Abstract

This study investigated the effect of n-6 (control group) and n-3 polyunsaturated fatty acids (PUFA) supply (treatment group unrestricted) and a short-time feed restriction for n-3 PUFA supply (treatment group restricted) on intramuscular fat content and the total fatty acid composition in different tissues (muscle, subcutaneous fat, liver, serum and erythrocytes) and lipid classes of intramuscular fat of German Simmental bulls (n=25). Exogenous n-3 PUFA caused a higher concentration of the sum of all single n-3 and n-3 long-chain polyunsaturated fatty acids (LC PUFA) in all analysed tissues. Feed restriction compared to control feeding induced a significant decrease of C18:1cis-9 in the phospholipid fraction of longissimus muscle and in subcutaneous fat. The concentration of C18:3n-3 in liver of treatment groups was between 34 and 44% higher compared to control. PUFA in serum and the sum of n-3 PUFA in erythrocytes were significantly higher in both treatment groups compared to control. The synthesis and deposition of n-3 LC PUFA seems to be tissue dependent according to different relative amounts.
