1商业化牛场泌乳奶牛氮磷营养代谢调控与管理策略对环境安全的研究显示文摘研究结果表明,奶牛场日常活动中排放的过多氮和磷对环境造成一定程度的污染,而通过优化饲养和管理要素被认为是减少粪尿中氮和磷排放的重要策略。因此,本试验旨在通过评估奶牛群体中氮和磷的利用效率,研究日粮和管理要素对提高营养素的利用效率和减少氮和磷排放的影响。试验选用64个商业化奶牛场,精粗比为50∶50,基础日粮由牧草青贮和玉米青贮组成。试验结果显示,氮和磷的采食量分别为562 g/d(CP含量为16.4%)和84.8 g/d(P含量为0.4%),单产水平平均为29.7 kg/d,氮和磷的利用效率分别为25.8%±2.9%和31.9%±4.5%,通过控制日粮粗蛋白质的采食来调控日粮氮能在很大程度上降低氮的排放(R2=0.70)且优于日粮磷的调控降低磷的排放(R2=0.30)。尽管常用饲料原料中磷含量较高,但氮利用效率的提高有助于提高磷的利用效率。而分群饲喂、周期的日粮配给及选择不同的饲喂系统等管理策略在提高氮和磷的利用效率上不能产生持续的作用。但通过优化氮和磷的利用效率能降低单位乳生产中氮和磷的浪费且分别能减少氮和磷排泄的17%和35%。当考虑泌乳群体和农场土地的利用效率时,营养和群体管理策略在减少氮和磷的排放上就会受到一定程度的限制。通过日粮氮和磷的调控能分别降低每公顷土地上约11%的奶牛群体氮排泄和少于17%奶牛群体磷排泄。结果表明,商业化牧场中应根据实际奶牛氮和磷的需求来调控日粮中氮和磷的摄入,不但能提高乳的生产效率而且是降低泌乳群体中氮和磷排泄的可行策略。Arriaga H 张养东 2009中国畜牧兽医2009,36,6:2
