Supplementation of feed for bulls with selenium (+50%), vitamin D3 (+300%), vitamin E (+825%), vitamin K3 (+325%) and omega-3 fatty acids (+120%) affected beef nutrient composition. Twelve bulls (½ year old) were randomly allocated to two dietary treatments; control (Con) or supplemented (Sup), and fed 170 days pre-slaughter at an amount of 1% of body weight. Daily gain and feed efficiency were equal in the two groups. Homogenate meat from left forequarter in the Sup group contained more selenium (+26%), vitamin MK4 (+123%), D (+197%), E (+318%), and had lower omega-6/omega-3 ratio (−24%) compared to Con meat. Sup meat fulfilled the requirements to be labelled by health claims and nutrient claims as: “A food item containing a significant amount of selenium, vitamin K and vitamin D". We suggest supplementation of cattle rations during the finishing period as a strategy to increase meat content of specific nutrients important to human health.

向育肥的公牛喂食可能促进健康的营养素会改变肉的成分并允许产品健康

补充硒(+ 50%),维生素D 3(+ 300%),维生素E(+ 825%),维生素K 3的公牛饲料(+ 325%)和omega-3脂肪酸(+ 120%)影响了牛肉的营养成分。十二头公牛(1/2岁)被随机分配到两种饮食疗法中。对照(Con)或补充(Sup),并在屠宰前170天以体重的1%喂食。两组的日增重和饲料效率相等。Sup组左前肢的匀质肉中硒含量更​​高(+ 26%),维生素MK4(+123%),D(+197%),E(+ 318%),并且omega-6 / omega-3含量较低与Con肉的比例(−24%)。补充肉满足健康要求和营养要求所标记的要求:“一种食物中含有大量的硒,维生素K和维生素D”。我们建议在肥育期补充牛定量作为增加肉的策略特定营养素的含量对人体健康至关重要。
