ABSTRACT
The polyunsaturated fatty acid (PUFA) content of M. longissimus thoracis was determined in
Hereford, Limousine and Charolais fattening bulls fed concentrate and maize or grass silage as the
basic feed for 7 months. The PUFA n-3 content was higher in Charolaise bulls than in other breeds,
and was significantly higher in animals fed on grass than on maize silage. The ratio of PUFA n-6/n-3
was the most advantageous in Hereford bulls.
