Abstract

The fatty acid (FA) composition of animal tissues is influenced by many factors including age, dietary forage to concentrate ratio, breed and energy status. Despite a high degree of bio-hydrogenation of unsaturated FA’s in the rumen, another crucial influence on tissue FA composition is the FA composition of the diet. Feeding linseed has been shown to increase omega-3 (n-3) polyunsaturated fatty acids (PUFA) in beef. Altering the fat content and composition of the bovine digital cushion has potential implications for lameness in cattle. This study aimed to test the hypothesis that cattle offered extruded linseed would show a marked difference in FA composition in the lipids of the digital cushion compared to cattle offered a diet with no linseed.
