摘要
为研究河北省不同地区、不同营养水平和日粮组成的养殖场饲料营养成分,从日粮结构、干草品质、青贮饲料质量不同的牛羊养殖场采集不同饲养阶段的精料、干草、青贮等样品,测定干物质、粗蛋白质、粗灰分、钙、磷、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)、总能等饲料营养成分。结果表明:不同养殖场相同种类原料及相同饲养阶段的饲料营养成分差异较大,存在饲料营养不均衡问题。由此可见,需要继续加强监督和检测反刍动物饲料,以确保河北省反刍动物饲料产品的质量安全。
The purpose of this study was to monitor feed nutrients of different areas,levels and composition of cattle and sheep farms in Hebei province.Samples of concentrate,hay and silage for different breeding stage were collected from cattle and sheep farms of different diet structure and quality of hay and silage.Dry matter,crude protein,crude ash,Ca,P,neutral detergent fiber(NDF) and acid detergent fiber(ADF)were determined. The results showed that feed nutrition had great differences among different farms in the same kind of raw materials and at the same breeding stage,dietary nutrition was unbalanced.Therefore,we need to continue to strengthen supervise and inspect ruminant animal feed,to ensure the quality and safety of feed for ruminant animal products in Hebei province.
