Abstract

Ruminal conjugated linoleic acid (CLA) production from linoleic acid (LA) was characterized in vitro. Rumen bacteria from grain-fed cows were more active in BH than those from hay-fed cows. Particle-associated bacteria produced more hydrogenated products leaving less CLA than the planktonic bacteria (P < 0.05). CLA production by planktonic bacteria did not always correlate to LA given; longer incubations generally decreased CLA concentration and increased c9,t11/t10,c12 ratio, especially at higher LA concentrations. The preincubated cells to LA produced more CLA than the unexposed ones and the increase was more evident with c9,t11 CLA (P < 0.05). This study provides insight into how cattle diet and LA feedings affect ruminal CLA production.
