of mean
