The current study examined the effect of supplementing lambs with algae. Forty, three month old lambs were allocated to receive a control ration based on oats and lupins (n=20) or the control ration with DHA-Gold™ algae (~2% of the ration, n=20). These lambs came from dams previously fed a ration based on either silage (high in omega-3) or oats and cottonseed meal (OCSM: high in omega-6) at joining (dam nutrition, DN). Lamb performance, carcase weight and GR fat content were not affected by treatment diet (control vs algae) or DN (silage vs OSCM). Health claimable omega-3 fatty acids (EPA+DHA) were significantly greater in the LL of lambs fed algae (125±6mg/100g meat) compared to those not fed algae (43±6mg/100g meat) and this effect was mediated by DN. Supplementing with algae high in DHA provides a means of improving an aspect of the health status of lamb meat.
本研究考察了给羔羊补饲藻类的效果。40只3月龄羔羊被分配接受基于燕麦和羽扇豆的对照日粮（n = 20）或添加了DHA - Gold™藻类的对照日粮（约占日粮的2%，n = 20）。这些羔羊的母羊在配种时曾分别饲喂基于青贮饲料（富含ω-3）或燕麦和棉籽粕（OCSM：富含ω-6）的日粮（母羊营养，DN）。羔羊的生长性能、胴体重和GR脂肪含量不受处理日粮（对照与藻类）或DN（青贮饲料与OCSM）的影响。与未饲喂藻类的羔羊相比，饲喂藻类的羔羊后腿肉中可用于健康声明的ω-3脂肪酸（EPA + DHA）显著更高（125±6mg/100g肉对43±6mg/100g肉），且这种影响受DN介导。补饲富含DHA的藻类提供了一种改善羔羊肉健康状况的方法。
