| 摘 要： | 采用饲料常规分析方法、范氏洗涤纤维和两级离体消化法对多花黑麦草不同生长时期的常规营养成分、范氏纤维和体外消化率进行了测定.结果表明:贵草1号多花黑麦草随着生育期的延长,粗蛋白、Ca和P含量以及体外消化率逐渐下降,范氏纤维指标逐渐升高.在抽穗期粗蛋白水平最高,Ca和P相对也较高,贵草1号多花黑麦草刈割饲用的最佳时期是抽穗初期.

| Abstract: | The conventional nutrient components, different fibers and external digestion rate of Guicao 1 at different growth stages was determined to investigate the optimum harvest time. The results showed that the crude protein, Ca and P content, and external digestion rate decreased and fiber index increased with prolongation of its growth period. The crude protein content reached the maximum, and the content of Ca and P was at the relative high level at heading stage. The optimum harvest time of Guicao 1 is at fi... |
