Extract

Increasing the n-3 polyunsaturated fatty acid (PUFA) content of ruminant products may be important in reducing the incidence of cardiovascular diseases in man. However, there is some evidence to suggest that dietary PUFA are extensively biohydrogenated in the rumen (Choi et al., 1997) whilst other results indicate that long chain PUFA present in fish oil are resistant to biohydrogenation (Ashes et al, 1992). The objective of the present study was to quantify the extent to which n-3 PUFA from different sources are biohydrogenated in the rumen and determine their effects on rumen microbial efficiency.
