“…It would probably be easier to find differences in intensive feeding systems with ad libitum supply. On the other hand, the lowest values of C18:2 n ‐6, n ‐6 PUFA and the highest values of MUFA in linseed group were consistent with the results obtained by Urrutia et al . in lamb meat fed with linseed.…”

“…Thus, adding perilla seed increased the fat content in the muscle, possibly because of the higher dietary fat content. Similar ether extract trends have been found in the meat of lambs fed increasing levels of linseed (Urrutia, Mendizabal et al., ). However, the efficacy of fat deposition could not be assessed in this study, as the fat content of the liver was not assessed.…”

The effects of perilla (Perilla frutescens L.) seed on carcass traits, meat quality, antioxidant status and antioxidant gene expression in the liver and muscle of Hu lambs were investigated in this study. Sixty Hu lambs (23.02 ± 1.36 kg) were randomly divided into four experimental groups receiving diets containing 0%, 5%, 10% or 15% perilla seed (CD, 5%PFSD, 10%PFSD and 15%PFSD, respectively). The addition of perilla seed had no significant impacts on carcass traits (p > .05). There were no differences in pH, meat colour, drip loss, cooking loss or shear force among the four treatments (p > .05). Addition of perilla seed increased (p < .05) deposition of intramuscular lipids but had no effect on other chemical components in the longissimus dorsi (LD) (p > .05). The 15%PFSD diet decreased the total antioxidant capacity (T-AOC) and malondialdehyde (MDA) content in the liver (p < .05 for both) but increased the activity of these antioxidant enzymes in LD (p < .05 for both). Compared to CD, addition of perilla seed increased superoxide dismutase (SOD) and glutathione peroxidase (GPX) expression in the liver and LD (p < .05 for all). These results indicate that perilla seed supplementation in lambs' diets can increase deposition of intramuscular lipids and improve muscular oxidative status and meat quality.

“…The main way of improving the PUFA content in ruminants is the supplementation of PUFA enriched plant oils in their diets [ 8 , 9 ]. Canola and flaxseed oils, which contain an abundance of α-linoleic acid (ALA, 18:3 n -3) [ 10 , 11 ], have been of recent interest in numerous nutritional trials in order to mainly improve n -3 LC-PUFA contents including eicosapentaenoic acid (EPA, 20:5 n -3), docosapentaenoic acid (DPA, 22:5 n -3) and docosahexaenoic acid (DHA, 22:6 n -3) in sheep meat [ 12 , 13 , 14 , 15 ]. Genetic management of livestock for enhancing n -3 LC-PUFA content through selective breeding provides an alternative to nutritional manipulation and it is a cumulative and long-term approach.…”

The objective of the study was to ascertain whether human health beneficial omega–3 long-chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) content in heart, kidney and liver can be enhanced by supplementing prime lambs with graded levels of canola and flaxseed oil. Health status of the lambs, as a consequence of the supplementation, was also investigated by examining their plasma metabolites. Sixty purebred and first-cross lambs were allocated to one of five treatments of lucerne hay basal diet supplemented with isocaloric and isonitrogenous wheat-based pellets without oil inclusion (Control) or graded levels of canola oil at 2.5% (2.5C), 5% (5C), flaxseed oil at 2.5% (2.5F) and 5% (5F) in a completely randomised design. Pre-slaughter blood, post-slaughter kidney, liver and heart samples were analysed for plasma metabolite and fatty acid profiles. Summations of docosapentaenoic acid and docosahexaenoic acid, and total n-3 LC-PUFA were enhanced in the liver and kidney of 5F supplemented lambs with a marked decrease in n-6/n-3 ratio and significant breed differences detected. There were generally no deleterious impacts on animal health status. A combination of 5% oil supplementation and lamb genetics is an effective and strategic management tool for enhancing n-3 LC-PUFA contents of heart, kidney and liver without compromising lamb health.
