Extract

Effective ruminal protection of dietary polyunsaturated fatty acids (PUFA) is very useful in helping to reduce microbial biohydrogenation of PUFA and results in major improvements in the ratio of polyunsaturated:saturated fatty acids (P:S) in beef muscle (Scollan et al., 2003). However, in that study the protected lipid study (PLS) used which consisted of soya beans, linseed and sunflower oils mixed to give a 2.4:1 ratio of 18:2n -6:18:3n -3, was less successful in improving the n -6:n -3 ratio in beef muscle. This study reports the effects of including in the diet a PLS with a lower ratio of 18:2n -6:18:3n -3 on the fatty acid composition of the m. longissimus.
