TL;DR: The higher TVA to CLA ratio in the rumen compared with milk indicated that fat supplements increased milk CLA concentration mainly by increasing ruminal production of TVA, which also implied the significant role that mammary delta-9 desaturase plays in milk CLA concentrations.

TL;DR: Results from this study suggest that substituting corn with glycerol at low level had no adverse affects on fermentation, digestion or ruminal bacteria, however, higher substitution levels may adversely affect rumen fermentation through reducing fiber digestion, acetate production and bacterial populations.

TL;DR: Feeding a high linoleic acid fat source with fish oil most effectively increased concentrations and yields of milk cis-9,trans-11 CLA and TVA and was greatest with the HLO diet and least with the HS diet.

TL;DR: Feeding fish oil as fish meal would stimulate increased amounts of milk conjugated linoleic acid (cis-9, trans-11 C18:2; CLA) and transvaccenic acid (trans-11C18:1; TVA) when the cows were fed extruded soybeans to supply additional linolesic acid suggested that fish oil increased the production of CLA and TVA from other dietary sources of linoleoic acid such as extruding soybeans.

TL;DR: Results from these experiments clearly demonstrate the ability of ruminal microorganism to transform DHA and EPA to other fatty acids causing their disappearance from cultures.
