Abstract

Based on the potential benefits to human health, there is interest in developing sustainable nutritional strategies to enhance the concentration of long-chain n-3 fatty acids in ruminant-derived foods. Four Aberdeen Angus steers fitted with rumen and duodenal cannulae were used in a 4 x 4 Latin square experiment with 21d experimental periods to examine the potential of fish oil (170) in the diet to enhance the supply of 20: 5n-3 and 22 : 6n-3 available for absorption in growing cattle. Treatments consisted of total mixed rations based on maize silage fed at a rate of 85 g DM/kg live weight(0.75)/d containing 0, 8, 16 and 24g FO/kg diet DM. Supplements of FO reduced linearly (P
